Abstract: 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.

Abstract: A display panel and a display device are provided, and a technical field in displays is related. The display panel includes an array substrate, a liquid crystal layer, a color filter layer, a sensor layer, a glass substrate, and a collimator mechanism. The sensor layer includes a plurality of fingerprint recognition units. The collimator mechanism is disposed on a side of the sensor layer away from the color filter layer. The display device includes the display panel. Display function, touch function, and fingerprint recognition function are integrated into one, by manufacturing the fingerprint recognition units on the glass substrate on the display panel. The cost and the module thickness are further optimized. A fingerprint recognition area is realized as a full-screen area, and fingerprints can be recognized at any position on the screen.
