Problems solved by technology

However, this type of liquid crystal display device will appear color shift phenomenon when the viewing angle is large.
[0003] In order to solve the large viewing angle deviation phenomenon in the aforementioned vertical alignment mode liquid crystal display device, a design in which two gate lines are used to control the charging sequence of two sub-pixels is proposed in the known technology, and one sub-pixel is only fed through once. (feed through) the influence of the voltage drop, but the other sub-pixel is controlled by two gate lines and will have the influence of the feed through voltage drop twice
This will cause the feedthrough potentials of the two sub-pixels to be different, which will easily lead to signal errors, resulting in poor display effects

Abstract

The invention discloses a liquid crystal display device which comprises a data wire, a pixel, a first gate line, a second gate line, an additional electrode and an additional gate line. The pixel consists of a first sub-pixel and a second sub-pixel; the first gate line is used for determining whether the first sub-pixel is opened; the second gate line is used for determining whether the second sub-pixel is opened, wherein the first sub-pixel is electrically coupled with the data wire so as to receive signals provided by the data wire and the second sub-pixel is electrically coupled with the first sub-pixel by the additional electrode so as to receive the signals provided by the data wire through the first sub-pixel. The additional gate line goes across the additional electrode so as to form a compensation capacitor with the additional electrode.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to a liquid crystal display device capable of improving the color washout phenomenon that occurs when the viewing angle is large. Background technique [0002] Vertical alignment mode (Vertical Alignment Mode) liquid crystal display device is a wide viewing angle technology, because the liquid crystal display device of this mode displays black when no electric field is applied, so it is also called normally black (Normally Black) mode liquid crystal display device. However, the liquid crystal display device of this mode will have a color shift phenomenon when the viewing angle is large. [0003] In order to solve the large viewing angle deviation phenomenon in the aforementioned vertical alignment mode liquid crystal display device, a design in which two gate lines are used to control the charging sequence of two sub-pixels is proposed in the known technology, and one sub-pixe...
