<jats:title>Abstract</jats:title><jats:p>Bi‐directional OLED based microdisplays offer interesting possibilities for new applications. Light emission and detection is included in one chip by using OLED‐on‐CMOS‐technology. Such device has been primary made for optocouplers or photoelectric barriers, but it offers interesting possibilities for other application fields, e.g. multimedia and metrology. A new optical concept of a 3‐D metrology sensor based on bi‐directional OLED microdisplay will be presented.</jats:p>
