Abstract

The invention discloses a module Gamma correction method and system based on curve matching. The method comprises the following steps: establishing a reference Gamma curve function by acquiring a modulation coefficient, a modulation index and a deviation value of a reference module; under the reference binding point, obtaining a predicted deviation value of the to-be-corrected module by utilizingthe register reference modulation value, the register modulation value of the to-be-corrected module and the deviation value of the reference module; constructing a predicted Gamma curve of the to-be-corrected module by utilizing the modulation coefficient of the reference module, the modulation index of the reference module and the predicted deviation value of the to-be-corrected module; obtaining register prediction initial values under all binding points by utilizing the prediction Gamma curve of the to-be-corrected module; performing gamma correction on the to-be-corrected module by usingthe register prediction initial values under all the binding points, so that the accuracy of the module Gamma correction initial value is improved, the Gamma correction adjustment frequency is reduced, and the Gamma correction efficiency of the module is improved.

Description

technical field [0001] The invention belongs to the field of module calibration, and in particular relates to a module Gamma calibration method and system based on curve matching. Background technique [0002] Organic Light-Emitting Diode (OLED) display, also known as organic electroluminescent display, occupies a pivotal position in the display industry today. It is a different type of product from thin-film transistor liquid crystal display (TFT-LCD). The former has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, high response rate, full color and simple manufacturing process. The basic structure of an OLED is a thin, transparent indium tin oxide (ITO) with semiconducting properties, which is connected to the positive electrode of the power, plus another metal cathode, which is wrapped into a sandwich structure. When the power is supplied to an appropriate voltage , the positive hole and the negative charge will combine in th...
