Display signal processing device and display device |
摘要 |
A display signal processing device includes a reference gradation voltage generating circuit that generates ten reference gradation voltages, and a D/A converting circuit that converts a video signal to a pixel voltage by selectively using the ten reference gradation voltages obtained from the reference gradation voltage generating circuit. The reference gradation voltage generating circuit includes four variable voltage generating sections that generate output voltages, which are varied for gamma correction, and nine resistors that are connected to divide difference voltages obtained between output terminals of the four variable voltage generating sections into the ten reference gradation voltages.
