Reduction of Crosstalk in Time-Division Multiplexing Parallax Barrier with Low Power Consumption

This paper proposes a method to reduce stereoscopic crosstalk in time-division multiplexing parallax barrier system with reduced power consumption, where a fine slit pattern is generated by projecting LED striped light bars through a lenticular lens. When LEDs and a lenticular lens are used to generate a slit pattern, crosstalk level becomes higher than that of the system using a pair of LCD panels because the LED backlight does not fully synchronize with the update of image in the LCD panel. To overcome this problem, the lighting time of LED light bars is shortened, which enables reduction of crosstalk without lowering the ratio of luminance to power consumption.
