  • Publication number: 20030205971
    Abstract: An organic light-emitting diode device with a function of lateral light utilization. The device includes a transparent substrate, a first electrode, at least one organic light-emitting layer, a second electrode, and a wave-guide layer. In this case, the first electrode is formed on the transparent substrate, the organic light-emitting layer is formed on the first electrode, and the second electrode is formed on the organic light-emitting layer. The wave-guide layer is adjacent to the transparent substrate, and the wave-guide layer and the transparent substrate are located at the same layer in the organic light-emitting diode device. Furthermore, the invention also discloses a device with information display and back-light effect, which includes a light emitter and a wave-guide element. The wave-guide element transmits lateral light of the light-emitter outward, and the outputted lateral light is used as a light source.
