OLED (organic light-emitting diode) display unit and OLED spliced display screen with same

The invention relates to an OLED (organic light-emitting diode) display technology and specifically relates to an OLED display unit and an OLED spliced display screen with the same. The OLED display unit comprises a substrate and an OLED module arranged on the front surface of the substrate, wherein a packaging layer is arranged on the periphery and the front surface of the OLED module, conductive films are plated on the front surface and the peripheral side walls of the substrate, the conductive film on any one side wall of the substrate is connected with an anode in the OLED module, the conductive film on another side wall of the substrate is connected with a cathode of the OLED module, an anode leading wire and a cathode leading wire are respectively led out of the conductive films on another two side walls of the substrate and connected with an external circuit, and the two side walls of the substrate are externally connected with binding regions. According to the OLED display unit disclosed by the invention, the binding regions of an OLED panel are transferred onto the side walls of the substrate through a packaging surface of the OLED module, so that a non-luminous side frame region of a device is reduced, and the splicing effect of the OLED spliced display screen is optimized.
