Description

Technical Field

[0002] With the advancement of screen display technology and the continuous enrichment of consumer demand, the requirements for screen display effects are getting higher and higher. At present, LED displays on the market can be divided into static scanning and dynamic scanning displays according to different driving methods. In dynamic scanning displays, traditional technology usually uses display control chips to implement the line scanning process of dynamic displays. There will be parasitic capacitance in the process of driving each line of scanning line to turn on. The parasitic capacitance will release the charge during the line scanning process, which will cause the display screen to have a smear phenomenon, greatly affecting the display quality of the display screen, resulting in unclear images on the display screen and high power consumption of the display screen line scanning; and the higher the line scanning frequency of the dynamic display screen, the more serious the smear phenomenon of the display screen, and the worse the visual experience of the viewer.
