ABSTRACT:
A display control circuit (100) that may have a reduced power consumption has been disclosed. A display control (100) may include a plurality of output cells (3-1to3-N). Each output cell may include an amplifying circuit (35) for driving an output terminal (PS) to essentially a gray level voltage according to a display data (DIN). Amplifying circuit (35) may include a dead zone in which an output may be a high impedance when the output terminal is substantially the gray level voltage. An amplifying circuit (21) may be included to provide a drive for the output terminal (PS) in the vicinity of the gray level voltage. Amplifying circuit (21) may not include the dead zone. In this way, by providing the large drive by amplifying circuit (35) and a smaller drive strength by amplifying circuit (21), current consumption may be reduced.
