Abstract
The present disclosure relates to an OLED display panel and a manufacturing method of the same. The OLED panel includes an anode, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer and a cathode disposed on a substrate. The anode transporting holes to the hole injection layer, the holes penetrating the hole injection layer into the hole transport layer, the cathode transporting electrons to the electron transport layer. The electrons pass through the electron transport layer and enter the light-emitting layer. Magnetic particles are provided in the light-emitting layer and generate a magnetic field on the barrier layer where the hole transport layer and the light-emitting layer intersect to change trajectories of electrons and holes that fail to normally enter the barrier layer and rebound, moving it again to the blocking layer for bonding, thereby increasing the internal quantum efficiency of the OLED assembly.
