Abstract

The invention provides a manufacturing method of an OLED display substrate. The method comprises the following steps: providing an underlayer substrate; forming a first electrode layer; forming an initial solid buffer layer on the first electrode layer, wherein a molecular formula of a material of the initial solid buffer layer has an azobenzene group, a HOMO energy level of the initial solid buffer layer is between -6eV and 4.5eV, and a LUMO energy level of the initial solid buffer layer is between -3eV and 2eV; illuminating the initial solid buffer layer by utilizing ultraviolet, so that the initial solid buffer layer is liquefied to a liquid buffer layer; illuminating the liquid buffer layer by utilizing visible light, so that the liquid buffer layer is solidified into a final solid buffer layer; and forming a luminescent functional layer by virtue of the final solid buffer layer. The invention also provides an OLED display substrate, an encapsulation method of a display apparatus and a display apparatus. The display apparatus is relatively high in yield.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a method for manufacturing an OLED display substrate, an OLED display substrate, a packaging method for a display device, a display device obtained by using the packaging method, and a display device comprising the OLED display substrate for display devices. Background technique [0002] OLED display devices have the advantages of fast response speed, thinness, etc., and are more and more popular among users. [0003] The OLED display device includes a plurality of light-emitting elements, and each layer of the light-emitting element is solid. During manufacture, defects such as stress or unevenness are prone to occur. Therefore, the display device may have poor display due to this. [0004] Therefore, how to reduce the display defects of OLED display devices has become a technical problem to be solved urgently in this field. Contents of the invention [0005] The o...
