A two-dimensional/three-dimensional (2D/3D) display system is presented based on a twisted-nematic cell integrated polymeric microlens array. This device structure has the advantages of fast response time and low operation voltage. The crosstalk of the system is analyzed in detail and two approaches are proposed to reduce the crosstalk: a double lens system and the prism approach. Illuminance distribution analysis proves these two approaches can dramatically reduce crosstalk, thus improving image quality. © 2014 Optical Society of America. Source

A photoalignment technique used in preparation of fringe-field-switching (FFS) mode cells is presented. The azimuthal anchoring energy (AAE) of photoalignment is controllable by tuning the UV exposure and if the value of AAE is as strong as that of the rubbing method. The electro-optical properties of FFS cells are optimized with different electrode configurations and high quality dark states of various types of cells are achieved to create the high contrast ratio. The great thermal stability shown after applying voltage and heat confirms that photoalignment is suitable for FFS mode applications. © 2015 IOP Publishing Ltd. Source

A concept of universal crosstalk index for stereoscopic 3D display was proposed. Conventional crosstalk of shutter glasses 3D could be transferred to the new crosstalk index that could be comparable with the crosstalk index of patterned retarder 3D. The new crosstalk index was also investigated by human perceptive experiment. Source
