Abstract

This article discloses a low cost solution to a very difficult problem faced by all manufacturers of cathode ray tube (CRT) displays: how to eliminate possible detrimental effects of CRT electromagnetic interference (EMI) and other electrical emanations coming through the face of the display screen. Also, it is intended to suppress EMI screen emanations such that they are not compromising in terms of government and industry specifications. In the prior art, this has been accomplished by adding to the CRT face: glass- or plastic-laminated copper mesh screens, glass- or plastic-laminated stainless steel mesh screens, conductively coated glass or plastic screens or other similar means of protection.
