Display device, stretchable display panel and manufacturing method thereof

A method for manufacturing a stretchable display panel, comprising any one of the following two schemes:

• performing Scheme I of the two schemes, wherein performing Scheme I comprises:
• providing a substrate and a stretchable display layer comprising a display area and a non-display area surrounding the display area;
• forming a first elastic layer on the substrate, the first elastic layer being a transparent material and having a Young's modulus greater than a Young's modulus of the display layer;
• forming a ring-shaped first plastic frame on a surface of the first elastic layer distal to the substrate, the first plastic frame being located in the non-display area;
• filling a first filling portion in the first plastic frame, the first filling portion being liquid or solid having a Young's modulus not greater than that of the display layer;
• providing the display layer on a surface of the first plastic frame distal to the substrate, wherein the first elastic layer is fixedly connected to the non-display area through the first plastic frame;
• forming a ring-shaped second plastic frame on a surface of the display layer distal to the substrate, the second plastic frame being located in the non-display area;
• forming a second elastic layer on a side of the second plastic frame distal to the substrate, the second elastic layer being fixedly connected to the non-display area through the second plastic frame, and the second elastic layer being a transparent material and having a Young's modulus greater than that of the display layer;
• and
• peeling off the substrate from the first elastic layer;
• and
• performing Scheme II of the two schemes, wherein performing Scheme II comprises:
• providing a substrate and a stretchable display layer comprising a display area and a non-display area surrounding the display area;
• forming a first elastic layer on the substrate, the first elastic layer being a transparent material and having a Young's modulus greater than a Young's modulus of the display layer;
• forming a ring-shaped first plastic frame on a surface of the first elastic layer distal to the substrate, the first plastic frame being located in the non-display area;
• providing the display layer on a surface of the first plastic frame distal to the substrate, wherein the first elastic layer is fixedly connected to the non-display area through the first plastic frame;
• forming the second elastic layer on a side of the display layer distal to the substrate, and connecting the first elastic layer to the display layer by a first connecting part, comprises:
• forming a ring-shaped second plastic frame on a surface of the display layer distal to the substrate, the second plastic frame being located in the non-display area, and the second plastic frame having a notch;
• forming a second elastic layer on a surface of the second plastic frame distal to the substrate, the second elastic layer being fixedly connected to the non-display area through the second plastic frame;
• injecting a transparent liquid filler into the notch to form a first filling portion in the first plastic frame;
• blocking the notch;
• and
• peeling off the substrate from the first elastic layer.

A display device, comprising:

• a stretchable display panel, comprising:
• a stretchable display layer comprising a display area and a non-display area surrounding the display area;
• a first elastic layer disposed on a side of the display layer and connected to the non-display area by a first connecting part, the first connecting part being disposed in the non-display area;
• and
• a second elastic layer disposed on a side of the display layer distal to the first elastic layer and connected to the non-display area by a second connecting part, the second connecting part being disposed in the non-display area, wherein:
• both the first elastic layer and the second elastic layer are transparent materials, the first elastic layer has a Young's modulus greater than that of the display layer, and the second elastic layer has a Young's modulus greater than that of the display layer;
• the first connecting part comprises:
• a first plastic frame sandwiched between the first elastic layer and the display layer, and located in the non-display area, the first plastic frame being in a ring-shape, wherein the first elastic layer is fixedly connected to the display layer through the first plastic frame;
• and a first filling portion filled in a space enclosed by the first plastic frame, and the first filling portion being liquid or solid having a Young's modulus is not greater than that of the display layer;
• and
• the second connecting part comprises:
• a second plastic frame sandwiched between the second elastic layer and the display layer, and located in the non-display area, the second plastic frame being in a ring-shape, wherein the second elastic layer is fixedly connected to the non-display area through the second plastic frame.
