Problems solved by technology

[0009] However, using this method will double the number of data lines in the effective display area compared to common liquid crystal display devices
Increasing the wiring of the effective display area will put forward higher requirements for the design of the panel, and will reduce the effective display area, reduce the aperture ratio, reduce the brightness of the display device, and increase power consumption

Abstract

The present invention provides a field sequence liquid crystal display device and driving method thereof. The LCD device contains a liquid crystal panel, a back light source, a scan driver and a data driver, wherein the liquid crystal panel is divided into a plurality of areas, each area contains a plurality of scan lines, each area meanwhile respectively scans and controls pixel rows in every area; in each scan period, at least one pixel row of the upper and lower areas are scaned and controlled at the same time, and in the scan period, the image data are respectively transmitted to at least one pixel row of the upper and lower areas. The present invention can provide sufficient conducting time for every row transistor gate, and cut short scanning time of the entire TFT panel, which is propitious to ensure opening rate of the panel, can realize high-contrast and high brightness of the display panel, and provides furthermore wide prospect for the development of the LCD device.

Description

【Technical field】 [0001] The present invention relates to a field sequential liquid crystal display device and a driving method thereof, in particular to a field sequential liquid crystal display device and a driving method thereof which simultaneously scan and control corresponding pixel rows in multiple regions. 【Background technique】 [0002] A Field-Sequential Color Liquid Crystal display (FSC-LCD) is a display device with many advantages. The display device uses an inverter to drive red, green and blue (R, G, B) backlights to illuminate the entire panel sequentially, that is, to sequentially illuminate red, green and blue (R, G) on the same pixel. , B) The three kinds of light make the eyes produce an afterimage effect and make the three colors mix, as if they are continuously illuminated. Compared with the conventional liquid crystal display device, the field sequential liquid crystal display device does not need expensive color filters (color filter), which can reduc...
