[0044] FIG. 1 is a schematic diagram of the steps of spraying a dewatering agent according to a first embodiment of the present invention.

[0045] Referring to FIG. 1 , in step 100 , a substrate is provided, wherein the substrate can be a plane or a substrate with grooves. Then, in step 102, inkjet printing is used to spray desiccant on the substrate. In this embodiment, more than one inkjet head or similar device can be used to directly print A water remover with a high surface area pattern is sprayed on it, and the water remover can be sprayed on a flat substrate or a substrate with grooves, and the water remover can be thermosetting or UV curing. Next, proceed to step 104, curing the water-removing agent; if the water-removing agent is a thermosetting type, then curing the water-removing agent is performed by heating; if the water-removing agent is an ultraviolet curing type, then curing the water-removing agent is performed by a Appropriate wavelength, appropriate time o...

[0048]The invention can be applied in the process of display elements and light source elements of organic electroluminescent elements. In this embodiment, the present invention is applied to the packaging process of organic electroluminescent elements, as shown in FIG. 2 . Mainly, the preparation of the cover part and the preparation of the organic light emitting diode (OLED for short) substrate are carried out separately, and then the two are combined to achieve the packaging process of the components.

[0049] FIG. 2 is a schematic diagram of packaging steps of an organic electroluminescence device according to a second embodiment of the present invention.

[0050] In step 200, the alignment of the cover is to align an inkjet head or similar device for performing inkjet printing with the cover, wherein the cover can be flat or grooved glass, plastic or Flexible substrate. Then, in step 202, inkjet printing is used to spray the dewatering agent on the cover plate. This ste...

Abstract

The invention is a kind of organic electric laser element, organic electric laser element sealing method and the coating desk. It prints the hydraulic water eliminating agent onto a cover with ink-jet mode, forms a graph with high surface area. Then it completes the seal structure by matching with the organic electric laser element sealing method, in order to decrease the harden time of the water eliminating agent, and advance the humidity eliminating rate and the ability through increasing the surface area of the water eliminating agent.

Description

technical field [0001] The present invention relates to an organic electroluminescent element, a method for encapsulating the organic electroluminescent element and a coating machine thereof, in particular to a method for shortening the hardening time of the water remover and increasing the surface area of ​​the water remover. ) An organic electroluminescence element for promoting its moisture absorption rate and moisture absorption capacity, an organic electroluminescence element packaging method and a coating machine. Background technique [0002] Organic light emitting diode (OLED for short) is a component that uses the self-luminous properties of organic functional materials to achieve display effects. Its light-emitting structure is composed of a pair of electrodes and organic functional materials. According to the molecular weight of the organic functional material, it is divided into two categories: small molecule OLED (SM-OLED) and polymer light-emitting device (PLED...
