Embodiment 1

[0034] Please refer to figure 1 , the light-emitting device 100 according to Embodiment 1 of the present invention includes a substrate 110, an organic light-emitting element 120 disposed on the substrate 110, an inorganic material layer 130 covering the organic light-emitting element 120, an organic material layer 140 covering the inorganic material layer 130, and an organic light-emitting element covering the organic light-emitting element 120. The resin film layer 150 of the material layer 140 , and the inorganic sealing layer 160 covering the resin film layer 150 .

[0035] In this embodiment, the inorganic material layer 130 is deposited on the organic light-emitting element 120 first, wherein the inorganic material can be inorganic nitride or inorganic oxide, such as aluminum oxide, silicon oxide, silicon nitride, zirconium oxide, and titanium oxide. The organic material layer 140 is arranged on the inorganic material layer 130, which is adjacent to the resin film layer ...

Embodiment 2

[0046] Please refer to image 3 , the light-emitting device 200 of Embodiment 2 of the present invention includes a substrate 210, an organic light-emitting element 220 disposed on the substrate 210, an inorganic material layer / organic material layer 230 covering the organic light-emitting element 220, an inorganic material layer / organic material layer 230 covering the The resin film layer 250, and the inorganic sealing layer 260 covering the resin film layer 250.

[0047] In this embodiment, the only difference from Embodiment 1 is: In the inorganic material layer / organic material layer 230, the inorganic material layer and the organic material layer are alternately arranged in multiple layers, all of which are more than two layers, multi-layer inorganic material layers The organic material layer can further improve the encapsulation effect. In addition, the manufacturing process of the light-emitting device 200 is the same as that of the light-emitting device 100 , the only...

Embodiment 3

[0050] Please refer to Figure 4 , the light-emitting device 300 of Embodiment 3 of the present invention includes a substrate 310, an organic light-emitting element 320 disposed on the substrate 310, an inorganic material layer / organic material layer 330 covering the organic light-emitting element 320, an inorganic material layer / organic material layer 330 covering the The resin film layer 350, and the inorganic sealing layer 360 covering the resin film layer 350.

[0051] The structure of the light emitting device 300 is similar to that of the light emitting device 200 , the difference is that in Embodiment 3, a transparent water absorbing layer 370 is provided between the resin film layer 350 and the inorganic material layer / organic material layer 330 . The transparent water-absorbing layer 370 is made of transparent water-absorbing materials such as acrylic resin or silicon monoxide, which can absorb a small amount of water vapor entering the resin film layer 350, thereby ...

Abstract

The present invention relates to a light-emitting device and a packaging method thereof, wherein the light-emitting device includes a substrate and organic light-emitting elements arranged on the substrate, and further includes inorganic material layers and layers of inorganic materials alternately arranged on the substrate and covering the organic light-emitting elements. An organic material layer, a resin film layer covering the inorganic material layer and the organic material layer, and an inorganic sealing layer covering the resin film layer. In the present invention, on the inorganic / organic film formed by the inorganic material layer and the organic material layer, a resin film layer is also provided. The resin film layer has a good full coverage effect, which can well make up for the poor performance of the inorganic / organic film. Particle defects such as dust are covered, and an inorganic sealing layer is further provided on the resin film layer to reinforce the poor sealing effect of the resin film layer. Therefore, the influence of external particles such as dust on the encapsulation effect can be eliminated or weakened, and the yield rate and encapsulation effect of thin film encapsulation can be improved.

Description

technical field [0001] The invention relates to the field of manufacturing organic light emitting devices, in particular to an organic light emitting device and a packaging method thereof. Background technique [0002] Flexible OLED (FOLED) has the advantages of wide viewing angle and high brightness of ordinary OLED. At the same time, because the substrate of FOLED is a material with good flexibility, it is lighter, thinner and more impact-resistant than glass-substrate OLED display. Moreover, the preparation of FOLED is expected to be produced in a roll-to-roll manner, thereby greatly reducing the manufacturing cost. However, the existing glass encapsulation methods cannot correspond to FOLED encapsulation. [0003] There are two traditional packaging methods for flexible organic optoelectronic devices. [0004] (1) One is thin-film encapsulation technology, such as Vitex's Barix technology, in which thin-films are formed by layers of inorganic-organic materials (a few m...
