Abstract

La présente invention concerne une structure de commande tactile. La structure de commande tactile comprend une pluralité de premières électrodes de maille agencées en une pluralité de rangées et une pluralité de secondes électrodes de maille agencées en une pluralité de colonnes. La structure de commande tactile comprend une pluralité de blocs de maille pliables le long d'une direction de colonne, et une pluralité d'espaces respectivement dans la pluralité de blocs de maille pliables. Dans un bloc de maille pliable respectif de la pluralité de blocs de maille pliables, un espace respectif de la pluralité d'espaces comprend une pluralité de lignes s'ouvrant respectivement de façon à rompre de multiples lignes de maille du bloc de maille pliable respectif. Les espaces d'espace respectifs séparent le bloc maillé pliable respectif en un premier demi-bloc de maille respectif et en un second demi-bloc de maille respectif directement adjacents l'un à l'autre, qui sont isolés l'un de l'autre par l'espace respectif.
