1. A display panel, the display panel comprising a display area and a frame area, and the frame area surrounding the display area; and the display panel being a liquid crystal display panel;
wherein the display panel comprises an array substrate, a plurality of light-emitting units, a plurality of driving lines electrically connected to the light-emitting units, and a opposite substrate; the plurality of light-emitting units are arranged in an array on a surface of the display panel corresponding to the frame area so as to at least partially cover a surface of the frame area of the display panel; a portion of the opposite substrate corresponding to the display area is arranged with sub-pixel units; the array substrate comprises a driving circuit layer, and at least part of the driving lines electrically connect with the driving circuit layer so that the drive circuit layer drives the light-emitting units while the drive circuit layer drives the sub-pixel units;
wherein the array substrate is disposed on a light-emitting side of the display panel; the array substrate further includes a base substrate, and the driving circuit layer and the base substrate are sequentially stacked along a light-emitting direction; the light-emitting units and the driving lines are arranged on a light-emitting surface of the base substrate; each of the driving lines is arranged with ones of the plurality of light-emitting units thereon; a portion of the base substrate which is at the frame area is defined with via holes extending from the light-emitting surface to the driving circuit layer and further comprises connection lines passing through the via holes; and at least part of the driving lines electrically connect with the driving circuit layer through the connection lines which are arranged one-to-one corresponding to the ones of the plurality of light-emitting units.
