[0016] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in detail in conjunction with the accompanying drawings below. Note that the embodiments can be implemented in multiple different forms. A person of ordinary skill in the art can easily understand the fact that the methods and contents can be transformed into various forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the contents described in the following embodiments. In the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other.

[0017] In the drawings, the size of each component, the thickness of a layer, or the area is sometimes exaggerated for the sake of clarity. Therefore, one embodiment of the present disclosure is not necessarily limited to this size, and the shape and size of each component in the drawings do not reflect the true proportion. In addition, the drawings schematically show ideal examples, and one embodiment of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0018] In the present specification, ordinal numbers such as “first”, “second” and “third” are provided to avoid confusion among constituent elements, and are not intended to limit the number.

[0019] In this specification, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0020] In this specification, "electrical connection" includes the case where components are connected together through an element having some electrical function. There is no particular limitation on the "element having some electrical function" as long as it can transmit and receive electrical signals between the connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having various functions.

[0021] The term "about" in the present disclosure refers to a numerical value that is not strictly limited to allow for process and measurement errors.

[0022] A touch display panel generally includes a polarizer (POL). POL contains a large number of conductive particles. The activity of the conductive particles changes with the change of ambient temperature. When the temperature is high, the activity of the conductive particles increases. The enhanced conductivity of the POL increases the coupling capacitance of the touch area, and the amplitude of the touch signal increases, resulting in the undesirable situation of signal residual. When the temperature is low, the activity of the conductive particles decreases, the conductivity of the POL decreases, the coupling capacitance of the touch area decreases, and the amplitude of the touch signal decreases, resulting in the undesirable situation that the touch signal cannot be detected.
