TECHNICAL FIELD

The present disclosure relates to a technical field for manufacturing displays, and more particularly, to a display panel and a display device.

BACKGROUND

Currently, with continuous improvement and rapid development of touch and sensing technologies, touch panels have been widely used in various display devices.

In a touch display field, touch panels include touch structures such as external touch structures and embedded touch structures (in-cell type or on-cell type), and the on-cell structures are favored because of their high touch accuracy. For on-cell touch panels, they usually include a driving electrode and a sensing electrode. When the driving electrode and the sensing electrode are disposed, they are often disposed as metal grid structures in the prior art. Meanwhile, a fracture structure is disposed between the driving electrode and the sensing electrode. The driving electrode, the sensing electrode, and a floating block are isolated from each other by the fracture structure, ensuring touch functions while also ensuring consistency of optical effects of a display panel. However, when disposing the fracture structure, a fracture width is not easy to be controlled. If the fracture width is too narrow, it easily causes a short circuit between the electrodes and the floating block, thereby causing abnormal electrode channel capacitance. If the fracture width is too wide, it is not conducive to a design of the display panel, ultimately affecting a yield of products.

Therefore, it is necessary to propose solutions to problems of the prior art.

Technical Problem

In summary, in existing preparation technology, when designing touch electrodes, there is an unreasonable arrangement between a driving electrode and a sensing electrode.
