Embodiment Construction
[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.
[0022] The so-called pixel island refers to the non-stretchable device part when the flexible display substrate is stretched for display. In order to protect the device, the position of the device is usually set as a whole, so it is called "pixel island". In the prior art, the metal wiring layer adopts a si...

The embodiment of the invention relates to the technical field of display, and discloses a flexible display base plate. The flexible display base plate comprises a flexible substrate, a plurality of pixel islands located on the flexible substrate and metal wiring layers connected with the pixel islands, and the metal wiring layers are arranged on the flexible substrate. The metal wiring layers comprise main body parts and connecting parts between the main body parts and the pixel islands; and the metal thickness of the connecting parts is greater than the metal thickness of the main body parts. The embodiment of the invention further provides a flexible display device and a fabrication method of the flexible display base plate. The embodiment of the invention provides the flexible displaybase plate, the display device and the preparation method of the flexible display base plate, so that the connections between the pixel islands and the metal wiring layers are not prone to breaking, and the reliability of the flexible display base plate during stretching is improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a flexible display substrate, a display device and a manufacturing method thereof. Background technique [0002] With the development of the information society, the display devices for displaying images have increased demands. 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. [0003] The screen body of a stretchable display device can be bent and stretched at a certain angle without damage, and it is easy to apply to a variety of complex environments, which makes the research on stretchable display technolog...
