Abstract
An organic light emitting diode (OLED) panel includes a thin film transistor (TFT) array substrate, a plurality of OLED devices, and a plurality of isolator assemblies. The TFT array substrate includes a plurality of pixel regions, and the OLED devices disposed on locations corresponding to the pixel regions respectively. The OLED devices include an OLED layer. The isolator assemblies are configured to block the OLED layer of a white light-emitting device from extending to the OLED devices adjacent to the white light-emitting device. By arranging the isolator assemblies around the white light-emitting device, light generated by the white light-emitting device is prevented from leaking.
