The invention provides a pixel structure, which is positioned on a substrate, and the pixel structure comprises a plurality of pixel units, wherein the pixel unit can be understood as one pixel of a display device applying the pixel structure, and the display panel can be an electroluminescent display device (such as OLED, QLED and the like) and can also be a liquid crystal display device. Each pixel unit comprises a plurality of sub-pixels with three colors different from each other, and the sub-pixels with the three colors are respectively marked as a first sub-pixel, a second sub-pixel and a third sub-pixel. The plurality of sub-pixels in the pixel unit are arranged in a 2 × 4 mode, each row in the pixel unit arranged in the 2 × 4 mode comprises two first sub-pixels, and the color of the two adjacent sub-pixels is different; each column in the 2 × 4 arrangement of pixel units includes two sub-pixels, and the two sub-pixels are different in color. The sub-pixels in the same row of the 2 × 4 arrangement refer to sub-pixels located in the same straight line along the horizontal direction, the sub-pixels in the same column refer to sub-pixels located in the same order in adjacent rows, for example, numbers are provided for the sub-pixels in the pixel unit of the 2 × 4 arrangement, the sub-pixels in the first row are sequentially denoted as P1.1, P1.2, P1.3, and P1.4 along the row direction, the sub-pixels in the second row are sequentially denoted as P2.1, P2.2, P2.3, and P2.4 along the row direction, so that the sub-pixels represented by P1.1 and P2.1 are located in the same column, the sub-pixels represented by P1.2 and P2.2 are located in the same column, the sub-pixels represented by P1.3 and P2.3 are located in the same column, and the sub-pixels represented by P1.4 and P2.4 are located in the same column.

Therefore, the luminous surface of the first sub-pixel, the luminous surface of the second sub-pixel and the luminous surface of the third sub-pixel in the pixel unit are equal, so that the whole white balance of the pixel unit can be realized without adjusting the color resistance thicknesses of the first sub-pixel, the second sub-pixel and the third sub-pixel. In this embodiment, the heights of the first sub-pixel, the second sub-pixel and the third sub-pixel along the column direction may be the same, the width of the second sub-pixel along the row direction is equal to the width of the third sub-pixel along the row direction, and the width of the first sub-pixel along the row direction is half of the width of the second sub-pixel/the third sub-pixel along the row direction. Therefore, the number of the second sub-pixels and the number of the third sub-pixels are reduced, the number of the driving circuits for driving the second sub-pixels and the number of the driving circuits for driving the third sub-pixels are reduced, the design difficulty of the driving circuits can be reduced, and the aperture opening ratio of the pixel structure is improved.
Further, the first sub-pixel, the second sub-pixel and the third sub-pixel are preferably rectangular, and the width of the first sub-pixel along the row direction is one third of the height along the column direction; the width of the second sub-pixel and the width of the third sub-pixel along the row direction are two thirds of the height along the column direction, so that the sub-pixels in the pixel unit can be arranged side by side and the pixel unit is of a square structure, the space arrangement utilization rate can be improved, the mask design and generation difficulty can be reduced, the process stability and yield can be improved, and the pixel density and the display effect can be improved.
In order to further illustrate the display panel provided by the present invention, the present invention is further illustrated below with reference to two specific embodiments.
Example one
The embodiment provides a pixel structure, which includes a plurality of pixel units arranged in an array, each pixel unit includes 8 sub-pixels, each of the 8 sub-pixels includes four first sub-pixels, two second sub-pixels and two third sub-pixels, the two second sub-pixels and the two first sub-pixels are in the same row and are arranged alternately with each other, and the two third sub-pixels and the other two second sub-pixels are in adjacent rows and are arranged alternately with each other; the second sub-pixel and the third sub-pixel in the pixel unit are not in the same column. That is to say, the pixel unit is divided into two rows, one of the two rows includes two first sub-pixels and two second sub-pixels, the other row includes two first sub-pixels and two third sub-pixels, and the second sub-pixels and the third sub-pixels are not located in the same column, that is, the first sub-pixels located in the two rows are also not located in the same column, so that the distribution uniformity of the first sub-pixels, the second sub-pixels and the third sub-pixels can be improved.
The second sub-pixel is located on the right side of the first sub-pixel in the same row in the pixel unit, and the third sub-pixel is located on the left side of the first sub-pixel in the same row. In this embodiment, the pixel unit may be a pixel unit as shown in 21 in fig. 3, that is, a first row of the pixel unit includes two first sub-pixels (sub-pixel a in the figure) and two second sub-pixels (sub-pixel B in the figure), and the two first sub-pixels and the two second sub-pixels are located in the same row and are alternately arranged; the second row includes two first pixels and two third sub-pixels (sub-pixels C in the drawing) which are located in the same row and are alternately arranged, and the first sub-pixels are not located in the same column, and the second sub-pixels and the third sub-pixels are not located in the same column. That is to say, in the pixel unit 21, the first line includes a first sub-pixel, a second sub-pixel, a first sub-pixel, and a second sub-pixel from left to right, and the second line includes a third sub-pixel, a first sub-pixel, a third sub-pixel, and a first sub-pixel from left to right. In the pixel structure formed by the pixel units, the second sub-pixels are located on the same straight line along the row direction and the same straight line along the column direction, and the third sub-pixels are located on the same straight line along the row direction and the same straight line along the column direction, so that the arrangement regularity of the second sub-pixels and the third sub-pixels is improved.
In this embodiment, the first sub-pixel, the second sub-pixel, and the third sub-pixel are respectively selected from one of red, green, and blue. And preferably, the first sub-pixel is preferably green, and the second sub-pixel and the third sub-pixel are respectively selected from one of red and blue. Thus, the arrangement structure of the pixel units 21 arranged 2 × 4 is selected from the following arrangement: (1) the first row is G, R, G, R from left to right and the second row is B, G, B, G from left to right; (2) the first row is G, B, G, B from left to right and the second row is R, G, R, G from left to right. The number ratio of the green sub-pixels to the red sub-pixels to the blue sub-pixels is 2:1: 1. Therefore, by combining the two red sub-pixels and the two blue sub-pixels and adopting the 2 x 4 arrangement mode, on one hand, the spatial sampling of each primary color light can be homogenized, and the resolution of the display screen can be effectively improved. On the other hand, the number of driving circuits, that is, the number of TFTs and the frame lines of the sub-pixels can be reduced, thereby improving the transmittance and the average aperture ratio of the pixel structure.
Further, in the pixel structure shown in fig. 3, the arrangement of the first sub-pixels is uniform, and there are six first sub-pixels nearest to any one of the first sub-pixels except the first sub-pixel located at the edge. For example, in the first sub-pixel 201 shown in fig. 3, the six nearest first sub-pixels are the first sub-pixel 202, the first sub-pixel 203, the first sub-pixel 204, the first sub-pixel 205, the first sub-pixel 206 and the first sub-pixel 207, respectively; the six first sub-pixels are uniformly distributed around the first sub-pixel 201 at the central position, and the connection lines of the six first sub-pixels far away from the vertex of the first sub-pixel 201 (or the central connection lines of the six first sub-pixels, not shown) can form a structure similar to a regular hexagon, so that the first sub-pixels in the display panel are very uniformly distributed and tend to be isotropic in spatial arrangement, and the spatial sampling of the first sub-pixels is more uniform. The first sub-pixels are green sub-pixels, and green is more sensitive to human eyes in spatial resolution than blue and red, so that the green sub-pixels tend to be isotropic in spatial arrangement in the arrangement mode, spatial sampling of the green pixels is more uniform, and the resolution is improved. In addition, the second sub-pixel and the third sub-pixel have small contribution to brightness, the spatial arrangement rule of the second sub-pixel and the third sub-pixel cannot cause distortion when an image is observed, the influence on the resolution cannot cause visual attention, and the higher resolution of the display panel is ensured.
In order to improve the white balance of the display panel, in a further specific embodiment, the first sub-pixel, the second sub-pixel and the third sub-pixel occupy the same area in the pixel unit. That is to say, in the pixel unit, the area sum of all the first sub-pixels, the area sum of all the second sub-pixels and the area sum of the third sub-pixels are equal, so that the areas of the red sub-pixels, the green sub-pixels and the blue sub-pixels are the same as each other on the whole, the pixel unit can reach white balance without adjusting the thickness of color resistance, the light transmittance of the display screen can be effectively improved, and the production cost of the display screen is reduced. In this embodiment, the widths of the second sub-pixel and the third sub-pixel along the row direction are equal, and the width of the first sub-pixel along the row direction is half of the width of the second sub-pixel/the third sub-pixel along the row direction. Therefore, the widths of the second sub-pixel and the third sub-pixel can be increased, thereby reducing the manufacturing difficulty and improving the color mixing phenomenon of the pixel structure.
In a preferred embodiment of this embodiment, the aspect ratio of the first sub-pixel is 1:3, and the aspect ratios of the second sub-pixel and the third sub-pixel are both 2: 3. On one hand, the areas of all the first sub-pixels, all the second sub-pixels and all the third sub-pixels are equal, and the areas of the second sub-pixels and the third sub-pixels are twice of the areas of the first sub-pixels, so that the number of the second sub-pixels and the third sub-pixels can be reduced, the number of the driving units of the second sub-pixels and the third sub-pixels and the number of the frames of the second sub-pixels and the third sub-pixels are reduced, the number of the driving units of the display panel is reduced by one third, and the transmittance of the display panel is improved.
Furthermore, in the modified embodiment of the present embodiment, as described in the embodiment shown in fig. 3, it is not limited that only the pixel units 21 can be repeatedly stacked to form the pixel structure, and the pixel structure may be formed in a continuous 2 × 4 sub-pixel array arbitrarily selected from fig. 3, such as the pixel unit 22 selected from fig. 3. The second sub-pixel is located at the left side of the first sub-pixel in the same row in the pixel unit 22, and the third sub-pixel is located at the right side of the first sub-pixel in the same row. That is to say, the arrangement structure of the pixel units may be that the first row sequentially includes the second sub-pixel, the first sub-pixel, the second sub-pixel, and the first pixel from left to right, and the second row sequentially includes the first sub-pixel, the third sub-pixel, the first sub-pixel, and the third sub-pixel from left to right. When the first sub-pixel is a green sub-pixel, and the second sub-pixel and the third sub-pixel are respectively one of a red sub-pixel and a blue sub-pixel, the arrangement structure of the pixel unit is selected from the following arrangement modes: (1) the first row is R, G, R, G from left to right and the second row is G, B, G, B from left to right; (2) the first row is B, G, B, G from left to right and the second row is G, R, G, R from left to right. The size and shape of the first sub-pixel, the second sub-pixel and the third sub-pixel are the same as those of the above embodiment, that is, the width of the second sub-pixel and the width of the third sub-pixel along the row direction are the same, and the width of the first sub-pixel along the row direction is half of the width of the second sub-pixel/the third sub-pixel along the row direction.
Example two
The present embodiment provides a pixel structure, which is the same as the pixel structure disclosed in the first embodiment, and is formed by repeatedly stacking a plurality of pixel units, and the number and area of the first sub-pixel, the second sub-pixel, and the third sub-pixel included in the pixel units are the same, but the difference is that the arrangement manner of the first sub-pixel, the second sub-pixel, and the sub-pixels is different. Only the differences are explained here, and the same parts are not described in detail.
In this embodiment, the pixel unit includes four first sub-pixels, two second sub-pixels and two third sub-pixels, wherein one of the second sub-pixels and one of the third sub-pixels are located in the same row as the two first sub-pixels and are alternately arranged with the first sub-pixels, and the other of the second sub-pixels and the other of the third sub-pixels are located in an adjacent row with the other two first sub-pixels and are alternately arranged with the first sub-pixels; the first sub-pixels are not in the same column along the column direction.
In two rows adjacent to each other in the column direction of the pixel unit, the second sub-pixel is located on the left side of the third sub-pixel in one row, and the second sub-pixel and the third sub-pixel are both located on the left side/right side of the adjacent first sub-pixel, and the second sub-pixel is located on the right side of the third sub-pixel in the other row, and the second sub-pixel and the third sub-pixel are both located on the right side/left side of the adjacent first sub-pixel. In this way, the second sub-pixels and the third sub-pixels in adjacent rows in the pixel unit are not located in the same column, that is, in the pixel structure formed by the pixel unit, the two second sub-pixels located in the same column are not located in the same straight line, and the two third sub-pixels located in the same column are also not located in the same straight line. In addition, the second sub-pixel and the third sub-pixel arranged in the row direction are located on the same straight line. In this embodiment, the definition of the sub-pixels in the same column is the same as that in the first embodiment, and detailed description thereof is omitted.
For example, as shown in fig. 4, in the pixel unit 31, the first row includes two first sub-pixels (sub-pixel a in the figure), one second sub-pixel (sub-pixel B in the figure), and one third sub-pixel (sub-pixel C in the figure), the second sub-pixel and the third sub-pixel are not adjacent; the second row comprises two first sub-pixels, a second sub-pixel and a third sub-pixel, and the second sub-pixel and the third sub-pixel are not adjacent. Of course, in the pixel unit, two sub-pixels included in each column are different. That is to say, the arrangement structure of the pixel units may be a first sub-pixel, a second sub-pixel, a first sub-pixel, and a third sub-pixel, and the second row includes the third sub-pixel, the first sub-pixel, the second sub-pixel, and the first sub-pixel from left to right. Accordingly, when the first sub-pixel is a green sub-pixel, and the second sub-pixel and the third sub-pixel are one of red and blue, the arrangement structure of the pixel units of the 2 × 4 arrangement may be selected from the following arrangement: (1) the first row is G, R, G, B from left to right and the second row is B, G, R, G from left to right; (2) the first row is G, B, G, R from left to right and the second row is R, G, B, G from left to right.
In addition, in the modified embodiment of the present embodiment, the pixel units 31 may also be arranged in the manner of the pixel units 32 or the pixel units 33 selected from fig. 4. That is, the arrangement structure of the 2 × 4 arranged pixel units is selected from the following arrangement modes: (1) the first line is respectively a first sub-pixel, a third sub-pixel, a first sub-pixel and a second sub-pixel from left to right, and the second line is respectively a second sub-pixel, a first sub-pixel, a third sub-pixel and a first sub-pixel from left to right; (2) the first line is respectively a third sub-pixel, a first sub-pixel, a second sub-pixel and a first sub-pixel from left to right, and the second line is respectively a first sub-pixel, a third sub-pixel, a first sub-pixel and a second sub-pixel from left to right. Accordingly, when the first sub-pixel is a green sub-pixel, and the second sub-pixel and the third sub-pixel are one of red and blue, the arrangement structure of the pixel units of the 2 × 4 arrangement may be selected from the following arrangement: (1) g, B, G, R is sequentially arranged from left to right in the first row, R, G, B, G is sequentially arranged from left to right in the second row, (2) G, R, G, B is sequentially arranged from left to right in the first row, B, G, R, G is sequentially arranged from left to right in the second row, (3) B, G, R, G is sequentially arranged from left to right in the first row, G, B, G, R is sequentially arranged from left to right in the second row, (4) R, G, B, G is sequentially arranged from left to right in the first row, and G, R, G, B is sequentially arranged from left to right in the second row.
