Patent ID: 8035605

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel having a plurality of pixels arranged to the intersections of a plurality of vertical and horizontal scan lines forming a matrix display, and connected to a plurality of switches respectively; a liquid crystal display control unit having a vertical driving circuit and a horizontal driving circuit, wherein the vertical driving circuit scans a display frame with a frame cycle and selects the plurality of the vertical scan lines sequentially, and wherein the horizontal driving circuit synchronizes with the scan of the frame cycle and writes the image signals to the pixels on the selected lines through the switches; an illumination unit configured to illuminate the liquid crystal display panel according to a plurality of divided luminescent regions along the vertical scan lines; and an inverter circuit configured to illuminate the luminescent regions successively along the vertical scan lines while receiving and delaying the vertical synchronizing signal outputted from the liquid crystal display control unit synchronizing with the scan of the vertical scan lines, wherein the inverter circuit comprises: a first turn-on timing circuit corresponding to a first luminescent region; and a plurality of second turn-on timing circuits and a plurality of turn-off timing circuits arranged to be connected in series and respectively corresponding to the second and the subsequent luminescent regions.
