Epson has been the world leader in designing and building poly-si LCD panels for projectors, for quite some time. They provide these LCD panels to most of the world's LCD projector manufacturers. It's no surprise, therefore that Epson's entire projector lineup uses LCD technology, while many other manufacturers offer product lines with both LCD and DLP technology and in some cases LCOS technology.
The Epson Home 20 home theater projector is no exception. The Home 20 is Epson's very affordable entry level home theater projector.
