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.

Display apparatus with touch sensing and force sensing functions

A dual-mode capacitive touch display panel includes first and second substrates, a display layer disposed between the first and second substrates, at least two first touch electrodes, at least two second touch electrodes, plural pressure sensing electrodes, and a shielding conductive layer. The first and second touch electrodes are disposed on the first substrate and overlap sub-pixels thereon. The first and second touch electrodes are respectively separated. The pressure sensing electrodes are disposed on the second substrate, and overlap the corresponding first or second touch electrodes in a vertical projection direction. The shielding conductive layer is disposed on the second substrate and includes plural openings, the pressure sensing electrodes overlap the corresponding openings, and the pressure sensing electrodes have a lower surface resistance than the shielding conductive layer does.
