Abstract

The invention discloses an OLED device cathode and display panel making method, a display panel and a display device. The organic electroluminescent device cathode making method comprises steps that a cathode material is dissolved in a solvent containing fluorine compound to form dispersed suspension; the dispersed suspension is formed on a substrate, and the solvent of the dispersed suspension is volatilized to form a cathode layer. The cathode making method is advantaged in that utilizing a solution method to make a cathode is realized, adverse influence caused by utilizing a cavity coating method to make the cathode is avoided, making cost is relatively low, the method is applicable to the substrate in various specifications or prepared by various materials, for example, glass, plastic, metal or silicon materials can be utilized to make the substrate, the solvent containing the fluorine compound has no adverse influence on an organic layer of an organic electroluminescent device, process butt joint with an organic film layer of the solution method can be easily realized, and batch production of the organic electroluminescent device can be easily realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an organic electroluminescent device cathode and a display panel, a display panel and a display device. Background technique [0002] In the field of display, Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. [0003] At present, in the manufacturing process of OLED devices, the organic layer can be made by a solution method, but the cathode needs to be made by a cavity coating method, such as a vacuum evaporation method or a physical vapor deposition (Physical VaporDeposition, PVD) method. Both manufacturing processes need to be carried out in a vacuum chamber, so the solution method cannot be used to make OLED devices in the prior art. In the process of making OLED devices, ...
