Dual Direction Overdriving Method for Accelerating 2D/3D Switching Time of Liquid Crystal Lens on Auto-Stereoscopic Display

Abstract

In this paper, we investigate the dual direction overdriving method to accelerate both the 3D-on and 3D-off time of the lenticular liquid crystal (LC) lens. The experimental results indicated that the response time (tau(3D-on) and tau(3D-off)) was successfully improved for a factor of 4 as a thick (60 mu m cell gap) LC lens. The LC lens was also implemented on an auto-stereoscopic display to yield fast 2D/3D switching ability.
