Publication number: 20240049519Abstract: 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.Type: ApplicationFiled: July 19, 2021Publication date: February 8, 2024Applicants: Wuhan China Star Optoelectronics Technology Co., Ltd., Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Bingkun YIN, Li HU, Liang SUN
