<p indent="0mm">The technology of LTPS–AMOLED has been widely used in the field of flexible displays, but due to the limitations of brittle films, it cannot be directly applied in the field of stretchable displays. In this paper, the stretchable display device with island–bridge structure is prepared based on LTPS–AMOLED technology and hollow technology. To ensure that the stretchable display has good stretchable properties, the influencing factors affecting stretchable properties are studied in this paper. Firstly, by researching the stretchable deformation mechanism, it is found that reducing the bridge width, increasing the length of the bridge, reducing the angle and appropriately increasing the radius of the stretchable structure can better release the stress strain. Secondly, the research has shown that tensile strain, compressive strain and neutral position will occur above the bridge when the stretchable display was stretched, and when the metal was placed in the neutral position or the compressive strain position, the fractures will be effectively reduced. The induced cracks which were caused by the fracture of the inorganic layer above the bridge will be enhanced with the increase of the film thickness. The organic layer can block the induced cracks and the barrier effect is enhanced when the thickness of the organic layer is increased. By reducing the thickness of the inorganic layer above the bridge and increasing the thickness of the organic layer, the induced crack of the inorganic layer can be effectively reduced. At last we prepared a 2.3-inch OLED stretchable display, and the stretch volume in the horizontal direction can reach more than 5%.
