Abstract

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.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch panel, a touch liquid crystal screen and a driving method for the touch panel. Background technique [0002] The touch panel is a direct embodiment of touch technology, providing people with a simple and convenient way of human-computer interaction, which greatly facilitates the operation of various electronic products. [0003] Existing touch panels are mainly capacitive touch panels. Capacitive touch panels usually include a plurality of touch electrodes arranged at intervals. Capacitance is formed between these touch electrodes and ground or between touch electrodes. The position of the touch point on the touch panel is determined by detecting the capacitance between the touch electrode and the ground or the capacitance change between the touch electrode and the touch electrode. Since the size of the capacitance is related to the temperature, the change of temperature ...
