  • Patent number: 12125854
    Abstract: The present application provides a display panel, a display device, and a manufacturing method of the display panel. The display panel includes a substrate, an insulating layer, and an interlayer dielectric layer that are sequentially stacked. The interlayer dielectric layer includes a first section located in the display area and a second section located in the fan-out area, and a hollowed groove is defined in the second section and filled with an elastic material. Therefore, a bending resistance of film layers in the fan-out area is improved, and a problem that the film layers in the fan-out area is easily broken after bending and binding processes of the display panel is prevented.

  • Patent number: 11930692
    Abstract: The present application provides a display panel, a display module, and a display device. A flexible substrate of the display panel includes a first flexible substrate and a second flexible substrate, and the first flexible substrate is provided with a first through-hole corresponding to a lighting path of an electronic component. Based on the first through-hole, light transmittance of the display panel is increased, so that electronic components such as a camera can be disposed below the display panel, and a narrow bezel design is realized.

  • Publication number: 20240016004
    Abstract: A display panel and a display device are provided. The display panel includes a pixel definition layer and an encapsulation layer. The pixel definition layer is provided with a plurality of concave portions, the encapsulation layer is provided on the pixel definition layer, the encapsulation layer is provided with a plurality of convex portions, and the convex portions and the concave portions are fitted with each other to form an interlocking structure, so as to improve an adhesion between the encapsulation layer and the pixel definition layer. Therefore, a risk of film debonding and separation among the encapsulation layer, the pixel definition layer, and the functional layer is reduced.

  • Patent number: 10963013
    Abstract: A display device includes a display panel and a flexible substrate. A first pad and a second pad are arranged on the display panel. The flexible substrate includes a first layer, a first insulating layer, and a second layer on a bending area. A first metal line is arranged in the first layer and connected to the first pad. A second metal line is arranged in the second layer and connected to the second pad. A straightened length of the first metal line is greater than that of the second metal line. The design of a double-layer metal line effectively improves the stress intensity of the metal line in the outer bending area. Therefore, the inner and outer double-line metal line in the bending area is balanced by force, so that the stability of the inner and outer double-line metal line is relatively uniform.

  • Patent number: 10795499
    Abstract: A display device includes a flexible display panel. The flexible display device includes a first display portion, a second display portion, and a bendable portion. The bendable portion is configured to be bendable to allow the first display portion and the second display portion to be located at different planes. A sensor is disposed in the flexible display panel and configured to detect whether the bendable portion is bending. A control module is disposed in the flexible display panel and electrically connected to the sensor. The control module enables the first display portion to display a first image and enables the second display portion to display a second image when the sensor detects that the bendable portion is bending.
