In addition, the three-dimensional dimensions of length, width and height should be included in the actual fabrication.
Fig. 1 is a schematic structural diagram of an array substrate according to an embodiment of the present invention. As shown in fig. 1, the array substrate includes a plurality of repeating units 100 arranged in a matrix, and the plurality of repeating units 100 includes a plurality of first repeating units 110 and a plurality of second repeating units 120.
The odd-numbered rows of the matrix include a plurality of first repeating units 110 arranged in a first direction X, and the even-numbered rows include a plurality of second repeating units 120 arranged in the first direction X, wherein the first direction X is a row direction of the matrix. The first repeating unit 110 includes a first sub-pixel 101, a second sub-pixel 102, a third sub-pixel 103, and a second sub-pixel 102 sequentially arranged along a first direction X, and the second repeating unit 120 includes a third sub-pixel 103, a second sub-pixel 102, a first sub-pixel 101, and a second sub-pixel 102 sequentially arranged along the first direction X.
In the first repeating unit 110, the first sub-pixel 101 and the third sub-pixel 103 are inverted triangles, and the second sub-pixel 102 is a right triangle. In the second repeating unit 120, the first sub-pixel 101 and the third sub-pixel 103 are regular triangles, and the second sub-pixel 102 is an inverted triangle. The first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 emit light of different colors, wherein the first direction X is a row direction of the matrix.
With continued reference to fig. 1, the first repeating unit 110 and the second repeating unit 120 adjacent to each other in the matrix column direction Y form a minimal repeating unit 200 of the pixel array, the minimal repeating unit 200 includes two first sub-pixels 101, four second sub-pixels 102 and two third sub-pixels 103, each second sub-pixel 102 and the first sub-pixel 101 or the third sub-pixel 103 adjacently disposed on the left side form a physical pixel unit, and when performing image display, each physical pixel unit can form a display pixel unit by the third sub-pixel 103 or the first sub-pixel 101 adjacently disposed on the right side or the lower side, and each display pixel unit is used for displaying a picture of the image pixel unit at a corresponding position in the picture to be displayed.
Illustratively, the pixel array of FIG. 2 is used to display the image of FIG. 3. The image of fig. 3 comprises 16 image pixel units 300 of 4 rows and 4 columns, each image pixel unit 300 comprising a first sub-pixel 101, a second sub-pixel 102 and a third sub-pixel 103; the pixel array shown in fig. 2 includes 4 rows and 4 columns of 16 physical pixel units 400, and each physical pixel unit 400 includes a second sub-pixel 102 and a first sub-pixel 101 or a third sub-pixel 103. The color of the first sub-pixel 101 in the image pixel unit 300 is the same as that of the first sub-pixel 101 in the physical pixel unit 400, the color of the second sub-pixel 102 in the image pixel unit 300 is the same as that of the second sub-pixel 102 in the physical pixel unit 400, and the color of the third sub-pixel 103 in the image pixel unit 300 is the same as that of the third sub-pixel 103 in the physical pixel unit 400. When the image shown in fig. 3 is displayed by using the pixel array shown in fig. 2, each physical pixel unit 400 in the pixel array shown in fig. 2 uses its right-side adjacent sub-pixel to form a display pixel unit, which is used for displaying the picture of the image pixel unit 300 at the corresponding position in the image shown in fig. 3. For example, the first physical pixel unit 410 in the first row and the first column in the pixel array shown in fig. 2 includes a first pixel 101/1 and a second pixel 102/1, the first physical pixel unit 410 uses the first third sub-pixel 103/1 on the right side thereof to form a display pixel unit 500, which is used for displaying the picture of the first image pixel unit 310 in the first row and the first column in the image shown in fig. 3, specifically, the first gray-scale value of the second first sub-pixel 101/2 in the first image pixel unit 310 is obtained, and the first sub-pixel 101/1 in the pixel array shown in fig. 2 is lit by the first gray-scale value; acquiring a second gray-scale value of a second sub-pixel 102/2 in the first image pixel unit, and lighting a first second sub-pixel 102/1 in the pixel array in fig. 2 by using the second gray-scale value; and acquiring a third gray-scale value of the second third sub-pixel 103/2 in the first image pixel unit, and lighting the first third sub-pixel 103/1 in the pixel array shown in fig. 3 by using the third gray-scale value.
It can be understood that borrowing of sub-pixels is achieved by the above rendering method, and the borrowed sub-pixels are shared by the two display pixel units 500, so that the visual resolution of the display panel is improved.
In other embodiments of this embodiment, the physical pixel unit 400 in fig. 2 may further use the first sub-pixel 101 or the third sub-pixel 103 below the physical pixel unit, and for example, the first physical pixel unit 410 in fig. 2 may further use the third sub-pixel 103/3 in the first column and the second row to form a display pixel unit for displaying the picture of the first image pixel unit 310 in fig. 3. The first sub-pixel 101 or the third sub-pixel on the right side of the pixel is taken as an example for illustration and not limitation.
In addition, it should be further noted that the sub-pixels in the pixel array provided by this embodiment are triangular, an included angle between an end of each row of sub-pixels and the matrix row direction X is not 90 °, and for a circular display panel or the like, each step surface in a step-like edge can extend to a next step surface along a slope with a certain slope, so as to effectively improve the problem of saw teeth at the edge of the circular display panel.
In addition, since the sub-pixels in this embodiment are triangular, the second sub-pixel 102 can be complementary to the adjacent first sub-pixel 101 and the adjacent third sub-pixel 103 in the same row, so that the area of the spacing region between the adjacent sub-pixels is effectively reduced, the aperture opening ratio of the display panel is increased, and the pixel density of the display panel is favorably improved.
Fig. 4 is a schematic sectional view along the broken line AB in fig. 1. As shown in fig. 4, the sub-pixel includes a first electrode 321, a light-emitting functional layer 322, and a second electrode 323 sequentially stacked along a light emitting direction Z of the sub-pixel, and further includes a driving circuit, and in order to simplify the structure of the drawing, only a thin film transistor 330 in the driving circuit is shown in fig. 4, where the sub-pixels share the same second electrode 322. For example, the first electrode 321 may be an anode, and the second electrode 322 may be a cathode. With continued reference to fig. 4, two adjacent second sub-pixels 102, which are edge-oppositely disposed in the vertical direction Y of the first direction X, share the same light-emitting function layer 322.
With reference to fig. 1, the distance between the two second sub-pixels 102 whose edges are opposite in the Y direction is short, and no other structure is disposed between the two second sub-pixels 102, so that the two second sub-pixels share the same light-emitting functional layer 322, that is, the light-emitting functional layers corresponding to the two second sub-pixels 102 are formed by using the same opening of the mask. Due to the arrangement, the distance between the two second sub-pixels 102 with opposite edges in the Y direction is not limited by the process limit size of the bridge collapse between the adjacent openings of the corresponding mask any more, and the distance between the two second sub-pixels 102 can be smaller than the process limit size of the bridge collapse between the adjacent openings of the mask, so that the beneficial effects of further increasing the aperture opening ratio and improving the pixel density are achieved.
Alternatively, as shown in fig. 1, the shortest distance K between the opposite edges of any two adjacent sub-pixels is equal.
Wherein, the shortest distance K between the opposite edges of the adjacent sub-pixels is: and the distance between two nearest points on the opposite edges of any two adjacent sub-pixels. The shortest distance K between the opposite edges of the adjacent sub-pixels can be reasonably designed according to design requirements, and is generally limited to the situation that the problem of material color mixing between the adjacent sub-pixels cannot occur. The shortest distance K between the opposite edges of any two adjacent sub-pixels is equal, so that the color mixing uniformity of the light with different colors emitted by the sub-pixels can be improved, and the whole pixel array is arranged more regularly.
In this embodiment, the opposite edges of any two adjacent sub-pixels may be arranged in parallel, so as to further improve the effect of avoiding the problem of material color mixing between the adjacent sub-pixels.
Illustratively, the light emitting color of the first sub-pixel 101 is a first color, the light emitting color of the second sub-pixel 102 is a second color, and the light emitting color of the third sub-pixel 103 is a third color. The first color 101, the second color 102, and the third color 103 are any one of red, green, and blue, and are different from each other.
Since red, green, and blue are three primary colors of light, and red, green, and blue with different intensities can be mixed to obtain light of various colors, the emission colors of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are set to be any one of red, green, and blue, respectively, and are different from each other, so that the display panel can display various colors, and the display color of the display device can be enriched. It is understood that, in other embodiments of this embodiment, the first color, the second color, and the third color may also be other color combinations, which is not specifically limited in this embodiment.
Illustratively, the second color may be green.
It should be noted that, in the pixel rendering process, each display pixel unit includes a complete second sub-pixel, a part of the first sub-pixel and a part of the second sub-pixel, and because the sensitivity of human eyes to green is higher, the second color corresponding to the second sub-pixel is set to green, so that when the display screen is observed by human eyes, each display pixel unit is easily distinguished, the visual resolution is higher, and the visual screen is clearer.
Alternatively, the area of the blue sub-pixel may be larger than that of the red sub-pixel, and the area of the blue sub-pixel may be larger than that of the green sub-pixel.
On one hand, the lifetime of the blue sub-pixel is shorter than the lifetimes of the red sub-pixel and the green sub-pixel due to the characteristics of the forming material, and the current density of the blue sub-pixel can be reduced and the lifetime thereof can be improved by setting the area of the blue sub-pixel larger to avoid the lifetime of the blue sub-pixel from being reduced by the lifetime of the entire pixel array. On the other hand, the sensitivity of human eyes to blue is low, so that white light which can be recognized by human eyes is obtained by mixing light emitted by each sub-pixel, and the area of the blue sub-pixel corresponding to the blue and insensitive to the human eyes is large. In summary, the area of the blue sub-pixel is larger than the areas of the red sub-pixel and the green sub-pixel, so that the display life of the display panel can be prolonged, and the problem of color cast of the vision can be avoided.
With continued reference to fig. 1, the first subpixel 101 and the third subpixel 103 may both be isosceles triangles.
It should be noted that, compared with other triangles, the isosceles triangle shape is easier to obtain, so that the design difficulty in the above arrangement mode is lower, the sub-pixel rows have a certain height, the angles of the three corners of the opening in the mask used for forming the isosceles triangle sub-pixels are appropriate, the extremely small corners do not occur, and the difficulty in preparing the sub-pixels is reduced.
It is understood that fig. 1 only exemplifies that the shapes of the first sub-pixel 101 and the third sub-pixel 103 are isosceles triangles, and in other embodiments of the present embodiment, the shapes of the first sub-pixel 101 and the third sub-pixel 103 may be adjusted to be triangles with other shapes more practically, which is not limited in the present embodiment. It should be noted that, no matter how the shapes of the first sub-pixel 101 and the third sub-pixel 103 are changed, the shape of the second sub-pixel 102 is complementary to the shape of the first sub-pixel 101 and the third sub-pixel 103 adjacent to each other in the same row, so as to avoid space waste and facilitate the improvement of the aperture ratio of the display panel.
For high-resolution products, the pixel density of the display panel is increased, so the charging time of each row of pixels within one frame time is reduced, and if the charging time of the data signal to the sub-pixels is not enough, the current I when the sub-pixels emit light cannot reach the set value, which affects the display effect. Fig. 5 is a schematic structural diagram of another array substrate according to an embodiment of the present invention. As shown in fig. 5, the array substrate further includes a plurality of scan lines 201 and a plurality of data lines 202, each two adjacent rows of sub-pixels are electrically connected to one scan line 201, in the same column of sub-pixels, each sub-pixel in the odd sub-pixel row is electrically connected to one data line 202, and each sub-pixel in the even sub-pixel row is electrically connected to the other data line 202.
It should be noted that, with such an arrangement, each sub-pixel column is correspondingly connected to two data lines 202, and two sub-pixels in the same sub-pixel column are respectively connected to one data line 202, so that in an actual display process, when a gate of a previous row of pixels is turned on for charging, a next row of pixels can be pre-charged through a second data line, that is, the two data lines 202 can be used to realize fast and sufficient charging of each sub-pixel in the sub-pixel column, thereby avoiding the problem of insufficient sub-pixel charging amount caused by the single data line 202 charging the single row of sub-pixels, and being beneficial to improving the display effect of the high-frequency high-resolution display panel.
For example, with continued reference to fig. 5, the scanning line 201 electrically connected to every two rows of sub-pixels may be disposed between the two rows of sub-pixels, and the two data lines 202 electrically connected to each column of sub-pixels are disposed on two opposite sides of the column of sub-pixels, respectively.
It is understood that, on the premise of ensuring the electrical connection relationship between the sub-pixels and the corresponding scan lines 201 and the corresponding data lines 202, the positional relationship between the scan lines 201 and the data lines 202 and the sub-pixels is not limited to the case shown in fig. 5, and may be other reasonable cases, which is not specifically limited in this embodiment.
With continued reference to fig. 5, the edges of the first sub-pixel 101 and the third sub-pixel 103 arranged in the same row extending in the first direction X are located on the same straight line, which is parallel to the scanning line 201.
It should be noted that, this arrangement enables the scan lines 201 to be disposed between adjacent sub-pixel rows, thereby facilitating the electrical connection between each sub-pixel and the corresponding scan line 201. In addition, the arrangement mode can also improve the linearity of the display screen in the extending direction of the scanning line 201, so that the edge extending along the scanning line 201 in the display screen is clearer.
With reference to fig. 1, a distance between a target vertex D of the first sub-pixel 101 and a target vertex F of an adjacent third sub-pixel 103 in the same row in the first direction X is a, a distance between target vertices E of two second sub-pixels 102 that are disposed at an interval of one second sub-pixel 102 and are located in the same row in the first direction X is 2a, a distance between central lines l of two adjacent sub-pixel rows is a, the central lines l extend along the first direction X, where a is a preset pixel unit width, the sub-pixels include a first edge extending along the first direction X, and the target vertices are vertices opposite to the first edge.
It should be noted that the preset pixel unit is square, and the side length thereof is determined according to the actual area S of the display area of the display panel and the preset pixel density P, specifically, the side length of the preset pixel unit is M, and the area M of the preset pixel unit is recorded2And obtaining a specific value of the side length M of the preset pixel unit according to the S/P. It can be understood that the preset pixel unit is a pixel unit area obtained according to actual needs in a design stage of the display panel, each pixel unit area corresponds to one display pixel unit, and each display pixel unit is used for displaying picture content in one pixel unit in a picture to be displayed.
