Digital Light Processing (DLP) is a trademark owned by Texas Instruments, representing a technology used in projectors and video projectors. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments.
One application is DLP front projectors (small standalone projection units). DLP, along with LCD and LCoS, are the current display technologies behind rear-projection television, having supplanted CRT projectors. These rear-projection technologies compete against LCD and Plasma flat panel displays in the HDTV market.
DLP is also one of the leading technologies used in digital cinema projection.
Digital micro-mirror device
In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micr
omirror Device (DMD). Each mirror represents one or more pixels in the projected image. The number of mirrors corresponds to the resolution of the projected image (often half as many mirrors as the advertised resolution due to wobulation). 800x600, 1024x768, 1280x720, and 1920x1080 (HDTV) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or on to a heatsink (called a light dump in Barco terminology). Rapidly toggling the mirror between these two orientations (essentially on and off) produces grayscales, controlled by the ratio of on time to off time.

As far as i know DLP is DUAL-LINEAR PROGRAMMING... but as you have mentioned it is Digital Light Processing (DLP). I am very much confused could you please check it out with the website ieee.org and get me cleared too......
what is the difference between the ACCELEROMETER and the cyclotrons or synchrotron ? Could you be distinct in these ? If yes do it please it will be very helpful for a beginner. THANKS
mems is commercial concept and in fact many devices like mems accelerometer, pressure sensor, micromirror are commercially available. so mems is a concept that has been implemented and used.
whereas nano is growing. its now available commercially. but not as mems, just because of the fact that its growing and new concept whereas mems is around 15-20 years old.
Hey anjani really a nice blog..... add some more stuff on your blog but it's still nice. Well done....
