Detailed Description
Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
In the related art, a display panel generally adopts a C architecture (Column architecture) or a Z architecture (Zigzag architecture), wherein the C architecture is identical in TFT connection direction in the same Column, and a data line generally adopts a 1+2 pixel unit/2 pixel unit turnover mode; among them, TFT (Thin Film Transistor, TFT), namely, thin film field effect transistor, means that each liquid crystal pixel 400 on the liquid crystal display is driven by the thin film transistor integrated therein.
The Z structure is that the connection directions of TFTs in the same row are inconsistent, and data lines with different lengths can appear in the double-gate structure, and the data lines adopt row inversion.
Fig. 1 is a schematic structural diagram of a display panel with a C-frame in the related art; as shown in fig. 1, the display panel includes a plurality of pixels 400, a plurality of data lines and a plurality of gate lines, wherein the pixels 400 are arranged in rows and columns or in matrix, i.e. a plurality of pixels 400 are arranged in a row direction, a plurality of pixels 400 are also arranged in a column direction, and the plurality of data lines are longitudinally arranged and distributed and are connected with the pixels 400, and the data lines are used for providing gray scale signals (i.e. brightness signals) for the pixels 400. The gate lines are arranged in a transverse direction and connected to the pixels 400, and are used for controlling the priority of starting the pixels 400.
The pixel 400 includes three color pixel units, namely a red pixel unit R, a green pixel unit G and a blue pixel unit B, and are generally arranged in a manner of sequentially arranging the red pixel unit R, the green pixel unit G and the blue pixel unit B. The pixel 400 may mix light of a plurality of colors through the pixel units of the three colors to display the mixed light of the various colors in the display panel. The pixels 400 arranged in rows and columns or in matrix, specifically, the red pixel units R, the green pixel units G, and the blue pixel units B are arranged in rows and columns or in matrix, for example: in the row direction, the arrangement order formed after the two pixels 400 are arranged is a red pixel unit R11, a green pixel unit G11, a blue pixel unit B11, a red pixel unit R21, a green pixel unit G21, and a blue pixel unit B21; in the row direction, the pixels 400 are ordered in this order, in the case of three, four, five or more. In the column direction, there are a plurality of pixels 400, where the pixel units in the same column are the same pixel units, for example, the first pixel 400 in the first row of the first column is arranged with the red pixel unit R11, the green pixel unit G11, and the blue pixel unit B11, and then the second row of the column is arranged with the red pixel unit R12, the green pixel unit G12, and the blue pixel unit B12, that is, the pixel units in the rows of the first row, the second row, and the third row … … are all arranged identically in the same column direction, for example, the first pixel unit is the red pixel unit R, the second pixel unit is the green pixel unit G, and the third pixel unit is the blue pixel unit B. The arrangement can effectively avoid the problem of single-color/mixed-color picture saw-tooth caused by that the pixel units with the same color are not arranged on the same row or column.
The data lines comprise data lines S1, S2, S3 and S4 … … which are longitudinally arranged and transversely arranged, wherein the same data line is arranged between two pixel units and is respectively connected with the pixel units on two sides of the same data line to provide pre-charging voltage for the two pixel units. For example: the data line S1 is disposed between the red pixel unit R11 and the green pixel unit G11, where the red pixel unit R11 and the green pixel unit G11 are connected to the data line S1, and the data line S1 may also be connected to the other red pixel unit R and the other green pixel unit G in the same column in the column direction, for example, after the red pixel unit R11 and the green pixel unit G11 are connected to the data line S1, the red pixel unit R12 and the green pixel unit GR12 are also connected to the data line S1, and the red pixel unit R and the green pixel unit G which are arranged in the same column continuously are connected to the data line S1. In the same row, after the red pixel unit R11 and the green pixel unit G11 are connected to the data line S1, the data line S2 is located between the blue pixel unit B11 of the first pixel 400 and the red pixel unit R21 of the second pixel 400, and is connected to the blue pixel unit B11 and the red pixel unit R21, respectively. Similar to the data line S1, the data line S2 may be connected to other blue pixel units B and red pixel units R, for example, to the blue pixel unit B12 and the red pixel unit R22 in the column direction. The data line S3 is also similar to the data line S1, and the data line S3 is disposed between the green pixel unit G21 and the blue pixel unit B21 and connects the green pixel unit G21 and the blue pixel unit B21, respectively. The same applies to the column direction, and the data line S3 connects the green pixel cell G22 and the blue pixel cell B22. The data lines S1, S2 and S3 can be used to connect the pixel units in the two pixels 400 in the same row, that is, the two pixels 400 in the same row can be controlled to output single color or mixed color. Further, the pixels 400 of two columns can be controlled by the data lines S1, S2, and S3. The subsequent data lines S4, S5, and S6 may be similar to the data lines S1, S2, and S3, for example, the data lines S4 are similar to the data lines S1, and each connect the red pixel unit R and the green pixel unit G of the same column of pixels 400, the data lines S5 are similar to the data lines S2, each connect the red pixel unit R and the blue pixel unit B of an adjacent column of pixels 400, and the data lines S6 are similar to the data lines S3, each connect the green pixel unit G and the blue pixel unit B of the same column of pixels 400. And so on with other data lines in relation to the pixel elements in pixel 400.
For the C architecture, the inversion of 2 pixel units by the data line has reverse polarity precharge, i.e., the positive and negative inversion of the pixel units of the same color in the adjacent pixels 400. For example, in the case where the red pixel unit R11 of the pixel 400 of the first row is precharged to a positive voltage, the red pixel unit R21 of the pixel 400 adjacent thereto in the first row is precharged to a negative voltage. Similarly from the column direction, in the case where the red pixel cell R11 in the first row is precharged to a positive voltage, the red pixel cell R12 of the pixel 400 of the same column in the second row is precharged to a negative voltage. The same applies to pixel cells of other colors. For example, in the first pixel 400 of the first row, the red pixel unit R11 is precharged to a positive voltage, the green pixel unit G11 is precharged to a positive voltage, and the blue pixel unit B11 is precharged to a negative voltage. In the pixels 400 adjacent to the same row as the pixel 400, the red pixel unit R21 is precharged to a negative voltage, the green pixel unit G21 is precharged to a negative voltage, and the blue pixel unit B21 is precharged to a positive voltage. Similarly, in the adjacent pixels 400 in the same column as the pixel 400, the red pixel unit R12 is precharged with a negative voltage, the green pixel unit G12 is precharged with a negative voltage, and the blue pixel unit B12 is precharged with a positive voltage. When the display panel is used for displaying, the polarities of the voltage signals provided by the two adjacent data lines are opposite, so that the polarities of the voltages of the two pixels 400 positioned in the two adjacent rows are opposite on the same data line.
The gate lines include a gate line G1, a gate line G2, and a gate line G3 … …, where all the gate lines are arranged transversely and longitudinally, and in general, the priority of each of the gate lines G1, G2, G3, G4, and G5 is lowered, that is, the pixel unit connected to the gate line G1 is turned on earlier than the pixel unit connected to the gate line G2. For example: the red pixel units R of the first row are all connected with the gate line G1, the green pixel units G of the first row are all connected with the gate line G2, the blue pixel units B of the first row are connected with the gate line G1 or the gate line G2, wherein the two pixel units connected with the same data line are not connected on the same gate line, namely, when the blue pixel units B are connected with the red pixel units R together with one data line (such as the data line S2), the blue pixel units B are connected with the gate line G2 so as to determine that one of the red pixel units R or the blue pixel units B is firstly lit and the other is lit. Similarly, when the blue pixel unit B is connected to one data line (such as the data line S3) together with the green pixel unit G, the blue pixel unit B is connected to the gate line G1 to determine whether one of the green pixel unit G or the blue pixel unit B is lit first and the other is lit later. The pixels 400 for the second row, the pixels 400 for the third row, etc. are similar. Assuming that the pixel cell connected to the gate line G1 is preferentially bright, in the first row, the red pixel cell R and a portion of the blue pixel cell B are preferentially bright compared to the pixel cells connected to the same data line, for example, between the red pixel cell R11 and the green pixel cell G11, the red pixel cell R11 is first bright in the case of pre-charge. For example, between the blue pixel unit B11 of the first pixel 400 and the red pixel unit R21 of the second pixel 400, the blue pixel unit B11 is connected to the gate line G2, and the red pixel unit R is lit first in the case of pre-charge.
Fig. 2 (a) is a diagram showing a pre-charge effect of the display panel of fig. 1 for displaying color mixing of red pixel cells and green pixel cells; fig. 2 (b) is a diagram showing a pre-charge effect of the display panel of fig. 1 for displaying color mixing of blue pixel cells and green pixel cells; fig. 2 (c) is a diagram showing a priming effect of the display panel of fig. 1 for displaying color mixing of blue pixel cells and red pixel cells; as shown in fig. 2 (a), 2 (b) and 2 (C), when the display panel performs display, for example, in the case of color mixing of the red pixel unit R and the green pixel unit G, the data line is similar to a conventional C frame, wherein the potential of the red pixel unit R11 connected to the data line S1 is precharged to a positive voltage, the potential of the green pixel unit G11 is precharged to a positive voltage, the potential of the red pixel unit R12 is precharged to a negative voltage, the precharging of the green pixel unit G12 is a negative voltage, and other pixel units connected to the data line S1 can be similarly determined. Since the red pixel unit R is connected to the gate line G1 and the green pixel unit G is connected to the gate line G2, the gate line G1 has a higher priority than the gate line G2, and thus the red pixel unit R is turned on before the green pixel unit G, so that the potential of the red pixel unit R is reversed pre-charged.
In the red pixel unit R and the blue pixel unit B on the data line S2, RG color mixing is performed, that is, when the blue pixel unit B is dark, the potential of the blue pixel unit B11 is precharged to a negative Vcom, the potential of the red pixel unit R21 is precharged to a negative voltage, the potential of the blue pixel unit B12 is precharged to a negative Vcom, and the potential of the red pixel unit R22 is precharged to a positive voltage. The same can be said for other pixel cells connected to the data line S2. Meanwhile, the blue pixel unit B is dark, the potential of the blue pixel unit B21 is pre-charged to the positive Vcom, the potential of the green pixel unit G21 is pre-charged to the positive voltage, the potential of the blue pixel unit B22 is pre-charged to the positive Vcom, and the potential of the green pixel unit G22 is pre-charged to the negative voltage. The same applies to the other unit pixels 400 connected to the data line S3. In the same pixel unit, the same polarity pre-charge brightness > Vcom pre-charge brightness > opposite polarity pre-charge brightness. Therefore, in the above, the red pixel unit R21 and the red pixel unit R22 connected to the data line S2 are both the luminance for displaying Vcom pre-charge, and the green pixel unit GR21 and the green pixel unit GR22 connected to the data line S3 are also the luminance for displaying Vcom pre-charge. The red pixel unit R11 and the red pixel unit R12 connected to the data line S1 show the brightness of the opposite polarity precharge, and the green pixel unit G11 and the green pixel unit G12 show the brightness of the same polarity precharge as shown in fig. 2 (a). That is, the red pixel unit R on the data line S2 and the green pixel unit G on the data line S3 display higher luminance than the red pixel unit R and the green pixel unit G on the data line S1. Thus, there is a difference in brightness between two adjacent pixels 400, one bright and one dark, resulting in vertical lines of the display panel when displayed. When the red pixel unit R and the blue pixel unit B are mixed, the display effect after the mixed color can be obtained according to the same principle as that described above as shown in fig. 2 (c); as can be obtained by the same procedure as described above, when the green pixel unit G and the blue pixel unit B are mixed, the display panel may display vertical lines, and the display effect after the mixed color is as shown in fig. 2 (B).
For the red pixel unit R, the green pixel unit G, and the blue pixel unit B, reverse polarity precharge x, vcom precharge Δ, or homopolarity precharge O is performed at the time of color mixing display. Firstly, determining which pixel unit connected to the same data line is firstly lightened, and then judging and pre-charging according to the positive and negative polarities of the pixel units. When the display screen displays the color mixing screen, the color mixing can be performed by three schemes, and the color mixing is illustrated by taking the case that the blue pixel unit B is dark, the red pixel unit R and the green pixel unit G are mixed, the data line S1 is connected with the red pixel unit R11 to be precharged with a positive voltage, the green pixel unit G11 to be precharged with a positive voltage, the red pixel unit R12 to be precharged with a negative voltage, and the green pixel unit G12 to be precharged with a negative voltage. Since the red pixel units R in the same row are turned on before the green pixel unit G, the red pixel unit R11 is pre-charged with opposite polarity, and the red pixel unit R connected to the data line S1 may be determined to be pre-charged with opposite polarity by the red pixel unit R12, where the determining process of the red pixel unit R12 is as follows: the first row is that the red pixel unit R11 is lit first and the green pixel unit G11 is lit later, and since the red pixel unit R11 and the green pixel unit G11 are both precharged to be positive voltage, the green pixel unit G11 is the same polarity precharge O, and since the green pixel units G connected to the data line S1 are both turned on later than the red pixel units R in the same row and the polarities of the precharge potentials of both are the same, either both are positive voltage or both are negative voltage, it can be determined that the green pixel units G connected to the data line S1 are both the same polarity precharge O. Continuing to the red pixel cells R12 of the second row, since the pixel cells of the first row are higher than the pixel cells connected to the second row, for example, the red pixel cells R of the first row are connected to the gate line G1, the green pixel cells G of the first row are connected to the gate line G2, the red pixel cells R of the second row are connected to the gate line G3, and the green pixel cells G of the second row are connected to the gate line G4. The second row of red pixel units R12 is turned on after the first row of green pixel units G11, i.e., the second row of red pixel units R12 is determined based on the first row of green pixel units G11, wherein the first row of green pixel units G11 is precharged with a positive voltage, the second row of red pixel units R12 is precharged with a negative voltage, and the green pixel units G11 and the red pixel units R12 are reversed in polarity, so that the red pixel units R12 are reversed in polarity. The red pixel unit R and the green pixel unit G connected to the data line S1 can be obtained in the same manner.
The process of determining which pre-charge mode the pixel cells on the data line S2 and the data line S3 belong to is similar to that of the pixel cell of the data line S1, wherein, when the red pixel cell R and the green pixel cell G are mixed, the blue pixel cell B needs to be controlled to be dark, that is, the blue pixel cell B needs to be pre-charged to be zero potential, and the display part is gray. For the red pixel unit R connected to the data line S2, since the blue pixel unit B is dark, the red pixel unit R connected to the data line S2 is directly precharged with the Vcom voltage, that is, vcom precharge delta. The same applies to the data line S3, so that the data line S3 is connected to the green pixel unit G to be directly precharged with the Vcom voltage, that is, vcom precharge delta.

Fig. 4 (a) is a diagram showing a pre-charge effect of the display panel of fig. 3 for displaying color mixing of red pixel cells and green pixel cells; fig. 4 (b) is a diagram showing a pre-charge effect of the display panel of fig. 3 for displaying a color mixture of a blue pixel unit and a green pixel unit; FIG. 4 (c) is a diagram showing the effect of priming in which the display panel of FIG. 3 displays a color mixture of blue and red pixel cells; as shown in fig. 3, 4 (a), 4 (b) and 4 (c),
The Z architecture adopts column inversion, because one data line is connected with three colors, and the same-color pixel units in adjacent pixels 400 of a single-color or mixed-color picture are pre-charged differently, so that vertical lines are caused, especially, the picture with mixed light of a green pixel unit G and a blue pixel unit B is pre-charged in the middle column of the figure 4, wherein in the adjacent pixels 400, the green pixel unit G and the blue pixel unit B in the first pixel 400 column are both Vcom pre-charged delta, and the green pixel unit G and the blue pixel unit B in the second pixel 400 column adjacent to the first pixel are pre-charged with the same polarity, so that the brightness generated by the pixels 400 in the two columns is different, and the two connected pixel units in the two adjacent pixel 400 columns are overlapped differently, so that the vertical lines are easier to be seen. For the color mixing of the red pixel unit R and the blue pixel unit B, the display effect after the color mixing can be obtained according to the same principle as that described above as shown in fig. 4; as can be obtained by the same procedure as described above, when the green pixel unit G and the blue pixel unit B are mixed, the display panel may display vertical lines, and the display effect after the mixed color is as shown in fig. 4 (a), 4 (B) and 4 (c).
In one embodiment, in the pixel 400 architecture of the display panel, in the pixels 400 in the same column, the red pixel unit R, the green pixel unit G and the blue pixel unit B are not located in the same column, for example, the first pixel unit in the first row is the red pixel unit R, the first pixel unit in the second row is the blue pixel unit B, the first pixel unit 100 in the third row is the red pixel unit R, the first pixel unit in the fourth row is the blue pixel unit B, and so on; for example, the second pixel unit in the first row is a green pixel unit G, the second pixel unit in the second row is a red pixel unit R, the second pixel unit in the third row is a green pixel unit G, and the first pixel unit in the fourth row is a red pixel unit R. And so on, with the pixels 400 of the first and second rows as a group, the subsequent repeat stack. This arrangement causes a problem of jaggy of the monochrome/color-mixed picture that the same color pixel units do not appear on the same row or on the same column.
Fig. 5 illustrates a schematic structure of a display panel according to an embodiment of the present application; fig. 7 is a schematic diagram of another structure of a display panel with a C-frame according to an embodiment of the application. As shown in fig. 5 and 7, the display panel includes:
a plurality of pixels 400 arranged with each other, the pixels 400 including a first pixel unit 100, a second pixel unit 200, and a third pixel unit 300, the first pixel unit 100, the second pixel unit 200, and the third pixel unit 300 being pixel units of different colors; and
a first data line s1 and a second data line s2;
in each pixel 400, the first pixel unit 100 and the second pixel unit 200 are connected to the first data line s1, and the third pixel unit 300 is connected to the second data line s2.
In the present embodiment, the first pixel unit 100 may be any one of the red pixel unit R, the green pixel unit G, and the blue pixel unit B, the second pixel unit 200 may be any one of the red pixel unit R, the green pixel unit G, and the blue pixel unit B, and the third pixel unit 300 may be any one of the red pixel unit R, the green pixel unit G, and the blue pixel unit B, but the first pixel unit 100, the second pixel unit 200, and the third pixel unit 300 are not pixel units of the same color. For example, the first pixel unit 100 is the red pixel unit R, the second pixel unit 200 is the green pixel unit G, and the third pixel unit 300 is the blue pixel unit B, and in the following embodiments, those skilled in the art may adjust the colors of the first pixel unit 100, the second pixel unit 200, and the third pixel unit 300 according to the actual situation, which will not be described herein.
Similar to the above-mentioned C architecture, the plurality of pixels 400 are arranged in the first direction, and the columns are in the second direction, that is, the second direction is perpendicular to the first direction, where the arrangement may be a matrix arrangement, specifically, the first pixel unit 100, the second pixel unit 200, and the third pixel unit 300 are arranged in a matrix arrangement, and the first pixel unit 100 is taken as a red pixel unit R, the second pixel unit 200 is taken as a green pixel unit G, and the third pixel unit 300 is taken as a blue pixel unit B. In the embodiment of the present application, the pixel units may be arranged in the same manner as the above-mentioned C structure, and in the row direction, for example, the first pixel unit 100 is a red pixel unit R, the second pixel unit 200 is a green pixel unit G, and the third pixel unit 300 is a blue pixel unit B, for example: the arrangement order formed after the two pixels 400 are arranged is a red pixel unit R11, a green pixel unit G11, a blue pixel unit B11, a red pixel unit R21, a green pixel unit G21, and a blue pixel unit B21; in the row direction, the pixels 400 are ordered in this order, in the case of three, four, five or more. In the column direction, there are a plurality of pixels 400, where the pixel units in the same column are the same pixel units, for example, the first pixel 400 in the first row of the first column is arranged with the red pixel unit R11, the green pixel unit G11, and the blue pixel unit B11, and the second row of the column is arranged with the red pixel unit R12, the green pixel unit G12, and the blue pixel unit B12, that is, the pixel units in the rows of the first row, the second row, and the third row … … are all arranged identically in the same column direction, for example, the first pixel unit is the red pixel unit R, the second pixel unit is the green pixel unit G, and the third pixel unit is the blue pixel unit B. The arrangement can effectively avoid the problem of single-color/mixed-color picture saw-tooth caused by that the pixel units with the same color are not arranged on the same row or column.
In the arrangement manner described above, the order may be modified to be in the same row, that is, the blue pixel unit B11, the red pixel unit R11, the green pixel unit G11, the blue pixel unit B21, the red pixel unit R21, and the green pixel unit G21 are arranged in the same row, and the arrangement manner of each row is the same in the column direction, and the pixel units on the same column are the same color pixel units. The order in each pixel 400 may be changed to be arranged in such a manner that the blue pixel unit B, the green pixel unit G, the red pixel unit R, the blue pixel unit B, the green pixel unit G, or the like. In the above arrangement, in the pixel 400 architecture in the display panel, the pixel unit ordering of each pixel 400 is the same, for example, each pixel 400 is arranged in a manner of red pixel unit R, blue pixel unit B, and green pixel unit G, and two pixels 400 in the same row are arranged in a manner of arrangement of red pixel unit R, blue pixel unit B, green pixel unit G, red pixel unit R, blue pixel unit B, and green pixel unit G. Other ways may be directly obtained according to the actual deformation, and will not be described here again.
In addition to the arrangement described above, the arrangement in which the pixel units in the adjacent two pixels 400 are ordered differently may be adopted, for example, the arrangement in which the pixel units in the first pixel 400 in the first row are ordered as a red pixel unit R11, a green pixel unit G11, and a blue pixel unit B11, the pixel units in the second pixel 400 are ordered as a blue pixel unit B21, a green pixel unit G21, and a red pixel unit R21, and the arrangement in the first row forms a red pixel unit R11, a green pixel unit G11, a blue pixel unit B21, a green pixel unit G21, and a red pixel unit R21 may be circularly arranged in the row direction by arranging the two pixels 400 in a group, and the pixel units in each row may be arranged in the same manner as the first row. That is, the arrangement of the pixel units may be such that, in any one group of pixels 400, the order of the pixel units in one pixel 400 is different from the order of the pixel units in the other pixel 400, and in the column direction, the pixel units in the same column that hold the same color are arranged.
The first data line s1 and the second data line s2 are all data lines for providing gray scale signals (brightness signals) for the pixel units, wherein the first data line s1 and the second data line s2 are different data lines, are all a plurality of data lines, are longitudinally arranged, are all transversely arranged, are all located between two pixel units, and are connected with the pixel units on two sides so as to provide the gray scale signals for the pixel units.
In the present embodiment, for any one of the pixels 400, the first pixel unit 100 and the second pixel unit 200 are connected to the first data line s1, specifically, the first pixel unit 100 and the second pixel unit 200 in each pixel unit are connected to the same first data line s1. As shown in fig. 5, the first pixel unit 100 is a red pixel unit R, the second pixel unit 200 is a green pixel unit G, and one first data line s1 is located between the red pixel unit R and the green pixel unit G of the first pixel 400, and is connected to the red pixel unit R and the green pixel unit G respectively, and is the same in the other row directions. The other first data line s1 is located between the red pixel unit R and the green pixel unit G of the second pixel 400, and is connected to the red pixel unit R and the green pixel unit G, respectively, where the red pixel unit R and the green pixel unit G of each pixel 400 are connected to the same first data line s1.
The third pixel unit 300 of each pixel 400 is connected to the second data line s2, wherein there may be two cases where the third pixel unit 300 is connected through a single second data line s2 and is controlled according to the single second data line s2, which is equivalent to a single gate architecture, or another case where the third pixel units 300 of two adjacent pixels 400 are disposed adjacent, or remain connected through the same second data line s2 even if not adjacent.
With the structure provided in this embodiment, in one example, the first pixel unit 100 is a red pixel unit R, the second pixel unit 200 is a green pixel unit G, the third pixel unit 300 is a blue pixel unit B, and the pre-charge of the red pixel unit R, the pre-charge of the green pixel unit G and the pre-charge of the blue pixel unit B of the first pixel 400 in the first row are positive voltages, respectively, and the pixels 400 in the same row and the same column are turned over to determine, that is, the pre-charge of the red pixel unit R, the pre-charge of the green pixel unit G, and the pre-charge of the blue pixel unit B of the second pixel 400 in the same row are negative voltages; the first pixel 400 of the second row is precharged to a negative voltage for the red pixel cell R, to a negative voltage for the green pixel cell G, and to a positive voltage for the blue pixel cell B. And performing row-column analogy in sequence to obtain the pre-charge polarity of the pixel 400 architecture and the pixel units.
Fig. 6 (a) is a diagram showing a pre-charge effect of the display panel of fig. 5 for displaying color mixing of red pixel cells and green pixel cells; fig. 6 (b) is a diagram showing a pre-charge effect of the display panel of fig. 5 for displaying a color mixture of a blue pixel unit and a green pixel unit; FIG. 6 (c) is a diagram showing the effect of priming in which the display panel of FIG. 5 displays a color mixture of blue and red pixel cells; as shown in fig. 6 (a), 6 (b) and 6 (c), when performing a color mixing screen, for example: the red pixel unit R and the green pixel unit G are mixed, at this time, the blue pixel unit B is dark, the second data line s2 connected with the blue pixel unit B outputs Vcom pre-charge, and since the red pixel unit R and the green pixel unit G in each pixel 400 are connected to the same first data line s1, if the red pixel unit R is turned on, the red pixel unit R of each pixel 400 is pre-charged with opposite polarity, and the green pixel unit G of each pixel 400 is pre-charged with same polarity, at this time, the pre-charge between the red pixel unit R and the green pixel unit G between adjacent pixels 400 is not different, as shown in fig. 6 (a), so that the problem of displaying vertical lines is effectively solved.
Therefore, in the present embodiment, in the process of displaying the color mixing picture on the display panel, for example, the color mixing of the first pixel unit 100 and the second pixel unit 200 of the pixel 400 is performed, because in any pixel 400, the first pixel unit 100 and the second pixel unit 200 are connected to the first data line s1, the first pixel unit 100 and the second pixel unit 200 of each pixel 400 can maintain the same pre-charge type, so that the pre-charge brightness between the first pixel unit 100 and the second pixel unit 200 between the pixels 400 in adjacent columns is not different, and the problem of vertical streaks occurring in the process of color mixing on the display panel is solved.
In one embodiment, among the plurality of pixels 400 arranged along the first direction, two adjacent pixels 400 are taken as a group of pixel regions 500 to determine a plurality of groups of pixel regions 500, and two third pixel units 300 in each group of pixel regions 500 are connected to the same second data line s2.
The two third pixel units 300 are connected through the same second data line s2 within the same pixel region 500 such that the first data line s1 and the second data line s2 can be alternately arranged.
Wherein, the plurality of pixels 400 arranged along the first direction may be the pixels 400 on the same row; the two third pixel units 300 may be connected to each other, and one second data line s2 passes through between the two third pixel units 300 and is connected to the two third pixel units 300, respectively; it is also possible to adopt a manner that two third pixel units 300 are not adjacent but are connected by the same second data line s2.
By means of the method, the first pixel unit 100 and the second pixel unit 200 of each pixel 400 can be kept in a consistent pre-charge type, so that pre-charge brightness between the first pixel unit 100 and the second pixel unit 200 between pixels 400 in adjacent columns is not different, and the problem that vertical lines appear in the display panel in the color mixing process is solved.
In one implementation, fig. 8 is a schematic diagram showing another structure of a display panel of a C architecture in an embodiment of the present application, and fig. 9 (a) is a pre-charge effect diagram showing color mixing of a red pixel unit and a green pixel unit of the display panel of fig. 8; fig. 9 (b) is a diagram showing a pre-charge effect of the display panel of fig. 8 for displaying color mixing of the blue pixel unit and the green pixel unit; fig. 9 (c) is a diagram showing a priming effect of the display panel of fig. 8 for displaying color mixing of the blue pixel unit and the red pixel unit; as shown in fig. 8, 9 (a), 9 (b) and 9 (c), in the case where two third pixel units 300 in the pixel region 500 are not adjacent, the second data line s2 includes a first sub data line s21, a second sub data line s22 and a first connection line s23, the first connection line s23 connecting the first sub data line s21 and the second sub data line s22;
in the pixel area 500, one of the third pixel units 300 is connected to the first sub-data line s21, and the other third pixel unit 300 is connected to the second sub-data line s22.
In some implementations, for some general or conventional pixels 400, the order of the pixel units has been determined, for example, in one pixel 400, the order is sequentially red pixel unit R, green pixel unit G, and blue pixel unit B, that is, after the pixels 400 are arranged in the same row, the arrangement order of the pixel units is repeatedly arranged according to the red pixel unit R, the green pixel unit G, and the blue pixel unit B, for example: the pixel units of the two pixels 400 of the same row are arranged in the order of the red pixel unit R, the green pixel unit G, the blue pixel unit B, the red pixel unit R, the green pixel unit G, and the blue pixel unit B.
At this time, the first pixel unit 100 and the second pixel unit 200 in the same pixel 400 are easily connected to the same first data line s1, but the third pixel units 300 in the same pixel area 500 are not adjacent to each other, and the pixel 400 cannot change the position of the pixel unit, so the second data line s2 in this embodiment includes the first sub-data line s21, the second sub-data line s22 and the first connection line s23, and the first connection line s23 connects the first sub-data line s21 and the second sub-data line s22, so that two non-adjacent third pixel units 300 can also be connected to the same second data line s2, which solves the problem of vertical streaks in the color mixing process of the display panel, and can be applied to the pixels 400 ordered by various different pixel units.
The first connection line s23 may be provided as a jumper line passing through the first data line s1 connected to the first pixel unit 100 and the second pixel unit 200 of one pixel 400.
In one embodiment, in each pixel region 500, two third pixel units 300 are disposed adjacent to each other and are connected to the same second data line s2 disposed between the two third pixel units 300.
Since the two third pixel units 300 in the pixel area 500 are connected to the same second data line s2, in the case that the first pixel unit 100 and the third pixel unit 300 are mixed or the second pixel unit 200 and the third pixel unit 300 are mixed, the third pixel units 300 in the same pixel area 500 may appear, one of the third pixel units 300 forms opposite polarity precharge, the other third pixel unit 300 forms the same polarity precharge, and in the case that the third pixel unit 300 has vertical lines, at this time, by disposing the two third pixel units 300 in the pixel area 500 adjacently, the two third pixel units 300 can mutually support, even if one of the third pixel units 300 forms opposite polarity precharge, the other third pixel unit 300 forms the same polarity precharge, the luminance difference is not caused to be larger during display, and the problem of vertical lines is avoided.
Taking the first pixel unit 100 as the red pixel unit R, the second pixel unit 200 as the green pixel unit G, and the third pixel unit 300 as the blue pixel unit B as an example, the following description will be made:
for the color mixing of the red pixel unit R and the blue pixel unit B, at this time, the green pixel unit G is dark, the first data line s1 connected with the green pixel unit G outputs Vcom pre-charge, at this time, the pre-charge of the red pixel unit R is Vcom pre-charge, and the blue pixel units B of two adjacent columns of pixels 400 are adjacently arranged and connected with the second data line s2, so that one column is homopolar pre-charge, and the other column is reverse polarity pre-charge.
The color mixing of the green pixel unit G and the blue pixel unit B is similar to the color mixing of the red pixel unit R and the blue pixel unit B; at this time, the red pixel unit RG is dark, the first data line s1 connected to the red pixel unit RB outputs Vcom pre-charge, at this time, the pre-charge of the green pixel unit G is Vcom pre-charge, and the blue pixel units B of two adjacent columns of pixels 400 are adjacently arranged and connected to the second data line s2, so that one column is homopolar pre-charge, and the other column is reverse polarity pre-charge.
In one embodiment, the display panel further includes:
the first gate lines g1, each of the first pixel units 100 is connected to the first gate line g1 in arranging the pixels 400 in the first direction, respectively; and
a second gate line g2, each of the second pixel units 200 being connected to the second gate line g2, respectively, in arranging the pixels 400 in the first direction;
one of the third pixel units 300 of the pixel region 500 is connected to the first gate line g1, and the other third pixel unit 300 is connected to the second gate line g2;
The first gate line g1 and the second gate line g2 are different gate lines.
The gate lines are configured as in the above-mentioned C-frame, wherein, in the pixels arranged along the first direction, i.e. the pixels in the same row, at least two gate lines are included in the same row, so as to distinguish the start-up lighting sequence of the pixel units connected to the same data line.
In this embodiment, if the first gate line g1 has a higher priority than the second gate line g2, the first pixel unit 100 is turned on earlier than the second pixel unit 200 because the first pixel unit 100 and the second pixel unit 200 are connected to the same first data line s 1. For the third pixel unit 300 of the same pixel region 500, the third pixel unit 300 connected to the first gate line g1 is lighted earlier than the second pixel unit 200 connected to the second gate line g 2. And if the second gate line g2 has a higher priority than the first gate line g1, the opposite is true.
In other rows, a third gate line and a fourth gate line may be further disposed and connected to the pixel unit, which is similar to the first gate line and the second gate line g2, and will not be described herein.
In one embodiment, in the case where the first pixel unit 100 and the second pixel unit 200 of the pixel 400 are not adjacent, the first data line s1 includes a first cell line, a second cell line, and a second connection line connecting the first cell line and the second cell line;
In the pixel 400, a first cell line is connected to the first pixel unit 100, and a second cell line is connected to the second pixel unit 200.
For some pixels 400, the first pixel 400 and the second pixel 200 are not adjacent, such as a general or a normal pixel 400, which has determined the order of the pixel units, for example, in one pixel 400, the order is sequentially a red pixel unit R, a green pixel unit G, and a blue pixel unit B, that is, after the pixels 400 are arranged in the same row, the arrangement order of the pixel units is repeatedly arranged according to the red pixel unit R, the green pixel unit G, and the blue pixel unit B, for example: the pixel units of the two pixels 400 of the same row are arranged in the order of the red pixel unit R, the green pixel unit G, the blue pixel unit B, the red pixel unit R, the green pixel unit G, and the blue pixel unit B.
For example: the first pixel unit 100 is a red pixel unit R, the second pixel unit 200 is a blue pixel unit B, and the first pixel unit 100 and the second pixel unit 200 are not adjacent pixel units at this time:
at this time, the first pixel unit 100 and the second pixel unit 200 are to be connected to the same first data line s1 in the same pixel 400 in the manner of this embodiment, the first pixel unit 100 is connected to the first unit line, the second pixel unit 200 is connected to the second unit line, and then the first unit line and the second unit line are connected together through the second connection line, so that the first pixel unit 100 and the second pixel unit 200 can still be connected to the same first data line s1 under the condition of non-adjacent pixels, and by this manner, the pre-charge brightness between the first pixel unit 100 and the second pixel unit 200 between the pixels 400 in adjacent columns can be also not different, thereby solving the problem that the vertical streak occurs in the display panel in the process of color mixing. While being adaptable to pixels 400 of a variety of different pixel cell ordering.
The second connection line may be provided as a jumper line passing through the second data lines s2 connected to the two third pixel units 300 through one pixel region 500.
In one embodiment, among the plurality of pixel units included in the pixel region 500, the first pixel unit 100, the second pixel unit 200, the third pixel unit 300, the second pixel unit 200, and the first pixel unit 100 are sequentially arranged in this order; the pixel units in the second direction perpendicular to the first direction are the same type of pixel units.
Wherein the first direction is a row direction and the second direction is a column direction.
By arranging the pixel regions 500 in the first pixel unit 100, the second pixel unit 200, the third pixel unit 300, the second pixel unit 200, and the first pixel unit 100 in the pixel region 500 in the sequential arrangement manner, the first pixel unit 100 and the second pixel unit 200 of the same pixel 400 can be connected and arranged, and the two third pixels 400 are arranged adjacently. The first data line s1 may be directly disposed between the first pixel unit 100 and the second pixel unit 200, and the second data line s2 may be disposed between the two third pixel units 300, so that the first data line s1 is connected to the first pixel unit 100 and the second pixel unit 200, and the second data line s2 is connected to the two third pixel units 300.
By arranging the same column of pixel units as the same kind of pixel units in the column direction, i.e. the first pixel unit of the first row is the first pixel unit 100, the first pixel unit of the second row is the first pixel unit 100, and so on, and other rows and columns, the problem of single-color/mixed-color picture saw-tooth of the same-color pixel units not in one row or one column can be effectively avoided.

The second sub-signal line s12 is the same.
In addition to the problem of avoiding display of vertical lines in the above embodiment, through the first sub-signal line s11 and the second sub-signal line s12, when the first sub-signal line s11 is output, a positive Vcom voltage can be directly output, and when the second sub-signal line s12 is output, a negative Vcom voltage can be directly output, so that the number of times of turning the first data line s1 is reduced, and therefore, the power consumption is reduced in consideration of reducing the number of times of turning the first data line s1, and adjacent pixel units are turned to adjacent columns, thereby improving the charging amplitude.

As in the above embodiment, the third sub-signal lines s24 are connected to the third pixel cells 300 to be pre-charged with the positive voltage in the first row, and then the third pixel cells 300 to be pre-charged with the positive voltage in the second row, so on. The fourth sub-signal line s25 is the same.
In addition to the problem of avoiding display of vertical lines in the above embodiment, through the third sub-signal line s24 and the fourth sub-signal line s25, when the third sub-signal line s24 is output, a positive Vcom voltage can be directly output, and when the fourth sub-signal line s25 is output, a negative Vcom voltage can be directly output, so that the number of times of turning the second data line s2 is reduced, and the power consumption is reduced in consideration of reducing the number of times of turning the second data line s2, and adjacent pixel units are turned into adjacent columns to increase the charging amplitude.
