An electromagnetically-countered display system includes at least one wave source and at least one counter unit. The wave source irradiates harmful electromagnetic waves and the counter unit emits counter electromagnetic waves for countering the harmful waves therewith. Examples of the various counter units for the electromagnetically-countered display system and various mechanisms to counter the harmful waves with the counter units include by matching configurations of the counter units with those of the wave sources, and by matching wavefronts of the harmful waves with those the counter waves. Various methods of countering the harmful waves with such counter waves include by source and/or wave matching. Various methods of providing the counter units for emitting the counter waves defining desired wave characteristics. Various electric and magnetic shields can be employed either alone or in conjunction with the counter units for minimizing irradiation of the harmful waves from the display system.
