Display control circuit

1. 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.

2. The display control circuit according to claim 1 , wherein

the gamma circuit outputs a plurality of gray scale voltages in a time division manner and

the selection drive circuit stores a display gray scale voltage predetermined in accordance with the pixel data of the plurality of gray scale voltages to be inputted in a time division manner in the analog memory.

3. The display control circuit according to claim 1 , wherein

the plurality of gray scale voltages comprise even-numbered gray scale voltages and odd-numbered gray scale voltages of gray scale voltages produced by the gamma circuit.
