Indoor LED display screen with waterproof, dustproof and anti-static functions

Abstract

The invention relates to the technical field of LED display screens, and further discloses an indoor LED display screen with waterproof, dustproof and anti-static functions. The LED display screen comprises a base; supports are fixedly connected to the two sides of the top of the base; sliding grooves are formed in the two sides, close to each other, of each support; connecting plates are fixedlyconnected to the tops of the two supports, an air cylinder is fixedly installed at the top of the base, and an LED display screen frame is fixedly connected to the top of the air cylinder. A synchronous motor is started to enable the bevel gear II to drive the bevel gear I to rotate; the bevel gear I rotates to enable a threaded rod to drive a scraper fixedly connected with a sliding sleeve to rotate; therefore, the brush at the bottom of the scraper makes contact with the LED display screen frame to move left and right to remove dust on the LED display screen frame. The situation that due tothe fact that the LED display screen is used for a long time, too much dust is accumulated on the LED display screen frame, watching of the LED display screen is affected is avoided, and the situationthat too much dust is accumulated, the LED display screen is damaged, and use of the LED display screen is affected is also avoided.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an indoor LED display screen with waterproof, dustproof and antistatic functions. Background technique [0002] LED display is a display method by controlling semiconductor light-emitting diodes. Diodes made of gallium, arsenic, phosphorus, nitrogen, and indium compounds can radiate visible light when electrons and holes recombine, so they can be used to make Light-emitting diodes are used as indicator lights in circuits and instruments, or to form text or digital displays. Gallium-phosphorus-arsenide diodes emit red light, gallium-phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium-gallium-nitride diodes emit blue light. It is a display method that controls semiconductor light-emitting diodes. It is composed of multiple light-emitting diodes, and characters are displayed by turning on and off the lights. It is used to display vario...

Problems solved by technology

[0003] The existing LED display screens have relatively single functionality, and most of the LED display screens have the disadvantage of poor waterproof performance. When water is accidentally spilled on the LED display screen, touching the lines of the LED display screen may cause The short circuit of the LED display affects the use of the LED display, and most of the LED displays cannot be lifted, which is not very convenient to use in different environments, and does not have the functions of dust removal, anti-static and heat dissipation or the efficiency of heat dissipation methods The low speed is slow, and the effect of rapid cooling cannot be achieved. The low cooling efficiency will cause the internal temperature to be too high and damage the circuit, thereby affecting the service life of the LED display. Therefore, we propose an indoor LED with waterproof, dustproof and antistatic functions. display screen
