Guangfeng Technology obtained invention patent authorization:

According to Qichacha data, Guangfeng Technology (688007) has newly obtained an invention patent authorization. The patent is called "LED display", the patent application number is CN201811137350.7, and the authorization date is April 5, 2024.

Patent summary: An LED display screen, including: an LED array, including a plurality of LED light-emitting units, and the plurality of LED light-emitting units are arranged on a substrate; a diffusion film, arranged on the light exit side of the LED array; a matrix light shielding frame, arranged between the LED array and the diffusion film, including a hollow grid array, the hollow grid array including a plurality of hollow grids, the hollow grid and LEDs The light-emitting units correspond one to one, and the projection of the hollow grid on the substrate surrounds its corresponding LED light-emitting unit; and the polarizer is arranged on the light path through which the light emitted by the LED array passes, and includes alternately arranged first polarization zones and second polarization zones. The light emitted by the LED array passes through the first polarization zone to form the first polarized light, and passes through the second polarization zone to form the second polarized light. The present invention disposes a matrix light shielding frame corresponding to the LED array on the optical path through which the light emitted by the LED array passes, so that the light emitted by the LED array is limited to the pixel unit and avoids mutual interference of light from adjacent LED light-emitting units.
