DISPLAY DEVICE, ITS DRIVE CIRCUIT, AND DRIVE METHOD

摘要

It is possible to make display an impulse while suppressing complication of a drive circuit or increase of operation frequency in a hold type display device. In an active matrix type liquid crystal display device of the dot reverse drive method configured so as to short-circuit adjacent source lines by a predetermined period Tsh in every one horizontal scan period, a gate driver applies a pulse to turn on a TFT in the pixel formation unit as a scan signal G(j)(j = 1 to m) to be given to each scan signal line. In each frame period, a pixel data write pulse Pw is successively applied to a gate line GL1 to GLm. A black voltage application pulse Pb is applied within the predetermined period Tsh after elapse of a period (Thd) of about 2/3 frame from application of the pixel data write pulse Pw for each gate line GLj. The present invention may be applied to an active matrix type liquid crystal display device.
