Abstract
A display structure () comprises an emissive layer () and an excitation prevention layer (). The emissive layer includes a set of first color emitting areas () that emit a first color light in response to light that is generated by a first set of light emitting diodes (LEDs) () that are preferably organic. The excitation prevention layer is disposed at the front side of the emissive layer and includes a first set of excitation prevention filter areas (). In one embodiment, a first set of excitation prevention filter areas block a band of the light that is incident upon the emissive layer from the front of the display, wherein the blocked band of light is within an excitation band of the first set of LEDs.
