The invention discloses a touch panel, a touch liquid crystal screen and a driving method of the touch panel, and belongs to the technical field of touch. The touch panel comprises a substrate and a touch electrode arranged on the substrate, wherein the touch electrode comprises a first electrode and a second electrode; the touch panel also comprises a switching unit; the touch electrode and a touch sensing circuit are disconnected in a heating stage; the first electrode, the second electrode and a power supply are controlled to form a conducted loop; the first electrode and the second electrode are used for heating to realize a heating function; in a touch stage, the touch electrode and the power supply are disconnected so as to disconnect the first electrode from the second electrode; and in addition, the touch electrode and the touch sensing circuit are connected again so as to stop heating to realize a touch function. Therefore, the own touch electrode structure of the touch panel can be adopted to realize self heating at a low temperature, and influence on the normal work of the touch panel at the low temperature can be avoided.
