Patent ID: 6882332

Claim:
A display device which includes a driver circuit, an image data memory coupled to the display, and a display, with a plurality of rows R and columns C, coupled to the driver circuit, where a number p max indicates a maximum number of rows that can be simultaneously driven in the display device, where a number p indicates the number of rows selected to be simultaneously driven, where the rows R and the columns C can be driven by means of voltage values of the equally high voltages F and G MAX , and where the display has a multiplexibility of m R, wherein the display device derives the number p from the display size to be driven, and is configured to adaptively select the number p in response to a change in a display mode that controls the display size to be driven, wherein the driver circuit includes a plurality of voltage driver stages for generating corresponding partial voltage values for driving the display, and is configured to selectively switch off driver voltage stages in response to a change in the selected number p such that the number of partial voltage values that are available for driving the display during the display mode varies in dependence on the number p selected for the display mode, and wherein the display device is operable such that a number of image data bits accessed from the image memory, is equal to p max regardless of the value of p.
