  • a display screen including an array of digitally addressable pixels, each pixel being capable of showing a sustained image on the display screen;

    a display screen processing unit including at least one processor and at least one memory, the at least one memory being operatively coupled to the at least one processor, the processor and memory being adapted to process and store successive images to be shown on at least a first portion of the display;

    a clock operatively coupled to the display screen processing unit, the clock operating at a frequency and providing a signal that is usable by the display screen processing unit to update the pixels in the display screen;

    wherein the display screen processing unit is adaptedto receive and cause to be shown on at least the first portion of the display screen first images and second images that are received in a manner to indicate a required update rate for each image received, first images being updated at a first rate that is lower than a second rate at which second images are to be updated,to determine whether the images to be shown on the display are first images or second images,to cause the pixels in the first portion of the display to be updated at the first rate when first images are to be shown on the first portion of the display to thereby reduce power consumption by the first portion of the display device when it is used to display the first images, andto cause the pixels in the first portion of the display to be updated at the second rate when second images are to be shown on the display to thereby enhance quality of the second images displayed.
