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.

Abstract

The invention discloses a touch device which comprises a substrate and a circuit board. The substrate comprises a touch sensing structure and multiple first electrodes, wherein the touch sensing structure is formed on the substrate, the multiple first electrodes are electrically connected to the touch sensing structure, multiple first intervals are formed the multiple adjacent first electrodes, and the minimum distance among the multiple adjacent first electrodes is one interval distance of the first intervals. The circuit board and the substrate are partially overlapped in the vertical projection direction. The circuit board comprises multiple electrodes. The multiple electrodes are formed on the circuit board. Multiple second intervals are formed among multiple second electrodes. At least one of the multiple first electrodes and at least corresponding one of the multiple second intervals have a deviation distance in the first direction, and the deviation distance is greater than zero but is smaller than one half of the corresponding interval distance.

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 ...
