[0002] LED display is a flat panel display, composed of small LED module panels, used to display text, images, videos and other information. LED electronic display integrates microelectronics technology, computer technology and information processing. After searching, the Chinese patent publication number CN219916628U discloses a LED display brightness adjustment device, which rotates the worm by the staff, and stops rotating the worm when the counterweight is located inside the limit slot. Because the limit slot is provided with a magnet, the counterweight will be adsorbed. When the staff needs to adjust the brightness again, the worm can be located inside the other second card slot. This solves the problem that the brightness adjustment device of the traditional LED display is generally installed inside the LED display, and when it is used in a place with strong light, the display will be unclear and the screen display cannot be seen clearly.
