Problems solved by technology

[0003] The sealant in contact with OLED generally needs to ensure low viscosity and high water resistance at the same time, so as to maintain good packaging characteristics without damaging the device. However, both low viscosity and high water resistance are actually often It is contradictory. It is difficult for a sealing material to have the above two properties at the same time.

Abstract

The invention relates to an organic light emitting diode (OLED) display panel and a manufacture method thereof. The manufacture method includes providing a first substrate and a second substrate, wherein an OLED layer is formed on the first substrate; coating a first sealant on the surface of the OLED layer located on the first substrate; coating a second sealant on the surface of the second substrate, and coating a third sealant on the periphery, located in the second sealant, of the second substrate, wherein the viscosity of the first sealant is smaller than that of the second sealant; laminating and solidifying the first substrate and the second substrate so that the second sealant covers the first sealant and fills a gap between the first and second substrates and the third sealant. By means of the OLED display panel and the manufacture method thereof, tension of contact surfaces of the sealants and an OLED during a solidifying process can be reduced, damages to the OLED are reduced, and meanwhile, good water-tightness of a sealing structure of the OLED can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of OLEDs, in particular to a method for manufacturing an organic light emitting diode display panel and an organic light emitting diode display panel. Background technique [0002] Organic electroluminescent display devices have favorable characteristics such as active light emission, wide viewing angle, high contrast ratio, and fast response speed, and are known as a new generation of display technology. The basic structure of an organic EL device generally includes: a substrate, a first electrode layer, a second electrode layer, a light-emitting layer, and a cover plate. The EL device on the substrate is sealed by a cover plate and a sealant to prevent deterioration of device performance and lifetime due to external environment (water, oxygen). [0003] The sealant in contact with OLED generally needs to ensure low viscosity and high water resistance at the same time, so as to maintain good packag...
