ABSTRACT:
A method and device for controlling a display to suppress noise generated from displaying elements of the display in a radio communication system. In one aspect, a display control device for suppressing noise in a radio communication system comprises: a display having N displaying elements, the N displaying elements being paired, each of the pairs having a first displaying element and a second displaying element; and a controller, operatively connected to the display, for outputting a first control voltage having a first phase to control each of the first displaying elements of the pairs, and for outputting a second control voltage having a second phase to control each of the second displaying elements of the pairs, the first phase and the second phase having a phase relationship which provides for a reduction of resultant noise generated by the N displaying elements.
