There are several studies on estimating crosstalk of 3D displays. Crosstalk is an important factor in determining image quality of stereoscopic display. In previous study, gray to gray crosstalk model has been modified. In this paper, we use six commercial stereoscopic displays including passive polarized glasses and active shutter glasses, both left and right eyes were measured by a luminance meter to verify the gray to gray crosstalk model and analyze the stability of the measurement data using our standard operating procedure (SOP). According to the SOP, we use simple statistical method to verify the repeatability of data. Experimental results indicate that our measurement system can be used to estimate the value of gray to gray crosstalk of stereoscopic display, the uncertainty below 0.8% for FPR display and 3% for shutter glasses display at 95% confidence level. These results, can be used as an important parameters in stereoscopic display visual quality, also can be used as a design feedback for engineer.
Many people believe that in the future, autostereoscopic 3D displays will become a mainstream display type.
Achievement of higher quality 3D images requires both higher panel resolution and more viewing zones. Consequently,
the transmission bandwidth of the 3D display systems involves enormous amounts of data transfer. We propose and
experimentally demonstrate a novel time-multiplexed autostereoscopic multi-view full resolution 3D display based on
the lenticular lens array in association with the control of the active dynamic LED backlight. The lenticular lenses of the
lens array optical system receive the light and deflect the light into each viewing zone in a time sequence. The crosstalk
under different observation scanning angles is showed, including the cases of 4-views field scanning. The crosstalk of
any view zones is about 5% respectively; the results are better than other 3D type.
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.
3D-FDTD is used to compute the electromagnetic response of various plasmonic nanostructures. Results of
computation and simulation are used to design the contact area of the photo-catalytic reactors. Novel nano-fabrication
techniques are developed to implement large surface area of plasmonic nanostructures for photo-catalytic reactors.
Measurement and analysis of the photo-catalytic process happened in the newly designed photo-chemical reactors clearly
demonstrate better efficiency of some photo-catalytic chemical process such as the decomposition of the Methyl Orange
to carbon dioxide and water.
