Abstract

The invention discloses an OLED module Gamma adjustment and calibration method and device wherein the device comprises a PC, a controller, an image generator and an optical detection instrument. The method comprises the following steps: obtaining the theoretical brightness values of a target binding point according to the brightness value of the highest gray level W255 and the brightness value of the lowest gray level W0, and determining the target brightness value and the target color coordinate value of the target binding point; adjusting the R and G register values so that the color coordinate value of the target binding point falls within the error range of the target color coordinate value; adjusting the R, G and B register values so that the brightness value of the target binding point falls within the error range of the target brightness value; According to the invention, it is possible to adjust the brightness and coordinate of a finished OLED module bounded with IC so that the brightness meets a Gamma 2.2 curve, that the color temperature conforms to the CIE 1931 standard, and that the registers are solidified and adjusted to the EEProm of the OLED module's IC, making the OLED module present the visual curves most consistent with the human eye and achieve the display effect with a specific color temperature.

Description
