Description
Technical Field

Background
In a conventional liquid crystal display device, an Organic Light Emitting Diode (OLED) display device, each dot (pixel) is displayed with color by mixing light by a plurality of sub-pixels, for example, each pixel is composed of one each of a red sub-pixel, a green sub-pixel, and a blue sub-pixel (RGB mode). In order to improve the visual effect, increasingly higher requirements are made on the resolution (the number of pixels in a unit size) of the display device; this requires smaller and smaller sub-pixel sizes, but sub-pixel sizes cannot be scaled down indefinitely due to process limitations. In order to improve the display effect with a constant sub-pixel size, a Pentile mode display device has been proposed. In the Pentile mode display device, the number of sub-pixels (such as red sub-pixels and blue sub-pixels) of a part of colors is reduced by half; meanwhile, the display device virtually considers the sub-pixels with different colors to be in different layers, divides each layer into a plurality of sampling areas, does not overlap the division of the sampling areas of each layer, and then calculates the content to be displayed by each sub-pixel according to the area ratio of the sampling areas. Part of the sub-pixels in the Pentile mode display device are "common", thereby achieving a higher resolution than the actual resolution in visual effect.
However, in the transparent display technology, under the condition that the light transmittance is ensured to be good to the maximum extent, the arrangement of the common pixels (sub pixels) outside the hollowed area is combined, and an algorithm is used for performing color borrowing on each pixel, so that the requirement of high resolution of Panel is met under the condition that the number of sub pixels is small, and the technical problem to be solved is urgently needed.

Example 1:
as shown in fig. 1, the present embodiment provides a pixel array, including a pixel region and a hollow region; in the row direction and the column direction, the pixel areas and the excavated areas are alternately arranged; each pixel area is provided with a pixel repeating unit; a first pixel repeating unit 21 is arranged in a first row of pixel areas in any two adjacent rows of pixels, and a second pixel repeating unit 22 is arranged in the other row; the first pixel repeating unit 21 and the second pixel repeating unit 22 each include 2 first sub-pixels, 4 second sub-pixels, and 4 third sub-pixels; wherein, 2 first sub-pixels, 4 second sub-pixels and 4 third sub-pixels in the first pixel repeating unit 21 are arranged in 4 rows and 5 columns; the 2 first sub-pixels are respectively positioned on the 1 st row, the 3 rd column and the 4 th row, the 3 rd column; the 4 second sub-pixels are respectively positioned in the 2 nd row and the 2 nd column, the 2 nd row and the 3 rd column, the 3 rd row and the 2 nd column and the 3 rd row and the 3 rd column; the 4 third sub-pixels are respectively positioned on the 1 st row and the 1 st column, the 1 st row and the 5 th column, the 4 th row and the 1 st column and the 4 th row and the 5 th column; the 2 first sub-pixels, 4 second sub-pixels and 4 third sub-pixels in the first pixel repeating unit 22 are arranged in 5 rows and 4 columns; the 2 first sub-pixels are respectively positioned in the 1 st column of the 3 rd row and the 4 th column of the 3 rd row; the 4 second sub-pixels are respectively positioned in the 2 nd row and the 2 nd column, the 2 nd row and the 3 rd column, the 4 th row and the 2 nd column and the 4 th row and the 3 rd column; the 4 third sub-pixels are respectively positioned on the 1 st row and the 1 st column, the 1 st row and the 4 th column, the 5 th row and the 1 st column and the 5 th row and the 4 th column; each of the third sub-pixels is common in the first pixel repeating unit and the second pixel repeating unit.
As shown in fig. 1, in the present embodiment, the first sub-pixel is a red sub-pixel R, the second sub-pixel is a green sub-pixel G, and the third sub-pixel is a blue sub-pixel B. Of course, the first sub-pixel may be a green sub-pixel G or a blue sub-pixel B; the second sub-pixel is a red sub-pixel R or a blue sub-pixel G, and the third sub-pixel is a red sub-pixel R or a green sub-pixel, as long as the three sub-pixels are ensured to be different in color.
That is, each of the first and second pixel repeating units 21 and 22 includes 2 red, 4 green, and 4 blue sub-pixels; a first pixel repeating unit 21 is disposed in a first row of pixel regions of any two adjacent rows of pixels, and a second pixel repeating unit 22 is disposed in the other row. Each blue sub-pixel is shared in the first pixel repeating unit 21 and the second pixel repeating unit 22. It can be seen that the arrangement of the sub-pixels in the first pixel repeating unit 21 is 90 degrees different from the arrangement of the sub-pixels in the second pixel repeating unit 22 in the overall direction.
Specifically, taking the second pixel repeating unit 22 of the 2 nd row and the 2 nd column in fig. 1 as an example, the blue sub-pixel at the 1 st row and the 1 st column position in this second pixel repeating unit 22 is shared with the blue sub-pixel at the 5 th row and the 4 th column position in the first pixel repeating unit 21 of the 1 st row and the 2 nd column; the blue sub-pixel at the 1 st row, 5 th column position in this second pixel repeating unit 22 is shared with the blue sub-pixel at the 5 th row, 1 st column position in the 1 st row, 3 rd first pixel repeating unit 21; the blue sub-pixel at the 4 th row, 1 st column position in this second pixel repeating unit 22 is shared with the blue sub-pixel at the 1 st row, 4 th column position in the 3 rd row, 2 nd first pixel repeating unit 21; the blue sub-pixel at the 4 th row, 5 th column position in this second pixel repeating unit 22 is shared with the blue sub-pixel at the 1 st row, 1 st column position in the 3 rd row, 3 rd first pixel repeating unit 21. That is, each blue sub-pixel is applied to two pixel repeating units (in the first pixel repeating unit 21 and the second pixel repeating unit 22).
Preferably, one of any two adjacent rows of excavated areas is a first excavated area 11, and the other row is a second excavated area 12; the first excavated area 11 and the second excavated area 12 are positive directions, the extension line of the first edge of the first excavated area 11 is parallel to the row direction, and the extension line of the first edge of the second excavated area 12 is 45 degrees with the included angle of the row direction. Further, a distance L between two adjacent first excavated areas 11 in the row directionhA distance L between two adjacent first excavated areas 11 in the row directionvAre equal. In the row direction, a first pixel repeating unit 21 is arranged between two adjacent first excavated areas 11; in the column direction, the second pixel repeating unit 22 is disposed between two adjacent first dug-out areas 11. In summary, it can be understood that the distance L between two adjacent first excavated areas 11 in the row directionhA distance L between two adjacent first excavated areas 11 in the row directionvBoth equal to the width occupied by two theoretical pixel cells. Moreover, the distance between two adjacent first excavated area 11 and second excavated area 12 in the 45 degree direction is a gradually changing distance LxWherein the distance between the hanging corner of the first excavated area 11 and the second excavated area 12 is shortest.
Since the shape of the excavated area in this embodiment is square, the distance between two adjacent first excavated areas 11 in the row direction is equal to the distance between two adjacent first excavated areas 11 in the column direction, and the first excavated areas 11 and the second excavated areas 12 in two adjacent rows are arranged in a staggered manner, the distance between the upper row and the lower row is reasonably utilized, which is beneficial to increase the light-transmitting area; meanwhile, the structural deformation of an upper line and a lower line caused by too small space can be effectively avoided, the structural strength of the mask plate of the display panel in the etching process is improved, and the deformation caused by external force is reduced.
In the pixel array of this embodiment, if each of the first pixel repeating unit 21 and the second pixel repeating unit 22 is divided into four theoretical pixel units arranged in a matrix, the four theoretical pixel units are divided into a first theoretical pixel unit, a second theoretical pixel unit, a third theoretical pixel unit, and a fourth theoretical pixel unit; each theoretical pixel unit comprises theoretical sub-pixels of three colors of red, green and blue, wherein the blue theoretical sub-pixel in each theoretical pixel unit in each first pixel repeating unit 21 is shared with the blue theoretical sub-pixel in the respectively nearest theoretical pixel unit in the second pixel repeating unit 22; in the first pixel repeating unit 21, the red theoretical sub-pixel in the first theoretical pixel unit is shared with the red theoretical sub-pixel in the third theoretical pixel unit; the red theoretical sub-pixel in the second theoretical pixel unit is shared with the red theoretical sub-pixel in the fourth theoretical pixel unit; in the second pixel repeating unit 22, the red theoretical sub-pixel in the first theoretical pixel unit is shared with the red theoretical sub-pixel in the second theoretical pixel unit; and the red theoretical sub-pixel in the third theoretical pixel unit is shared with the red theoretical sub-pixel in the fourth theoretical pixel unit. Therefore, the pixel array of the present embodiment can realize high-resolution display with the same number of sub-pixels.
Example 2:
the present embodiment provides a driving method of a pixel array, wherein the pixel array may be the pixel array in embodiment 1. The driving method in this embodiment includes the steps of:
s1, dividing each first pixel repeating unit 21 and each second pixel repeating unit 22 in the pixel array into four theoretical pixel units which are arranged in a matrix, namely a first theoretical pixel unit, a second theoretical pixel unit, a third theoretical pixel unit and a fourth theoretical pixel unit; each theoretical pixel unit comprises a first theoretical sub-pixel, a second theoretical sub-pixel and a third theoretical sub-pixel (namely, the theoretical sub-pixels of three colors of red, green and blue shown in fig. 2), wherein in the row direction, the blue theoretical sub-pixel in each theoretical pixel unit in each first pixel repeating unit 21 is shared with the blue theoretical sub-pixel in the respectively nearest theoretical pixel unit in each second pixel repeating unit 22; in the first pixel repeating unit 21, the red theoretical sub-pixel in the first theoretical pixel unit is shared with the red theoretical sub-pixel in the third theoretical pixel unit; the red theoretical sub-pixel in the second theoretical pixel unit is shared with the red theoretical sub-pixel in the fourth theoretical pixel unit; in the second pixel repeating unit 22, the red theoretical sub-pixel in the first theoretical pixel unit is shared with the red theoretical sub-pixel in the second theoretical pixel unit; and the red theoretical sub-pixel in the third theoretical pixel unit is shared with the red theoretical sub-pixel in the fourth theoretical pixel unit.
And S2, calculating the theoretical brightness value of each theoretical sub-pixel in each theoretical pixel unit according to the image to be displayed.
And S3, calculating the actual brightness value of each sub-pixel in the pixel array according to a preset algorithm.
A specific implementation manner in this embodiment is given below. The row direction in the pixel array in this embodiment is perpendicular to the column direction, wherein one of any two adjacent rows of excavated areas is referred to as a first excavated area 11, the excavated area of the other row is referred to as a second excavated area 12, both the first excavated area 11 and the second excavated area 12 are in a positive direction, an extension line of a first edge of the first excavated area 11 is parallel to the row direction, and an included angle between the extension line of the first edge of the second excavated area 12 and the row direction is 45 degrees. In the row direction, a first pixel repeating unit 21 is arranged between two adjacent first excavated areas 11; in the column direction, the second pixel repeating unit 22 is disposed between two adjacent first dug-out areas 11. As shown in fig. 1 and 2, the driving method of the pixel array in this embodiment specifically includes:
step S1, a theoretical pixel unit dividing step.
Specifically, in the row direction, a method of dividing a theoretical pixel unit in a pixel repeating unit between two adjacent first hollow areas 11 is described. Take the first pixel repeating unit 21 of line 3, 2 as an example. The first pixel repeating unit 21 may be divided into a first theoretical pixel unit P52, a second theoretical pixel unit P53, a third theoretical pixel unit P62, and a fourth theoretical pixel unit P63. Similarly, the pixel repeating unit between two adjacent first excavated areas 11 in the row direction may be divided into theoretical pixel units according to the same method.
A method of dividing a theoretical pixel unit in a second pixel repeating unit 22 between two adjacent first dug-out areas 11 in a column direction. Take row 2, second pixel repeat unit 22 as an example. The second pixel repeating unit 22 can be divided into a first theoretical pixel unit P33, a second theoretical pixel unit P34, a third theoretical pixel unit P43 and a fourth theoretical pixel unit P44. Similarly, the pixel repeating unit between two adjacent first excavated areas 11 in the column direction may be divided into theoretical pixel units according to the same method.
In the row direction, the pixel sharing manner of the first pixel repeating unit 21 (the 2 nd pixel repeating unit in the 3 rd row) between two adjacent first hollow units is as follows: red subpixels in P52 and P62 are common; the red sub-pixel units in P53 and P63 are shared; blue subpixels in P52 and P42 are common; blue subpixels in P53 and P43 are common; blue subpixels in P62 and P72 are common; the blue subpixels in P63 and P73 are common.
The pixel sharing method of the second pixel repeating unit 22 (the 2 nd pixel repeating unit in the 2 nd row) located between two adjacent first hollow units in the column direction is as follows: red subpixels in P33 and P34 are common; red subpixels in P43 and P44 are common; blue subpixels in P33 and P23 are common; blue subpixels in P34 and P24 are common; blue subpixels in P43 and P53 are common; the blue subpixels in P44 and P54 are common. Step S2, calculating the brightness value of each sub-pixel in each theoretical pixel unit divided in step S1 according to the image to be displayed.
And step S3, calculating the actual brightness value of each sub-pixel in the pixel array by adopting a Rendering algorithm. Finally, corresponding signals are input for each sub-pixel according to the actual brightness value. Specifically, the red sub-pixel and the blue sub-pixel shared in each theoretical pixel unit are both twice the normal light emitting area. Of course, the light emitting area may also be variable with efficiency.
In summary, the driving method of the pixel array provided in this embodiment can achieve high-resolution pixel display with a small number of pixels. Therefore, the driving method of the pixel array of the embodiment has a better effect.
