LCD and DLP are the leading panels used in projectors industry. The technologies of a projector determine the resolution, saturation, contrast and brightness of the final image. But, DLP and LCD have flaws too. To decide whether DLP is the best or be it LCD projector, let’s take a look at the characteristics, and specifications of these two. While LCD projectors have a sharper image and high picture quality, DLP projectors are lightweight, and handy. To decide clearly, let’s go through the specifications of DLP and LCD projectors to point out the differences!
DLP (Digital Light Processing) technology uses micro-mirrors to project images from a monitor to a large screen. DLP is seen in a controlled projection units, on the back side of projection TVs, and in a many digital cinemas projections.
LCD (Liquid Crystal Display) video projectors send light from a metallic lamp through a prism to display video, images, or computer data on a screen, or any other surface that is flat like a wall.
Projector Display Technology:
DLP was developed by Texas Instruments. DLP’s mainstream projector was built in 1996. The first lamp free 1080p projector of DLP was built in 2014. DLP technology or panel can be found in projectors from Manufacturers such as BenQ and Optoma.
LCD is the world’s advanced projection technology that gives suitably bright, and natural color, specific details. LCD’s reliability has been proved over years.
Working of DLP:
When combined with a light source and a projection lens, each mirror on a DLP chip can bend either toward the light source or away from it, making the pixel become black or white. The DLP chip can have up to two million small, invisible to naked eye, mirrors, each of them corresponds to one pixel on the final image that has been projected.
Working of LCD:
LCD was introduced in the field of multimedia by Epson in the 1980s. The panel has been licensed for use by other manufacturers worldwide. LCD’s technology can be found in projectors from Manufacturers such as Epson and Hitachi.
Pros and cons of DLP:
- Higher contrast than LCD
- Sealed optics so image
- Smaller chassis than LCD
- Generally less expensive than LCD projectors.
- Rainbow artifacts are a flaw in DLO technology. Only some people see this effect.
- Color quality is not as high as of LCD technology.
From the above data, it can be seen that LCD is better than DLP. But, on the other hand, DLP has its own advantages that play part as some useful features.
