In order to avoid damage to the stretchable display panel caused by over stretching, a sensor is required to detect the stretching state of the stretchable display panel, however, the thickness of the stretchable display panel is increased by the sensor alone, which affects the thinness and thinness of the stretchable display panel; meanwhile, if the sensor is disposed in the island region, a signal interference problem of the capacitive sensor with the thin film transistor in the island region easily occurs.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments.
The embodiment of the application provides a stretchable display panel, as shown in fig. 1-6, which is a schematic 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 bridges 20; the capacitive sensor includes a first capacitive sensor 40 and/or a second capacitive sensor 50.
The first electrode 41 of one first capacitive sensor 40 comprises a conductive layer located in one bridge region 10, and the second electrode 42 of the same first capacitive sensor 40 comprises another conductive layer located in the same bridge region 10; and/or the first electrode 51 of one second capacitive sensor 50 comprises a conductive layer located at the first bridge region 21, and the second electrode 52 of the same second capacitive sensor 50 comprises a conductive layer located at the second bridge region 22 adjacent to the first bridge region 21.
In the stretchable display panel provided by the embodiment of the application, the capacitive sensor is formed by utilizing the existing film layer 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 which is independently arranged for detecting the 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 the light and thin development of the stretchable display panel is facilitated. Meanwhile, the capacitive sensor is arranged 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 display quality of the stretchable display panel and working stability of the capacitive sensor are improved.

Therefore, the deformation state of the stretchable display panel can be detected by detecting the deformation amount of the film structure of the bridge region 20, so that the stretchable display panel is prevented from being damaged due to the fact that the elastic modulus of the flexible substrate 60 is exceeded by the overstretched state.
It should be noted that, in the embodiment of the present application, the stretchable display panel may only separately set the first capacitive sensor 40 or the second capacitive sensor 50, and may also set the first capacitive sensor 40 and the second capacitive sensor 50 in the same stretchable display panel at the same time, and those skilled in the art may set the types of the specific capacitive sensors according to the specific layout manners of the island region 10, the bridge region 20 and the open hole region 30 in the stretchable display panel.
