Abstract
A display device can include an organic light emitting diode disposed in a first pixel configured to emit a first color light, a second pixel configured to emit a second color light, and a third pixel configured to emit a third color light, in which the organic light emitting diode emits the third color light; a first color-conversion layer disposed on the organic light emitting diode in the first pixel; and a second color-conversion layer disposed on the organic light emitting diode in the second pixel, in which the first color light and the second color light have a longer wavelength than the third color light.
Claims20
A display device, comprising:
- an organic light emitting diode disposed in a first pixel configured to emit a first color light, a second pixel configured to emit a second color light, and a third pixel configured to emit a third color light, wherein the organic light emitting diode emits the third color light;
- a first color-conversion layer disposed on the organic light emitting diode in the first pixel;
- and
- a second color-conversion layer disposed on the organic light emitting diode in the second pixel,
- wherein the first color light and the second color light have a longer wavelength than the third color light.
A display device, comprising:
- a blue organic light emitting diode disposed in a red pixel, a green pixel, and a blue pixel;
- a red color-conversion layer disposed on the blue organic light emitting diode in the red pixel, wherein the red color-conversion layer is configured to convert a blue light emitted from the blue organic light emitting diode into a red light;
- and
- a green color-conversion layer disposed on the blue organic light emitting diode in the green pixel, wherein the red color-conversion layer is configured to convert the blue light emitted from the blue organic light emitting diode into a green light.
A display device, comprising:
- a red pixel, a green pixel and a blue pixel;
- an organic light emitting diode including a blue organic emission layer configured to emit blue light, wherein the blue organic emission layer is disposed across the red, green and blue pixels;
- a red color-conversion layer disposed in the red pixel, the red color-conversion layer being configured to convert the blue light emitted from the blue organic emission layer into a red light;
- a green color-conversion layer disposed in the green pixel, the green color-conversion layer being configured to convert the blue light emitted from the blue organic emission layer into a green light;
- a transparent layer disposed in the blue pixel, the transparent layer being configured to pass the blue light emitted from the blue organic emission layer;
- a red color filter disposed in the red pixel;
- a green color filter disposed in the green pixel;
- a blue color filter disposed in the blue pixel;
- a first blue auxiliary color filter disposed between the red color-conversion layer and the blue organic emission layer in the red pixel;
- and
- a second blue auxiliary color filter disposed between the green color-conversion layer and the blue organic emission layer in the green pixel,
- wherein the red, green and blue pixels do not overlap with a polarizer.
