Abstract:
1. A method of displaying a visual image by a display system operating on electric current while reducing an intensity of electromagnetic waves which are irradiated by said system and which are not visible light waves, said method comprising the steps of: arranging a plurality of pixels in a preset pattern; forming a first current path electrically connecting one end of each of said pixels; forming a second current path electrically connecting another end of each of said pixels; arranging said second path to run at least substantially along said first path; and flowing said current in at least a portion of said first path in a first direction but in at least another portion of said second path in a second direction which is at least partially opposite to said first direction, whereby said electromagnetic waves irradiated along said portion of second path cancel said at least a portion of electromagnetic waves irradiated along said portion of said first path and whereby said intensity of said waves irradiated by said system is reduced.
