Outdoor shockproof LED display screen

Abstract

The invention relates to the technical field of screens, in particular to an outdoor shockproof LED display screen. The display screen comprises a frame, a base and a sunshade. A battery is arranged at the bottom of the base, a spring is arranged inside the base, and the frame is arranged on the top of the base. The frame and the base are fixedly connected by a support column, the support column and the spring are fixedly connected by a solid block, the bottom of the frame is provided with a ventilation window, and one side of the inner wall of the frame close to the ventilation window is provided with a dustproof net. The dustproof net and the frame are fixedly connected by a movable fixed seat, and the frame is internally provided with an LED display screen. The LED display screen and the frame are fixedly connected by a support frame, and the base surface of the LED display screen is provided with a tempered film. An exhaust fan is disposed on the back of the frame, and a motor boxis disposed on one side of the inner wall of the frame adjacent to the exhaust fan. The motor box is internally provided with a motor, and the motor and the exhaust fan are rotatably connected by a rotating shaft. The LED display screen is simple in structure, dustproof and shockproof and has a certain promotion effect.

Description

Technical field [0001] The invention relates to the technical field of screens, in particular to an outdoor shockproof LED display screen. Background technique [0002] LED, light-emitting diode, it is a kind of display mode by controlling semiconductor light-emitting diodes. It is a diode made of a compound of gallium and arsenic, phosphorus, nitrogen and indium. When electrons and holes are combined, it can radiate visible light, so it can be used To make light-emitting diodes, used as indicator lights in circuits and instruments, or form text or digital displays. Phosphor gallium 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. LED displays are generally used to display text, images, video, video signals and other information . [0003] Existing LED screens have some defects in the use process. For example, because the screen itself is a fragile item during us...

Problems solved by technology

[0003] Existing LED screens have some defects during use. For example, because the screen itself is a fragile item during use, it is very easy to be damaged by external impacts and cause economic losses, and some outdoor LED screens currently on the market do not have anti-corrosion protection. The dust and rainproof function greatly reduces the service life of the screen, so an outdoor shockproof LED display is needed to improve the above problems
