More Information
Summary:A Gamma voltage driving circuit includes a setting circuit, a Gamma voltage generator, and a plurality of voltage output modules. The setting circuit respectively outputs a plurality of Gamma voltage setting signals at different time slots. The Gamma voltage generator respectively transforms the plurality of Gamma voltage setting signals into a plurality of corresponding voltage levels. The plurality of voltage output modules respectively provides voltage outputs at different time slots. Each voltage output module includes a plurality of voltage output circuits and a plurality of output control circuits. Each voltage output circuit includes a voltage selecting unit and an output buffering unit. The output control circuit controls the voltage output circuit to selectively output Gamma voltages.
