Abstract

The invention discloses an automatic LCD splicing adjustment type white balance realizing method and system. The method comprises the steps of displaying a selected test image on an LCD spliced screen; setting the target x, y color coordinates and gamma ray curves of 100% R, G, B, W images of a target gamut, and conducting conversion to target X, Y, Z values; acquiring the actual X, Y, Z values of each LCD screen body in the LCD spliced screen through a chromathermograph, obtaining a gamut compensation value through comparison with the target X, Y, Z values and calculation, and conducting gamut correction according to the gamut compensation value; displaying pre-stored specific images on the LCD spliced screen; acquiring multiple pixel points through a color analyzer, conducting margin calculation with the intermediate point among the pixel points to obtain a light compensation value, and conducting chromaticity and brightness uniformity correction according to the light compensation value. According to the method and system, assembly and disassembly of the LCD spliced screen are not needed, multiple areas of the screen can be debugged at the same time, and white balance adjustment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of LCD display screens, in particular to a method and system for automatically adjusting the white balance of LCD splicing. Background technique [0002] As the large-screen splicing system is more and more widely used in various industries, it has greatly promoted the development of enterprises and the construction of information technology. Because the LCD splicing wall has the advantages of low power consumption, light weight, long life (generally can work for 50,000 hours), no radiation, and uniform brightness of the screen, it has become a leader in the large-screen splicing industry once it is launched. [0003] As there are more and more manufacturers producing LCD splicing large screens in the entire market, the product borders are getting narrower and narrower. However, after multiple LCD screens are spliced ​​together, the uniformity of the LCD screen is very poor, such as slight color difference ...
