    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.

  • Patent number: 12259618
    Abstract: A display panel and a display module are provided. The display panel includes a non-display area, a central display area, and a peripheral display area arranged between the two areas. A counterpart substrate is arranged opposite to an array substrate, with a liquid crystal layer positioned between the array substrate and the counterpart substrate. A meta-surface structure layer of the counterpart substrate is arranged in the peripheral display area. Light emitted from the peripheral display area is at least partially deflected by the meta-surface structure layer and then emerges from the non-display area. The meta-surface structure layer in the peripheral display area alters the propagation path of light, allowing at least part of the light emitted from the peripheral display area to enter the non-display area. This approach overcomes the limitations imposed by a frame, enlarges the display area of the display panel, and achieves a narrow-frame display panel.
