3LCD is the technology that powers the majority of all education, business, and home theater projectors.
Two dichroic mirrors are used in 3LCD systems to divide the light from the lamp into red, green, and blue. The base glass of these two mirrors is coated with a thin film that reflects only light of a specific wavelength.
3LCD is a marketing organization created and run by Seiko Epson Corporation to promote 3LCD technology and educate consumers about its benefits. Many prominent projector manufacturers use 3LCD technology and license the 3LCD logo.
