Abstract
A light-emitting substrate includes a back plate, light-emitting regions arranged in an array and a bonding electrode group. The light-emitting regions are disposed on the back plate, and each light-emitting region is provided with at least one light-emitting group therein. The bonding electrode group is disposed on the back plate and includes a first bonding electrode and remaining bonding electrodes. A second power supply voltage terminal of a light-emitting group is electrically connected to a feedback signal line included in the light-emitting substrate, and the first bonding electrode is electrically connected to the feedback signal line. An impedance between the first bonding electrode and an adjacent one of the remaining bonding electrodes is larger then an impedance between two adjacent and consecutive ones of the remaining bonding electrodes.
