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 a method and a device for image data processing. The method comprises the following steps: A receiving a first display data combination, wherein the first display data combination comprises red, green, and blue sub-pixel display data in first preset number; B, converting the first display data combination to a second display data combination, wherein the second display data combination comprises red, green, blue, and white sub-pixel display data in the first preset number; C, and converting the second display data combination to third display data combination, wherein the third display data combination comprises any three ones of the red, green, blue, and white sub-pixel display data in the first preset number, the third display data combination being used for providing to a pixel array, so as to display corresponding images in the pixel array. The method and the device can improve frame contrast on the premise of effectively maintaining resolution, tone, and saturation of an original image unchanged.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an image data processing method and device. 【Background technique】 [0002] In a conventional display panel, R (Red, red) G (Green, green) B (Blue, blue) is generally displayed as a pixel. [0003] Currently, there is a display panel that displays RGBW (White, white) as one pixel. [0004] 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. [0005] 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. [0006] In practice, the inventors found that the prior art has at le...
