发明名称 Gamma correction voltage generation device, and gamma correction device and display device using the same
摘要 A gamma correction voltage generation device relating to the invention has a plurality of sets, each comprising a data holding section for holding digital data inputted thereto, a digital-to-analog converter for converting the digital data held in the data holding section to an analog voltage, and a buffer for amplifying a capacity of current of the analog voltage and outputting the analog voltage, wherein the analog voltages are outputted from the buffers as gamma correction voltages. By this configuration, it becomes possible to perform a process of adjustments on the gamma correction voltages easily and efficiently.
