Crosstalk analysis in LCD stereoscopic displays with active shutter glasses
Improvement in the quality of Liquid Crystal Displays (LCD) triggers a significant surge in the 3DTV market. A large segment of the 3DTV market has adopted active shutter glasses (active 3DTV). In this system, crosstalk is an important factor that affects the viewing quality of active 3DTV. This paper proposes a mathematical model for crosstalk and analyses the temporal, spatial, LCD-based and liquid crystal shutter glasses (LCS)-based features of crosstalk in active 3DTV. Simulations of 120Hz active 3DTV under several scenarios are conducted and the result is compared with the measured crosstalk, verifying our model. Furthermore, the proposed model is used to analyze crosstalk for different parameters in both monitor and glasses and an effective method to reduce crosstalk is presented.
