Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible display substrate, a display device and a preparation method thereof. Background technique [0002] With the development of an information society, people have increased demands on display devices for displaying images. Recently, various types of flat panel display devices have been developed, such as liquid crystal display devices, plasma display devices, and electrophoretic display devices. However, traditional display devices are made of rigid materials such as glass, and the size and shape of the display devices are fixed after production, which cannot be used in multiple occasions and complex environments. Therefore, people have been focusing on the research of flexible and stretchable display devices for many years. Until 2017, Samsung Display took the lead in exhibiting the world's first AMOLED-based stretchable display device at the International Display Week...
