Title: Active matrix type display device
Inventor: TSUTSUI YUSUKE
IPC: G09G3/20
Filed: 2001-10-17
Granted: 2003-02-21
Abstract: An active matrix type display device is disclosed in the present invention to obtain low power consumption and high circuit precision for the active matrix type display device. One holding circuit 110 for holding image signal is proportionally disposed at plural pixels (two pixels, four pixels), and display operation is performed by switching the general operation mode and the memory operation mode. The holding circuit is composed of SRAM. Because the circuit area of SRAM is large, it is commonly used for plural pixels, where display is performed by decreasing pixel number in the memory operation mode. Thus, the area of one pixel can be decreased such that display with even higher precision can be conducted in the general operation mode. Additionally, by decreasing the number of holding circuit 110, more power consumption in the memory operation mode can be decreased as compared with the case of disposing the holding circuit at every pixel.
