Light-emitting substrate and display device

Abstract

A light-emitting substrate includes a light-emitting region and a bonding region. The light-emitting region includes multiple lamp regions arranged in multiple rows and columns. Each row includes at least two lamp regions arranged along a first direction, and each column includes at least two lamp regions arranged along a second direction. The bonding region is located on one side of the light-emitting region along the second direction. The light-emitting region includes a central region and an edge region located on at least one side of the central region. The lamp regions located in the central region are called central lamp regions, and the lamp regions located in the edge regions are called edge lamp regions. The light-emitting substrate also includes a bonding portion, a device power signal line, a driver chip, and multiple light-emitting devices. The device power signal line is connected to the bonding portion. The driver chip is disposed between two adjacent columns of lamp regions. The driver chip includes a driver pin. Multiple light-emitting devices are disposed in the lamp regions. One end of a light-emitting device in a lamp region is coupled to the same driver pin, and the other end is coupled to the device power signal line. The number of multiple light-emitting devices in the central lamp region is not equal to the number of multiple light-emitting devices in the edge lamp regions.
