Method of encapsulating organic light emitting display device

1. A method of encapsulating an organic light emitting display device, comprising:

preparing an encapsulating substrate to encapsulate a lower substrate on which a display unit is arranged, the display unit includes the organic light emitting display device;

forming a black mask on portions of the encapsulating substrate that do not correspond to a sealant region;

applying a first sealant onto the encapsulation substrate within the region where the black mask is not formed and on the surface of the encapsulation substrate that the black mask is arranged; and

applying a second sealant onto the first sealant and within the sealant region where the black mask is not formed, the second sealant comprising a fluoride, the second sealant is applied directly onto the first sealant.

2. The method of claim 1 , wherein the first sealant is a primer layer and includes a vinyl resin, the second sealant being an ultraviolet hardening epoxy resin that includes a fluoride.

3. The method of claim 1 , wherein each of the first sealant and the second sealant are applied via a squeezing process.

4. The method of claim 1 , further comprising annealing the first sealant upon said application of the first sealant and prior to said application of the second sealant.

5. The method of claim 1 , further comprising:

removing the black mask;

combining the encapsulating substrate to the lower substrate; and

hardening the first and second sealants by using a UV ray.

6. The method of claim 1 , further comprising annealing the first sealant prior to the applying of the second sealant, wherein the second sealant is a UV hardening epoxy resin arranged only on the annealed first sealant.

7. A method of encapsulating an organic light emitting display device, the method comprising:

preparing an encapsulating substrate to encapsulate a lower substrate on which a display unit, which includes the organic light emitting display device, is formed;

forming a black mask on a region of the encapsulating substrate, which is not a sealant region and corresponding to outer regions of the display unit;

forming a first sealant on the encapsulation substrate and in the sealant region and a second sealant onto the first sealant, wherein the forming of the first and second sealants comprise:

coating the first sealant in the sealant region;

annealing the first sealant; and

coating the second sealant onto the annealed first sealant, wherein the second sealant is a UV hardening epoxy resin arranged only on the annealed first sealant.

8. A method of encapsulating an organic light emitting display device, comprising:

preparing an encapsulating substrate to encapsulate a lower substrate on which a display unit is arranged, the display unit includes the organic light emitting display device;

forming a black mask on all portions of a surface of the encapsulating substrate outside of a sealant region;

applying a first sealant onto a portion of the surface of the encapsulation substrate that corresponds to the sealant region, the first sealant being absent of a fluoride;

annealing the first sealant;

applying a second sealant onto the annealed first sealant and within the sealant region, the second sealant including a fluoride, wherein the second sealant is applied directly to the first sealant and is in direct contact with the lower substrate;

removing the black mask from the encapsulating substrate;

combining the lower substrate with the encapsulating substrate together; and

hardening the first and second sealants via exposure to UV radiation, wherein the black mask does not serve as an exposure mask during the hardening.

9. The method of claim 8 , the first sealant being a vinyl resin and being a primer layer for the second sealant.

10. The method of claim 8 , wherein the application of the first and second sealants is by a squeezing technique using the black mask as a pattern.

11. The method of claim 8 , wherein the second sealant is arranged only on the annealed first sealant.
