Title
(EN) TOUCH PANEL AND INTERACTIVE INPUT SYSTEM INCORPORATING THE SAME
(FR) ECRAN TACTILE ET SYSTÈME D'ENTRÉE INTERACTIF INCORPORANT CET ÉCRAN TACTILE
Abstract
(EN)
A touch panel comprises a substrate having a forward major surface and formed of a plurality of assembled substrate segments. Cover material overlies the forward major surface to reduce the visibility of seams between adjacent substrate segments.
(FR)
L'invention concerne un écran tactile comprenant un substrat ayant une surface principale avant et formé d'une pluralité de segments de substrat assemblés. Un matériau de revêtement recouvre la surface principale avant pour réduire la visibilité des joints entre segments de substrat adjacents.
