Abstract: An organic electroluminescence device with a low reflectivity includes organic electroluminescence layers, a transparent electrode, a thin metal electrode, a control layer, and an auxiliary electrode. The transparent electrode and the thin metal electrode are sited on both sides of the OEL layer, respectively, in order to excite it to emit light. The auxiliary electrode and the thin metal electrode are mostly separated by a control layer. Both the auxiliary electrode and the thin metal electrode are locally connected to maintain electrically connected. Therefore, the control layer is not necessarily conductive and its material selection is not restricted by the requirement of work function matching with adjacent layers. The disclosed OLED device with a low reflectivity does not require a circular polarizer. It can be used for both active-matrix and passive-matrix OLED displays. The reflection of ambient light can be largely reduced to increase the contrast of the display panel.

Abstract: A dual-screen organic electroluminescent display device is made by encapsulating two independent conventional organic electroluminescent displays inside two substrates to reduce its weight and thickness. Meanwhile, only one encapsulation step is carried out and encapsulation cost would be lower.

Abstract: A method of manufacturing a full-color organic electro-luminescent device on an indium-tin-oxide glass substrate. A pattern is formed on the indium-tin-oxide glass substrate by the photolithography and the etching process. The indium-tin-oxide glass substrate is cleaned. An insulation pad is formed over the indium-tin-oxide glass substrate. A low shadow mask and a high shadow mask are sequentially formed over the insulation pad by conducting dry film photo-resist processes. A hole-transport layer is formed over the indium-tin-oxide glass substrate by conducting a vapor-depositing process. Three vapor-depositing processes are simultaneously conducted to form red, green and blue light-emitting layers on the hole-transport layer using the low shadow mask and the high shadow mask as a barrier. An electron-transport layer and a metal layer are serially formed over the light-emitting layers by conducting vapor-depositing processes.
