摘要：
A light emitting diode, a display substrate and a transfer method are disclosed. The transfer method includes: disposing a display substrate on an adsorption carrier plate, and absorbing, by a transport head, multiple light emitting diodes from a donor substrate; dropping, by the transport head, the multiple light emitting diodes onto the display substrate, the light emitting diodes falling into positioning holes on the display substrate; and absorbing and removing, by the transport head, a light emitting diode on the display substrate which does not fall into a positioning hole.
