Title
(EN) FLEXIBLE ELECTRODE-BEARING ARTICLE
(FR) SUPPORT D'ELECTRODE SOUPLE
Abstract
(EN)
An improved electrode for use in displays, including those of the touchscreen type, has a conductive polymeric material disposed over the electrode material at those regions where the electrode is subject to flexing in use, thereby putting the electrode material at risk of cracking. The conductive polymeric material bridges any cracks which may develop, thus providing electrical continuity.
(FR)
Electrode améliorée destinée aux écrans de visualisation, notamment du type écran tactile, constituée d'un matériau polymère conducteur disposé sur le matériau d'électrode dans les régions où l'électrode est susceptible de fléchir lors de l'utilisation, ce qui crée un risque de fissuration du matériau d'électrode. Le matériau polymère conducteur soude les fissures éventuelles, assurant ainsi la continuité électrique.
