THE PROJECTOR

TECHNOLOGY

JAYMIE Q. OCAMPO

STEM 11-10

The projection technology was directly affected at every improvement in computer technology. By 1984, you could have an LCD projector in your home, making the first “real” home theaters possible. In 1990, the first computer projector was introduced. It combined the projector and the digital projection panel, creating a fully-integrated projecting system that worked with virtually any computer. In 1992 we get the video projector, which receives a video signal, and then uses a system of lenses to project the intended image on the screen.

This is where things go from focusing on optimizing the mode of image projection, to an obsessive drive to optimize the quality of the image instead. You’ll notice this period of the ‘90’s to today is all about audiovisual tech. 4K HDTV is a thing now, as is watching 3D movies in the comfort of your home theater. Video games look creepy-real – almost uncanny, and CGI in movies is nearly flawless. Digital ads are everywhere, and some cell phones have screens nicer than most laptops. Projection technology is right in the thick of it; the first 3D projector is 12 years old now. This projector presented 2 versions of the film at the same time, making a movie look 3D when you wear those red-and-blue-lensed glasses. And in the last couple years, what do you know? – They’ve made a 4K projector for home theaters.
