Method for eliminating colorful edge of display graph and display device

Abstract

The invention discloses a method for eliminating a colorful edge of a display graph and a display device. The method for eliminating the colorful edge of the display graph comprises the steps of obtaining multiple edge pixels corresponding to a display graph edge in a display screen, respectively obtaining first pixels and second pixels which are in the same line with the edge pixels and are adjacent and third pixels and fourth pixels which are in the same column and are adjacent, adopting the edge pixels corresponding to the first pixels, the second pixels, the third pixels and the fourth pixels to perform compensation algorithm processing so as to obtain gray-scale values after the edge pixels are processed, adjusting the gray-scale values of the multiple edge pixels to be corresponding processed gray-scale values. By the adoption of the technical scheme, the advantage of eliminating the colorful edge of the display graph in the display screen is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and a display device for eliminating color fringes of displayed graphics. Background technique [0002] Organic light-emitting display devices have beneficial effects such as self-illumination, no need for backlight, thinness, large viewing angle, and low energy consumption, and are favored by developers and users. [0003] With the continuous development of organic light-emitting display technology, the pixel arrangement of organic light-emitting display devices is no longer limited to the traditional standard pixel arrangement, and many other pixel arrangements have emerged, such as Pentile arrangement or rhombus arrangement. The size of some sub-pixels in the above-mentioned pentile arrangement and rhombus arrangement becomes larger, which is beneficial to reduce the difficulty of manufacturing the organic light-emitting display device. However, in these two arrangem...

Problems solved by technology

The size of some sub-pixels in the above-mentioned pentile arrangement and rhombus arrangement becomes larger, which is beneficial to reduce the difficulty of manufacturing the organic light-emitting display device. However, in these two arrangements, the sizes of the sub-pixels of the three color types arranged at the edge of the pixel array are not complete. In the same way, normal color mixing cannot be obtained to obtain white light, and the color type corresponding to the larger sub-pixel is more obvious, which in turn makes the edge of the display device present the corresponding color, and the phenomenon of color fringing appears
