Get "New Electric Screen Control" App Review for Free! Liquid Crystal Display (LCD) screens are used in television and computer monitor displays. LCD technology is capable of high definition output for sharp, crisp picture quality. LCD technology has been around for decades, but it wasn't until 2007 that LCD screens became affordable and popular enough to surpass Cathode Ray Tube (CRT) models in sales. If you're used to older CRT televisions and computer monitors, you'll find that controlling a newer LCD screen isn't too different.
