Abstract

A sub-pixel circuit, display panel and driving method of the display panel are provided. The display panel has a plurality of data lines, scan lines and sub-pixel circuits. At least one of the sub-pixel circuits is electrically coupled to one data line and three scan lines. The sub-pixel circuit determines whether to receive data from the coupled data line or not according to scan signals transmitted on the coupled three scan lines, and controls transmittance itself accordingly. Specifically, the scan signals transmitted on the coupled three scan lines are different from each other.

Description

technical field [0001] The present invention relates to a display pixel circuit and a display panel using the same, and in particular to a display pixel circuit and a display panel using the same to reduce the color washout phenomenon of side viewing angles. 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 switching l...
