Abstract

The invention provides a light control plate and an LED display screen. The light control plate comprises a dielectric substrate and image sensing layers arranged on the dielectric substrate, whereina light control sensing circuit is arranged on one face of the dielectric substrate, multiple pixel lamps which are distributed at intervals are arranged on the face, deviating from the light controlsensing circuit, of the dielectric substrate, and the image sensing layers are arranged in gaps formed by the pixel lamps, and used for sending image signals and transmitting the image signals to thelight control sensing circuit to control the pixel lamps. According to the light control plate and the LED display screen, the size of the light control plate can be free of limitation while the lightcontrol display function is achieved, and the light control plate can be applied to the LED display screen of the large size.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of light control display, and in particular relate to a light control panel and an LED display screen. Background technique [0002] With the continuous development of LED display technology, capacitive touch technology is also widely used on LED displays of various electronic products, realizing the intelligent light control function of electronic products, and greatly improving the usability of electronic products. [0003] However, the capacitive touch technology in the prior art needs to use plexiglass as the touch layer, and when the size of the plexiglass exceeds a certain range, various physical problems are likely to occur, such as breakage and poor realistic effects. Therefore, the capacitive touch technology of the prior art can only be applied to small-sized display screens, while conference display, TV station display, exhibition display and other occasions usually requi...
