Problems solved by technology

However, as the frame of the touch panel narrows, the distance between the shielding structure and the signal lines decreases. When the charge on the shielding structure accumulates to a certain extent, it may cause electrostatic damage to the nearby signal lines.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel including a shielding structure. Background technique [0002] The touch panel provides a simple and intuitive input method. By converting the user's touch into an electrical signal, the touch panel can be operated by the user by selecting, sliding, and the like. Common touch panels include resistive and capacitive touch panels, which operate by detecting changes in resistance and capacitance caused by touch, respectively. These changes are further transmitted to the processor via signal lines. Shielding structures may be provided between signal lines coupled to different sensing electrodes to isolate signals from different sensing electrodes. Typically, such a shielding structure can be provided as an entire strip of conductive material. However, as the frame of the touch panel narrows, the distance between the shielding structure and the signal lines decreases. When th...
