Abstract: A touch panel-based switch includes a control circuit layer, a sensing layer, a dielectric layer, and a touch operation layer, stacked in the order. The sensing layer electrically connected to the control circuit layer includes plural sensing cell, and the dielectric layer is flexible. The touch operation layer is flexible as well and includes a button area and an adjacent non-button area. The button area includes a ground plane stacked on the dielectric layer and a first touch cover stacked on the ground plane, and the non-button area includes a second touch cover stacked on the dielectric layer. Plural though openings are provided in the button area corresponding to the sensing cells such that a portion of the dielectric layer is exposed.

Abstract: A touch sensitive device includes a capacitive touch panel with plural electrodes, a driving and sensing circuit electrically connected to the electrodes through sensing lines, and at least one conductive member. The conductive member is arranged orthogonal to and crosses the sensing lines without contact and is electrically connected to the driving and sensing circuit. Therefore, a stable coupling capacitance is provided for a one dimensional capacitive touch panel for improved touch sense performance.
