Introduction In recent years many types of electronic equipment have come into wide use in our lives. Especially mobile phones and personal computers have been widely used by many people and this fact causes the drastically change of our lives. In addition we can connect global networks using mobile phones and personal computers and we can get much information in a short time without moving. Nowadays several mobile networks are widely used such as Bluetooth ultra wideband ZigBEE and so on. Furthermore the global computer networks will be used unconsciously without thinking the connection in near future and many researchers demonstrated unique concepts of intuitive interface modules. Morrison et al. 2005 Wilson et al. 2007 Mignonneau et al. 2005 To realize an intuitive interface module between real the world and the global computer network we proposed the free space visible optical communication system utilizing organic light-emitting diodes OLEDs as a transceiver module and organic photo-diodes OPDs as a receiver module as shown in Fig. 1. In this system we can get information from the OLED by touching the emitting area and the emitting area of the OLED is large enough to connect without the precious alignment between the OLED and the OPD. Receiver module OPD Transceiver module OLED Fig. 1. Concept of the interactive visible optical communication system using the OLED and the OPD with the high response speed. 292 Organic Light Emitting Diode - Material Process and Devices By now several research groups demonstrated OLEDs and OPDs with the high response speed for the novel application of the optical communication and the response speed of more than Mbps has been achieved by optimizing the device structure.
