An organic light-emitting diode includes a transparent substrate (102), a transparent anode layer (104) disposed over the substrate, and a hole-transport layer (110) disposed over the anode layer. The diode also includes a light-emitting layer (120) disposed over the hole-transport layer, an electron-transport layer (130) disposed over the light-emitting layer, a cathode (205) disposed over the electron-transport layer and having a thickness selected so that light can pass through such cathode, and a light-absorbing layer (210) disposed over the cathode. A dielectric spacer layer (220) disposed over the light-absorbing layer and a conductive layer (230) disposed over the spacer layer and electrically connected to the cathode so that when a voltage is applied between the transparent anode and the cathode, the light-emitting layer produces light which passes directly through the hole-transport layer and the transparent anode and substrate. <IMAGE> |
