Abstract
A method for preparing an organic light emitting diode, comprising the following steps: providing a substrate, the surface of the substrate has a plurality of first electrodes; depositing a first organic material layer on the surface of the substrate provided with a plurality of first electrodes; providing A template with nano-patterns, the nano-patterns include a plurality of recesses with different depths; attach the surface of the template with nano-patterns to the first organic material layer, and extrude the template and the first organic material layer; releasing the template from the first organic material layer, transferring the nano-pattern to the first organic material layer, and forming protrusions with different heights on the surface of the first organic material layer away from the substrate structure; depositing an organic light-emitting layer on the surface of the raised structure of the first organic material layer away from the substrate; depositing a second organic material layer on the organic light-emitting layer; and forming a second electrode and the second organic The material layers are electrically connected.
Description
technical field [0001] The invention relates to a preparation method of an organic light emitting diode. Background technique [0002] Organic light emitting diode (OLED) is a light-emitting diode whose light-emitting layer is composed of organic compounds. As an efficient light source, it has many characteristics such as light weight, thin thickness, multi-color, and low manufacturing cost , making organic light-emitting diodes gradually show a tendency to replace traditional light-emitting diodes in the lighting application of large-area surface light sources, and have been widely used in various fields. [0003] However, the preparation of the OLED in the prior art needs to be carried out in a vacuum system, and the mask needs to be replaced at least three times, the process is complicated and the cost is high; The organic material layer causes damage, thereby affecting the luminous effect of the OLED and the lifespan of the OLED. Contents of the invention [0004] In...
