preparation example Construction

[0040] The present application also provides a preparation method of the organic light-emitting device. Such as Figure 4 Shown is a flow chart of the preparation process of the organic light-emitting device provided by an embodiment of the present application. Such as Figure 4 As shown, the preparation method 400 includes:

[0041] Step S410, preparing a cross-linked layer on the first functional layer, where the cross-linked layer includes a cross-linked material.

[0042] In step S420, a second functional layer is prepared on the cross-linked layer, and there is an energy level difference between the second functional layer and the first functional layer.

[0043] Due to the energy level difference between the second functional layer and the first functional layer, heat is generated between the first functional layer and the second functional layer during the lighting process. By setting the cross-linking material, due to the high stability of the cross-linking materia...

The organic light-emitting device comprises a first functional layer, a cross-linking layer and a second functional layer which are sequentially stacked, energy level difference exists between the first functional layer and the second functional layer, and the cross-linking layer comprises a cross-linking material.

Description

technical field [0001] The present application relates to the technical field of light-emitting devices, in particular to an organic light-emitting device, a preparation method thereof, and a display device. Background technique [0002] Organic light-emitting diodes have gradually occupied a place in the display field due to their advantages such as thinness, flexibility, high contrast, and wide color gamut. However, since organic light-emitting diodes are mostly composed of organic materials, the properties of the materials are easily affected by conditions such as high temperature, high humidity, and light, resulting in poor device stability. Contents of the invention [0003] In view of this, the embodiments of the present application provide an organic light-emitting device, a manufacturing method thereof, and a display device, so as to solve the problem of poor stability of the organic light-emitting device in the prior art. [0004] The first aspect of the present ...
