Abstract: An electroluminescent device having high-contrast and/or high-reliability is provided. The electroluminescent device comprises a pair of electrodes-at least one of which is transparent to electroluminescent light, and a phosphor layer which is disposed between the electrodes. The phosphor layer has a host crystal lattice, a first dopant and a second dopant. The first dopant cooperates with the host crystal lattice to cause light emission when a voltage is applied across the pair of electrodes, and the second dopant further distributes the first dopant in the host crystal lattice to increase light emission from the phosphor layer.

Abstract: An aspect of the invention provides an electroluminescent device that incorporates a partially-absorbing layer which is disposed in front of an emitting electroluminescent layer and reflective rear electrode. The thickness and material of the partially-absorbing layer cooperates with the thickness of the electroluminescent layer to cause at least some reduction in ambient incident of the display.

Abstract: The present invention provides an electroluminescent device having a dark layer for reducing at least a portion of ambient light incident on the display. In one bottom emitting device embodiment; the dark layer is placed between the emitting layer and a reflective rear cathode. The dark layer comprises a partially reflective layer, an absorptive-transmissive layer, and a reflective layer.

Abstract: An optical interference member is provided for use with active matrix or oth er patterned displays. In one embodiment, the optical interference members is configured to reduce incident ambient on the display through the use of thin film optical interference layers that are located on the display in locations not occupied by light emitting pixels or other light emitting means. In an active matrix display, the optical interference members can be coated upon the bus lines which connect to each of the transistors within the display, thereby presenting a black matrix whi ch surrounds each pixel and provides improved contrast enhancement.
