Abstract

The invention provides an image display method and device. The method includes: according to the acquired image data, determining a first pixel point to be processed in the image data; the gray scale value of the first pixel point is within a preset gray scale value range; according to the first pixel point The grayscale value of the pixel point and the preset corresponding relationship determine the grayscale combination corresponding to the first pixel point; the corresponding relationship is the corresponding relationship between the grayscale value of the pixel point and the grayscale combination; the grayscale combination It includes: at least two grayscale values ​​and the proportion of display time corresponding to each grayscale value; the first pixel is displayed according to the grayscale combination corresponding to the first pixel. The method of the embodiment of the present invention improves the degree of color cast of the VA liquid crystal panel when viewed from a side view angle.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an image display method and device. Background technique [0002] For vertical alignment (Vertical Alignment, VA for short) liquid crystal panels, as the viewing angle increases, the color gradually becomes lighter, that is, the problem of color shift. This is because the voltage and transmittance curves are different when viewing from a front viewing angle and viewing from a side viewing angle. When viewing from a side viewing angle, the brightness of the middle and low gray scales increases faster than when viewing from a front viewing angle. [0003] In the related art, the partition of one sub-pixel is changed into multiple partitions by using the spatial region method, that is, the manner of forming 8 domains. The original brightness displayed in one area is displayed by two small areas with different brightness, so that a brighter gray scale and a darker gray scal...
