Abstract
In a mobile phone having a liquid crystal display unit, the entire liquid crystal display unit is displayed in a simple display mode at lest in a non-operating standby mode. In the simple display mode, the entire liquid crystal display unit is driven by reducing the number of gradation levels or by decreasing a liquid crystal driving voltage. By using such a controlling method, the power consumption of the liquid crystal display unit can be reduced in the non-operating standby mode. On the other hand, necessary information such as time and the amount of remaining battery is displayed such that the information can be read.
