Embodiment Construction

[0020] As mentioned in the background technology, the light-emitting layer in the light-emitting device in the prior art is printed by inkjet, but the luminous efficiency of the light-emitting layer is low and the service life is short. The arrangement of the organic light-emitting materials in the light-emitting layer formed by ink printing is disordered, which leads to the decrease of the mobility of electrons and holes in the organic light-emitting materials, thus reducing the luminous efficiency of the light-emitting layer and shortening the service life of the light-emitting layer .

[0021] Based on this, the present invention provides a method for preparing a light-emitting device. An auxiliary agent is added to the ink used for inkjet printing of the light-emitting layer, and the auxiliary agent can be aligned under light irradiation, so that the organic light-emitting material The van der Waals force between the organic molecules and the auxiliary molecules enables th...

Abstract

The invention provides a preparation method of a luminescent device as well as the luminescent device and a display panel and solves the technical problems that an organic luminescent layer formed byadopting ink-jet printing in the prior art is low in luminescence efficiency and short in life. The preparation method provided by the embodiment of the invention sprays an organic luminescent material on one surface of an anode by adopting an ink-jet printing manner, and ink used for ink-jet printing is added with auxiliaries which can be directionally arranged by irradiation of light, so that Van der Waals' force between organic molecules in the organic luminescent material and auxiliary molecules enables the organic luminescent material to also be directionally arranged as the auxiliaries can be directionally arranged by the irradiation of light, migration rate of electrons and holes in the organic luminescent material is increased, and then the luminescence efficiency of the luminescent device is improved and the service life of the luminescent device is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a light emitting device, a light emitting device and a display panel. Background technique [0002] Because inkjet printing technology has the advantages of simple process and low cost, this technology has become one of the conventional choices for preparing organic light-emitting layers in OLED light-emitting devices. However, most organic light-emitting layers produced by inkjet printing have the problems of low luminous efficiency and short lifespan, which seriously hinders the popularization of inkjet printing technology. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a method for preparing a light-emitting device, a light-emitting device, and a display panel, which solve the technical problems of low luminous efficiency and short service life of the organic light-emitting layer formed by inkjet p...
