Time-multiplexed autostereoscopic display with content-defined 2D/3D mode selection

We have built a 17" 2D-3D time sequential LCD autostereoscopic display with SXGA resolution, which does not have any special means for 2D-3D switching. The display is capable of simultaneous displaying 2D and 3D graphics without deterioration of visual performance of 2D images at a frame rate up to 120 Hz. Left and right sets of viewing zones are formed by a combination of a patterned retarder and a lenticular lens array placed behind the LCD panel. Right and left sets of viewing zones are switchable by polarization switch in synchronism with displaying left and right images. Application of patterned retarder provides smooth light distribution without dark regions between left and right viewing zones. To reduce dynamic crosstalk caused by slow switching of LCD cells a combination of Rresponse Time Acceleration (RTA) and scanning backlight have been applied
