Zusammenfassung:A display device has a display controller and a persistent display panel for displaying static images. The display controller has a pre-processor that extracts data for updating a frame of the display from a memory module storing display data and compresses the data. A frame buffer stores the compressed data. A display driver receives and de-compresses the compressed data from the frame buffer and repeatedly refreshes the display panel while updating the displayed frame.
