A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.
There are many benefits of using projectors for home entertainment. In simple terms, they range from the adaptability of
projectors as gadgets to better eye health. Projectors can be a much better option than a TV for home entertainment purposes.
There are a lot of reasons why projectors are best to have in your home and you can use them in many ways that you might not
even be aware of. In this blog, we tell you why you should have a projector and how you can make the most of it.
The most common type of projector used today is called a video projector. Video projectors are digital replacements for
arlier types of projectors such as slide projectors and overhead projectors. These earlier types of projectors were
mostly replaced with digital video projectors throughout the 1990s and early 2000s,[1] but old analog projectors are
still used at some places. The newest types of projectors are handheld projectors that use lasers or LEDs to project images.
