In today's modern world of high technology and global business, LCD (Liquid Crystal Display) projectors are used to project presentations to a number of people at the same time. They are usually connected to a computer, and they display the presentation on a wall mounted screen display.
There are different kinds of projectors available in the market. They are:
- Standard: These have one panel of glass which controls the three primary colors.
- Poly-silicon: These have 3 panels which control the colors that allow the projector to have a higher saturation of colors, as compared to a standard model.
- DLP: DLP (Digital Light Processing) projectors have a single chip with about 400,000 micro mirrors, which control and modulate the light from it's lamp and project it to the lens. This is also known as the DMD (Digital Mirror Device) technology. These devices are commonly available in the market nowadays.
