Looking for a projector so that you can watch the Super Bowl larger than life? Are you confused by the projection technologies that are in competition? Should you buy a projector that uses DLP, LCD, or LCoS? Well, let’s try to figure this out.
The oldest projection technology is LCD. LCD projection was introduced in 1984. I was in the business back then. Prior to LCD, the method of movie projection was simple. Each frame of the film—usually 35mm at the movies and 16mm at home— was a tiny, translucent photograph. The film was run through a projector at the rate of 24 frames per second, while projecting light through the film and an imaging lens. The images would then be projected onto a large screen.
In the early 90s, we had black and white LCD panels that were placed on an overhead projector. In the mid-90s, color panels came into existence followed by a LCD panel built into an overhead projector, making a one-piece projector. Shortly after that, a true projector was introduced. Since then, we have seen many improvements from the projection technology to the many features available today, including 4K resolution.
After 35 years, LCD technology is still very popular, but LCD projectors work a little differently than the panel/overhead projector system. A beam of high-intensity light travels through thousands of shifting pixels in an LCD display instead of through a frame of translucent film. Initially, there was just one LCD panel, but Epson improved on that by introducing three panels, and this technology is called 3LCD. The light splits into three hues, then travels through three LCDs before recombining in a prism to generate the crisp, colorful image projected on the screen.
