Abstract
An energy-conserving mobile station and a means for reducing the energy consumption of a mobile station and to reduce burn-in on the display element, where a part of the liquid crystal display element (LCD) of a mobile station is switched off, when the whole display element is not needed and a limited amount of information is displayed on the switched-on part of the display element (A1). An arrangement according to the present invention can be implemented by e.g. driving the control circuit (DC) of the liquid crystal display that supports the partition of the display element to switch of certain rows of the display element in energy conservation mode and switching them on to be used, when information is desired to be displayed on all of the display element.
