Document Type and Number:
Japanese Patent JP2005266178
Kind Code:
A
Abstract:

To provide a driver for a display device, by which power consumption can be reduced in a stand-by state, the display device and a method for driving the display device.

The driver for the display device is provided with a data signal line driving circuit SD provided with a shift register 1 for shifting respective levels by boosting a source clock signal and applying the boosted source clock signal to respective flip-flops and constituted so as to sample a multigradation data signal DAT, by a sampling circuit SAMP on the basis of respective outputs from the shift register 1 and output sampled signals to a plurality of data signal lines SL; a control circuit for switching a full-screen display mode for displaying the whole display screen 12 and a partial screen display mode for displaying only a part of the display screen 12 with time division; a data preparing part LCDC for generating fixed voltage data writing signal PVI consisting of fixed voltage; and a selecting signal PCTL for directly sampling the fixed voltage data writing signal PVI for a non-display part of the partial picture display mode and outputting the sampled signal to a plurality of data signal lines SL.
