Abstract

The invention provides a pixel rendering method, and the method comprises the steps: acquiring gray-scale values of three primary color components of original image pixels; converting the gray-scale values of the three primary color components of the original image pixels into gray-scale values of three primary color components and an initial compensation component of compensation image pixels; sampling a compensation image, and extracting the gray-scale values of the previous two primary color components of first one compensation image pixel in every group and the third primary color component of the next compensation image pixel and the compensation component; and setting the gray-scale values of the previous two primary color components of first one compensation image pixel in every group and the third primary color component of the next compensation image pixel and the compensation component as a gray-scale value of each corresponding sub-pixel in each line of screen pixels. According to the invention, more sub-pixel and image details loss is avoided, and the data loss amount is reduced from 2 / 3 in the prior art to 1 / 2, so that the severe image blurring can be avoided.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a pixel rendering method, a pixel rendering device and a display device. Background technique

[0002] A digital image usually includes several image pixels, and each image pixel has a finite number of discrete color values. For example, these color values ​​are the grayscale values ​​of the red component, the green component and the blue component in the red-green-blue (RGB, RedGreenBlue) color space. The digital image can be displayed on the display by driving a plurality of screen pixels arranged in an array on the display according to the digital image.

[0003] When performing display according to the traditional sub-pixel driving method, one sub-pixel is used to display the value of one color component in an image pixel. In order to increase the resolution of the display, more image pixels need to be displayed, that is to say, the number of sub-pixels on the disp...
