Abstract
This present invention provides a flexible LED display by utilizing flexible wirings and the locations of the conductive pins on the bottom side of each single color LEDs or full color LEDs to make each of the single color LEDs or full color LEDs mount on each pixel defined by the flexible wires formed on the transparent flexible substrate, and this flexible LED display which characterizes in separating the wirings crossing over with each other by a so-called bridge technology and utilizing a single-layered substrate to save costs of processes and materials.
