Abstract

The market of stereoscopic 3D TV grows up fast recently; however, for 3D TV really taking off, the interoperability of shutter glasses (SG) to view different TV sets must be solved, so we developed a measurement method with ideal shutter glasses (ISG) to separate time-sequential stereoscopic displays and SG. For measuring the crosstalk from time-sequential stereoscopic 3D displays, the influences from SG must be eliminated. The advantages are that the sources to crosstalk are distinguished, and the interoperability of SG is broadened. Hence, this paper proposed ideal shutter glasses, whose non-ideal properties are eliminated, as a platform to evaluate the crosstalk purely from the display. In the ISG method, the illuminance of the display was measured in time domain to analyze the system crosstalk SCT of the display. In this experiment, the ISG method was used to measure SCT with a high-speed-response illuminance meter. From the time-resolved illuminance signals, the slow time response of liquid crystal leading to SCT is visualized and quantified. Furthermore, an intriguing phenomenon that SCT measured through SG increases with shortening view distance was observed, and it may arise from LC leakage of the display and shutter leakage at large view angle. Thus, we measured how LC and shutter leakage depending on view angle and verified our argument. Besides, we used the ISG method to evaluate two displays.
