CRT light pen interface for flat panel displays

摘要

A CRT light pen emulating interface with power save and remote access for flat panel displays includes a pen flat panel display that indicates at least one of a user action with a light pen switch or other device and a presence of a light pen emulating object positioned on or proximate to a display surface of the electromagnetic pen flat panel display. A light pen emulating object is positioned proximate to the electromagnetic pen flat panel display. A processor generates a light pen emulation signal comprising position data for the light pen emulating object relative to the display surface of the electromagnetic flat panel display. A light pen CRT electronic interface converts the position data for the light pen emulating object into a corresponding signal that is comparable to a signal generated by a CRT light pen viewing a scanning dot on the CRT screen.

主权项

1. A CRT light pen interface emulator for flat panel displays, the emulator comprising:
a) a pen flat panel z-axis sensing display that indicates at least one of a user action and a presence of a light pen emulating object positioned proximate to or on a display surface of the pen flat panel z-axis sensing display; b) a light pen emulating object that is positionable proximate to and on the pen flat panel z-axis sensing display; c) a processor that generates a light pen emulation signal at an output, the light pen emulation signal comprising three-dimensional 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 three-dimensional 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.
