CA 2563566

A tensioned touch panel (10, 110, 310, 410, 510) includes a support structure having a substrate (14, 214, 314, 514) with a generally planer conductive surface (22) disposed thereon and an insulating spacer (30, 130, 230, 330, 430) generally about the periphery of the substrate. A pretensioned conductive membrane (40, 340, 440, 540) overlies the support structure. The spacer separates the conductive membrane and the conductive surface thereby to define an air gap (48) therebetween. The conductive membrane is secured to the support structure under sufficient tension to inhibit slack from developing in the conductive membrane as a result of changes in environmental conditions. A method of assembling a tensioned touch panel is also provided.

L'invention porte sur un écran tactile tendu (10, 110, 310, 410, 510) comprenant une structure de support dotée d'un substrat (14, 214, 314, 514) présentant une surface conductrice généralement plus plane (22) disposée dessus et un espaceur isolant (30, 130, 230, 330, 430) généralement situé autour de la périphérie du substrat. Une membrane conductrice prétendue (40, 340, 440, 540) recouvre la structure de support. L'espaceur sépare la membrane conductrice de la surface conductrice, ce qui permet de définir un entrefer (48) entre les deux. La membrane conductrice est fixée à la structure de support avec une tension suffisante pour empêcher l'apparition d'un relâchement dans la membrane conductrice suite aux changements des conditions de l'environnement. L'invention porte sur un procédé d'assemblage d'un écran tactile tendu.
