Abstract:
The present invention relates to an organic light-emitting diode device with efficiency roll-up property, comprising: a first conductive layer, a hole injection layer, a host light-emitting layer, a guest light-emitting layer, an electron transportation layer, a second conductive layer, and an electron injection layer, wherein when the guest light-emitting layer is doped in the host light-emitting layer after being appropriately selected and the value of ∥ΔEHOMO|−|ΔELUMO∥ approaches to zero, such that the color light emitted by the host light-emitting layer performs the property of current efficiency roll-up.
