OLED module Gamma adjustment and calibration method based on linear interpolation calculation

Abstract

The invention discloses an OLED module Gamma adjustment and calibration method based on linear interpolation calculation. The method comprises the steps of obtaining a brightness target value and a color coordinate target value of each target binding point according to the brightness value of a highest gray scale W255 and the brightness value of a least gray scale W0; selecting an adjusting and calibrating fixed point from the target binding points, and adjusting the R register value and G register value of the adjusting and calibrating fixed point so that a color coordinate is in an error range of the color coordinate target value; adjusting the R register value, the G register value and the B register value of the adjusting and calibrating fixed point so that the brightness value is in an error range of the brightness target value; and calculating the R register value, the G register value and the B register value of other target binding points according to the R register value, the G register value and the B register value of the adjusting and calibrating fixed point according to a linear interpolation method. The method can be used for performing brightness and coordinate adjustment on an OLED module finished product after an IC is bound so that the brightness satisfies a Gamma 2.2 curve and the color temperature accords with a CIE 1931 standard. Furthermore the adjusted register is solidified into the EEProm of the OLED module IC so that a display effect which most accords with a human eye vision curve and a specific color temperature is displayed after the OLED module is electrified.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and specifically relates to a method for adjusting the Gamma of an OLED module based on linear interpolation calculation, which adjusts the brightness and chromaticity of an OLED module product bound with an IC, so that the brightness meets the Gamma2.2 curve , the color temperature conforms to the CIE1931 standard, and the curing adjustment register is stored in the EEProm of the OLED module IC, so that the OLED module will present a display effect that best conforms to the human eye's visual curve and specific color temperature when it is lit. Background technique [0002] OLED is regarded as a new flat panel display technology with the greatest development potential after LCD and PDP. China, as the world's largest manufacturer and consumer of electronic products, is also regarded as the world's largest OLED application market. With the continuous increase of terminal demand for consumer ...

Problems solved by technology

[0006] At present, the gamma tuning devices developed by domestic and foreign testing equipment manufacturers support too many adjustment binding points for certain types of modules, and routine adjustment is performed on each binding point. There is a problem that the adjustment speed is too slow, which affects OLED modules. Manufacturer capacity
