Abstract

The embodiment of the present disclosure provides an LED light string, an LED light board, and an LED display. In the embodiments of the present disclosure, a first signal input port (DI) and a second signal output port (FDO) of the LED bead (100) 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 (FDO) and a second signal input port (FDI) 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. Furthermore, power is supplied in a serial power supply way, to reduce power consumption; furthermore, power is supplied in a hybrid serial-parallel power supply way, to address the issue of power outages in subsequent LED beads caused by malfunction of some LED bead and improve the reliability of the LED display.
