GAMMA BUFFER OUTPUT COMPENSATING CIRCUIT, DRIVE CIRCUIT AND RESISTANCE VALUE SETTING METHOD THEREOF

摘要

Disclosed are a gamma buffer output compensating circuit, a drive circuit and a resistance value setting method thereof. The gamma buffer output compensating circuit comprises a group of variable compensating resistance modules which are respectively connected to each output end of the gamma buffer and have adjustable resistance values. By arranging the variable compensating resistance modules with adjustable resistance values before each output end of the gamma buffer to replace existing compensating resistors with constant values, the compensating resistance value before each output end can be adjusted through external operation, and the same compensating circuit is applicable to different machine types. The development of the gamma buffer output compensating circuit can be directly completed in advance without taking the difference of various machine types into consideration, and proper resistance values of the compensating resistors can be debugged later, and thereby, the generality of the gamma buffer is improved, and the development cycle of the machine types is shortened.
