Abstract

A display panel includes a driving backplane, a plurality of detection pads, a light emitting function layer, and a flexible circuit board. The driving backplane has a pixel driving region and a peripheral region, and the peripheral region has bonding pads; an edge of the driving backplane is surrounded by a first section and a second section, and the bonding pads are located between the first section and the pixel driving region; a plurality of detection pads are disposed in and distributed along the second section; a light emitting function layer is disposed on the driving backplane and located in the pixel driving region; a flexible circuit board extends between the first section and the pixel driving region, and is bonded to the bonding pads; a first packaging layer is disposed on the light emitting function layer.
