In various embodiments of the present invention, by designing the receiving electrode not to overlap the transistor, the received touch signal can be prevented from being interfered by the electric signal of the transistor, thereby improving the touch sensitivity. In some embodiments, a single-sided double-layer touch electrode configuration is adopted. At this time, the connection electrode connected to the receiving electrode is designed not to overlap the transistor, which can further prevent the received touch signal from being interfered by the signal from the transistor. , Thereby improving touch sensitivity.

Although the present invention has been disclosed as above in various embodiments, It is not intended to limit the present invention. Any person skilled in the art can make various modifications and retouching without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be defined by the scope of the attached patent Prevail.
