 C3100: 3D active shutter glasses for cinemas (compatible XpanD 3D cinema glasses)Model: C3100Typical Features: 1. High brightness shutter technology2. Solid and durable Shape3. Replaceable battery increases lifetime4. Super low power consumption design for hundreds hours using5. Extended receiving angle6. Auto on/off7. Super Low power detection for hundreds hours standing-by8. compatible XpanD 3D cinema glasses, i.e. can be used in same cinemas as XpanD 3D cinema glasses.Product Features:1. High brightness shutter technology: adopt fast response and high transmittance LCD, support higher than 200fps and guarantee image brightness 2. High quality: solid, durable and flexible, replaceable battery extends lifetime, to reduce the maintenance cost of 3D digital cinema 3. Low power consumption:  adopt low power consumption chips and power saving circuit layout, thus the glasses maintain an average of 300hrs continuously working and one year standby lifespan. 4. Extended receiving angle: utilize extended IR receiving window of high filtration materials, to reduce environmental interference and ensure all-round receiving without black hole.  5. Auto on/off: utilize intelligent auto on/off to extend battery lifespan, start automatically once receiving IR signal, and turn into power saving mode in five minutes after IR signal disappeared.  6. Low power detection: built-in power detection function, The LCD lens will flash once a second when the 3D glasses are in low power mode, to indicate users that the battery needs replacing.   7. Rubber nose pad can be replaced to meet users of different nasals.Specifications: 1. Weight: 80g2. Shutter: High-speed liquid crystal style3. LCD refresh rate: 120 Hz4. Transmission: 39%5.
