Abstract: Provided are an array substrate, a display panel and a display device, relating to the field of display technology. The array substrate includes a pixel disposition region including multiple pixel regions arranged along a first direction and a second direction. The first direction intersects the second direction. The pixel disposition region includes a first region and a second region that each includes at least one pixel region. The array substrate further includes a substrate and marks located on one side of the substrate and in the pixel disposition region. In the first region, marks of the at least one pixel region are a first arrangement pattern, and in the second region, marks of the at least one pixel region are a second arrangement pattern. The first arrangement pattern is different from the second arrangement pattern.

Abstract: A display device is provided. The display device includes a first display panel and a second display panel stacked in a first direction. The first display panel includes a first substrate, and light-emitting units on a side of the first substrate away from the second display panel. The light-emitting units include first light-emitting units and second light-emitting units. One first light-emitting unit includes a first light-emitting layer, and a distance between the first light-emitting layer and the first substrate in the first direction is D1. One second light-emitting unit includes a second light-emitting layer, and a distance between the second light-emitting layer and the first substrate in the first direction is D2, where D1>D2. The second display panel includes a reflective surface on a side of the first substrate away from the light-emitting units.

Abstract: Provided are a display panel and a display device. The display panel includes a plurality of sub-pixels. The plurality of sub-pixels includes at least one first color sub-pixel, one of which includes M first wirings connected in parallel. The M first wirings include at least one first sub-wiring, and each first sub-wiring includes N light-emitting diodes (LEDs) connected in series, where M and N are positive integers, M?2, and N?2.

Abstract: A display panel and a method for manufacturing the display panel and a display apparatus are provided. In an embodiment, the display panel includes a substrate, a first connecting electrode provided on a side of the substrate, and a light-emitting device including at least one second connecting electrode. In an embodiment, conductive particles are provided between the second connecting electrode and the first connecting electrode. In an embodiment, the first connecting electrode and the light-emitting device are connected by a connecting structure. In an embodiment, the connecting structure is provided between the first connecting electrode and the second connecting electrode, and/or, the connecting structure is provided on a sidewall of the first connecting electrode and a sidewall of the second connecting electrode.
