Abstract
The disclosure provides a sensing structure of a touch panel, which includes a shielding layer and a sensing layer. The shielding layer is provided with one hollow portion, and the sensing layer is arranged under the shielding layer and located around the hollow portion. The disclosure further provides a cover plate structure of a touch panel and the touch panel. In the touch panel, the cover plate structure of the touch panel and the sensing structure of a touch panel provided by the disclosure, the sensing layer is located under the shielding layer and around the hollow portion. Thus, the sensing layer is covered by the shielding layer and avoids the hollow portion of a pattern zone, so that the sensing layer cannot be seen through the hollow portion, and the appearance quality of the touch panel is improved.
