Plasma Addressed Liquid Crystal (PALC), a New Flat-Panel Technology for Full-Color Video

Thomas S. Buzak

Current methods that attempt to provide high addressability, flat-panel displays suffer from fabrication difficulties due to the large number of active circuit elements required. A new active matrix technique forgoes the use of transistors and uses an ionized gas to electrically address a variety of electro-optic materials. This plasma active-substrate is functionally similar to a large array of transistors, but with a comparatively simpler structure. In combination with standard liquid crystal materials, plasma addressing has the demonstrated ability to address the large numbers of pixels required for video images. This technique has the potential for providing flat, full-color displays in large sizes.
