Problems solved by technology

[0003] In order to improve the visual effect, people put forward higher and higher requirements for the resolution of the display device (the number of pixels in a unit size); this requires the size of the sub-pixel to be smaller and smaller, but due to the limitation of the process, the size of the sub-pixel cannot be unlimited zoom out

Embodiment Construction

[0039] In order to improve the display effect when the size of the sub-pixels is fixed, a virtual display design in a rainbow (Rainbow) arrangement is proposed. In this design, the arrangement of RGB (Red Green Blue, red, green and blue) sub-pixels is a rainbow (Rainbow) arrangement, such as figure 1 As shown, the display panel includes several pixel groups 1 composed of a plurality of sub-pixels arranged in a matrix, and each pixel group 1 includes 4 rows of sub-pixels and 3 columns of sub-pixels, which are red sub-pixels R, green sub-pixels G and blue sub-pixels respectively. Pixel B; blue pixel B, red sub-pixel R and green sub-pixel G; green sub-pixel G, blue sub-pixel B and red sub-pixel R; blue sub-pixel B, red sub-pixel R and green sub-pixel G; and a gate line Gate connected to each row of sub-pixels, and a data line Data connected to each column of sub-pixels. Compared with the traditional display panel, the above-mentioned virtually designed display panel can reduce t...

Abstract

The invention discloses a display panel, a display method thereof and a display device. It is confirmed that the received picture to be displayed is a preset solid color picture; for each green sub-pixel, the gray scale value corresponding to the green sub-pixel is compared with The difference between the gray scale values ​​corresponding to the red sub-pixel or the blue sub-pixel at the corresponding position in the previous row; Set the value for display; or, if the difference is greater than 0, increase the grayscale value corresponding to the green sub-pixel by a preset value less than 5 for display. The charging amount of all green sub-pixels can be basically the same, thereby avoiding brightness differences and eliminating poor light and dark stripes on the display surface.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display method and a display device thereof. Background technique [0002] In conventional liquid crystal display devices and organic light-emitting diode (OLED) display devices, each point (pixel) is composed of multiple sub-pixels to display colors through light mixing, for example, each pixel is composed of red sub-pixels, green sub-pixels, blue sub-pixels, and blue sub-pixels. Each color sub-pixel consists of one (RGB mode). [0003] In order to improve the visual effect, people put forward higher and higher requirements for the resolution of the display device (the number of pixels in a unit size); this requires the size of the sub-pixel to be smaller and smaller, but due to the limitation of the process, the size of the sub-pixel cannot be unlimited zoom out. Contents of the invention [0004] In view of this, the embodiments of the present invention...
