Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a protective device for LED display screens. Background Art

[0002] LED displays are a new type of imaging electronic device that utilizes semiconductor light-emitting diodes (LEDs). They feature high brightness, wide viewing angles, and a long lifespan. LED displays are composed of tens to hundreds of thousands of evenly spaced semiconductor light-emitting diode pixels. These pixels can be made of various materials and colors to display text, graphics, images, animations, market information, videos, and recordings. LED displays can also be categorized into indoor and outdoor types based on the environment, and can be manufactured in various shapes, including spherical and spherical, to suit specific needs. They are primarily used for displaying text, images, and rendering effects, boasting vibrant colors and a high dynamic range.

[0003] Since the corners of the LED display screen are relatively fragile, the LED display screen is easily bumped during transportation, causing the LED display screen to be damaged, thus affecting the subsequent use of the LED display screen. Utility Model Content
