Abstract (en)

[origin: FR2781305A1] The display mechanism has two transparent or reflecting walls (2,4) holding a liquid (6) which absorbs the light. The outer walls are flexible and there is a mechanism to vary the wall thickness at intervals. Varying the thickness varies the absorption and hence the luminosity at a particular point.
