Abstract (en)
The structure of these screens leads to phenomena which disturb viewing, such as more particularly disturbing staircases with fine lines rotating around one of their ends. In order to avoid this and according to the invention, the colour of a monochrome area is chosen in such a way that it is possible to give the pixels (P1, P2) surrounding the area at least a colour close to that of the pixels (P0) of the area, but with lower luminance. Application, in particular, to the visual display of measurements. <IMAGE>
