Patent ID: 8872170

Claim:
An image display system, comprising: an organic electroluminescent device, comprising: a substrate; a first electrode formed on the substrate; a first emitting layer formed on the first electrode, wherein the first emitting layer emits a first color of light, and a second color of light; a first hole injection layer and a first a hole transport layer disposed between the first electrode and the first emitting layer, wherein the thickness of the first hole injection layer and the first a hole transport layer is of between 650˜850 Å, or 1750˜1950 Å; a second electrode formed on the first emitting layer, wherein the second color of light emitted by the first emitting layer generates a first standing wave within the organic electroluminescent device, and the first emitting layer is disposed at an antinode of the first standing wave, such that the intensity of the second color of light is enhanced, and the second color of light is mixed with the first color of light to produce a white emission.
