Stretchable substrate structure and the manufacturing method thereof, stretchable display and the manufacturing method thereof, and operating method of stretchable display

A method for manufacturing a stretchable display, the method comprising:

• preparing a carrier substrate;
• forming a stretchable substrate on the carrier substrate;
• forming a stretchable mask layer on the stretchable substrate;
• forming a stretchable mask pattern having an opening region and a closing region by patterning the stretchable mask layer;
• forming a low stretchable region and a high stretchable region having a modulus lower than a modulus of the low stretchable region on the stretchable substrate through the opening region and the closing region of the stretchable mask pattern;
• forming a driving element for controlling a light emitting layer of a pixel on the low stretchable region and forming a wiring for applying an electrical signal to the driving element on the high elastic region, in which the wiring is formed on the stretchable mask pattern forming the closing region;
• and
• forming the light emitting layer electrically connected to the driving element to emit light.

A method of manufacturing a stretchable substrate structure, the method comprising:

• forming a stretchable mask layer on a stretchable substrate;
• forming a stretchable mask pattern having an opening region and a closing region by patterning the stretchable mask layer;
• and
• forming a hybrid stretchable substrate by forming a low stretchable region and a high stretchable region having a modulus lower than a modulus of the low stretchable region on the stretchable substrate through the opening region and the closing region of the stretchable mask pattern.
