DISPLAY SYSTEM HAVING A SEMITRANSPARENT DISPLAY DEVICE DISPLAYING SYMBOLS WITH A CONTRASTED OUTLINE

摘要

The general field of the invention is that of display systems comprising means for generating graphic symbols and an associated semitransparent display device. The display device according to the invention has two overlaid semitransparent flat display screens, one passive and the other active, each symbol displayed on the semitransparent display device comprising a first representation and a second representation. The first representation is displayed on the first display screen with a low transmission rate for the light and with a predetermined first size. The second representation is displayed on the second display screen in the same place as the first representation, with a luminance and a predetermined second size that is smaller than the first size so that the second representation is overlaid on the first representation and the displayed symbol appears bright with a dark border.
