Full resolution auto-stereoscopic mobile display based on large scale uniform switchable liquid crystal micro-lens array

A full resolution auto-stereoscopic display for mobile phones is demonstrated. It is based on the sub-pixel level phase modulation of a switchable liquid crystal (LC) micro-lens array, which can be switched back to a conventional two-dimensional (2D) display. The full scale (4 inch) device aligns with the display panel perfectly at sub-pixel level and switches the entire display area uniformly with no distortion and no colour separation. The steering angle and crosstalk of the auto-stereoscopic display are evaluated by both simulation and experiment. The results show that satisfactory performance can be achieved by further reduction of the separation distance between the colour filter (CF) layer and the LC lens layer and close match it to the effective focal length of the LC lens.
