Abstract

Disclosed is a pixel circuit having a first sub-pixel and a second sub-pixel. The first sub-pixel has a first transistor and a first capacitor unit, and the second sub-pixel has a second transistor, a second capacitor unit and a voltage regulating circuit. Further, the first transistor and the second transistor each have a first terminal, a control terminal and a second terminal. The control terminal of the first transistor is electrically coupled to a scanning line, and the first capacitor unit is electrically coupled between the second terminal of the first transistor and a common electrode unit. In addition, the control terminal of the second transistor is electrically coupled to the scanning line, the second capacitor unit is electrically coupled between the second terminal of the second transistor and the common electrode unit, and the voltage regulating circuit is electrically coupled to the second terminal of the second transistor and the common electrode unit.

Description

[0001] 【Technical field】 [0002] The present invention relates to a liquid crystal display, and in particular to a pixel circuit of a liquid crystal display and a pixel voltage adjustment method thereof. [0003] 【Background technique】 [0004] A Liquid Crystal Display (LCD) is commonly used as a display device due to its ability to display high-quality images using a small amount of power. With the development of science and technology, various types of liquid crystal displays are gradually derived. Among them, vertically-aligned (VA) liquid crystal displays have the characteristics of fast response, so vertically-aligned liquid crystal displays are widely used in the industry. However, if the user views the vertical alignment liquid crystal display from the side, the user will see a severe color washout phenomenon at the side viewing angle. [0005] In order to improve the whitening phenomenon of the side viewing angle, the industry proposes a pixel circuit structure, which...
