ABSTRACT:
A flat screen display system uses a two-dimension surface acoustic wave ("SAW") scanning. The flat screen is made of a piezoelectric substrate coated with a layer of piezoluminophor powder. Four SAWs having two by two nonparallel directions are launched along the piezoelectric surface. The first of the two SAWs is pulsed and the third one has a constant amplitude. The fourth SAW is modulated by the information to be displayed. With respect to the modulated SAW, the pulsed SAWs are launched with a delay that is determined by the distance to be covered by the modulated SAW, for reaching the point which the current modulation corresponds to.
