Description

technical field

[0001] The present invention relates to the field of display technology, in particular, to a pixel structure with capacitance. Background technique

[0002] With the advancement of optoelectronic and semiconductor technologies, it drives the vigorous development of flat panel displays. Among many flat-panel displays, liquid crystal displays have become the mainstream in the market because of their superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. At present, liquid crystal displays usually have a wide viewing angle when displaying images, so as to meet the needs of multiple users viewing the same display device at the same time. However, the phenomenon of color washout in displays with wide viewing angles is also criticized by people. In order to solve the problem of color shift, the design of the pixel structure in the prior art reduces the aperture ratio of the di...
