Abstract We studied EL properties of organic light-emitting diodes using a semi-transparent metal anode and conductive polymer instead of indium tin oxide. A metal anode and conductive polymer are thought to be more suitable for flexible organic light-emitting diodes than indium tin oxide. We fabricated organic light-emitting diodes using a semi-transparent metal anode and conductive [...]

Abstract The commercial potential of small format, bright, low power consumptialn displays drives Kodak’s investment in thin-film, low-molecular weight organic electroluminescenl devices. The prototypical small-molecule organic light emitting diode (OLED) consists of a transparent hole-injecting electrode, indium tin oxide (ITO), followed in sequence by the hole-transport layer :N,N-bis( 1 -Naphthyl)-N,N’- bis(pheny1)benzidine (abbreviated NPB), the electron [...]

Abstract THE SUPERIORITY OF LIGHT-EMITting diodes (LEDs) over incandescent lights, due to long life expectancy, high tolerance to humidity, low power consumption, and minimal heat generation, is well supported. LEDs are used in message display boards, signal devices, and many other means of illumination. One important characteristic of LEDs is that they are semiconductor devices [...]

Abstract In this paper, we propose the wireless optical communication system with white colored LEDs for wireless home link (WHL). The white colored LEDs have a high power output and are regarded as lamps for the next generation. In the proposed system, this device is used for wireless home link. The proposed system is suitable [...]
