3D Projectors – An Ever Evolving Technology
Forms of 3D projection have been around longer than one might think. To be more specific, they exist for over 60 years, but since the technology was greatly limited, it did not manage to survive. It didn’t exactly die either, it went into hibernation. A couple of brief attempts of comebacks happened, but the result was the same. Until recently that is. Since technology greatly advanced, 3D projectors are no longer oversized, complex and hard to use devices that offer poor quality and weird looking effects. Timing and synchronization issues are gone for good, and the price is more than affordable to most users.
How Do 3D Projectors Work?
Simply put, 3D projector generates two overlapping images in order to fool the viewer’s brain by changing the way it perceives depth. One image is reserved for the right eye, while the other one is reserved for the left eye. This is achieved by using a special type of two lenses which are separated from each other horizontally, and the end result is the impression of depth, the image that is extended farther away from the screen’s surface, or moved in front of the screen. In truth, the entire technology is much more complex than this, but this is the general idea behind it. Different iterations of 3D projectors do exist, but they all have the same purpose. Should you go for this projector, you will require 3D glasses in order to achieve best results. Viewing the screen without the glasses will result in a distorted image with unnatural colors.
What is 3D Ready
3D ready means that the projector will accept at least one 3D format (a signal from the source, computer, console, blu-ray player and others). These types of projectors will generally suit any purpose from gaming to watching 3D movies. In business, they can be used to display 3D charts, sheets, drawing sections, etc. However, you need to be absolutely certain which format the projector you are interested in supports, as the one you need might not be supported. For the ultimate experience, a Full HD 3D projector might be worth looking into, though they can get a bit expensive. In the end, it all depends on what the projector is expected to do. Displaying still images for business purposes require a cheaper, less powerful projector, while video games and movies will require a high-end 3D projector, provided that high quality experience is expected.
