Superzone Fresnel Liquid Crystal Lens for Temporal Scanning Auto-Stereoscopic Display

The fast response superzone Fresnel liquid crystal (LC) lens with multiple transparent electrodes was proposed for temporal scanning auto-stereoscopic display. The experimental results indicated that the superzone Fresnel LC lens not only performed fast switching time (~ 0.2 s), but also had the benefit of low driving voltage (~ 5 V rms ). A 4-inch 2D/3D switchable auto-stereoscopic display with superzone Fresnel LC lens was further demonstrated. Finally, by driving the multiple electrodes alternatively, the superzone Fresnel LC lens array could be moved on horizontal direction for increasing the resolution of auto-stereoscopic display.
