Patent ID: 7683871

Claim:
A display control device comprising: a gamma circuit producing and outputting a gray scale voltage and a selection drive circuit selecting the gray scale voltage on the basis of a pixel data displayed on a display device and outputting the selected gray scale voltage as a pixel driving signal to the display device, wherein the selection drive circuit includes an analog memory and holds the selected gray scale voltage in the analog memory; and wherein the drive circuit comprises: a capacitor holding an analog voltage; a first switch supplying/shutting down a voltage supplied to the capacitor; an amplifier supplying a voltage to be stored in the capacitor through the first switch; a second switch supplying/shutting down a gray scale voltage to be inputted into the amplifier from the selection drive circuit; and a third switch supplying/shutting down a voltage stored in the capacitor to the amplifier; wherein the first switch and the second switch are closed and the third switch is opened to store a gray scale voltage inputted from the selection drive circuit in the capacitor through the amplifier, and wherein the first switch and the second switch are opened and the third switch is closed to reproduce and output a voltage stored in the capacitor through the amplifier.
