摘要
The present application provides a flexible display panel, a manufacturing method of the flexible display panel, and an electronic device. The flexible display panel includes an elastic substrate, main pixel islands, and auxiliary pixel islands. When the elastic substrate is in a natural state, the main pixel islands enclose a light emitting side of the auxiliary pixel islands to receive the auxiliary pixel islands. When the elastic substrate is in a stretched state, the main pixel islands are away from the auxiliary pixel islands to expose the auxiliary pixel islands, and the auxiliary pixel islands cooperate with the main pixel islands for displaying images. Accordingly, the present application increases a pixel density of a stretched portion of the flexible display panel.

This application is a National Phase of PCT Patent Application No. PCT/CN2021/107206 having International filing date of Jul. 19, 2021, which claims the benefit of priority of Chinese Patent Application No. 202110729100.8 filed on Jun. 29, 2021. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety.
The present invention relates to a field of display technology and in particular, to a flexible display panel, a manufacturing method of the flexible display panel, and an electronic device.
With the development of the Internet of Things technology, more and more consumer electronics are indispensable in our daily lives. These consumer electronics usually need to realize not only two-dimensional plane of display, but also three-dimensional display. In order to meet more users' demands for display technology, stretchable display technology is created.
Conventional stretchable flexible display panels are usually provided with a plurality of pixel islands and a stretched portion connected between the pixel islands. Each pixel island comprises a pixel unit. When the flexible display panel is in a stretched state, the stretched portion is stretched and extends, and a spacing between the pixel islands is enlarged, so a pixel density of the stretched portion of the flexible display panel is reduced, resulting in lower display brightness of the flexible display panel, and poor quality of displayed images.
