Abstract:

A non-glare, electromagnetic interference rejecting screen for a video display terminal. The screen comprises a front panel, formed of a transparent material, a rear panel, formed of a transparent material and a woven mesh screen interposed therebetween. A gasket is disposed about the front panel, with peripheral edge portions of the screen extending over the gasket. The screen is mounted on the display terminal so that the wire mesh is interposed between the gasket and the screen retaining frame, e. g. , bezel, to form a good electrical interface therebetween. The strands of the screen are disposed at right angles to one another, with none of said strands being disposed horizontally or vertically. The strands are formed of electrically conductive material and are coated with silver. The silver surface is in the form of silver sulfide to give a darkened appearance.
