Abstract
Ambient light inside viewing field of shutter-glasses 3DTV system can cause perceivable flicker due to high brightness of the light source. Omitting front polarizer of shutter glasses can be a solution for improving ambient light flicker, but it makes noticeable ghosting whenever 3D viewers tilt their heads. In this paper, we propose the new flicker-free shutter glasses compensated for viewers head tilt using tilt sensor. The crosstalk level, inserted by the shutter is below 1.6% within the tilt angle range from 0 to ±50°.
