Electromagnetically-countered display systems and methods

摘要

The present invention relates to an electromagnetically-countered display system including at least one wave source and at least one counter unit, where such a wave source irradiates harmful electromagnetic waves and the counter unit emits counter electromagnetic waves for countering the harmful waves therewith. More particularly, the present invention relates to various counter units for the electromagnetically-countered display system and to various mechanisms to counter the harmful waves with the counter units, e.g., by matching configurations of the counter units with those of the wave sources, by matching wavefronts of the harmful waves with those the counter waves, and so on. The present invention also relates to various methods of countering the harmful waves with such counter waves by source and/or wave matchings, various methods of providing the counter units for emitting the counter waves defining desired wave characteristics, and the like. The present invention further relates to various processes for providing the electromagnetically-countered display systems and their counter units. The present invention further relates to various electric and magnetic shields employed either alone or in conjunction with the counter units for minimizing irradiation of the harmful waves from the shaving system.

主权项

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.
