Abstract

The embodiment of the invention relates to the technical field of display, and discloses a flexible display substrate. The flexible display substrate comprises a flexible substrate, multiple pixel islands located on the flexible substrate and inter-island connection lines for connecting adjacent pixel islands, wherein the inter-island connection line comprises a first wiring layer and a second wiring layer respectively connected to two adjacent pixel islands and a connection layer connected with the first wiring layer and the second wiring layer; and the connection layer comprises a pullable conductive material layer. The embodiment of the invention also provides a flexible display device and a flexible display substrate manufacturing method. According to the flexible display substrate, the display device and the manufacturing method thereof, the stretching properties of the inter-island connection lines can be enhanced, and the stretching reliability of the flexible display substrateis thus improved.

Description

Technical field [0001] The present 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 the information society, people have increased requirements for 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 manufactured based on rigid materials such as glass, and the size and shape of the display devices are fixed after they are produced, which cannot meet the use of multiple occasions and complex environments. Therefore, people have been focusing on researching flexible stretchable display devices for many years. Until 2017, Samsung Display took the lead in exhibiting the world's first stretchable display device based on AMOLED at...
