Problems solved by technology

If this group of P-Gamma values ​​is not suitable for LCD panels, you need to use the Auto P-Gamma technology for a debugging, which takes about 20s, which increases a lot of testing time and leads to a significant reduction in production line efficiency

Abstract

The invention discloses a gamma curve debugging method. The method comprises the following steps: subjecting a first liquid crystal display device to a N-th liquid crystal display device to a gamma curve debugging treatment, after debugging, recording the burned N gray scale voltages (N is an integer more than 2); calculating the average gray scale voltage of N gray scale voltages; burning the average grey scale voltage into a (N+1)-th liquid crystal display device; and subjecting the (N+1)-th liquid crystal display device to a gamma curve debugging treatment. The provided gamma curve debugging method can improve the gamma curve debugging efficiency of liquid crystal display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display device debugging, in particular to a gamma curve debugging method. Background technique [0002] With the continuous development of electronic products, the application of Thin Film Transistor Liquid Crystal Display (TFT-LCD) is becoming more and more mature. [0003] When the user watches the display screen of the liquid crystal display device, since the perception of the human eye is different from the actual video data, the brightness and gray scale curve of the display screen will not be a straight line of equal length. , there will be different gamma curves (Gamma). [0004] Generally, a set of P-Gamma values ​​(gray scale voltages) are temporarily stored in the P-Gamma IC (programmable gamma correction buffer circuit chip) of the control board of the liquid crystal display device. It was debugged during the design stage, but due to the differences in the manufacturing proces...
