Problems solved by technology
In the prior art, the first electrode completely corresponds to the second electrode, and the edges of the first electrode and the second electrode have a right-angle structure. When the first electrode and the second electrode are fully connected, the edge of the first electrode and the second electrode Right-angle structures tend to collide with each other and crack during connection due to stress concentration
In addition, when the first electrode and the second electrode are fully connected, the air bubbles between the first electrodes and the air bubbles between the second electrodes are not easy to be discharged smoothly.
Therefore, the existing touch display panels have poor adhesion and are prone to electrode corrosion.

Description
technical field [0001] The present invention relates to a touch device, in particular to an electrode design of the touch device. Background technique [0002] The first electrodes in the bonding area of the conventional touch display panel are used to electrically connect the second electrodes arranged along a specific direction on the flexible printed circuit (FPC). In the prior art, the first electrode completely corresponds to the second electrode, and the edges of the first electrode and the second electrode have a right-angle structure. When the first electrode and the second electrode are fully connected, the edge of the first electrode and the second electrode Right-angle structures are prone to collide with each other and crack during connection due to stress concentration. In addition, when the first electrode and the second electrode are fully connected, the air bubbles between the first electrodes and the air bubbles between the second electrodes are not easy ...
