  • Optical projection screen and management system thereof
    Patent number: 10809605
    Abstract: An optical projection screen and a management system thereof are provided. The optical projection screen comprises an LED display module, a cooling module and an optical projection curtain. The optical projection curtain adheres to the LED display module with optical UV glue and is disposed on the light-emitting side of the LED display module. The cooling module is disposed on the backlight side of the LED display module and comprises a plurality of cooling assemblies distributed in different areas and used for cooling different areas of the LED display module. Each cooling assembly comprises a semiconductor refrigeration module, a temperature sensor and an intelligent switch. The intelligent switches control on-off of the semiconductor refrigeration modules according to the temperature detected by the temperature sensors. Multiple modules can be spliced to achieve large-screen display.
