Abstract:
1. A CRT light pen interface emulator for flat panel displays, the emulator comprising: a) a pen flat panel display that indicates at least one of a user action and a presence of a light pen emulating object positioned proximate to a display surface of the pen flat panel display; b) a light pen emulating object that is positionable proximate to the pen flat panel display; c) a processor that generates a light pen emulation signal at an output, the light pen emulation signal comprising position data for the light pen emulating object relative to the display surface of the flat panel display; and d) a light pen CRT electronic interface having an input that is electrically coupled to the output of the processor, the light pen CRT electronic interface converting the position data for the light pen emulating object into a signal that is comparable to a signal generated by a CRT light pen viewing a scanning dot on the CRT screen.
