[0049] Please refer to FIG. 3 , an organic electroluminescent device 2 according to a preferred embodiment of the present invention includes a substrate 21 , at least one organic electroluminescent element 22 and a packaging unit 23 .

[0050] The substrate 21 includes at least one first recessed area 211 adjacent to an edge of the substrate 21. In this embodiment, as shown in FIG. It is adjacent to the periphery of the substrate 21 , so that the peripheral thickness of the substrate 21 is smaller than other parts of the substrate 21 . The substrate 21 is selected from at least one of rigid substrates, flexible substrates, glass substrates, plastic substrates, and silicon substrates, and the material of the substrate 21 is selected from at least one of polymethylmethacrylate, plastic, polymer, glass, and silicon. one.

[0051] Please refer to FIG. 3 , the organic electroluminescent element 22 includes a first electrode 221 , at least one organic functional layer 222 and a sec...

[0058] Please refer to FIG. 7 , an organic electroluminescent device 4 according to a preferred embodiment of the present invention includes a substrate 41 , at least one organic electroluminescent element 42 and a packaging unit 43 .

[0059] Since the components, materials, arrangement relationships and functional features of the substrate 41 and the organic electroluminescence element 42 in this embodiment are the same as those described in the first embodiment, they are not repeated here.

[0060] In this embodiment, the encapsulation unit 43 covers the organic electroluminescent element 42 and includes a cover plate 431 and an adhesive 432. The cover plate 431 includes at least one first recessed area 433 adjacent to the cover plate 431. On the edge, as shown in FIG. 7 , the first recessed area 433 is adjacent to the periphery of the cover plate 431 , so that the distance D2 between the substrate 41 and the first recessed area 433 of the cover plate 431 is greater than 15 ...

Abstract

The disclosed organic electroluminescence (OEL) device comprises: a substrate including at least one first concave area near its edge; at least one OEL element, including a first electrode, at least one organic function layer, and a second electrode; and a package unit including a cover plate and the adhesive, wherein the adhesive is partial accommodated in the first concave area to connect the cover plate and substrate. The corresponding preparation method comprises: in turns, preparing the OEL element and the concave area, and packing the product.

Description

technical field [0001] The invention relates to an organic electroluminescence device and a manufacturing method thereof, in particular to an organic electroluminescent device applied to thinning of a substrate or a cover plate and a manufacturing method thereof. Background technique [0002] Organic electroluminescent apparatus (organic electroluminescent apparatus) has the advantages of self-illumination, no viewing angle limitation, power saving, simple manufacturing process, low cost, wide operating temperature range, high response speed and full color, etc., making it a great potential, it is expected to become the mainstream of flat-panel display devices in the new era. [0003] Organic light-emitting devices are devices that use the self-luminous properties of organic functional materials to achieve display effects. They can be classified into small molecule organic light-emitting devices (small molecule OLED, SM- OLED) and polymer light-emitting device (polymer ligh...
