The Fraunhofer Institute is working towards OLED backligting for autostereoscopic 3D displays

The Fraunhofer Institute is working towards an OLED based backlight for auto-sterescopic 3D displays (that do not require glasses). The idea is to create a backlight that also compromises the stereo separation functionality, so the emission characteristics and therefore the illumination angle of the Liquid-Crystal (LC) modulator have to be a function of the user position relative to the display. This can be achieved by using a patterned OLED backlight. It consists of thin, individually controllable OLED stripes that are associated to the columns of the images, respectively the LC modulator that generates the image. The display also include a micro lens array. In principle, the OLED stripes are imaged into the pupil of the eyes, whereas the eyes are accommodated on the image generated by the LC-modulator.

Here's the Fraunhofer's brochure about this project.
