Stretchable display panel, method of fabricating stretchable display panel, and display apparatus

A stretchable display panel, comprising:

• a stretchable base substrate;
• a supporting structure comprising a plurality of islands and a plurality of bridges on the stretchable base substrate;
• a plurality of display elements respectively on sides of the plurality of islands away from the stretchable base substrate;
• and
• a plurality of signal lines respectively on sides of the plurality of bridges away from the stretchable base substrate, a respective one of the plurality of signal lines connecting two adjacent display elements;
• wherein the plurality of islands are arranged in a form of an array;
• the plurality of bridges comprise a plurality of row bridges arranged in a row direction and a plurality of column bridges arranged in a column direction;
• two directly adjacent islands in a same row of islands are connected by a respective one of the plurality of row bridges;
• two directly adjacent islands in a same column of islands are connected by a respective one of the plurality of column bridges;
• at least a portion of a respective one of the plurality of bridges is buckled when substantially unstretched;
• at least a portion of the stretchable base substrate in a region corresponding to the respective one of the plurality of bridges is buckled when substantially unstretched;
• the plurality of islands comprise a plurality of first supports on the stretchable base substrate, and a plurality of second supports respectively on sides of the plurality of first supports away from the stretchable base substrate;
• thicknesses of the plurality of first supports are greater than thicknesses of the plurality of second supports;
• the plurality of second supports and the plurality of bridges forms a unitary structure;
• and
• the thicknesses of the plurality of second supports and thicknesses of the plurality of bridges are substantially the same.
