Fraunhofer Institute’s latest prototype using bi-directional OLED display technology will be revealed the Smart Systems Integration 2011 Expo. The current model consists of a 0.6-inch 320 x 240 AMOLED panel with an integrated 160 x 120 CMOS camera.

Both are monochrome, with the AMOLED delivering more than 15,000 cd/m2 brightness. Interspersed between the AMOLED pixels are the CMOS photoreceptors, meaning the panel can both see and display objects simultaneously.

Fraunhofer has previously suggested that the bi-directional OLED panels could be used in futuristic wearable displays, like in the mockup below. However, it could also mean your cellphone screen could scan business cards (the OLED panel acting momentarily as a scanner light source). VGA and higher resolution displays and smaller chip sizes are currently under development.
