Problems solved by technology

When the liquid crystal display is at a higher resolution, it is easy to produce pixel distortion, which has a certain impact on the display effect, and the number of displayed colors is limited compared with the cathode ray picture tube. Although some liquid crystal displays claim to be able to achieve 32-bit color, they all It is realized by the dithering algorithm, and there is still a gap with the real 32-bit color

Abstract

A method for improving the display effect of colors of a liquid crystal display (LCD) by mapping of a color range belongs to the field of information technology and comprises the following steps: firstly, the LCD and a cathode ray tube display are connected with a computer, and the computer is turned on; secondly, the two displays are regulated by a colorimeter, and meanwhile, rectangular color lumps in different colors are inputted into the displays and simultaneously displayed on the two displays; thirdly, the scopes of the color ranges of the displays are measured by the colorimeter, and a coordinate figure of a peak of the color range is obtained; and fourthly, the coordinate of the peak of the color range of the LCD is mapped to the coordinate of the peak of the color range of the cathode ray tube display by the mapping method of the color range; if picture effects are same, the improved display effect of the color of the picture of the LCD is obtained, and a matrix circuit is added in the LCD; and if the picture effects are different, the operation returns to the third step, and the scopes of the color ranges of the displays are measured again until the picture effects of the LCD and the cathode ray tube display are same.

Description

technical field [0001] The invention relates to a method for improving the color display effect of a liquid crystal display through color gamut mapping, and belongs to the field of information technology. Background technique [0002] Compared with the traditional cathode ray picture tube display, although the liquid crystal display has the advantages of high definition and small size, it still lags behind the cathode ray picture tube display in terms of color performance and saturation. CRT monitors can display images perfectly at any resolution, and in theory, can display unlimited colors. As we all know, the higher the number of monitors, the more colors the monitor displays, the richer the colors, and the better the picture quality. When the liquid crystal display is at a higher resolution, it is easy to produce pixel distortion, which has a certain impact on the display effect, and the number of displayed colors is limited compared with the cathode ray picture tube. Al...
