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.
A multiview autostereoscopic LCD display with a localized 2D/3D switching function is developed based on the
actively switchable parallax barrier technology. This switchable barrier comprises of an electro-optically switchable
liquid crystal (LC) and a microretarder. Polymer dispersed liquid crystal (PDLC) with switchable clear and diffusing
states and twisted nematic liquid crystal (TNLC) with polarization switching function are used as switching devices. The
microretarder is prepared by self-developed multibeam laser scanning process, which is clean, friendly to the
environment, and easy for scale up and mass production. The influence factors on the image qualities of 3D displays
based on LCD panel technology are analyzed and discussed. Some solutions have proposed to solve the commercial
application issues.
Different fabrication methods, such as chemical process, laser heating method, etc., can be used to make
micro-retarder plates. In this paper, a CO2 laser scanning system is applied to produce a serious of line patterns on
the commercial compensator (or the retarder film, such as PC film, PVA film, or Arton film, etc.) to make
micro-retarder plates, which are important optical components in stereoscopic 3D displays. Our study is focused
on the development of high quality fabrication method, for example, the relationship of a well-defined stripe
boundary with the CO2 laser process under single beam or multiple beams. The laser scanning system in this paper
is installed with an orthogonal pair of precise translation stages, a steadily controlled laser power output, and an
adjustable spot-size optical head to make patterns of micro-retarder plates for stereo-LCTVs up to 42 inches.
