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.
