Abstract:
The present invention provides an OLED encapsulation method and an OLED encapsulation structure. By arranging at least two loops of encapsulation resin frames around an outer circumference of the OLED device, the potential risk of external moisture and oxygen invading can be greatly reduce, and even one of the multiple loops of the encapsulation resin frames appears a defect spot, no influence would occur on the OLED device located internally. Further, by arranging a single or multiple encapsulation resin connection sections between two adjacent loops of the encapsulation resin frames, multiple discontinuous sealed and enclosed spaces are formed between two adjacent loops of the encapsulation resin frames so as to effectively block moisture and oxygen to flow among different ones of the sealed and enclosed spaces, whereby a defect spot occurring in any one of the encapsulation resin frames could only affect the sealed and enclosed space where the defect spot is located and would not affect the sealed and enclosed spaces of other sites so as to better block the invasion of external moisture and oxygen to the OLED device and thus improving encapsulation effectiveness of the OLED device. Based on the two features discussed above, the present invention may overcome the issue of invasion of moisture and oxygen resulting from defect spot caused by aging of an encapsulation resin frame and significantly improving light emission quality and service life of the OLED device.

The present invention provides an OLED encapsulation glovebox, which includes a plurality of spaced sealing rings between a box body and a box door to allow the box body, the box door, and the plurality of sealing rings to collectively enclose and delimit therebetween a plurality of sealed spaces between adjacent ones of the sealing rings and positive pressures are maintained in the plurality of sealed spaces to block entry of external moisture and oxygen into the interior of the box body. Compared to the arrangement of the known OLED encapsulation glovebox that keeps a positive pressure in the interior of a box body to prevent entry of external moisture and oxygen, the present invention helps lower down the cost for maintaining positive pressure and provides multiple protection barriers for the internal environment of the box body by arranging a plurality of sealing rings so as to effectively eliminate the situation that invasion of external moisture and oxygen may occur due to breaking or damage of the arrangement of just one single sealing rings.
