Abstract

An exemplary pixel circuit and a flat display panel using the same are provided. The pixel circuit includes three sub-electrode control circuits. The sub-electrode control circuits are controlled by two scan lines to receive data transmitted from two data lines. One of the three sub-electrode control circuits adjusts stored data by charge sharing. Accordingly, a display control of the pixel circuit is achieved by the three sub-electrode control circuits.

Description

technical field [0001] The present invention relates to a display pixel circuit and a flat display panel using the same, and in particular to a display pixel circuit and a flat display panel using the same to reduce the phenomenon of side viewing angle color washout. Background technique [0002] Liquid crystal display is a kind of flat-panel display widely used at present. According to the driving method, liquid crystal displays can be roughly divided into twisted nematic (TN) liquid crystal displays, vertical alignment (Vertical Alignment, VA) liquid crystal displays, and in-plane switching liquid crystal (In Plane Switching, IPS) Three types of LCD monitors. [0003] Twisted nematic liquid crystal display is the earliest liquid crystal display developed, which has the advantages of low cost and fast response. However, the viewing angle of the twisted nematic liquid crystal display is narrow. In contrast, the vertically aligned liquid crystal display and the in-plane sw...
