Problems solved by technology

[0003] However, in a display panel with high image quality, when its resolution (that is, the amount of pixels per inch (pixel per inch, ppi)) is greater than the highest pixel density that human eyes can distinguish (that is, retinal resolution, For example, at 300ppi), the brightness visual center of every two pixels in the display panel will not be judged by human eyes
In other words, if the distance between each adjacent red, green, and basket pixel in the display panel is too small, the different color lights produced by adjacent red, green, and basket pixels will cause color mixing problems
[0004] In addition, while improving the resolution of the display panel, its transmittance will be relatively reduced, which will lead to a decrease in the brightness of the display panel

Embodiment Construction

[0054] In order to improve the transmittance, brightness and clarity of the display panel, the present invention reduces the pixel density of the display panel by arranging red pixels, blue pixels, green pixels and white pixels of sub-pixels of different colors, and designing a suitable algorithm Therefore, when displaying images, the display panel can have good pixel transmittance, high brightness and definition at the same time. Based on this, the problem of color mixing caused by different colored lights generated by sub-pixels in the high-quality display panel is effectively improved.

[0055] figure 1 It is a schematic top view of a pixel array of a display panel according to some exemplary embodiments of the present invention.

[0056] Please refer to figure 1, the display panel 1000 includes a plurality of sub-pixel groups 100 , and the sub-pixel groups 100 are arranged repeatedly to form a pixel array 1200 . In this exemplary embodiment, each sub-pixel group 100 is ...

Abstract

The present invention provides a display panel, which comprises a plurality of sub-pixel groups. The sub-pixel groups are repeatedly arranged to form a pixel array. A plurality of sets of pixel data are written into each sub-pixel group. Each sub-pixel group comprises a plurality of main-genre pixel units and a plurality of sub-genre pixel units. A group of pixel data, among the above pixel data, is written into each main-genre pixel unit. At least one group of pixel data, among the above pixel data, is written into each sub-genre pixel unit. The main-genre pixel units are arranged to form a geometric shape in the pixel array to surround a single sub-genre pixel unit among all the sub-genre pixel units.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a display panel. Background technique [0002] With the advancement of display technology, consumers have higher and higher requirements for display devices. Therefore, the development of display panels is gradually moving towards the direction of thinness, high image quality, and low power consumption. Especially, for the display device, low power consumption and high brightness are the focus of people's attention. [0003] However, in a display panel with high image quality, when its resolution (that is, the amount of pixels per inch (pixel per inch, ppi)) is greater than the highest pixel density that human eyes can distinguish (that is, retinal resolution, For example, when 300ppi), the brightness visual center of every two pixels in the display panel cannot be determined by human eyes. In other words, if the distance between each adjacent red, green, and basket pixel in ...
