Abstract: The present disclosure relates to a multi-layer film. The multi-layer film may include a first region and a second region. The first region may include a first bonding layer and a first planarization layer directly contacted with each other. The second region includes a second bonding layer, a second planarization layer, and an intervention layer between the second bonding layer and the second planarization layer.

Abstract: A display device, a stretchable display panel, and a fabricating method thereof are described. The stretchable display panel includes a flexible substrate and a plurality of pixel islands and island-to-island connections disposed on the flexible substrate. The island-to-island connections include a first outer protective layer disposed on the flexible substrate; a first inner protective layer disposed on a surface of the first outer protective layer facing away from the flexible substrate; a conductive layer disposed on a part of a surface of the first inner protective layer facing away from the flexible substrate; a second inner protective layer configured to cover the conductive layer and the first inner protective layer; a second outer protective layer disposed on a surface of the second inner protective layer facing away from the flexible substrate; and a packaging layer configured to cover the second outer protective layer.

Abstract: A fabrication method of a display panel, a display panel and a display device are provided. The method includes: forming a piezoelectric sensing layer on a first substrate; forming a surface acoustic wave driver to excite a surface acoustic wave on the piezoelectric sensing layer; forming a passivation layer on the piezoelectric sensing layer where the surface acoustic wave driver has been formed; forming grooves in the passivation layer; dropping polymer material into the passivation layer; driving the polymer material into the grooves by the surface acoustic wave; performing a first curing, so that the polymer material is fixedly connected with the grooves; and cell-assembling the first substrate and a second substrate.
