Description

Array substrate, display panel and liquid crystal display device

technical field

Embodiments of the present invention relate to liquid crystal display technology, and in particular to an array substrate, a display panel, and a liquid crystal display device.

Background technique

Currently, according to different driving modes, the pixel structure of the display panel is mainly divided into a single-gate pixel structure and a double-gate pixel structure. Compared with the single-gate pixel structure, the double-gate pixel structure has the advantages of lower production cost and less power consumption, and is widely used in display products such as mobile phones, tablet computers, and information inquiry machines in public halls.

In the prior art, in the array substrate of the column-inversion double-gate display panel, each pixel unit in the same row of pixel units has the same luminous color, and two adjacent pixel units in the same row of pixel units have different luminous colors, and The same data line is electrically connected to the adjacent switching elements in the two columns of pixel units on both sides thereof. Since the same data line is electrically connected to pixel units with two different luminescent colors, when it is necessary to display a single color with high purity (such as red, green or blue), the data needs to be continuously changed within one frame. The data signal input on the line is several times to achieve the purpose of controlling the pixel units with the same luminous color and the color to be displayed to emit light normally, and the pixel units with a luminous color different from the color to be displayed to not emit light. Undoubtedly, during this process, the data signal of the data line changes frequently, and the charging or discharging time between the pixel electrode and the common electrode in each pixel unit is short, and each pixel unit cannot reach the expected operating voltage, resulting in the display panel displaying monochrome. The picture quality is poor.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

FIG. 1a is a schematic structural diagram of an array substrate in the prior art. Referring to FIG. 1a, the array substrate exemplarily includes: ten scanning lines 10 (respectively the first scanning line G1, the second scanning line G2, and the third scanning line G3) extending along the first direction (that is, the X-axis direction in the figure). , the fourth scanning line G4, the fifth scanning line G5, the sixth scanning line G6, the seventh scanning line G7, the eighth scanning line G8, the ninth scanning line G9 and the tenth scanning line G10), and five along the second direction The data lines 20 (respectively the first data line D1 , the second data line D2 , the third data line D3 , the fourth data line D4 and the fifth data line D5 ) extending (that is, the Y-axis direction in the figure). The ten scanning lines and the five data lines cross each other to define a plurality of pixel units, and the plurality of pixel units are arranged to form a matrix structure with 5 rows and 10 columns.

Two scan lines are arranged between two adjacent rows of pixel units. As shown in FIG. 1 a , two scanning lines are arranged between the first row of pixel units and the second row of pixel units, which are respectively the second scanning line G2 and the third scanning line G3 . Two columns of pixel units are arranged between two adjacent data lines. As shown in FIG. 1a, two columns of pixel units are arranged between the second data line D2 and the third data line D3. Each pixel unit in the same row of pixel units has the same luminescent color. As shown in FIG. 1 a , the light emitting color of the pixel units in the first column is red (R), and the light emitting colors of the pixel units in the second column are all green (G). Two adjacent pixel units in the same row of pixel units have different luminous colors, as shown in Figure 1a, from left to right, the luminous colors of each pixel unit in each row of pixel units are red (R), green (G), green (G), Blue (B), Red (R), Green (G), Blue (B), Red (R), Green (G), Blue (B). The same data line is electrically connected to any pixel unit in the two adjacent columns of pixel units. For example, the first data line D1 is electrically connected to any pixel unit in the first row of pixel units immediately adjacent to its left and to any pixel unit in a second row of pixel units immediately adjacent to its right. Two adjacent pixel units in each row of pixel units are respectively electrically connected to different scanning lines. For example, in the first row of pixel units, the first pixel unit from the left is electrically connected to the second scanning line G2, the second pixel unit from the left is electrically connected to the first scanning line G1, and the third pixel unit from the left is electrically connected to the second The scanning line G2 is electrically connected to, . . . . That is, the odd-numbered pixel units from the left are electrically connected to the second scanning line G2, and the even-numbered pixel units from the left are electrically connected to the first scanning line G1.

FIG. 1 b is a waveform diagram of a data signal transmitted on the first data line D1 when the display panel including the array substrate provided in FIG. 1 a displays red. Referring to Figure 1a and Figure 1b, when it is necessary to display red, within the working time of one frame, input scanning signals to each scanning line sequentially from top to bottom, so as to control the switch unit of each pixel unit electrically connected to it to turn on or closure. Since in FIG. 1 a , exemplarily, 10 scanning lines are included in total, and the time for transmitting scanning signals on each scanning line is 1/10 frame.

During the working time of the first 1/10 frame, a scanning signal is transmitted on the first scanning line G1, and the second pixel unit in the first row electrically connected to the first scanning line G1 is in an on state. At this time, referring to FIG. 1b, there is no data signal transmission on the first data line D1, so the second pixel unit in the first row does not emit light. During the working time of the second 1/10 frame, a scanning signal is transmitted on the second scanning line G2, and the first pixel unit in the first row electrically connected to the second scanning line G2 is in an on state. At this time, referring to FIG. 1 b , there is data signal transmission on the first data line D1 , so the first pixel unit in the first row emits light, and the color of the pixel unit is red. During the working time of the third 1/10 frame, the scanning signal is transmitted on the third scanning line G3, and the second pixel unit in the second row electrically connected to the third scanning line G3 is in an on state. At this time, referring to FIG. 1b, there is no data signal transmission on the first data line D1, so the second pixel unit in the second row does not emit light. ...During the working time of the tenth 1/10 frame, the scanning signal is transmitted on the tenth scanning line G10, and the first pixel unit in the fifth row electrically connected to the tenth scanning line G10 is in an on state. At this time, referring to FIG. 1b, there is data signal transmission on the first data line D1, so the first pixel unit in the tenth row emits light, and the light emission color of this pixel unit is red.

It can be seen that when it is necessary to facilitate the display panel including the array substrate in Figure 1a to display a single color with high purity (such as red, green or blue), within the working time of one frame, it is necessary to continuously change the data transmitted on the data line. the data signal several times to achieve the purpose of controlling the pixel units with the same luminous color and the color to be displayed to emit light normally, and the pixel units with a luminous color different from the color to be displayed to not emit light. Undoubtedly, in this process, the data signal of the data line changes frequently, and the charging or discharging time between the pixel electrode and the common electrode in each pixel unit is short, and each pixel unit cannot reach the expected working voltage, causing the display panel to display monochrome images. , the problem of poor picture quality.

In addition, it can also be seen from Figure 1a that during driving, when the first data line D1, the third data line D3, and the fifth data line D5 output positive polarity data signals, the second data line D2 and the fourth data line D4 output When the negative polarity data signal is received, the pixel units in the first column and the pixel unit in the second column electrically connected to the first data line D1 receive the data signals are positive data signals, and the third column electrically connected to the second data line D2 The data signals received by the pixel unit and the pixel unit in the fourth column are both negative polarity data signals, and the data signals received by the pixel units in the fifth column and the sixth column electrically connected to the third data line D3 are all positive polarity data. Signal,……. In this way, from the perspective of the polarity of the data signal, the adjacent four columns of pixel electrodes form a period, such as the first column of pixel units, the second column of pixel units, the third column of pixel units and the fourth column of pixel units form a period , the pixel units in the fifth column, the pixel units in the sixth column, the pixel units in the seventh column and the pixel units in the eighth column constitute a cycle. The pixel units with the same sequential status and the same polarity in two adjacent periods have a large span. As shown in Figure 1a, the first column of pixel units in the first period (ie, the first column of pixel units in Figure 1a) and the first column of pixel units in the second period (ie, the fifth column of pixel units in Figure 1a) are respectively The sequential positions in the periods are the same, they are the first row of pixel units in their respective periods, and the polarities of the data signals received during driving are the same. There are three columns of pixel units between these two columns of pixel units, and the span is very large. This will also reduce the picture quality of the display panel.

An embodiment of the present invention provides an array substrate, the array substrate includes: a plurality of scanning lines extending along a first direction; a plurality of data lines extending along a second direction; a plurality of scanning lines and a plurality of data lines intersect to define Multiple pixel units are arranged in a matrix, two scanning lines are set between two adjacent rows of pixel units, and one data line is set between two adjacent columns of pixel units. The same data line is only connected to one column The pixel units are electrically connected; each pixel unit in the same column of pixel units has the same light emitting color, and two adjacent pixel units in the same row of pixel units have different light emitting colors; each column of pixel units is electrically connected to the same adjacent data line , the same data line is only electrically connected to one column of pixel units; two adjacent pixel units in each row of pixel units are electrically connected to adjacent different scanning lines; one-to-one electrical correspondence with at least two columns of pixel units with the same luminous color At least two columns of data lines that are connected and output signals of the same polarity in the same frame are electrically connected.

In the embodiment of the present invention, by electrically connecting each column of pixel units to the same adjacent data line, and the same data line is electrically connected to only one column of pixel units, it solves the problem of the existing column-inverted double-gate display panel with high display purity. When monochrome, the data signal change frequency on the data line is too high, the charging or discharging time between the pixel electrode and the common electrode in each pixel unit is short, and each pixel unit cannot reach the expected working voltage, which leads to the problem of poor picture quality, which has been improved. The purpose of the picture quality when the display panel displays a monochrome picture.

Fig. 2a is a schematic structural diagram of an array substrate provided by an embodiment of the present invention. The embodiment of the present invention will be described in detail below with reference to FIG. 2a. Referring to FIG. 2a, the array substrate exemplarily includes: ten scanning lines extending along the first direction (the X-axis direction in the figure), which are respectively the first scanning line G1, the second scanning line G2, the third scanning line G3, the Four scanning lines G4, fifth scanning line G5, sixth scanning line G6, seventh scanning line G7, eighth scanning line G8, ninth scanning line G9 and tenth scanning line G10; twelve along the second direction (Fig. The data lines extending in the Y axis direction) are respectively the first data line D1, the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5, the sixth data line D6, the seventh data line The data line D7, the eighth data line D8, the ninth data line D9, the tenth data line D10, the eleventh data line D11 and the twelfth data line D12.

These scan lines and data lines intersect each other to define a plurality of pixel units (including a plurality of first pixel units R whose luminous color is red, a plurality of second pixel units G whose luminous color is green, and a plurality of luminous colors that are blue. The third pixel unit B), these pixel units are sorted to form a matrix structure with 5 rows and 12 columns.

Two scanning lines are arranged between two adjacent rows of pixel units, that is, two scanning lines are arranged between the first row of pixel units and the second row of pixel units from top to bottom, which are respectively the second scanning line G2 and the second row of pixel units. The third scanning line G3; two scanning lines are arranged between the second row of pixel units and the third row of pixel units, which are respectively the fourth scanning line G4 and the fifth scanning line G5; ...; the fourth row of pixel units and the third row of pixel units Two scan lines are arranged between the five rows of pixel units, namely the eighth scan line G8 and the ninth scan line G9 . In addition, a scanning line is provided on the side of the pixel units in the first row away from the pixel units in the second row, which is the first scanning line G1, and a scanning line is provided on the side of the pixel units in the fifth row away from the pixel units in the fourth row, It is the tenth scanning line G10.

A data line is set between two adjacent columns of pixel units, that is, a data line is set between the first column of pixel units and the second column of pixel units from left to right, which is the first data line D1; the second column A data line is set between the pixel unit and the pixel unit in the third column, which is the second data line D2; ...; a data line is set between the pixel unit in the eleventh column and the pixel unit in the twelfth column, which is the tenth A data line D11; a data line is provided on the side of the pixel unit in the twelfth column away from the pixel unit in the eleventh column, which is the twelfth data line D12.

Each pixel unit in the same column of pixel units has the same luminous color, that is, the first column of pixel units is the first pixel unit R, and its luminous color is red; the second column of pixel units is the second pixel unit G, and its luminous color is red. The colors are all green, the pixel units in the third column are all the third pixel unit B, and their luminous colors are all blue, the pixel units in the fourth column are all the first pixel units R, and their luminous colors are all red, ..., No. The pixel units in the twelve columns are all the third pixel unit B, and the light emitting colors thereof are all blue.

Two adjacent pixel units in the same row of pixel units have different luminous colors, that is, taking the first row of pixel units as an example, from left to right, the first pixel unit is the first pixel unit R, and its luminous color is red ; The second pixel unit is the second pixel unit G, its luminous color is green; the third pixel unit is the third pixel unit B, its luminous color is blue, and the fourth pixel unit is the first pixel unit R, Its luminous color is red, ..., the twelfth pixel unit is the third pixel unit B, and its luminous color is blue. Moreover, in each row of pixel units, from left to right, the order of the light emitting colors of each pixel unit is the same.

Each column of pixel units is electrically connected to the same adjacent data line, specifically, each pixel unit in each column of pixel units is electrically connected to the same adjacent data line on the left or right side thereof. Since in FIG. 2a, the left side of the pixel unit in the first row is not provided with a data line, for example, the pixel unit in the first row is set to be electrically connected to the first data line D1 on the right side, and the pixel unit in the second row is connected to the first data line D1 on the right side. The second data line D2 on the right side thereof is electrically connected to, . In this way, the same data line is only electrically connected to one column of pixel units.

Since the luminescent colors of the pixel units in the first column and the pixel units in the seventh column are both red, and during driving, within the working time of the same frame, the first data line D1 electrically connected to the pixel units in the first column and the pixel unit in the seventh The seventh data line D7 electrically connected to the column pixel units needs to output data signals of the same polarity, so the first data line D1 and the seventh data line D7 can be electrically connected. Since the luminous colors of the pixel units in the second column and the pixel units in the eighth column are both green, and when driving, the second data line D2 electrically connected to the pixel units in the second column and the pixel units in the eighth column and the The eighth data line D8 electrically connected to the pixel units needs to output data signals of the same polarity, so the second data line D2 and the eighth data line D8 can be electrically connected. ..., since the luminous colors of the pixel units in the sixth column and the pixel units in the twelfth column are both blue, and when driving, the sixth data line D6 electrically connected to the pixel units in the sixth column within the working time of the same frame The twelfth data line D12 electrically connected to the pixel unit in the twelfth column needs to output data signals of the same polarity, so the sixth data line D6 and the twelfth data line D12 can be electrically connected. That is, two data lines that are electrically connected are separated from each other by five data lines. For example, five data lines are separated between the first data line D1 and the seventh data line D7 electrically connected to each other, which are respectively the second data line D2, the third data line D3, the fourth data line D4, the fifth data line D5 and The sixth data line D6. Five data lines are separated between the second data line D2 and the eighth data line D8 electrically connected to each other. ..., five data lines are separated between the sixth data line D6 and the twelfth data line D12.

It should be noted that due to the limitation of the number of data lines, in Figure 2a, only two adjacent data lines that are electrically connected to two columns of pixel units with the same luminous color and output signals of the same polarity in the same frame during driving Wire connection. This is only a specific example of the present invention, rather than limiting the present invention. In specific design, it is possible to connect two or more columns of pixel units with the same luminescent color in one-to-one correspondence, and two or more columns that output signals of the same polarity in the same frame when driven are adjacent or non-adjacent The data line is electrically connected.

In use, for example, within the working time of a certain frame, when the first data line D1, the third data line D3, the fifth data line D5, the seventh data line D7, the ninth data line D9 and the tenth data line When a data line D11 needs to output a positive data signal, since the seventh data line D7 is electrically connected to the first data line D1, the ninth data line D9 is electrically connected to the third data line D3, and the eleventh data line D11 is electrically connected to the first data line D3. The five data lines D5 are electrically connected, and only need to transmit positive polarity data signals to the first data line D1 , the third data line D3 and the fifth data line D5 . Similarly, when the second data line D2, the fourth data line D4, the sixth data line D6, the eighth data line D8, the tenth data line D10 and the twelfth data line D12 need to output negative polarity data signals, only It is only necessary to transmit negative polarity data signals to the second data line D2 , the fourth data line D4 and the sixth data line D6 . In this way, the purpose of inputting data signals with opposite polarities to two adjacent data lines can be achieved.

Two adjacent pixel units in each row of pixel units are electrically connected to different adjacent scanning lines, specifically, the odd-numbered pixel unit in each row of pixel units is electrically connected to the scanning line above it, and the odd-numbered pixel unit in each row of pixel units is electrically connected to the scanning line above it. The even-numbered pixel units are electrically connected to the scanning lines below them; or the odd-numbered pixel units in each row of pixel units are electrically connected to the scanning lines below them, and the even-numbered pixel units in each row of pixel units are electrically connected to the scanning lines above them.

In FIG. 2 a , for example, the odd-numbered pixel units in each row of pixel units are electrically connected to the scan line below it, and the even-numbered pixel units in each row of pixel units are electrically connected to the scan line above it. Referring to Fig. 2a, the first row of pixel units is taken as an example for illustration. In this row of pixel units, the first pixel unit from the left is electrically connected to the second scanning line G2 located below it, and the second pixel unit is electrically connected to the second scanning line G2 located below it. The upper first scanning line G1 is electrically connected, the third pixel unit is electrically connected to the second scanning line G2 located below it, the fourth pixel unit is electrically connected to the first scanning line G1 located above it, ..., the first The eleventh pixel unit is electrically connected to the second scanning line G2 located below it, and the twelfth pixel unit is electrically connected to the first scanning line G1 located above it.

FIG. 2b is a comparison diagram of waveforms of data signals transmitted on the first data line D1 when the display panels respectively including the array substrates provided in FIG. 1a and FIG. 2a display red. Referring to Fig. 2a and Fig. 2b, when the display panel including the array substrate provided in Fig. 2a needs to display red, within the working time of one frame, input scanning signals to each scanning line sequentially from top to bottom, so as to control The switch units of the electrically connected pixel units are turned on or off. During this process, a constant voltage data signal is always input to the first data line D1.

Specifically, in FIG. 2 a , exemplarily, 10 scan lines are included in total, and the time for each scan line to transmit a scan signal is 1/10 frame. During the working time of the first 1/10 frame, the first scanning line G1 transmits scanning signals, but since none of the pixel units electrically connected to the first data line D1 is electrically connected to the first scanning line G1, the first data Line D1 transmits a constant voltage data signal which has no effect on the luminous color of the display panel. During the working time of the second 1/10 frame, the second scanning line G2 transmits scanning signals, and the first pixel unit counting from top to bottom in the first row of pixel units is electrically connected to the second scanning line G2, and the second scanning line G2 is electrically connected to the second scanning line G2. The pixel unit is in an on state, and receives a constant voltage data signal transmitted on the first data line D1, and emits red light. During the working time of the third 1/10 frame, the third scanning line G3 transmits scanning signals, but since none of the pixel units electrically connected to the first data line D1 is electrically connected to the third scanning line G3, the first The constant voltage data signal transmitted by the data line D1 has no effect on the luminous color of the display panel. ..., in the working time of the tenth 1/10 frame, the tenth scanning line G10 transmits scanning signals, and the fifth pixel unit counting from top to bottom in the first column of pixel units is electrically connected to the tenth scanning line G10 connected, the pixel unit is in the on state, and receives the constant voltage data signal transmitted on the first data line D1, and emits red light.

It can be seen that, when the display panel including the array substrate in FIG. The data lines electrically connected to the pixel units displaying the same color input a constant voltage data signal. It is not necessary to continuously change the data signal transmitted on the data line several times to control the normal light emission of the pixel units with the same color as the color to be displayed. The purpose of not emitting light is that the pixel units whose luminous color is different from the color to be displayed do not emit light. In this process, since the data signal of the data line is constant, the charging or discharging time between the pixel electrode and the common electrode in each pixel unit is very long, which is conducive to the operation of each pixel unit at the expected operating voltage, and then makes the display panel in the display When the monochrome screen is used, it has a good display effect.

In addition, in Fig. 2a, since the polarities of the data signals output by the first data line D1, the third data line D3, ..., the eleventh data line D11 are different from the polarities of the second data line D2, the fourth data line D2 and the fourth data line during driving. The polarities of the data signals output by the lines D4, ..., and the twelfth data line D12 are opposite. From the perspective of the polarity of the data signals alone, two adjacent columns of pixel electrodes form a period, such as the first column of pixel units and the second column of pixel electrodes. Two columns of pixel units form a period. The pixel units in the third column and the pixel units in the fourth column form a cycle. ..., the pixel units in the eleventh column and the pixel units in the twelfth column form a cycle. The first column of pixel units in the first period (ie, the first column of pixel units in Figure 2a) and the first column of pixel units in the second period (ie, the third column of pixel units in Figure 2a) have the same status in their respective periods , are the first row of pixel units in their respective periods, and the polarities of the data signals received during driving are the same. There is only one column of pixel units between the two columns of pixel units, and the span is very small. This is beneficial to further improving the picture quality of the display panel.

In Figure 2a, the luminescent colors of the pixel units include red, green and blue, and the three adjacent pixel units in each row of pixel units are a pixel unit group, and the pixel unit group is a minimum repeating unit; within the same pixel unit group Each pixel unit emits light in a different color. This is only a specific example of the present invention, rather than limiting the present invention. On this basis, the light emitting color of the pixel unit may also include white or yellow.

FIG. 3 is a schematic structural diagram of another array substrate provided by an embodiment of the present invention. Compared with FIG. 2 a , the light emitting colors of the array substrate in FIG. 3 include not only red, green and blue but also white. Referring to FIG. 3 , in the array substrate, the pixel units include a plurality of first pixel units R whose emission color is red, a plurality of second pixel units G whose emission color is green, and a plurality of third pixel units whose emission color is blue B and a plurality of fourth pixel units whose luminous color is white. The four adjacent pixel units in each row of the pixel units are a pixel unit group, and the pixel unit group is a minimum repeating unit; the luminescent colors of the pixel units in the same pixel unit group are different. Such setting is beneficial to increase the brightness of the display panel and achieve the effect of saving power consumption.

Further, the fourth pixel unit whose emission color is white in FIG. 3 can also be replaced by the fifth pixel unit whose emission color is yellow, and participate in the arrangement of the above pixel units. Such setting is also beneficial to increase the brightness of the display panel and achieve the effect of saving power consumption.

It should be pointed out that in the above technical solution, due to the addition of the fourth pixel unit whose light emission color is white or the fifth pixel unit whose light emission color is yellow, in order to satisfy the one-to-one correspondence with at least two rows of pixel units with the same light emission color The design requirements for the electrical connection of at least two columns of data lines that are connected and output signals of the same polarity in the same frame during driving, as shown in Figure 3, due to any pixel unit in the first column of pixel units and the fifth column of pixel units The luminescent colors are all red, and the first data line D1 electrically connected to the pixel unit in the first column and the fifth data line D5 electrically connected to the pixel unit in the fifth column output signals of the same polarity in the same frame during driving, which can Optionally, the first data line D1 and the fifth data line D5 are electrically connected. Similarly, the second data line D2 is electrically connected to the sixth data line D6, the third data line D3 is electrically connected to the seventh data line D7, the fourth data line D4 is electrically connected to the eighth data line D8, . . . . At this time, the two electrically connected data lines are separated from each other by three data lines. For example, there are three data lines between the first data line D1 and the fifth data line D5, which are respectively the second data line D2, the third data line D3 and the fifth data line D5. Similarly, three data lines are separated between the second data line D2 and the sixth data line D6. Three data lines are separated between the third data line D3 and the seventh data line D7. Three data lines are separated between the fourth data line D4 and the eighth data line D8.
