Abstract
An LED display screen with protective devices is disclosed. Two adjacent display screen boxes are respectively provided with a first protective device and a second protective device which are retractable; first protective device and second protective device are correspondingly arranged; first protective device is linked with second protective device so that the two adjacent display screen boxes are spliced; and a portion of first protective device and second protective device respectively protrude from the display screen boxes when the two adjacent display screen boxes are not spliced. When the display screen boxes are not spliced, the protruding portions of protective devices may protect the sides of display screen boxes to prevent damage to the display screen boxes caused by collision, etc. Because the protective devices are retractable, they can retract without affecting the splicing between display screen boxes when the display screen boxes are spliced.
