display device

Abstract

A display device comprising: a first pixel row including a first sub-pixel and a second sub-pixel arranged in a first direction; a second pixel row including a third sub-pixel and a fourth sub-pixel arranged in a first direction The sub-pixels are arranged in the second direction of the first pixel row; the gate wiring group includes a plurality of gate wirings; the source wiring group includes a plurality of source wirings; The video signal written in each sub-pixel of the 2-pixel row is supplied to each sub-pixel through a source wiring, and the display driving unit supplies a signal that makes adjacent source wirings do not change polarity within one frame period. The polarities of the video signals are opposite polarities, the video signals of the same polarity are written into the sub-pixels of the first pixel row, and the video signals of the same polarity are written into the sub-pixels of the second pixel row. And the polarity of the video signal written in the first pixel row is an image signal of opposite polarity.

Background technique [0004] In the case of a liquid crystal display device using an electric field controlled birefringence (ECB) mode, due to the relationship between the polarity of adjacent pixels and the grinding direction of the alignment film, the liquid crystal molecules are affected by an undesired transverse electric field, and in a part of the area Inconsistency (disclination) in the orientation of liquid crystal molecules occurs. Disconnection causes various display defects such as image sticking, blurring, and contrast drop when displaying an image, so it must be avoided. [0005] The most reliable method is to shield disclina...

Problems solved by technology

However, when row inversion driving is applied to the video signal whose polarity is inverted every one or more pixels to the same source wire, it is the same as applying the same source wire to the same source wire within one frame period. There is a problem of higher power consumption compared to the case of column inversion driving of polarity video signals
