Abrégé
(EN) A touch screen display sensor is provided that includes a transparent touch-sensing element disposed upon the surface of a transparent substrate and a force-sensing element disposed within the transparent touch-sensing element. The force-sensing element includes two sets of bands of micromesh and can include a pressure-responsive material between the bands of micromesh. The bands of micromesh include traces of a metallic conductor. The sets of bands of micromesh are spaced apart and occupy substantially parallel planes.
(FR) L'invention concerne un capteur pour afficheur à écran tactile, comprenant un élément transparent de détection tactile disposé par-dessus la surface d'un substrat transparent et un élément de détection d'effort disposé à l'intérieur de l'élément transparent de détection tactile. L'élément de détection d'effort comprend deux ensembles de bandes en micromesh et peut comprendre un matériau réagissant à la pression entre les bandes en micromesh. Lesdites bandes en micromesh comprennent des traces d'un conducteur métallique. Les ensembles de bandes en micromesh sont espacés et occupent des plans sensiblement parallèles.
