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

Embodiment Construction

[0027] Such as figure 1 with 2 As shown, the high-gray-level high-definition image display method of the mixed gray-scale modulation comprises the following steps:

[0028] A. Data preprocessing and storage: preprocess the high-definition video signal, and then store it. More specifically, the high-definition video signal is received through the high-definition video input interface 1 and preprocessed by the front-end data processing module 2 , and then stored in the data memory 3 .

[0029] B. Dithering processing: perform dithering processing on the above-mentioned pre-processed high-definition video signal, and the dithering processing is to match the high-resolution image input signal with the gray level that the display terminal can display, so that the Higher resolution display information is assigned to adjacent spaces for display. More specifically, the dithering process is a rotational dithering process, and the rotational dithering process is to match the high-res...

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...
