Description

Technical Field

[0001] The utility model relates to the technical field of display screen protection devices, in particular to an LED display screen protection device. Background Art

[0002] LED display is a new type of information display media, which is used to display various information such as text, graphics, images, animations, market conditions, videos, and video signals.

[0003] LED display screens are mainly composed of screen frames, screen glass, LED tube cores and power supply systems. They are mainly based on the light-emitting principle of semiconductor light-emitting diodes. When current passes through semiconductor light-emitting diodes, electrons and holes recombine in the semiconductor and release energy. This energy is expressed in the form of light, thereby achieving light emission. The control system of the display screen converts the video signal into appropriate drive signals, which then drive the LED light-emitting diodes to emit light in a specific pattern, thereby displaying images or text.

[0004] The existing LED display screen is usually exposed to the outside world and is easily scratched or hit by foreign objects, which may damage the electronic display screen and reduce the service life of the display screen. Therefore, a LED display screen protection device is proposed to solve the above problems. Utility Model Content

When the display screen is squeezed or hit by foreign objects, the force bar will be bent by the force, thereby pulling the movable rod to move, so that the movable electrode ring will also move. At this time, the spring is compressed by the force. When the movable electrode ring moves to contact the fixed electrode ring on the fixed ring, the light bar is energized and becomes brighter, thereby being able to promptly remind personnel that the display screen is squeezed or hit by foreign objects, so that corresponding countermeasures can be taken in time, and the protective film can help reduce the impact force, thereby avoiding damage to the display screen.

[0008] Preferably, two fluorescent strips are fixedly connected to the stress strip, and the two fluorescent strips are respectively located on both sides of the luminous strip. When the device is used, by setting the fluorescent strips, brighter light can be reflected when the luminous light of the luminous strip is felt, thereby attracting more people's attention.

[0009] Preferably, the bottom end of the protective film is fixedly connected to the two installation boxes at the lowest end with a fixing plate, and a plurality of suction cups are mounted on the fixing plate. When the device is used, the suction cups are provided to facilitate fixing the protective film on the display screen.
