Problems solved by technology

However, with the improvement of pixel resolution, the unit pixel area is gradually reduced, and the overlapping area between the common electrode and the pixel electrode is also reduced, resulting in a decrease in the storage capacitance of the pixel structure.
As a result, the pixel structure of high-resolution (Pixelperpitch; PPI) products will face the situation that the feedthrough voltage (V-feedthrougheffect) is too serious

Abstract

The invention relates to a pixel structure and a display panel. The pixel structure is arranged on a substrate and comprises a data line, a scanning line, an active component, a pixel electrode, a first common electrode and a second common electrode. The scanning line and the data line intersect; the active component is electrically connected with the data line and the scanning line; the pixel electrode is electrically connected with the active component; a first projection distance is formed between the pixel electrode and the data line; the first common electrode is disposed on the pixel electrode and overlaps the pixel electrode; the first common electrode comprises a plurality of openings for exposing the pixel electrode; the second common electrode is disposed under the pixel electrode, with the projection thereof overlapping the pixel electrode; a second projection distance is formed between the second common electrode and the data line; and the second projection distance is less than the first projection distance. The display panel with the pixel structure has better display quality and high-resolution products may have lower power consumption.

Description

technical field [0001] The present invention relates to a pixel structure and a display panel, and in particular to a high-resolution pixel structure and a display panel including the pixel structure. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanelDisplay) has been vigorously developed. Liquid crystal displays have replaced traditional cathode ray tube displays due to their advantages of low-voltage operation, no radiation scattering, light weight, and small size, and have become the mainstream of display products in recent years. However, liquid crystal displays still have the problem of limited viewing angles. At present, the technologies that can meet the requirement of wide viewing angle include twisted nematic (twistednematic, TN) liquid crystal plus wide viewing film (wideviewing film), in-plane switching (IPS) liquid crystal display, fringe fiel...
