In an LCD TV projector, a very bright light shines through a small LCD screen into a lens, which throws a hugely magnified image of the screen onto the wall.
The technology is sometimes called LCLV (liquid crystal light valve).
Can you watch TV on projector?
Users can connect the projector directly to the TV by using an HDMI cable. A few models of TVs, especially the older ones, come with VGA or RCA ports instead of HDMI ports found in the modern projectors.
What is better TV or projector?
TV projectors are much more cost-effective, at least in terms of screen size for your dollar. You can get a decent HD projector and 100-inch screen for under $1,000, whereas an 80-inch TV is going to cost you at least $1,500, if not much more.
How does a projector work?
LCD projectors work by using three liquid crystal panels, a lamp, a prism, and filters to create the image on the screen. From there the LCD panels send the light through the dichroic prism which recombines the light and sends it out the main lens in the LCD projector to the surface against which it is projected.
Why use a projector instead of a TV?
A projector can take up no floor or wall space.
Not only does the latter solution use valuable floor space, it often makes the TV the focus point of an entire living room. Instead of leaving a large wall blank for the projector to shine on, you can pull down the soft screen over any wall art you may have.
Can a projector replace a TV?
If you don’t usually watch TV shows during the day and usually only put it on for movies or streaming, and can close the curtains and block the light, a projector can produce a much larger image for less money. An $800 projector can give you a 120-inch image, while a TV that’s 80 inches costs nearly $4,000.
How much does a projector TV cost?
$1000 or less: Even under $1000, there are some truly amazing home theater projectors available. The least expensive ones are the 1280×720 models (also known as 720p). They display DVD and Blu-Ray extremely well, and some cost as little as $700.
