The terms referred to in this application will first be introduced and explained:

In order to avoid damage to the stretchable display panel due to excessive stretching, a sensor is required to detect the stretching state of the stretchable display panel, but the sensor alone increases the thickness of the stretchable display panel, which affects the lightness and thinness of the stretchable display panel; meanwhile, if the sensor is disposed in the island, a problem of signal interference of the capacitive sensor with the thin film transistor in the island is liable to occur.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
Embodiments of the present application provide a stretchable display panel, which is schematically illustrated in fig. 1 to 6, and is a structural diagram of six stretchable display panels. The stretchable display panel includes: at least one island 10, at least one bridge 20, at least one open area 30 and at least one capacitive sensor; an open area 30 is located between an island 10 and a bridge 20 or between two bridge 20; the capacitive sensor comprises a first capacitive sensor 40 and/or a second capacitive sensor 50.

In the stretchable display panel provided by the embodiment of the application, the capacitive sensor is formed by utilizing the existing film structure of the bridge region of the stretchable display panel and is used for detecting the stretching state of the stretchable display panel, so that the sensor for detecting the stretching state by independent arrangement is avoided, the structure of the stretchable display panel is simplified, the thickness of the stretchable display panel can be effectively reduced, and the development of the stretchable display panel in a light and thin manner is facilitated. Meanwhile, the capacitive sensor is disposed in the bridge region 20 of the stretchable display panel, so that signal interference between the capacitive sensor and the thin film transistor in the island region 10 is reduced, and thus the display quality of the stretchable display panel and the working stability of the capacitive sensor are improved.
In the embodiment of the present application, the stretchable display panel is made of the flexible substrate 60, and when the stretchable display panel is under the action of a tensile force, the flexible substrate 60 located in the bridge region 20 and the opening region 30 is under the action of the tensile force to generate stretching deformation, so that the deformation of the stretchable display panel is realized. Therefore, the deformation state of the stretchable display panel can be detected by detecting the deformation amount of the film layer structure of the bridge region 20, so as to avoid the excessive stretching exceeding the elastic modulus of the flexible substrate 60, and further avoid the damage to the stretchable display panel.

Meanwhile, the capacitive sensor is disposed in the bridge region 20 of the stretchable display panel, so that signal interference between the capacitive sensor and the thin film transistor in the island region 10 is reduced, and thus the display quality of the stretchable display panel and the working stability of the capacitive sensor are improved.
2. In the embodiment of the present application, the film structure of the bridge region 20 of the stretchable display panel and the film structure of the display unit 100 in the island region 10 are simultaneously prepared, so that two conductive layers isolated from each other in the film structure of the bridge region and a medium between the two conductive layers can be used to form a capacitive sensor, i.e., a sensor that needs to be separately arranged to detect a stretching state is avoided, the structure of the stretchable display panel is simplified, the thickness of the stretchable display panel can be effectively reduced, and thus the stretchable display panel is beneficial to the development of lightness and thinness; meanwhile, the production process of the capacitive sensor is simplified, and the production efficiency of the stretchable display panel is improved.
