Light emission and detection is combined on one single chip by using OLED on CMOS technology. Such a chip has primarily been developed for optocouplers or photo-electric barriers, but it offers interesting possibilities for other fields. A new optical concept of an inverse confocal sensor based on bidirectional OLED Display will be presented.en621620conference paper
