The present invention is applicable to the field of display technologies and provides a tiled OLED display, and the tiled OLED display includes an OLED front panel and a single-structure TFT driving backplane, where a protection substrate is disposed on a light-emitting side of the OLED front panel; the OLED front panel includes multiple OLED front panel units that are tiled to each other; and the OLED front panel unit is joined to the TFT driving backplane by using conductive film. In the present invention, by tiling the OLED front panel on the TFT backplane, production efficiency and a yield rate of the display are improved, thereby reducing a cost. By tiling the OLED front panel, a tiling gap is narrowed, thereby implementing seamless tiling. Compared with a traditional structure that uses an optical lens to eliminate a tiling gap, the yield rate of the tiled display is improved. By joining the OLED front panel to the TFT driving backplane by using the conductive film, a display aperture ratio is improved, and a problem that it is difficult to control alignment precision and stability is poor is overcome.
