Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the related art, in the inorganic micro light emitting diode display, since the size of the inorganic micro light emitting diode is small, the size of the inorganic micro light emitting diode is relatively small in the pixel unit composed of three inorganic micro light emitting diodes. This results in a small proportion of the inorganic micro light emitting diode emitting light and a large black area not emitting light in one pixel unit. In a display panel formed by pixel units, black areas which do not emit light between different rows and between different columns extend in a wider width, which may cause black stripes on a screen displayed on the display panel. In addition, in the pixel arrangement manner in the related art, the same row or column is generally formed with the same color, which causes a problem of visual character deviation when the display panel displays a picture. In order to improve the above technical problems, the present application may provide the following embodiments.

The embodiment of the application provides a display device. The display device includes a main body, a processor and a micro light emitting diode display panel (hereinafter, referred to as a display panel), the processor and the display panel are mounted to the main body, and the processor is connected with the display panel. The processor may be any device having computing or data processing capabilities, and is not particularly limited. The display panel may be described as follows.

Referring to fig. 1, an embodiment of the present application provides a micro light emitting diode display panel. The display panel has a display area 10 (see any of fig. 8 to 11). A plurality of pixel units 11 are arrayed in each display area 10, and each pixel unit 11 can be used for displaying different colors. Each pixel cell 11 is constituted by a 6 by 6 virtual grid (see the grid constituted by the broken lines in fig. 1). The pixel unit 11 separates a first quadrant 21, a second quadrant 22, a third quadrant 23, and a fourth quadrant 24 respectively composed of 3 by 3 virtual grids with the center point of the virtual grid as the origin and the grid lines as the coordinate axes. Each of the first to fourth quadrants 21 to 24 includes three subpixels 111 for displaying different colors. For example, the three sub-pixels 111 are respectively a red sub-pixel, a green sub-pixel, and a blue sub-pixel, that is, three primary colors of light. The light emission of the three sub-pixels 111 in each quadrant can be matched with each other by the driving signal, thereby displaying different colors.

Wherein diagonal lines in the first quadrant 21 to the fourth quadrant 24 can constitute a virtual quadrangle. Each of the first to fourth quadrants 21 to 24 includes two diagonal lines, but the diagonal lines can be connected to each other to constitute a virtual quadrangle only as a diagonal line passing through no origin in each quadrant, and in particular, reference may be made to the virtual quadrangle in fig. 1. The three sub-pixels 111 of each of the first to fourth quadrants 21 to 24 are respectively located in a grid corresponding to a diagonal line. The position of the sub-pixel 111 in the grid is not particularly limited. In one pixel unit 11, three sub-pixels 111 for displaying different colors are provided within each quadrant, and the three sub-pixels 111 in each quadrant are located in a grid corresponding to a diagonal line in the quadrant. And the diagonal lines corresponding to the sub-pixels 111 in the four quadrants can constitute a virtual quadrilateral. In this way, the spacing between different rows and different columns of the display panel can be made smaller. Therefore, gaps between different rows and different columns of the display panel are regular, black stripes in a picture displayed by the display panel can be reduced, and the display quality of the display panel is improved.

Further, two sub-pixels 111 located in the same row of the virtual grid in each pixel unit 11 are different in color from each other, and two sub-pixels 111 located in the same column are different in color from each other. In each pixel unit 11, two sub-pixels 111 of the same row and the same column display colors different from each other. Thus, the same row and the same column in the display panel have different colors, the problem of visual character deviation can be reduced, and the display quality of the display panel is further improved.

The following description of the specific embodiment of the pixel unit 11 will be given for convenience of description, in which the color abbreviations are used to represent the sub-pixels 111 of different colors, the red sub-pixel is specifically represented by R, the green sub-pixel is represented by G, and the blue sub-pixel is represented by B:

for example, in fig. 2, in the positive direction of the X-axis, the colors of the three sub-pixels 111 of the first quadrant 21 of the pixel unit 11 are RBG in order. The three sub-pixels 111 of the second quadrant 22 are in turn RGB in color. The three sub-pixels 111 of the third quadrant 23 are in turn GBR in color. The three sub-pixels 111 of the fourth quadrant 24 are in turn GRB in color.

For example, in fig. 3, in the positive direction of the X-axis, the colors of the three sub-pixels 111 in the first quadrant 21 of the pixel unit 11 are BGR in order. The three sub-pixels 111 of the second quadrant 22 are in turn BRG in color. The three sub-pixels 111 of the third quadrant 23 are in turn RGB in color. The three sub-pixels 111 of the fourth quadrant 24 are in turn RBG in color.

For example, in fig. 4, in the positive direction of the X-axis, the color of the three sub-pixels 111 of the first quadrant 21 of the pixel unit 11 is GRB in order. The three sub-pixels 111 of the second quadrant 22 are in turn GBR in color. The three sub-pixels 111 of the third quadrant 23 are in turn BRG in color. The three sub-pixels 111 of the fourth quadrant 24 are sequentially BGR in color.

For example, in fig. 5, in the positive direction of the X-axis, the colors of the three sub-pixels 111 of the first quadrant 21 of the pixel unit 11 are RBG in order. The three sub-pixels 111 of the second quadrant 22 are in turn BRG in color. The three sub-pixels 111 of the third quadrant 23 are in turn RGB in color. The three sub-pixels 111 of the fourth quadrant 24 are in turn GRB in color.

For example, in fig. 6, in the positive direction of the X-axis, the color of the three sub-pixels 111 of the first quadrant 21 of the pixel unit 11 is GRB in order. The three sub-pixels 111 of the second quadrant 22 are in turn RGB in color. The three sub-pixels 111 of the third quadrant 23 are in turn GBR in color. The three sub-pixels 111 of the fourth quadrant 24 are sequentially BGR in color.

For example, in fig. 7, in the positive direction of the X-axis, the colors of the three sub-pixels 111 in the first quadrant 21 of the pixel unit 11 are BGR in order. The three sub-pixels 111 of the second quadrant 22 are in turn GBR in color. The three sub-pixels 111 of the third quadrant 23 are in turn BRG in color. The three sub-pixels 111 of the fourth quadrant 24 are in turn RGB in color.

In the above embodiment of the pixel unit 11, two sub-pixels 111 in the same row and two sub-pixels 111 in the same column are all satisfied for displaying different colors.

In one embodiment, the pixel units 11 of the same display area 10 have the same pixel arrangement. Specifically, the display panel may be formed of a plurality of display areas 10, and different display areas 10 may have the same arrangement of the pixel units 11 or may have different arrangements of the pixel units 11, which is not particularly limited herein. In the display area 10, a plurality of pixel units 11 are arranged, and the arrangement of the sub-pixels 111 in the pixel units 11 may be any of the embodiments of the pixel units 11 described above. In the same display area 10, the arrangement of the subpixels 111 in each pixel unit 11 is the same. In other words, the same display area 10 may be configured such that one of the embodiments of the pixel unit 11 described above is arranged as a repeating unit. Therefore, the arrangement of the pixel units 11 in the display area 10 is regular, and the production and the manufacture of the display panel can be facilitated.

In an embodiment, the pixel arrangements of the pixel units 11 of the same display area 10 are not identical. Wherein any adjacent three sub-pixels 111 located in the same row and/or column within the display area 10 are used to display colors different from each other. By this arrangement, three colors can be provided in the same row and the same column in the display area 10, and thus, the problem of visual character deviation can be further reduced.

Referring to fig. 8 to 11, the pixel units 11 of the same display area 10 include a first pixel unit, a second pixel unit, and a third pixel unit having different pixel arrangements. The first pixel unit, the second pixel unit, and the third pixel unit may be any three of the above-described embodiments of the pixel unit 11. The display area 10 is formed by 3 pixel units 11, wherein the three pixel units 11 of each row are a first pixel unit, a second pixel unit, and a third pixel unit, respectively, and the three pixel units 11 of each column are also a first pixel unit, a second pixel unit, and a third pixel unit, respectively. In other words, the first, second and third pixel units occur only once in each row and each column of the display area 10. By the arrangement, the first pixel units, the second pixel units and the third pixel units which are distributed by different pixels can be uniformly distributed in the display area 10, and uniformity of display is improved. And the display area 10 thus arranged can satisfy any adjacent three sub-pixels 111 of the same row and/or the same column can display colors different from each other. Taking fig. 8 as an example, the three pixel units 11 in the first row are sequentially configured by the pixel units 11 shown in fig. 2, 3 and 4, respectively. The pixel unit 11 shown in fig. 2 is a first pixel unit, the pixel unit 11 shown in fig. 3 is a second pixel unit, and the pixel unit 11 shown in fig. 4 is a third pixel unit. Thus, in fig. 8, the first row is arranged with the first pixel unit, the second pixel unit, and the third pixel unit in order. The second row is arranged with a second pixel unit, a third pixel unit and a first pixel unit in sequence. The third row is arranged with a third pixel unit, a first pixel unit and a second pixel unit in sequence. The first column is arranged with a first pixel unit, a second pixel unit and a third pixel unit in sequence. The second column is arranged with a second pixel unit, a third pixel unit and a first pixel unit in sequence. The third column is arranged with a third pixel unit, a first pixel unit and a second pixel unit in sequence.

In one embodiment. In the same row or the same column of the display area 10, the colors of any adjacent three sub-pixels 111 are arranged in red, green, and blue or green, blue, and red or one of blue, red, and green. For example, in fig. 8, the display area 10 shown in fig. 8 is constituted by the pixel units 11 shown in fig. 2, 3, and 4 being arranged as the first pixel unit, the second pixel unit, and the third pixel unit, respectively, in the manner described above. In the first behavior example, the color arrangement is BRGBRG. Taking the first column as an example, the color arrangement is RGBRGB. For example, fig. 9, the display area 10 shown in fig. 9 is constituted by the pixel units 11 shown in fig. 5, 6, and 7 as the first pixel unit, the second pixel unit, and the third pixel unit, respectively. Taking the first column as an example, the color arrangement is BRGBRG. By the arrangement, the sub-pixels 111 with three colors in the same row or the same column can be sequentially arranged, so that the sub-pixels 111 with the same display color in the same row or the same column are reduced from being close to each other or densely distributed, and the light emitting uniformity of the display area 10 is improved.

In another embodiment. In the same row or column of the display area 10, the color arrangement of any adjacent three sub-pixels 111 is red, blue, and green or blue, green and red or one of green, red, and blue. For example, fig. 9, the display area 10 shown in fig. 9 is constituted by the pixel units 11 shown in fig. 5, 6, and 7 as the first pixel unit, the second pixel unit, and the third pixel unit, respectively. In the first behavior example, the color arrangement is GRBGRB. For example, the display area 10 shown in fig. 10 may be obtained by mirror-inversion of the display area 10 shown in fig. 8 or 9. In the first behavior example, the colors are arranged as RBGRBG. Taking the first column as an example, the color arrangement is GRBGRB. By the arrangement, the sub-pixels 111 with three colors in the same row or the same column can be sequentially arranged, so that the sub-pixels 111 with the same display color in the same row or the same column are reduced from being close to each other or densely distributed, and the light emitting uniformity of the display area 10 is improved.

In an embodiment, the display panel is formed by arranging a plurality of display areas 10 in an array, wherein the pixel units 11 of two adjacent display areas 10 are arranged differently.

Specifically, for example, in the display areas 10 arranged in the same arrangement direction, that is, in the display areas 10 arranged in the same row or in the display areas 10 arranged in the same column, adjacent display areas 10 are arranged in mirror symmetry. For example, referring to fig. 8 and 9, the display area 10 shown in fig. 8 and 9 has a mirror-symmetrical relationship. The display panel may have the arrangement of the display areas 10 shown in fig. 8 and 9.

In another embodiment, the relationship between two adjacent display areas 10 satisfies that one display area 10 has the same pixel arrangement as the other display area 10 after being rotated 90 degrees clockwise or counterclockwise. For example, fig. 8 and 11, the display area 10 shown in fig. 11 can be formed by rotating the display area 10 shown in fig. 8 counterclockwise by 90 degrees. The display panel may have the arrangement of the display areas 10 shown in fig. 8 and 11. In other embodiments, the relationship between two adjacent display areas 10 may be that one display area 10 has the same pixel arrangement as the other display area 10 after rotating 180 degrees clockwise or anticlockwise.

By arranging the adjacent two display areas 10 by adopting different pixel units 11, the display areas 10 with different luminous effects can be complemented, and the luminous uniformity of the display panel is improved. And, the adjacent two display areas 10 can be obtained by mirror symmetry or rotation. Therefore, the production requirements of different display areas 10 can be met through overturning or rotating modes by the aid of process equipment such as masks in the production process of the display panel, production cost can be reduced, and the display panel is convenient to manufacture.

The foregoing is only examples of the present application, and is not intended to limit the scope of the patent application, and all equivalent structures or equivalent processes using the descriptions and the contents of the present application or other related technical fields are included in the scope of the patent application.
