Claim:
1. A tiled organic light-emitting diode LED) display, comprising: one single-structure TFT driving backplane; an OLED front panel comprising multiple OLED front panel units tiled to each other, wherein the OLED front panel units include a transparent substrate, a first electrode layer, an organic material layer, and a second electrode layer that are sequentially arranged in a stacked manner; a conductive film coupling each of the OLED front panel units to the one TFT driving backplane; and a protection substrate disposed on a light-emitting side of the OLED panel, wherein the second electrode layer is electrically connected to a source or a drain of the TFT driving backplane by using the conductive film, and the second electrode layer is led out by using a first conducting contact layer, the source or the drain of the TFT driving backplane is led out by using a second conducting contact layer, the first conducting contact layer and the second conducting contact layer are joined to each other by the conductive film.
