Active-matrix liquid-crystal displays are eventually expected to replace the cathode-ray technology used in televisions and most computers.

Three years ago researchers at the Xerox research center here demonstrated a 13-inch prototype active-matrix liquid-crystal display with a total of 6.3 million picture elements, or pixels.

In 1972, the first active-matrix liquid-crystal display panel was produced in the United States by T Peter Brody's team at Westinghouse, in Pittsburgh, Pennsylvania.

The decision was made in response to a complaint by American manufacturers of active-matrix liquid-crystal displays, including OIS Optical Imaging Systems, the company that is now asking for the taxes to be dropped.

An active-matrix liquid-crystal display (AMLCD) is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color gamut and response time.
