Abstract

The present invention discloses a pixel structure which comprises a grid electrode, a resource electrode, a first drain electrode, a second drain electrode, a third drain electrode, a first pixel electrode, a second pixel electrode, a scanning beam and a data wire; wherein, the grid electrode, the source electrode and the first electrode form a first film transistor; the grid electrode, the sourceelectrode and the second drain electrode form a second film transistor; the grid electrode, the second drain electrode and the third drain electrode form a sub-film transistor. Moreover, the first pixel electrode is connected with the first drain electrode, and the second drain electrode extends between the second pixel electrode and a base panel to form a capacitor coupling electrode. In addition, the second pixel electrode is connected with the third drain electrode of the sub-film transistor; the scanning beam is arranged on the base panel, and is connected with the grid electrode; the data wire is connected with the source electrode. The pixel structure of the present invention can effectively avoid the phenomenon of remaining images on a display picture. The pixel structure has favorable display quality.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a pixel structure capable of improving display quality. Background technique [0002] The multimedia technology in today's society is quite developed, mostly benefiting from the progress of semiconductor components and display devices. As far as displays are concerned, liquid crystal displays with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. In order to improve the display quality of liquid crystal displays, various liquid crystal displays with wide viewing angles have been developed on the market, such as in-plane switching (IPS) liquid crystal displays and marginal field switching (IPS) liquid crystal displays. fringe field switching) liquid crystal display and multi-domain vertically aligned (multi-domain vertically aligned, MVA) liquid crystal...
