LCD tech, meanwhile, uses a prism to split a light source into red, green and blue beams.
The biggest drawback is the rainbow effect, or bright red/blue/green artifacts that affect some viewers more than others. The benefits of the tech are portability, high contrast, less fringing and cheaper projectors, especially 4K and ultra-short-throw models. Both use mirrors that tilt by +12 and -12 degrees for white and black, but TI recently unveiled a new 0.47-inch 4K-capable DMD with +/-17 degrees of tilt, which should enhance both brightness and contrast.ĭLP projector makers include LG, Optoma, LG, BenQ and Panasonic. Those tilt either toward the light source (on) or away from it (off) at up to 5,000 times per second.īudget projectors like BenQ’s HT3550i use TI’s 0.47-inch DMD, while higher end models, like the Samsung Premium LSP9T use the 0.66-inch chip. The heart of the tech is an optical semiconductor called a digital micromirror device (DMD) that contains millions of aluminum mirrors.
Most projector manufacturers now use DLPs, or digital light processing units, manufactured nearly exclusively by Texas Instruments (TI). That’s essentially a lifetime of use (about 10 years). Lasers are a far better solution than lamps, because they’re brighter and last far longer - up to 30,000 hours instead of 6,000. The rise of ultra-short-throw projectors and brighter long-throw models, meanwhile, has been powered by falling prices in laser illumination technology. They’re fundamentally different systems, with their own advantages and drawbacks. Here are the basics: Projectors generally use two types of technology, LCD and DLP.
