Abstract
(EN) The present invention relates to a touch panel comprising an inductive electrode layer and a patterned protective layer covering the inductive electrode layer, wherein a forming pattern of the patterned protective layer is identical to that of the inductive electrode layer. The present invention further provides a touch panel manufacturing method. According to the touch panel and the manufacturing method provided by this invention, by means of covering the inductive electrode layer with the patterned protective layer, the patterned protective layer isolates the inductive electrode layer from contacting with oxygen during baking, influences of oxygen on square resistance change of conductive materials under high-temperature baking can be overcome, and accuracy of identification of touch positions of the touch panel is improved.
(FR) La présente invention porte sur un panneau tactile comprenant une couche d'électrode inductive et une couche protectrice à motif couvrant la couche d'électrode inductive, un motif de formation de la couche protectrice à motif étant identique à celui de la couche d'électrode inductive. La présente invention porte en outre sur un procédé de fabrication de panneau tactile. Selon le panneau tactile et le procédé de fabrication décrits par cette invention, au moyen du recouvrement de la couche d'électrode inductive par la couche protectrice à motif, la couche protectrice à motif isole la couche d'électrode inductive contre un contact avec de l'oxygène durant la cuisson, des influences de l'oxygène sur une variation de résistance carrée de matériaux conducteurs sous cuisson à haute température peuvent être surmontées, et la précision d'identification de positions de touchée du panneau tactile est améliorée.
(ZH) 本发明涉及一种触控面板,包括:一感应电极层;以及一图案化保护层,覆盖该感应电极层;其中,该图案化保护层的形成图案与该感应电极层的形成图案相同。本发明还提供一种触控面板制造方法。本发明所提供之触控面板及制造方法,藉由图案化保护层覆盖在感应电极层上,在烘烤的过程中,图案化保护层隔绝感应电极层与氧气接触,克服氧气对导电材料在高温烘烤条件下方块电阻变化的影响,而提高触控面板辨识触碰位置的精准度。
