Abstract: The present disclosure provides an organic light-emitting display panel, a method for preparing the same and a display device. The method includes: providing a substrate, where the substrate includes a non-display area and a display area surrounding the non-display area; forming a barrier layer and a pixel circuit on the substrate, where an orthographic projection of the pixel circuit on the substrate and an orthographic projection of the non-display area on the substrate do not overlap; patterning the barrier layer in the non-display area to form at least one via hole penetrating the barrier layer; patterning the substrate by using the barrier layer as a mask in the non-display area to form a groove; forming a light emitting layer on the pixel circuit; and forming a thin film encapsulation layer covering the light emitting layer and the side wall of the draw-in structure on the light emitting layer.

Abstract: The present disclosure relates to a touch display device including a display panel and a support structure. The display panel includes a display portion, a bent portion and a fixed portion. The bent portion is located between the display portion and the fixed portion, and the fixed portion is bent, through the bent portion, to a back side of the display portion. The support structure includes a first protective layer and a second protective layer oppositely arranged and located between the display portion and the fixed portion, a support layer located between the first protective layer and the second protective layer, and an adhesive layer located between the support layer and the second protective layer. The adhesive layer is provided with a structure configured to disperse stress generated by the display panel during bending.
