OLED display
The present invention provides an OLED display, comprising a substrate, a thin film transistor layer, a blue light emitting layer, a cover plate and a color conversion layer; wherein the color conversion layer comprises a plurality of red conversion units and green conversion units, and both materials of the red conversion units and the green conversion units are organic metal halide perovskite materials; the blue light emitted by the blue light OLED correspond to the red, the green and the blue sub pixel regions, and respectively converted into red light by the red conversion units to emit, converted into green light by the green conversion units to emit and emitted through the cover plate, directly to obtain the red, green, blue lights of high color saturation to realize the color display of the high color gamut.
