A display controller for use within an electronic device includes a dedicated memory and a low power display processor for displaying information when the electronic device is operating in a reduced power mode of operation (e.g., sleep mode). The memory stores display data for a predetermined image and the display processor supplies the display data to a display panel of the electronic device when the electronic device is operating in the reduced power mode. The display controller may also include a processor interface for receiving control information from the electronic device's device processor to enable the display processor to determine that the electronic device is operating in reduced power mode. The display processer may be configured to scale the stored display data when, due to memory size constraints, the memory stores the display data at a resolution that is different from (e.g., less than) the display panel resolution. |
