DLP is one of the finest semiconductor used today. DLP technology is designed on the application of optical semiconductor – A digital Micrometer device or abbreviated as DMD. The DMD chip which is an immensely explicit light switch that enables light to be modulated digitally. In this piece, read about what it’s and the complete working mechanism of DLP Projectors.
What is DLP Technology?
DLP or Digital Light Processing Technology is used in various digital cameras and TV etc. it works, encompassing numerous tiny mirrors so as to display the images from the monitor to that of a large screen.
It performs the task of projection with a rectangular array of microscopic mirrors which corresponds light in the projected image, coordinated well with that of the digital signal, a light source and the projection lens.
These mirrors can project videos and graphics with incredible functionality. The digital video or signal enters the DLP system, it activates the tiny electrode beneath each DMD mirror causing mirrors to tilt toward or away from a light source.
Most of the developers now use this technology in that of the various applications ranging from measuring and sensing to digital exposure to that of intelligent animation. It can also be said as a system that prevents data loss and data breaches. This DLP could be easily used with many different light sources ranging from lamps to LEDs and even lasers.
DLP Distinct Features
- Incorporates environment-friendly technology.
- For the sharper images caters more pixels.
- Clear and smooth images.
- The sealed chipset that primarily aids for preventing the dust spots.
- Lightweight profile.
- Easier to handle.
- Less expensive than other technologies.
- Renders more appealing visuals.
How DLP Projection Works
It basically relies on Digital Micrometer Device which is a semiconductor that is thumbnail sized. It primarily works like a light switch that contains the micromirrors of about 1.3 million. 5000 times in a second, it can move forth and back. The graphics signals, as well as the videos that are the incoming ones, gets converted into the digital code pertaining to the binary data of 1’s and 0’s which does the work of making the DMD mirror tilt as per requirement. When the lamp, along with the projection lens and colour wheels are been adjoined with that of the DMD panel, a digital image is formed with the combination of the tilting mirrors. This is how the DLP works.
Pros of DLP System
- Caters smoother video.
- DLP projects are efficient enough to render good contrast.
- Offer deeper blacks.
- Renders high light output.
- Greatly reduce light loss.
- Projects an accurate image without any shadows.
- Easy to maintain.
Cons of DLP System
- Rainbow effect; as the image displayed by DLP projector is completely red, green or blue colour and as a whole, it seems vibgyor light flickering.
- Possess scarce pixels.
- As compared to LCD, brightness is a bit low.
