Abstract
A display panel includes an array substrate and light-emitting diodes including display light-emitting diodes. A display area includes sub-pixel regions including display sub-pixel regions and backup sub-pixel regions. In each of first and second directions, the display sub-pixel regions and the backup sub-pixel regions are arranged alternately. Display anode and cathode are provided in each display sub-pixel region. Backup anode and cathode are provided in at least one backup sub-pixel region. The display anode located in one display sub-pixel region is connected to the backup anodes of at least two backup sub-pixel region, and/or, at least two backup anodes provided in one backup sub-pixel region are electrically connected to the display anodes of at least two display sub-pixel regions, respectively. A positive pin of the display light-emitting diode is bonded to the display anode, and a negative pin thereof is bonded to the display cathode.
