Crosstalk modeling in circularly polarized stereoscopic LCDS
Crosstalk is the most critical artifact in stereoscopic 3D displays. Circularly polarized (CP) 3D LCDs with passive glasses has the issue of crosstalk especially when the viewer moves vertically away from the screen center. In this work, a new display model for CP LCD is proposed which considers both the intrinsic optical system including the polarizer and the wave retarder, and the vertical misalignment (VM) of light between the liquid crystal (LC) and the patterned retarder (PR) as the two major factors causing crosstalk in CP LCDs. The optical modeling for the display uses Mueller calculus and the characterization of VM is realized by the proposed user-calibration method. The display model is proved to be accurate by both measuring and subjective test in predicting the crosstalk resulted from different viewing scenarios. Additionally, we proposed considering image texture for the estimation of crosstalk perception. The proposed estimation is shown to be consistent with the viewer's observation.
