发明名称 Gamma voltage conversion device
摘要 Gamma voltage conversion device includes a gamma voltage conversion circuit, an amplifier, and a gamma voltage adjusting circuit. The gamma voltage conversion circuit generates a first gamma voltage conformed to a first gamma curve according to a grey level. The amplifier includes a first input end receiving the first gamma voltage, a second end, and an output end. The amplifier outputs the first or a second gamma voltage conformed to a second gamma curve according to the grey level according to the first and the second ends of the amplifier. The gamma voltage adjusting circuit coupled between the second input end and the output end of the amplifier controls the amplifier to output the first or the second gamma voltage as the gamma driving voltage according to the grey level and a gamma curve selection signal.
