Abstract
A display device that comprises a flag memory containing state flags of pixel areas of the image is provided. The display device comprises a display screen and a graphical generation unit 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, and a third function for displaying the image by reading the pixels in said memory and controlling the screen, in which 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 that stores the flag states so that the graphical generation unit can execute the display function on the basis of the flag states. The generation of images having a predominantly uniform background can, in particular, be used for application in aeronautics.
