Organic light-emitting diode display device and manufacturing method thereof, and organic light-emitting diode display
The present invention provides an OLED display device and a manufacturing method thereof, and an OLED display. The OLED display device comprises a substrate, and a color conversion layer and a blue light emitting layer are stacked sequentially on the substrate; the color conversion layer comprises red light conversion units, green light conversion units, and opening units which are arranged separately; the red light conversion unit and the green light conversion unit are both film layers made of an organometallic halide perovskite material. The red light conversion unit and the green light conversion unit absorb blue light emitted from the blue light emitting layer and convert the blue light into red light and green light, respectively, and the opening unit transmits the blue light, so that the color conversion layer can output color light with high saturation to achieve color display.
