An acoustic touch panel (100) utilizes acoustic waves within a sensor substrate to determine the position of touch. The substrate (1) is made of a glass having an attenuation coefficient of less than or equal to about 0.6 dB/cm as determined at the substrate surface for 5.53 MHz Rayleigh waves as measured by the slope of a plot of amplitude versus distance for a signal through a pair of facing 0.5 inch wide wedge transducers mounted on the glass under test having sufficient thickness to support Rayleigh wave propagation.
L'invention porte sur un panneau tactile (100) de type acoustique mettant en oeuvre des ondes acoustiques dans un substrat de capteur de façon à déterminer la position d'effleurement. Ce substrat (1) est fait dans un verre trempé dont le coefficient d'atténuation est inférieur ou égal à environ 0,6 dB/cm mesuré au niveau de la surface du substrat pour des ondes Rayleigh de 5,53 MHz selon une pente de tracé amplitude/distance pour un signal traversant une paire de transducteurs opposés à coin large de 0,5 pouces, montés sur le verre de test d'une épaisseur permettant la propagation des ondes Rayleigh.
