OLED module gamma adjustment method and system based on multi-objective correlation mathematical model

Abstract

The invention discloses a Gamma adjusting and recalibrating method and a Gamma adjusting and recalibrating device of an OLED module based on a multi-objective relational mathematic model. The method comprises the following steps: (1) establishing an objective function; and (2) establishing a constraint condition, wherein R, G and B register values of all the binding points of the module are in positive linear or negative linear dependence, the multi-objective relation optimization is converted into single-objective optimization, the double-objective optimization is converted into single-objective optimization, and finally, the R, G and B register values corresponding to F are solved and are output to R, G and B registers corresponding to the gray scale binding point m in a module chip according to setting. According to the technical scheme, the diversified mode of gamma adjustment is supported, the features of platformization and parallelism are realized, and the method and the systemhave the advantages of efficiency and stability in adjusting and good gradual change effect. The experimental result shows that with the provided mathematic model, the complexity can be effectively reduced, the conventional algorithm is converted into algorithm and calculation, the adjusting and recalibrating efficiency is very ideal, and the problems including that the module is poor in consistency are solved.

Description

technical field [0001] The invention relates to the field of display and testing of liquid crystal modules, in particular to a method and system for adjusting Gamma of an OLED module based on a multi-object correlation mathematical model. Background technique [0002] With the development of OLED-related technologies and the increase of production capacity under construction at home and abroad, the market for OLED products is expanding rapidly, and smartphones will be the largest market for OLEDs. In the future, wearable devices, TVs, lighting, virtual reality and automobiles will OLED will be widely adopted. The human eye is more sensitive to grayscale changes than to chromaticity changes, and to low luminance changes than to high luminance changes. The module does gamma correction (Gamma tuning). [0003] OLED module Gamma and white balance, as complex and nonlinear objects, need to find a corresponding mathematical model, and directly calculate independent variables in ...
