ABSTRACT:
A display control circuit, an electro-optical device, a display device and a display control method, which can make a high image quality and a low power consumption compatible and which are suited for an active matrix type liquid crystal panel. An LCD controller comprises a control circuit, a RAM, a host I/O and an LCD I/O. The control circuit includes a command sequencer, a command setting register and a control signal generation circuit. The command setting register includes a signal driver setting register, a scan driver setting register and a control register. On the basis of the command setting register set by a host, the command sequencer sets a display area (or a non-display area) at a line block unit for a signal driver and a scan driver. The LCD controller supplies the image data corresponding to the set display area and controls the display timing for those drivers and a power circuit.
