Abstract
An OLED display device includes a substrate, an OLED layer located on the substrate, and a quantum dot package layer covering the OLED layer. The quantum dot package layer includes a quantum dot material. Blue light or white light emitting from the OLED layer excites the quantum dot material of the quantum dot package layer to emit light for color displaying with high color gamut.
Claims5
An Organic Light Emitting Diode (OLED) display device, comprising a substrate, an OLED layer located on the substrate, a quantum dot package layer located on the substrate and the OLED layer and covering the OLED layer, and a color filter located on the quantum dot package layer;
- wherein the OLED layer comprises a plurality of white light OLEDs, which are arranged in an array;
- the quantum dot package layer comprises a quantum dot material, which is distributed in a region of the quantum dot package layer located above and corresponding to the OLED layer;
- and
- the white light OLEDs emit white light from tops thereof to excite the quantum dot material in the quantum dot package layer to emit light;
- and
- wherein the OLED layer located on the substrate has surfaces exposed outside the substrate and the quantum dot package layer covers the surfaces of the OLED layer that are exposed outside the substrate so that the OLED layer is enclosed between the quantum dot package layer and the substrate.
