TV Projector Plans
To get started you need to know how these projectors work. It's quite simple really; the
projector uses a different light source other than the LCD monitor. It magnifies the
picture with one or more lenses and with the power of an alternate light source. It then
projects it onto a screen for viewing.

Why use an LCD projector over a standard CRT/TV frensnel lens magnified projector?
These types of projectors are large and heavy, and if you ever tried to make one, you will
have found out that the picture quality is usually poor regardless of the type and size of
lenses used.
Even if the room is pitch black! The light source from a standard TV is just
not strong enough to give you a clear, bright picture. If you try and use a different light
source, you'll find that the glass screen of the TV causes enough of a glare to overshadow the
picture and you wind up not seeing anything.
You can get anti glare polarizing shields
for a standard TV, but the cost is very high in comparison to an LCD. LCD's, or Liquid
Crystal Display TV's are perfect for these types of projectors because the anti-glare
screen comes with the TV, and it can be adjusted for different light conditions.
The LCD's will come with standard RCA video inputs, sometimes expanded from a 1/8th inch jack.
Pixel count, and therefore resolution and picture quality is quite important.
The better quality the LCD, the better the final projected image will be.
If you're choosing this method of building a projector, you don't have to worry
about taking your LCD monitor apart, because this projector uses a direct reflection method,
rather than a pass through transmissive method that would require you to take the backlight
off your LCD monitor.
