Problems solved by technology

[0005] The bidirectional light-emitting device driven by alternating current in the prior art lights up the device by switching positive and negative currents, but its (hole injection layer) HIL and (electron injection layer) EIL are doped according to a certain ratio to achieve both Injecting electrons can also inject holes. When (hole injection layer) HIL and (electron injection layer) EIL are doped together, some reactions may occur, hindering the injection of electrons or holes, so its carrier injection ability is very weak, it is very difficult to realize the AC-driven OLED device

Abstract

The invention discloses an OLED manufacturing method and an OLED. The OLED comprises an anode, a cathode and an organic function layer disposed between the anode and the cathode. The organic function layer comprises a first injection layer, a first transmission layer, at least one light emitting layer, a second transmission layer and a second injection layer which are stacked successively. The first injection layer comprises at least one first hole injection strip and at least one first electron injection strip which are arranged in a parallel, alternative and connected mode. The second injection layer comprises at least one second hole injection strip and at least one second electron injection strip which are arranged in a parallel, alternative and connected mode. The at least one second electron injection strip and the at least one second electron injection strip are arranged opposite to the at least one first hole injection strip and the at least one first electron injection strip respectively. Single-color or white light areas corresponding to the at least one first hole injection strip are lightened through alternating-current electricity, after positive and negative electrodes are switched, the single-color or white light areas corresponding to the at least one first electron injection strip are lightened within short time, and accordingly, the time is short, and human can only see the whole single-color or white light emitting layer through eyes.

Description

technical field [0001] The invention relates to the fields of display and lighting, in particular to a method for manufacturing an organic electroluminescent device (OLED device) and the OLED device. Background technique [0002] Organic Light-Emitting Diodes (OLED for short) is a self-luminous device, which has light weight, ultra-thin, high theoretical luminous efficiency, and more importantly, it can be made flexible, whether it is lighting or display, It will be the direction of future development. [0003] The efficiency and lifespan of organic light-emitting materials have been greatly improved. Especially in recent years, the photoelectric properties of red and green organic light-emitting materials have fully met the requirements of industrialization, but the efficiency of blue light materials is still very low, and the lifespan is still very low. It is also very low, especially in the case of high voltage and long-time lighting devices, the life and efficiency deca...
