Abstract:
1. An electromagnetically-countered display system including at least one wave source which in turn includes a plurality of base units irradiating harmful electromagnetic waves therein and capable of countering said harmful waves irradiated by at least one of said base units of said wave source by at least one of canceling said harmful waves inside a target space and suppressing said harmful waves from propagating to said target space, wherein said base units are configured to include only portions of said source which are responsible for at least one of irradiating said harmful waves and affecting propagation paths of said harmful waves therethrough, wherein said target space is defined between at least one of said base units and an user of said system, wherein said system includes at least one display screen and displays a visual image thereon, and wherein said harmful waves are configured to have frequencies less than about 10 kHz comprising: a plurality of pixels which forms said display screen, wherein each of said pixels is configured to generate each portion of said image when supplied with source electrical energy so that said pixels are configured to generate said visual image on said screen in cooperation; at least one first electrode with a first plurality of first conductive paths which are configured to be provided in a first direction and in a first arrangement in which each of said pixels is configured to electrically couple with at least one but not all of said first paths, wherein each of said first paths is configured to serve as one of said base units and to irradiate said harmful waves when supplied with said source energy; at least one second electrode with a second plurality of second conductive paths which are configured to be provided in a second direction and in a second arrangement in which each of said pixels is configured to be electrically coupled to only one of said second paths, wherein each of said second paths is configured to serve as one of said base units and to irradiate said harmful waves as supplied with said source energy; a controller which is configured to perform a selection of at least one of said first paths and at least one of said second paths, to supply said source energy only through (or across) at least one of said pixels electrically coupling with both of said selected first and second paths for generating only a portion of said image, and then to repeat said selection for the rest of said pixels until completing said image; and at least one counter unit which is configured to have a configuration at least partially similar to that of at least one of said base units and to emit counter electromagnetic waves when supplied with counter electrical energy in a preset direction, whereby said counter waves are configured to have wave characteristics which are at least partially similar to those of said harmful waves irradiated by at least one of said base units due to said configuration, to also define phase angles which are at least partially opposite to those of said harmful waves irradiated by said at least one of said base units due to said preset direction and, therefore, to counter said harmful waves irradiated by said at least one of said base units in said target space.
