The fast response Fresnel liquid crystal lens with multiple electrodes structure had been proposed and optimized. The multi electrodes in the new Fresnel LC lens were placed at both inner surfaces of LC cell. By supplying specific operating voltages on each electrode, the optimized Fresnel LC lens was closed to the ideal Fresnel lens. The experiment results indicated that the Fresnel LC lens not only performed fast switching rate without over-drive method, but also had the advantage of low operating voltage. Furthermore, by using overdriving method, the response time could be further reduced but just need 15volts in a short time. It meant that a fast switching between 2D and 3D image display could be obtained by switching Fresnel LC lens on and off. In the end, the fast switching display was also demonstrated.

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 (similar to 0.2 s), but also had the benefit of low driving voltage (similar to 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.
