Problems solved by technology

However, due to the difficulty in controlling the quality of the manufacturing process, it cannot be guaranteed that the light transmission performance of each LCD screen is the same, which will lead to inaccurate gamma correction
After using the gamma data obtained from sample debugging and burning it into the gamma driver chip, the gamma curve value of the final batch of panels measured is between 2.2±0.6, and the debugging effect is not good.
If the gamma debugging of each grayscale of each binding point is performed on each panel, it will take a lot of time and cost to debug, which will greatly reduce the production efficiency

Abstract

The invention provides gamma debugging methods for display panels. A method comprises the steps of obtaining brightness of boundary gray scales through utilization of a sensor; obtaining predicted brightness of other binding pixel gray scales through utilization of boundary brightness; adjusting binding pixel gray scale voltages, thereby enabling the brightness of the binding pixel gray scales tobe equal to or close to the predicted brightness; obtaining gamma voltage data corresponding to the boundary gray scale brightness and the binding pixel gray scale brightness; and storing the gamma voltage data to a gamma drive chip, thereby enabling the display panels have debugged gamma curves when the display panels are operated.

Description

technical field [0001] The present application relates to the display field, in particular to a gamma debugging method of a display panel. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display, thin film transistor display device) is one of the main types of flat panel display devices at present, and has become an important display platform in modern IT and video products. The system motherboard of the thin film transistor display device connects the R / G / B compressed signal, control signal and power to the connector (Connector) on the printed circuit (PCB) board through the wire, and the data is controlled by the timing on the printed circuit board. After the chip (TCON, Timing Controller) is processed, it is connected to the display area through the PCB board, the source driver chip (S-COF, Source-Chip on Film) and the gate driver chip (G-COF, Gate-Chip on Film) , so that the display device can obtai...
