<P>PROBLEM TO BE SOLVED: To provide a display control circuit and a liquid crystal display (LCD) driver capable of attaining full color display with simple configuration. <P>SOLUTION: The display control circuit is provided with: a display RAM 1 for storing a pixel data; n pieces of pixel voltage generating circuits 2 for supplying an analog pixel voltage to a corresponding signal line; an address generating circuit 3 for generating a read-out address signal of the display RAM 1; and a frame number generating device 4 for generating a frame number to be displayed. An OD[5:0] of 6 bits and a carry signal CA is output form a frame control circuit 12, and one analog switch 23 corresponding to the carry signal CA is added in a DAC 13, and one of analog reference voltages of 65 kinds is output according to the frame, and thereby, the number of grayscale of four times of 2<SP>6</SP>=64 is attained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
