Abstract

Over the past five years we have been involved in the design of projection display products based on LCD panels. We have specialized in a particular application, where the panel is placed on the stage of a standard overhead projector and electrically connected to the video output of a personal computer. The LCD panel thus provides a low cost and portable method for projecting a computer screen large enough for group viewing. Our designs have been paced by the available LCD technology. As we refined our designs, we accumulated a ''wish list'' of LCD panel features. To our great satisfaction, most of our wish list desires have been met by the first generation of commercially available active matrix LCD panels. To set the stage for a discussion of active matrix technology, we first describe the technical characteristics of the predecessor technology, now known as ''passive matrix''. Then we explain the particular advantages of active matrix technology in our designs.
