Abstract:
Study focuses on optimization of an edge-lit backlight module for a three-dimensional liquid  crystal mobile phone display. The module is designed with microstructures on the top and bottom surfaces of the light-guide plate to offer time-multiplexed projection of light into a viewer’s eyes. We simulated the module by optical software (TracePro) and liquid crystal software (LCDMaster 2D).  The results effectively eliminate the need for prism  sheets and satisfy three main performance metrics, namely a direction light-emission angle, uniformity of illumination, and crosstalk elimination.
