The invention relates to a display panel, in particular to a pixel arrangement of a display panel. The invention also relates to a display device including the display panel and a method of the pixel arrangement.

Generally speaking, display devices can be divided into display panels using red, green and blue (RGB) pixel arrangements and display devices using red, green, blue and white (RGBW) pixel arrangements; many improvements have been made to the above display panels. Technical proposals, such as Chinese Patent Publication No. 1774664, US Patent Publication No. 7148901, and other US Patent Publication No. 20070002083.

However, as far as display devices are concerned, the power consumption of backlight modules accounts for a large part; compared with display devices using RGB pixel arrays, display devices using RGBW pixel arrays can provide more power at the same backlight brightness. The high-contrast display effect can significantly reduce the power consumption of the display device.

In order to facilitate understanding, the same elements in the following embodiments are described with the same symbols.

Please refer to FIG. 2, which is a first schematic diagram of a first embodiment of a display panel of the present invention. The display panel 1 may include a plurality of pixels 11, and each pixel 11 may include a first sub-pixel 111A and a second sub-pixel 111B. , The third sub-pixel 111C, and the fourth sub-pixel 111D; the first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D are arranged along a horizontal direction H. In this embodiment, the first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D may be sub-pixels of different colors, for example, a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Sub-pixels and white sub-pixels, and the shape can be rectangular. In this embodiment, the colors of the first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D in each pixel 11 are arranged in the same order (for example, all are red, green, blue, and white); However, in another embodiment, the colors of the first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D in each pixel 11 may also be arranged in different orders.

The first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D may be arranged in a staggered manner to form the pixel 11. Among them, the second sub-pixel 111B may be adjacent to the first sub-pixel 111A and may partially overlap the first sub-pixel in the horizontal direction H; the third sub-pixel 111C may be adjacent to the second sub-pixel 111B and may be horizontal.

One sub-pixel 111A is partially overlapped and can be completely overlapped with the second sub-pixel 111B.

In addition, in the two adjacent pixels in the horizontal direction H (that is, two pixels in the same row in the adjacent row), the fourth sub-pixel 111D of one pixel completely coincides with the first sub-pixel 111A of the other pixel, Therefore, in the first embodiment of the display panel, the pixels 11 in the same row can be formed in the same staggered arrangement, and the staggered arrangement of the pixels 11 in this row can be staggered with the pixels 11 in adjacent rows. The arrangement is reversed. As shown in FIG. 2, for each pixel 11 in the first row, the upper half of the second sub-pixel 111B may coincide with the lower half of the first sub-pixel 111A in the horizontal direction H, and the third sub-pixel 111C The lower half may coincide with the upper half of the second sub-pixel 111B in the horizontal direction H, and the upper half of the fourth sub-pixel 111D may coincide with the lower half of the third sub-pixel 111C in the horizontal direction H.

In the horizontal direction H, it may overlap the lower half of the second sub-pixel 111B, and in the horizontal direction H, the lower half of the fourth sub-pixel 111D may overlap the upper half of the third sub-pixel 111C.

Since the display panel 1 of this embodiment has a special design, each pixel 11 and the adjacent pixel 11 'There may be partial overlap, so it can show continuous lines when displaying graphics such as diagonal lines or curves, so it can produce better visual effects.

As shown in FIG. 3, when the display device D uses the display panel 1 of this embodiment to display graphics, the pixels 11 in one column of any row and the pixels 11 'in the adjacent row and column are still partially overlapped in the horizontal direction H. Therefore, it is difficult to generate jaggies when displaying graphics such as oblique lines or curves, and smooth and continuous lines can be displayed. Therefore, the visual effect of the display device D can be optimized.

Of course, the above is only an example, and the arrangement of the display panel 1 can still be adjusted according to actual needs, and the present invention is not limited thereto.

It is worth mentioning that the existing display devices using red, green, blue, and white pixel arrangements due to the limitation of the arrangement method, cause it to easily generate discontinuous lines when displaying diagonal lines or curves and other graphics, which greatly reduces the visual effect. . In contrast, according to the embodiment of the present invention, the display device uses a special pixel arrangement so that each pixel partially overlaps with adjacent pixels in adjacent rows, so it can show continuous lines when displaying graphics such as diagonal lines or curves. Therefore, it can produce better visual effects.

In addition, according to the embodiment of the present invention, each pixel of the pixel arrangement of the display device may include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel. Therefore, a higher-brightness display effect can be provided. Reduced power consumption.

As shown in FIG. 4, the display panel 1 may include a plurality of pixels 11, and each pixel 11 may include a first sub-pixel 111A, a second sub-pixel 111B, a third sub-pixel 111C, and a fourth sub-pixel 111D.

As in the previous embodiment, the first sub-pixel 111A, the second sub-pixel 111B, the third sub-pixel 111C, and the fourth sub-pixel 111D may be arranged in a staggered manner to form the pixel 11, and two adjacent pixels in the horizontal direction H Among the pixels, the fourth sub-pixel 111D of one pixel will completely coincide with the first sub-pixel 111A of the other pixel, so that the pixels 11 in the same row can be formed in the same staggered arrangement, and the pixels 11 in this row The staggered arrangement may be opposite to the staggered arrangement of the pixels 11 in adjacent rows.

Different from the foregoing embodiment, for each pixel 11 in the first row, the lower half of the second sub-pixel 111B may be coincident with the upper half of the first sub-pixel 111A in the horizontal direction H, and the third sub-pixel The upper half of 111C may coincide with the lower half of the second sub-pixel 111B in the horizontal direction H, and the lower half of the fourth sub-pixel 111D may coincide with the upper half of the third sub-pixel 111C in the horizontal direction H. Conversely, for each pixel 11 in the second row, the upper half of the second sub-pixel 111B may coincide with the lower half of the first sub-pixel 111A in the horizontal direction H, and the lower half of the third sub-pixel 111C. In the horizontal direction H, it may overlap the upper half of the second sub-pixel 111B, and in the horizontal direction H, the upper half of the fourth sub-pixel 111D may overlap the lower half of the third sub-pixel 111C. The staggered arrangement of the pixels 11 in the third row may be the same as that of the pixels 11 in the first row, and the staggered arrangement of the pixels 11 in the fourth row may be the same as the pixels 11 in the second row. And so on.

As shown in FIG. 5, when the display device D uses the display panel 1 of this embodiment to display graphics, the pixels 11 in one column of any row and the pixels 11 ′ in the adjacent row and the next column may also have a portion in the horizontal direction H. Coincident, it is not easy to generate jaggedness when displaying graphics such as oblique lines or curves, and can display smooth and continuous lines, so the visual effect of the display device D can be optimized.

Of course, the above is only an example, and the arrangement of the display panel 1 can still be adjusted according to actual needs, and the present invention is not limited thereto.
