What is LCD Technology?

Liquid Crystal Display (LCD) projectors pass light through LCD panels about the size of a postage stamp; the LCD panel is made up of miniscule panels ('pixels') that can be clear, opaque or some semi-clear point in between. These pixels take the form of the image to be created, and the light passes through the clear or partly-clear areas in the same way that light passes through the clear or gray parts of a negative.

The projector's lens, in turn, expands the image and directs the light onto the screen or viewing surface. This enlarges all the tiny details and creates clear, detailed and beautiful images with ultra-smooth movement.

How does LCD work?

A light source (lamp) projects white light onto a combination of dichroic mirrors that split the light into its three basic video colours: red, blue and green.
Each of the three colors of light is then passed through its own LCD panel. Each LCD chip takes the electrical signal it receives and creates an image.
The three colour images are then combined using a prism to form a full-color image consisting of millions of colors which passes through a lens and is projected onto a screen.
