Rigorous Analysis of an Electric-field-driven Liquid Crystal Lens for 3D Displays

초록

We numerically analyzed the optical performance of an electric field driven liquid crystal (ELC) lens adopted by 3D-LCDs through rigorous ray tracing. For the calculation, we first obtain the director distribution profile of liquid crystals using the Erickson-Leslie motional equation, and then calculate the transmission of light through the ELC lens using the extended Jones matrix method. The simulation was carried out for a 9 view 3D-LCD at 17.1 wide, where the ELC lens was slanted to achieve natural stereoscopic images. The results show that each view exists separately according to the viewing position at an optimum viewing distance of 80 . It is expected that the present simulation method provides optimum design conditions for obtaining natural 3D images by rigorously analyzing the optical functionalities of an ELC lens.
