DISPLAY DEVICE AND METHOD FOR OPTIMISING MEMORY PASS-BAND

摘要

The invention relates to a display device that comprises a flag memory (5) containing state flags of pixel areas of the image. The invention consists of a display device that comprises a display screen (6) and a graphical generation unit (4) implementing at least three functions for displaying an image, i.e. a first data erasure function, a second function for generating an image comprised of pixels in a first memory (1), and a third function for displaying the image by reading the pixels in said memory (1) and controlling the screen (6), characterised in that an image is divided into a plurality of separate pixel areas and in that each area is addressed by a flag, wherein the display device further includes a memory (5) that stores the flag states so that the graphical generation unit (4) can execute the display function on the basis of the flag states. The invention can be used for the generation of images having a predominantly uniform background, in particular for application in aeronautics.
