Abstract
A display panel includes a drive backplane, the drive backplane being provided with a binding layer for fixing a light-emitting chip, and the display panel further includes a photoresistor disposed on a surface of the drive backplane and arranged close to the binding layer, the photoresistor having a resistance for being increased when the light-emitting chip is in an abnormal state, and the binding layer being configured to be in a molten state under an action of heat generated by the photoresistor when the light-emitting chip is in the abnormal state. The technical solution of the present application can reduce the damage of the binding layer and ensure that the normal light-emitting chip can be effectively repaired and replaced.
