Abstract

A pressure sensing touch device includes a control unit, and a pressure-sensing touch panel including a substrate, a first sensing layer, a first insulating layer, a driver layer, a second insulating layer and a second sensing layer; the first sensing layer, the driver layer and the second sensing layer electrically connected to the control unit for detecting the touch location of an external object and the pressure according to changes of capacitive coupling respectively between the first sensing layer and the driver layer and between the driver layer and the second sensing electrode. The deformation amount of the second insulating layer is greater than that of the first insulating layer when receiving a pressure, making closer distance between the driver layer and the second sensing layer and significant change of the capacitive coupling, for accurately detecting the pressure applied by the external object to the pressure-sensing touch panel.
