Problems solved by technology

However, since the cover glass and the substrate are in plane contact, if the two are uneven or there are foreign objects between them, the UV curing adhesive will not be completely pressed together during the pressing process, resulting in cracks or cracks. The phenomenon of air bubbles, and even if the UV curing adhesive that is fully pressed and opened is cured by ultraviolet light, it will shrink and form broken lines, which makes the internal organic materials bear the risk of being corroded by water and oxygen. , thus reducing the reliability of the OLED device packaging, thereby reducing the water and oxygen resistance of the OLED device and reducing the service life of the OLED device

Abstract

The packaging structure of the OLED device provided by the invention comprises a substrate formed with the OLED device and a packaging cover plate arranged on the substrate; Wherein the package coverplate is provided with a first groove and a second groove, and the second groove is arranged around the first groove, the OLED device is arranged in the first groove, and the second groove is providedwith an adhesive material so that the package cover plate and the substrate formed with the OLED device are adhered and fixed. As that first groove and the second groove are arrange on the package cover plate, and the adhesive material is arrange in the second groove, the purpose of improving the reliability of the package of the OLED device is achieved, thus improving the water and oxygen resistance of the OLED device, and prolonging the service life of the OLED device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a packaging structure of an OLED device and a display panel. Background technique [0002] At present, OLED (Organic Light Emitting Diode, organic light-emitting diode) realizes light emission by evaporating organic thin film materials and metal cathode materials on glass substrates coated with anode materials, but organic thin film materials are mainly sensitive to oxygen and water vapor in the atmosphere. , will fail due to chemical reactions, and the metal cathode material will also cause galvanic corrosion due to exposure to water vapor. Therefore, the OLED light-emitting area must be effectively isolated from water and oxygen by encapsulating the OLED device to prolong the working life of the OLED device. [0003] At present, the most commonly used encapsulation is mainly the ultraviolet (UV) curing sealant encapsulation method. However, since the cover glass and ...
