Patent attributes
A touch display device including a first substrate, a second substrate, a display medium layer, a pixel electrode layer, a touch electrode structure, and a force-sensing layer is provided. The second substrate is opposite to the first substrate. The display medium layer is disposed between the first substrate and the second substrate. The pixel electrode layer is disposed between the display medium layer and the first substrate. The touch electrode structure is disposed on the second substrate and includes a driving electrode layer and a touch-sensing layer. The force-sensing layer is disposed on the first substrate, and a variable gap exists between the force-sensing layer and the driving electrode layer. A driving method of the touch display device is also provided.
