Title:
ANODE WITH HOLE TRANSDPORT FUNCTION AND ORGANIC LIGHT-EMITTING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/104848
Kind Code:
A1
Abstract:
An anode (10) with a hole transport function and an organic light-emitting display device. The anode comprises an electrode layer (1) and a composite layer (2) manufactured on the electrode layer (1), wherein the composite layer (2) comprises a transparent electrode material and a doped material formed into the electrode material in a doped manner; a HOMO energy level of the doped material is lower than that of the electrode material; and the HOMO energy level of the composite layer (2) on one side, close to the electrode layer (1), is higher than the HOMO energy level of the composite layer on one side that is far away from the electrode layer (1). The anode (10) also has a hole transport function, and a doped material therein is formed into a transparent electrode material in a doped manner, so that the problem of a low hole transport efficiency due to a HOMO energy level mismatch between the anode (10) and a hole injection layer is solved, and the hole transmission efficiency and the light-emitting efficiency of an OLED device are improved; moreover, since the hole injection layer is omitted, the anode (10) of an organic light-emitting display device can be in direct contact with a hole transport layer, so that the distance between the anode (10) and a cathode is reduced, and the light-emitting efficiency can thus be prevented from being affected by a microcavity effect.
