Problems solved by technology

This phenomenon can be alleviated to a certain extent by using edge nine-point filtering, but the display effect is still not satisfactory, and 2 lines of cache are required on the hardware, which will increase the hardware cost

Abstract

The invention discloses an image data processing method and device. The method includes the following steps: A. Receive a first display data combination, wherein the first display data combination includes a first predetermined number of red, green and blue sub-pixel display data; B. converting the first display data combination into a second display data combination, wherein the second display data combination includes a first predetermined number of red, green, blue and white sub-pixel display data; C. converting the second display data The data combination is converted into a third display data combination, wherein the third display data combination includes any three of the first predetermined number of red, green, blue and white sub-pixel display data, and the third display data combination is used to provide Pixel array to display the corresponding image in the pixel array. The invention can improve the contrast of the picture under the premise of effectively keeping the resolution, hue and saturation of the original image unchanged.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to an image data processing method and device. [0003] 【Background technique】 [0004] In a conventional display panel, R (Red, red) G (Green, green) B (Blue, blue) is generally displayed as a pixel. [0005] Currently, there is a display panel that displays RGBW (White, white) as one pixel. [0006] Due to the addition of W sub-pixels in RGBW display technology, the backlight penetration rate will become higher, so the brightness of the white screen will also increase, and the screen contrast will also be improved. [0007] Since RGBW adds W sub-pixels and arranges 3 sub-pixels as one pixel, in order not to change the resolution of the display panel, in the pixel arrangement of 1 row, every 4 consecutive pixels (12 sub-pixels in total) ) has 3 pixels with W sub-pixels instead of B, G and R sub-pixels respectively. [0008] In practice, the inventors found that the prio...
