Problems solved by technology
The capacitive touch panel of the integrated touch structure is bonded to the display device. Since there is no touch substrate, the surrounding lines (which are made of metal) are easily exposed, and are broken down by static electricity brought by the human body or the external environment, resulting in touch control panel failure
Although the touch panel has a protective layer with an insulating function, the protective layer still cannot achieve a good electrostatic protection effect.

The invention relates to the technical field of touch control, and provides a touch control panel. The touch control panel comprises an insulated substrate, a touch control sensing layer, a peripheral circuit, a protection layer and a grounded metal layer. The insulated substrate is provided with a touch control area and a peripheral area surrounding the touch control area. The touch control sensing layer is arranged in the touch control area and a part of the peripheral area of the insulated substrate. The peripheral circuit is arranged in the peripheral area of the insulated substrate and electrically connected with the touch control sensing layer. The protection layer at least covers the peripheral circuit. The grounded metal layer is arranged on the protection layer and covers the range of the peripheral circuit. The touch control panel is provided with the grounded metal layer which can guide out static electricity which comes from internal components of the touch control panel or is generated by the human body, and has the good electrostatic discharge protection capacity.
Description
technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with a grounded metal layer, an electronic device thereof and a manufacturing method thereof. Background technique [0002] The touch panel is an input device for the operator to directly operate. The types of touch panels include: capacitive, resistive, electromagnetic, optical and other touch panels, among which capacitive touch panels are widely used. The capacitive touch panel is mainly composed of a protective glass and a touch substrate with a sensing layer. When a driving signal is applied to the sensing layer of the capacitive touch panel, if the touch panel is touched, the touch The position of the sensing layer corresponding to the touch position on the panel generates an electrical signal change. [0003] Since the operator often operates the touch panel with fingers, and the touch panel has a sensing layer that generates electrical signal changes, the human...
