Reduction of power consumption for autostereoscopic display based on time-division multiplexing parallax barrier

In this paper, we propose a time-division multiplexing parallax barrier system with reduced power consumption by using a lenticular lens to generate active barrier slits. In the conventional study, the ratio of luminance to power consumption is low because of the usage of two LCD panels with limited transmittance. In the proposed system, a fine slit pattern is generated by projecting LED striped light through a lenticular lens, where active change of slit pattern is realized by changing the positions of LED emission. We measure and confirm reduction of power consumption in the proposed method. We also compare the effects of time division on crosstalk in the conventional and the proposed methods.
