Answer:

Projectors are the devices that is used to PROJECT rays of light, especially an apparatus with a system of lenses for projecting slides or FILM on to a screen.There are two common types of projectors: DLP (digital light processing), and LCD (liquid crystal display). In the early days of projectors, CRT (cathode ray tube) projectors were commonly used. They utilized three tubes, one for each of the primary colors. Due to their large size, low light output and the frequent need to converge and align the IMAGES projected from each of the three tubes, they are no longer commonly used.

LCD

LCD projectors work by utilizing polarized mirrors that pass and reflect only certain colors of light. This causes each channel of red, green and blue to be separated and later re-converged via a prism after passing through an LCD panel that controls the intensity and saturation of each color.

DLP

DLP projectors can be classified as one-chip or three-chip. Each chip houses millions of mirrors that reflect light thousands of times each second. One-chip DLP projectors can produce more than 16 million colors while three-chip models can produce more than 35 trillion colors. This allows DLP projectors to reproduce more natural and lifelike images. The closeness of each mirror WITHIN a chip makes it difficult to see any spaces separating the pixels and in turn creates a more fluid and crisp image compared to LCD TECHNOLOGY.
