Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a mixed grayscale modulation high-grayscale high-definition image display method and a device thereof. Background technique [0002] The research on TFT-LCD displays has been pursuing high-definition, ultra-high grayscale and high restoration of displayed images and videos. However, it is far from enough to focus on the improvement of TFT-LCD panel materials or the front-end processing of image editing code compression. We must also pay attention to the conversion process from digital image information to physical illuminants, as well as the brightness of illuminants and human vision. According to the relationship between the characteristics, a timing control and grayscale control method suitable for high-definition TFT-LCD is found. [0003] When the gray scale continues to increase, the traditional gray scale modulation method will encounter some problems in t...

AI Technical Summary

Problems solved by technology

[0004] Generally, in a high-resolution, high-gray-scale TFT-LCD display control system, any traditional gray-scale modulation method alone cannot meet the needs of high-quality display. Therefore, when fully considering the TFT-LCD On the basis of performance indication, it is necessary to combine the existing technical level and the visual characteristics of the human eye to improve the traditional grayscale modulation method and design a multi-grayscale modulation architecture suitable for modern TFT-LCD display
