Abstract
A touch structure, a touch panel and a touch display device are disclosed. The touch structure includes: a sensing film configured to sense a pressure applied on the sensing film to generate an electrical signal; and a heating film disposed on a side of the sensing film and configured to generate heat in response to a determination, based on the electrical signal, that the value of the pressure applied on the sensing film is greater than a preset pressure value.
