Abstract
Recently, mechanically deformable displays, such as flexible, foldable, rollable, and stretchable displays, have
received considerable attention due to their broad range of applications across various electronic systems. Among
the various types of deformable displays, stretchable displays represent the most advanced form factor. The
stretchable displays require a sophisticated integration of components, including stretchable conducting,
insulating, and semiconducting materials, intricate geometrical patterns, and multiple electronic elements. This
comprehensive review explores the recent progress in stretchable displays, emphasizing the critical developments
in materials, device architectures, and practical applications. Key innovations in stretchable electrodes and
interconnections, light-emitting materials, transistors, circuitry, and deformable substrates are explored,
highlighting their contributions to enhancing durability and stretchability. Also, the review highlights the latest
research on achieving stretchability using intrinsically elastic materials or through structural engineering with rigid
materials. Additionally, we introduce innovative applications of stretchable displays in various emerging electronic
systems.
Keywords: Stretchable displays, structure engineering, intrinsic stretchability, conductors, semiconductors, light-
emitting layers, substrates
