Effects of Electric Field and Alignment on LC Lens for 2D/3D Switchable Display
We demonstrate a multi-electrode 2D/3D switchable display with electrically-controlled birefringence mode liquid crystal (LC) lenses. By applying a periodical electric field, the 2D/3D switchable display can form a gradual refractive-index (GRIN) distribution to generate 3D images. There are several factors that may affect the 3D optical characteristic of LC GRIN lens, such as cell gap, electric field distribution and alignment direction of the LC layer. The LC mode and optical property simulations were performed to analyze the effects of the different factors. We found that compare to the parallel alignment, vertical LC alignment direction to the electrodes may achieve less 3D crosstalk because the LC lens with parallel alignment direction to the electrodes leads to coexistence of ordinary and extraordinary lights, which degrades the LC lens effect. While considering the LC texture defect caused by electric field direction and LC alignment direction and the asymmetric driving voltage, the large cell gap LC lens with parallel LC alignment direction to the electrodes shows good performance for 3D display.
