Image display driving method, image display driving device and image display driving equipment

Abstract

An embodiment of the invention discloses an image display driving method, an image display driving device and image display driving equipment, relates to the field of image processing, and aims to improve image display effect. The image display driving method includes according to gray-scale values and preset linear arrangement sequences of sub pixels in adjacent pixels, judging whether the number of the sub pixels, with the continuous gray-scale values being zero, between the white luminous sub pixels with the gray-scale values not being zero and the luminous sub pixels with the gray-scale values not being zero in the adjacent pixels is larger than a preset threshold value; if yes, determining mixed white light brightness formed by mixing of the three primary colors of sub pixels in equal gray-scale proportion according to partial brightness of the white luminous sub pixels; according to the gray-scale values of the three primary colors corresponding to the mixed white light brightness, driving the three primary colors of sub pixels in a first pixel to be displayed, and according to the gray-scale values corresponding to other brightness, except brightness corresponding to the mixed white light brightness, in the brightness of the white sub pixels, driving the white sub pixels in the first pixel to be displayed.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image display driving method, device and equipment. Background technique [0002] At present, the traditional ultra-high-definition display technology mainly includes RGB (red, green, blue) ultra-high-definition display technology and RGBW (red, green, blue, white) ultra-high-definition display technology. Among them, the RGBW ultra-high-definition display technology adds white (White) sub-pixels (Sub-pixel) to the traditional RGB three primary colors (ie, red, green, blue) to form an RGBW structure, that is, each pixel of the display device They are all composed of red sub-pixels, green sub-pixels, blue sub-pixels (that is, three primary color sub-pixels) and white sub-pixels. By adjusting the operating voltage or current used to drive different sub-pixels, the brightness of different sub-pixels can be adjusted ( Also known as the grayscale value), which ultimately ma...

Problems solved by technology

[0006] It can be seen that in the prior art, when a pixel with a special color is required, it is very likely that the arrangement of the sub-pixels in the pixel is different, resulting in an obvious phenomenon of black lines
