Roentgen

Roentgen is IBM's development name for a liquid crystal display ( LCD ) that has 2560 x 2048 pixels and is described as providing an image "as precise as the original paper document." Roentgen can provide an image resolution of up to 200 pixels per inch.

The Roentgen display is a form of active matrix LCD (AMLCD). Aluminum and copper are used, instead of the traditional molybdenum and tungsten. Aluminum and copper are better conductors, and make possible a higher resolution at moderate cost. Display sizes vary from approximately 16 inches to 22 inches diagonal measure. The images are more than four times as sharp as those in a high-end high-definition television ( HDTV ) display.

AMLCD displays such as Roentgen are used mainly in high-end graphics applications. However, this type of display also has advantages in text applications. Because it renders text more cleanly than displays having lower resolution, Roentgen allows some people to read online text faster and with less fatigue than is possible with older technologies. In addition, the expanded effective screen area makes it possible to render a large amount of information on a single screen.

A typical Roentgen display contains more than 8600 feet of thin-film wiring. The backlight consumes 44 watts of power, about the same as a conventional cathode-ray tube ( CRT ). The entire unit weighs about 20 pounds and is housed in a box measuring less than 10 inches deep.

The development name apparently is derived from Wilhelm Rvntgen, the physicist who discovered X-rays.
