3D Glasses Can They Have Universal Appeal

3D movies have been a great selling point for cinemas all around the world for many years now, as both a novelty and something not quite possible to recreate at any given time. The idea of characters looking like they are ready to come out of the screen and sit next to you is appealing in its own, slightly inexplicable way. Paying for a one-time experience at a cinema, with huge screen and large space around you is one thing, but would you actually use 3D glasses at home, watching movies on a much smaller TV screen or a laptop? Did technology get as far as making it a pleasure?


Many people have wondered why cinemas, with all the new technology available are still using the traditional, paper 3D glasses. The idea of wearing them at home can’t sound appealing once you realise that any change of position on the sofa would either mean not seeing the screen properly or the need to readjust the glasses all the time. The reason for cinemas using them is simple – cheap glasses can be easily replaced if they were stolen or broken. Since the passive glasses themselves are not that advanced, cinemas need to get a polarizing modulator and a silverized screen in order to maintain the polarization of the movie and properly show it to the viewers. And that technology is not cheap and definitely not easy to turn into a home-use device.


Now, at home 3D glasses are something very different. The most popular technique of bringing 3D display into home cinemas is the active-shutter technology which requires much more advanced glasses that are more expensive and for years were uncomfortable, bulky and fit to work with only one TV brand (the manufacturer would provide glasses to match the TV). XpanD is the company that has changed that, bringing us the “universal” 3D glasses that work with most major-brand 3D TV sets . Being a much lighter and more stylish solution than the glasses that manufacturers provided only a couple of years ago, XpanD glasses became a standard and now more and more TV manufacturers are working with XpanD to bring their technology to work with their screens. From a simple person’s standpoint, 3D movies at-home are not only getting more and more popular, but most of all, more comfortable than ever.
