Title: Display device with freely programmable multiplex rate

Abstract: The invention describes a display device for displaying information, comprising a display unit 1 with a plurality of columns C and rows R and a display driver 2. Further the invention describes a display driver 2 controlling a display unit 1 with storing means 3 for providing image information to the columns C of a display. The invention relates also to a terminal for mobile communication with a display device, having a display unit 1 and a display driver 2. To achieve a flexible multiplex rate of the display a control device 4 is arranged to switch off a definable number of rows R of the display depending on a state signal which contains the state information of the rows R. By this the multiplex rate is freely programmable, so in a partial mode (N/P=0) the multiplex rate is reduced and by this the power consumption is reduced. Further it is possible to enable the rows or the groups of rows in a none consecutive order.
