Time-sequential autostereoscopic OLED display with segmented scanning parallax barrier

摘要

We have developed and prototyped 14" WXGA full resolution 2D-3D autostereoscopic OLED display with fast switching parallax barrier, capable of scanning in quasi-synchronism with line-by-line image update. The parallax barrier is formed by fast directly driven TN liquid crystal panel, placed between crossed polarizers. Scanning capability has been added to LCD based parallax barrier in order to reduce crosstalk that appears because of scan and hold operation of OLED display. The crosstalk level in "sweet points" of the viewing zone is measured below 5%. Image brightness in 3D mode comprises 45% of the brightness in 2D mode. To reduce image flicker in 3D mode OLED panel is driven at a frame frequency 120 Hz.
