Abstract-The crosstalk is always an issue for 3D displays. In this paper, we proposed a digital image processing method that could further reduce the optical crosstalk in 3D displays. Unlike the previous method, the proposed method-multi-zone digital crosstalk reduction method (MZ-DCR)-is not only based on the software approach, but also on the pixel structure of the 3D displays. In this paper, a patterned retarder 3D display with 2D1G panel was used to demonstrate the improvement of MZ-DCR method. a head tracking system was implemented to further enlarge the viewing angle.Index Terms-Crosstalk suppression, image processing, patterned retarder 3D display, 3D display.

“…Without a proper adjustment of this distance patterned retarder, stereoscopic displays will not have such a large vertical viewing angle anymore. A few studies have been dedicated to the calculation of crosstalk for patterned retarder‐based 3D‐displays. In Tanabe et al ., guidelines are given for designing the patterned retarder for a given 2D‐display.…”

“…In Tanabe et al ., guidelines are given for designing the patterned retarder for a given 2D‐display. In Hong et al ., and Ma and Chang, a measure for the crosstalk is obtained using a simplified pixel geometry only. Our aim was to develop a more accurate simulation model using ray‐tracing.…”

Front glass thickness requirements for high resolution polarized stereoscopic displays: A simulation platform

et al. 2016

The tendency of the display market is towards displays with higher resolutions. Therefore, patterned retarder‐based stereoscopic displays require smaller front glass thickness to maintain good vertical viewing angle and limited crosstalk. To properly design these stereoscopic displays and quantify these requirements, we developed a simulation platform to predict radiance, polarization profile, and crosstalk over viewing angles and over wavelengths. Tunable parameters such as the distance between the pixels and the patterned retarder, and the optical properties of the patterned retarder are included. The simulation platform has been validated by comparing outcomes of simulations with measurements. We predict crosstalk accounting for both the human eye field of view and the diameter of the pupil. We found that to obtain a vertical viewing angle of at least ± 30° and crosstalk of at most 0.11 for a display with a pixel pitch beyond 0.27 mm, the display should include black absorbers, and the thickness of the front glass should be at most 0.5 mm. For higher resolution displays (pixel pitch no more than 0.21 mm), a front glass thickness at most 0.15 mm is required to produce a vertical viewing angle beyond ± 14° and a minimum viewing distance of 0.3 m.
