Embodiment Construction

[0041] The present invention proposes a sealing structure of an organic electroluminescence device (OELD), which can not only effectively prevent moisture from invading the light-emitting device, but also release the stress of the overall structure. The present invention will be further described in detail with a preferred embodiment below.

[0042] In addition, the organic light-emitting layer of the organic electroluminescent element can be divided into: a small molecule light-emitting diode based on dyes or pigments, called OLED (organic light-emitting diode); Molecule-based light-emitting diodes are called PLEDs (polymer light-emitting diodes). It should be noted that the sealing structure in the embodiment of the present invention can be applied to sealing OLED or PLED, and there is no special limitation here.

[0043] Please refer to image 3 , which shows a schematic diagram of the sealing structure of the organic electroluminescent device according to a preferred emb...

Abstract

Encapsulation structure for organic electroluminescence device (OELD) includes a base plate, an OELD, a soft protective layer, a moisture absorption layer, and a rigid protective layer. The OELD is setup on the base plate. The soft protective layer is on the base plate and covers on the OELD. The moisture absorption layer covers on the soft protective layer, and the rigid protective layer covers on the moisture absorption layer.

Description

technical field [0001] The invention relates to a sealing structure of an organic electroluminescent element, in particular to a sealing structure capable of preventing water vapor from entering the organic electroluminescent element and releasing stress. Background technique [0002] Organic electroluminescence device (organic electroluminescence device), compared with other flat-panel display technologies, has self-illumination, high brightness, wide viewing angle, high contrast, low power consumption, high-speed response, wide operating temperature range, high luminous efficiency, and manufacturing process The excellent characteristics such as simplicity make its product technology development widely attract the attention of the world. [0003] The traditional organic electroluminescence device has a multi-layer structure, mainly an organic light emitting layer is placed between the anode layer and the cathode layer to generate electroluminescence. A hole injection layer...
