DLP stands for Digital Light Processing. It is a type of digital display technology developed by Texas Instruments, Inc. DLP consists of procedures where video images are projected using a specialized light source. Usually this light source is a powerful lamp. The light produced by the source is reflected off thousands of microscopic mirrors formed on a chip. Each of the microscopic mirrors corresponds to a single pixel.
The microscopic mirrors used in DLP are set to perform specific functions. They reflect light toward the DLP lens to produce the color white. In contrast, the mirrors reflect light away from the DLP lens to produce black. Between the two said points, the mirrors modulate to produce various shades of gray. Intricate motors are used in tilting the mirrors more than a thousand times per second to a specific angle. This process will produce images as crisp and as accurate as possible.
In addition, three-chip versions are used in the DLP technology to produce the colors red, green, and blue. Once the signals have passed through the lens, they are then sent to a screen. Such equipment involved in the process are called Digital Micromirror Devices (DMD’s)
DLP is used in various applications and pieces of hardware. Most commercial projectors use the DLP technology. This enables them to provide compact, high-resolution digital displays. High Definition TVs or HDTVs are other good examples of hardware that use DLP. The wide-screen TVs and video displays used by certain theaters were made using the DLP technology.
