This application provides a LED display by utilizing flexible wires 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 a transparent substrate, and this LED display is characterized in separating the wires crossing with each other by a so-called bridge technology and utilizing a single-layered substrate to save costs of processes and materials.
