    Abstract: Provided are a flexible display panel and a flexible display device, in which a non-display area surrounds a display area. A concave area protrudes along a direction away from interior of display area. A convex area has a folding axis parallel to a first edge. The non-display area includes a fan-out area, in which lead wires are provided. Each lead wire has a first end and a second end. There are signal traces each extending along a first direction provided in display area. The signal traces are electrically connected to first ends of lead wires. The convex area and concave area are arranged along a second direction. The second direction intersects first direction. A driving chip is included, which is a ball grid array package driving chip and is arranged in concave area where lead wires are away from first edge and electrically connected to second ends of lead wires.

    Abstract: A display panel includes an array substrate with a plurality of electrode pads formed on it. At least one electrode pad comprises a first area, a second area, and a third area. The third area connects the first area and the second area, and the first area of at least one electrode pad is equipped with a light-emitting element. A width of the third area is smaller than a width of the first area and a width of the second area, and/or a melting point of the third area is lower than a melting point of the first area or a melting point of the second area. This display panel can save a significant amount of space, facilitating the integration of functional structures and addressing the technical issue of low efficiency of space utilization in the display panel.

    Abstract: A display panel and a display device are provided. In the first pixel unit region, an orthographic projection of the first light-shielding portion on the base covers an orthographic projection of at least one via hole on the base. Thus, the first light-shielding portion can shield the light which is emitted by the adjacent light-emitting element and reflected by the via hole. In addition, the first light-shielding portion can further shield the light which is emitted by the light-emitting element in the first pixel unit region to the via hole, to avoid reflecting the light to the adjacent pixel unit region by the via hole in the first pixel unit region. Therefore, the light crosstalk between adjacent light-emitting elements is reduced, and the display effect of the display device is improved.

    Abstract: A display panel, a display device and a manufacturing method of the display panel are provided. The display panel has a display area and a non-display area surrounding the display area and includes a substrate, an array layer, a display layer, and an encapsulation layer that are arranged sequentially, and an ink layer located in the non-display area and surrounding the display area. The ink layer includes a first ink layer and a second ink layer that are located in different layers. Each of an orthographic projection of the first ink layer on the substrate and an orthographic projection of the second ink layer on the substrate is a non-closed pattern surrounding the display area.

    Abstract: A touch liquid crystal display device includes a first substrate and a second substrate opposite to each other, and a liquid crystal layer disposed between the first and second substrates. The first substrate includes a touch layer disposed on a surface of the first substrate facing the liquid crystal layer, an insulating layer disposed on a surface of the touch layer and covering the touch layer, and a pixel array structure disposed on a surface of the insulating layer facing away from the touch layer. The touch layer is disposed between the pixel array structure and the first substrate. Only a filming process and a photoetching process of the touch layer and a deposition process of the insulating layer are additionally required to transform a non-touch liquid crystal display device to a touch liquid crystal display device.
