Static electric fields of TV sets and computer screens"Computer screens and television sets work on similar principles. Both produce static electric fields and alternating electric and magnetic fields at various frequencies.  Static electric fields of screens Source:WHO However, screens with liquid crystal displays used in some laptop computers and desktop units do not give rise to significant electric and magnetic fields. Modern computers have conductive screens which reduce the static field from the screen to a level similar to that of the normal background in the home or workplace. At the position of operators (30 to 50 cm from the screen), alternating magnetic fields are typically below 0.7 µT in flux density (at power frequencies). Alternating electric field strengths at operator positions range from below 1 V/m up to 10 V/m." Source & © WHO (www.who.int Related publication:
