Abstract

A pixel structure includes a scan line, a data line, a driving device, a first pixel electrode, an insulating layer and a second pixel electrode. The driving device is electrically connected to the scan line and the data line. The first pixel electrode is electrically connected to the driving device. The insulating layer covers the first pixel electrode. The second pixel electrode is disposed on the insulating layer. The second pixel electrode is electrically connected to the driving device and is not directly connected to or not contacted with the first pixel electrode.

Description

technical field

[0001] The present invention relates to a pixel structure and its driving method, and in particular to a pixel structure capable of reducing the color washout phenomenon of a display and its driving method. Background technique

[0002] Nowadays, the performance requirements for liquid crystal displays in the market are developed towards high contrast, fast response and wide viewing angle. Currently, the technologies that can meet the wide viewing angle requirements include Multi-domain Vertical Alignment (MVA), Multi-Domain Horizontal Alignment (MHA), etc. ), twisted nematic plus viewing angle expansion film (TN+film) and transverse electric field form (IPS). Although the liquid crystal display with the technologies listed above can achieve the purpose of wide viewing angle, there is still much room for improvement in the existing color washout phenomenon.

[0003] Generally speaking, the so-called color shift means that when the user watches the image disp...
