Abstract
A tiled light emitting diode (LED) display panel includes multiple flexible back plates arranged in tiles. Each flexible back plate has multiple through holes formed thereon. A pixel array is formed by multiple LEDs on the flexible back plates and collectively defines multiple pixels. Each pixel includes one LED and thin-film transistor (TFT) circuits disposed on a first side of a corresponding flexible back plate. A printed circuit board (PCB) is disposed at a second side of the flexible back plates. A third side of the PCB faces the second side of the flexible back plates and has multiple signal lines formed thereon. The LEDs and the TFT circuits of the pixels are electrically connected to the corresponding signal lines via multiple conductive structures formed in the through holes. A resistance per unit length of each flexible back plates is greater than a resistance per unit length of the PCB.
