Abstract: The present disclosure provides a method for fabricating a displaying backplane, a displaying backplane and a displaying device, and relates to the technical field of displaying. The method includes forming a first active layer and a second active layer on a substrate base plate; forming a first grid insulating layer covering the first active layer and the second active layer; forming a first grid on the first grid insulating layer; performing ion implantation to the first no-channel regions, the second no-channel regions and the second channel region, to reduce oxygen-vacancy concentrations of the first no-channel regions, the second no-channel regions and the second channel region; and forming a second grid on the first grid insulating layer.

Abstract: A stretchable display panel is provided. The stretchable display panel includes a plurality of encapsulated islands; and a plurality of bridges connecting the plurality of encapsulated islands. A respective one of the plurality of bridges connects two adjacent encapsulated islands of the plurality of encapsulated islands along an extension direction from a first one of the two adjacent encapsulated islands to a second one of the two adjacent encapsulated islands. The respective one of the plurality of bridges includes a plurality of first parts and a plurality of second parts alternately arranged. The stretchable display panel includes an insulating layer. The insulating layer includes a plurality of insulating blocks respectively in the plurality of first parts. The insulating layer is at least partially absent in the respective one of the plurality of second parts.
