Description

Technical Field

[0001] The invention belongs to the field of LED display screens, in particular to a fast-assembled LED display screen. Background Art

[0002] Nowadays, with the rapid development of the display market, foldable LED display screens have become one of the hottest products in the industry, especially in the outdoor media, advertising, outdoor SMD, special-shaped screen and other markets. They have performed very well and can give the public a great visual enjoyment. Foldable LED display screens are composed of circuit boards, plastic bottom shells and masks. Different from fixed LED display screens with steel frame structures, foldable LED display screens can be quickly unfolded and assembled when in use, and can be folded back in time when not in use, which is suitable for short-term temporary use.

[0003] When the foldable LED display is in operation, stability and safety are particularly important.
