Abstract: Provided are a display screen and a curvature adjustment mechanism. The display screen includes a curvature adjustment mechanism, the curvature adjustment mechanism includes a first unit, a first slider, a second slider and a second unit, the first slider and the second slider are connected to the first unit; the second unit is provided with a first arcuate groove and a second arcuate groove, centers of the first arcuate groove and the second arcuate groove do not overlap; the first slider is able to slide in the first arcuate groove, and the second slider is able to slide in the second arcuate groove. The sliding of the first unit and the second unit is limited by using double arcuate grooves, the problem a display screen is not in an ideal curvature when the curvature of the display screen is adjusted by using a single arcuate groove can be solved.

Abstract: Embodiments of the present disclosure provide an LED light string, an LED light board, and an LED display. In the embodiments of the present disclosure, a first signal input port and a second signal output port of the LED bead are electrically connected directly to form a first breakpoint continuation line, to ensure that data signals can still be transmitted to the next LED bead even if the LED driver chip does not work. A second signal output port and a second signal input port of a first LED bead and a second LED bead with at least two LED beads therebetween are electrically connected to form a second breakpoint continuation line, so that data signals can still be transmitted to the second LED bead and subsequent LED beads, even if a plurality of consecutive LED beads fail to work.

Abstract: The present invention discloses a novel LED display screen. Equipped with a high power LED lamp and combining a high power lamp with a display screen. The LED display screen comprises a display module, a mounting framework, and a power distribution control box, characterized in that: said LED display module is equipped with a high power module. The display module and the power distribution control box are installed on a metal framework to form a display block. The power distribution control box is internally equipped with a drive power source, a signal receiving card, a signal transferring plate, a quick connector, etc. The mounting framework is equipped with a high-efficiency connector for quick coupling during installation of the display screen. The display screen in this scheme has a simple structure and a gorgeous display effect, is light, and is quickly and conveniently installed.
