3d shutter glass
3d active shutter glass for 3d ready dlp link projectors & 3dtvs (black
color) no emitter required, works with all dlp link 3d ready projectors
frequency: 96hz, 100hz, 120hz, and 144hzinbuilt rechargeable lithium battery
these active shutter 3d glasses that have been designed to work with 3d dlp
projectors. The reason for these glasses to have active shutter is that some active
shutter 3d systems usually require active shutter 3d glasses to work well. The 3d
glasses have a liquid crystal layer in each eye's glass that has the property of
becoming dense when voltage is applied, being otherwise transparent. These 3d
glasses are controlled by a timing signal that allows the glasses to alternately block
one eye, and then the other, in synchronization with the refresh rate of the screen.
