Gamma control circuit and method thereof |
摘要 |
A gamma control circuit includes a first gray-scale voltage selection unit that selects and outputs a highest gray-scale voltage and a lowest gray-scale voltage from among a plurality of first voltages present between a first supply voltage and a second supply voltage. A second gray-scale voltage selection unit receives the highest and lowest gray-scale voltages and selects and outputs a first intermediate voltage and a second intermediate voltage between the highest and lowest gray-scale voltages. A third gray-scale voltage selection unit receives the highest and lowest gray-scale voltages and the first and second intermediate voltages and generates a plurality of reference voltages from the received voltages. A gray-scale voltage generation unit receives the highest and lowest gray-scale voltages and the plurality of reference voltages and outputs a plurality of gray-scale voltages. |
