Abstract

Thin Film Transistor (TFT) screens are becoming more common in the workplace, replacing traditional Cathode Ray Tube (CRT) screens. As the TFT screen does not generate a scan line, traditional methods of light sensing pens do not work effectively on a TFT screen. This paper describes a novel light pen type peripheral, which may be used on either a TFT or CRT screen.
