Abstract

The present invention provides an image display method, comprising: acquiring test gray scale data for pixel data of test image data, and acquiring the gray scale compensation table according to the test gray scale data and the preset gray scale data; converting the original image data into processed image data; implementing gray scale data compensation to pixel data in the processed image data according to a gray scale compensation table; implementing display operation with the processed image data after the gray scale data compensation.

First claim

What is claimed is:

1. An image display method, comprising:
inputting original image data, wherein the original image data is employed to implement sharing pixel display on a display panel having a plurality of pixels, and wherein a pixel of the plurality of pixels of the display panel comprises a red sub pixel, a green sub pixel, a blue sub pixel, a white sub pixel, wherein in the sharing pixel display, the pixel shares one of the red sub-pixel, the green sub-pixel and the blue sub-pixel with an adjacent pixel;
converting the original image data into processed image data, wherein the processed image data is employed to implement independent pixel display on the display panel, wherein in the independent pixel display, the pixel shares none of the red sub-pixel, the green sub-pixel and the blue sub-pixel with any adjacent pixel;
implementing gray scale data compensation to pixel data in the processed image data according to a gray scale compensation table; and
implementing display operation on the display panel with the processed image data after the gray scale data compensation,
wherein the gray scale data compensation table is generated by steps of:
acquiring test gray scale data under a plurality of various preset grey scales for pixel data of test image data, and respectively acquiring test gray scale data under the same preset grey scale for each kind of pixel data of test image data, wherein the test image data is employed to implement independent pixel display on the display panel; and
acquiring the gray scale compensation table according to the test gray scale data and the preset gray scale data.

2. The image display method according to claim 1 , wherein the step of implementing gray scale data compensation to pixel data in the processed image data according to a gray scale compensation table comprises:
acquiring first gray scale data of pixel data in the processed image data;
acquiring gray scale compensation values corresponding to the first gray scale data from the first gray scale data and the gray scale compensation table via a preset rule; and
implementing compensation to the first gray scale data of pixel data in the processed image data according to the gray scale compensation values.

3. The image display method according to claim 2 , wherein after the step of acquiring the gray scale compensation values corresponding to the first gray scale data, the method further comprises: storing the gray scale compensation values corresponding to the first gray scale data.

4. The image display method according to claim 1 , wherein the pixel of the display panel further comprises a yellow sub pixel.
