A touch panel comprises a substrate (11) capable of propagating sound waves and a transducer (13a) mounted on the substrate to send or receive sound waves. The substrate (11) includes rounded edges (16) at its corners so that sound waves may propagate from the front to back or back to front of the substrate (11). The transducer (13a), mounted on the back of the substrate (11), receives the sound waves propagating via the rounded edges. The radius of curvature (R) of the rounded edges (16) of the substrate (11) is greater than 0.5 mm. Such a touch panel has a simplified structure, prevents projections from appearing on the surface of the propagation medium, and increases adaptability to thinner LCD monitors.
La présente invention concerne un écran tactile comprenant un substrat (11) capable de propager des ondes sonores, et un transducteur (13a) monté sur le substrat pour envoyer ou recevoir des ondes sonores. Le substrat (11) comprend des bords arrondis (16) sur ses angles de sorte que les ondes sonores puissent se propager de l'avant du substrat (11) à l'arrière et inversement. Le transducteur (13a), monté sur l'arrière du substrat (11), reçoit les ondes sonores se propageant via les bords arrondis. Le rayon de courbure (R) des bords arrondis (16) du substrat (11) est supérieur à 0,5mm. Un tel écran tactile présente une structure simplifiée, empêche la formation de projections sur la surface du support de propagation, et augmente l'adaptabilité avec des moniteurs LCD plus minces.
