A touch display panel includes a first substrate, a second substrate, a capacitive sensor layer and a barrier layer. The array of the light-emitting element is disposed on the side of the first substrate. The second substrate is parallel to the first substrate and is above the first substrate. A gap is arranged between the first substrate and the second substrate. The capacitive sensor layer is disposed on the side of the second substrate facing to the first substrate. The capacitive sensor layer includes a plurality of capacitors. The barrier layer is disposed between the second substrate and the capacitive sensor layer and the barrier layer is provided with an electromagnetic shielding pattern. The electromagnetic shielding pattern shields a part of the plurality of capacitors. Wherein, the plurality of capacitors shielded by the electromagnetic shielding pattern are defined as the pressure sensor units, and the plurality of capacitors not shielded by the electromagnetic shielding pattern are defined as the
