Abstract
A display apparatus with touch sensing and force sensing functions includes a display panel, a first touch device, a conductive layer and a dielectric layer. The first touch device includes multiple touch sensing pads. The conductive layer includes multiple force sensing pads electrically connected to each other, where the touch sensing pads separately overlap the corresponding force sensing pads in a vertical projection direction. The dielectric layer is disposed between the conductive layer and the first touch device. The touch sensing pads, the dielectric layer and the force sensing pads form a force sensing device.
