Abstract

The invention relates to a fully automatic high-precision chromaticity and Gamma monitoring and adjustment system and method, which solves the technical problem of complicated operation. Buffers of anAnalog Gamma Curve (AGC) and a Digital Gamma Curve (DGC) of a display driver IC are corresponding to detection values of an optical detection instrument to form a closed loop circuit, and real-time dynamic adjustment is realized; and the optimal buffer value is calculated by integrating the DLL call by means of the Gamma intelligent algorithm, and finally the optimum value of the Gamma correlation buffer of each sample is solidified into an NVM of the driver IC to achieve the technical solution of automatically controlling the chromaticity, the color temperature and Gamma of each module; theproblem can be solved; and the fully automatic high-precision chromaticity and Gamma monitoring and adjustment system and method can be used in optical module testing.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to a fully automatic high-precision chromaticity and Gamma monitoring and adjustment system and method. Background technique [0002] With the improvement of living standards, people also put forward higher requirements for daily display. Especially in the area of ​​mobile phone display, the customer wants the chromaticity of the LCD module to be as consistent as possible, so that the effect of visual inspection is basically unbiased. This requires that the CIE, color temperature, Gamma, brightness and other related factors of the display module be reliable. Adjustments can be monitored. [0003] But at the same time, the industry is affected by the deviation of incoming materials such as backlights and pixels of different batches, and it is impossible to guarantee that the color temperature of each sample is consistent with the Gamma on the module side. Nowadays, the Gamma curve an...
