You’re sitting at a work conference and you’re bored by the presentor. You start wondering about the facility and things like the projector being used for the seemingly endless powerpoint slideshow . Suddenly you’re surfing the net trying to figure out how LCD projectors actually work.
Like most LCD electronics, the projector utilizes a liquid crystal display . It passes light through a prism that separates the light into red, green, and blue and then projects that light through the LCD panel. The lamps used are generally metal halide lamps which offer the perfect color temperature and spectrum for providing the widest range of colors. The panels are usually a combination of LCD panel with an analyzer and polarizer.
While many conference facilities own their own projectors, most mid-sized and small businesses don’t. When they need to present to clients or other groups, they usually consider an lcd projector rental to be an ideal investment.
Now that you’ve figured out how it all works, it’s probably time to get back to watching that presentation, or at least try to look like you are.
