Abstract
4-view parallax barrier is considered to be a practical way to solve the viewing zone issue of conventional 2-view parallax barrier. To realize a flickerless 4-view system that provides full display resolution to each view, quadruple timedivision multiplexing with a refresh rate of 240 Hz is necessary. Since 240 Hz displays are not easily available yet at this moment, extra efforts are needed to reduce flickers when executing under a possible lower refresh rate. In our last work, we have managed to realize a prototype with less flickers under 120 Hz by introducing 1-pixel aperture and involving anaglyph into quadruple time-division multiplexing, while either stripe noise or crosstalk noise stands out. In this paper, we introduce a new type of time-division multiplexing parallax barrier based on primary colors, where the barrier pattern is laid like “red-green-blue-black (RGBK)”. Unlike other existing methods, changing the order of the element pixels in the barrier pattern will make a difference in this system. Among the possible alignments, “RGBK” is considered to be able to show less crosstalk while “RBGK” may show less stripe noise. We carried out a psychophysical experiment and found some positive results as expected, which shows that this new type of time-division multiplexing barrier shows more balanced images with stripe noise and crosstalk controlled at a relatively lower level at the same time. © (2014) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
