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: 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: A new transparent-charge-injection-layer consisting of LiF/Al/Al-doped-SiO has been developed as (i) a cathode for top emitting organic light-emitting diodes (TOLEDs) and as (ii) a buffer layer against damages induced by energetic ions generated during deposition of other functional thin films by sputtering, or plasma-enhanced chemical vapor deposition. A luminance of 1900 cd/m 2 and a current efficiency of 4 cd/A have been achieved in a simple testing device structure of ITO/TPD (60 nm)/Alq 3 (40 nm)/LiF (0.5 nm)Al (3 nm)/Al-doped-SiO (30 nm). A thickness of 30 nm of Al-doped SiO is also found to protect organic layers from ITO sputtering damage.

Abstract: An apparatus for enhancing contrast in a flat panel display is provided. O ne embodiment includes a electroluminescent display having a front electrode, a n electroluminescent layer, an optical interference member, and reflective rea r electrode. The optical interference member is made from a semi-absorbing material, and the actual material, its thickness, "n" value, and "k" value are all so chosen such that ambient light incident upon the display is substantially reduced by destructive interference.

Abstract: An electrode for use in LCDs or other applications where a dark appearance of the electrode is desired. The electrode consists of a multi-layer structure that has a combination of optical properties which reduce light incident on the electrode. The electrode materials are also chosen to be conductive of electricity.
