Abstract (en)
Apparatus for use with a video display terminal (12) for the discharge of static electricity accumulated on a user to the ground circuit of the terminal. The apparatus includes a touchplate (40, 76) of conductive material adapted to be electrically connected to a conductive filter screen (17, 70) mounted over the display surface (18) of the video display terminal. The touchplate (40, 76) may be attached to the frame (16, 74) of the filter screen or may be a means remote from the screen but electrically connected to the screen. An indicator light (82) may also be interposed in the discharge path to indicate that the static charge has been discharged. The user of the terminal merely touches the touchplate to discharge static electricity to the filter screen.
