Right magnet or electromagnet, do not carry out particular determination to its specific structure herein.The externally-applied magnetic field can be to the ball with magnetic material
The microballoon 21 of core 211 generates suction, and so as to which microballoon 21 to be fixed on the first inorganic layer 1, the direction S is magnetic field side in Figure 12
To.
The first solvent 200 can be made to evaporate by heating, thus the first solvent 200 on the first inorganic layer 1 of removal, and retain
Microballoon 21, to obtain buffer layer 2, as shown in figure 12.
It should be noted that by the thickness and microballoon 21 of the first solvent 200 on the first inorganic layer 1 of control the
Concentration in one solvent 200 can control the quantity of the microballoon 21 on the first inorganic layer 1, to form single-layer or multi-layer microballoon 21.
Certainly, in the other embodiment of the disclosure, microballoon 21 can also be laid with directly on the first inorganic layer 1, with
To buffer layer 2, and without the help of the first solvent.
In step s 130, the organic layer for covering the buffer layer and filling the gap between the microballoon is formed.
As shown in figure 13, the organic layer 3 that covering buffer layer 2 can be formed by inkjet printing or other means, in this process
In, the slow levelling in rough surface that organic layer 3 is formed in microballoon 21, and stopped later admittedly by the microballoon of edge 21
Change, stops dam or from setting blocking dam so as to reduce.
As shown in figure 9, the packaging method of disclosure embodiment may also include that
Step S140, the second inorganic layer for covering the organic layer is formed.
As shown in Figure 4 and Figure 5, can had using chemical vapor deposition, magnetron sputtering, atomic layer deposition or other techniques
Machine layer 3 forms the second inorganic layer 4 on the surface far from buffer layer 2, wherein chemical vapor deposition can be plasma enhancing
Learn vapor deposition, high density plasma enhanced chemical vapor deposition or inductively coupled plasma chemical vapor deposition etc..
The material of second inorganic layer 4 may include SiNX、SiO2、SiC、Al2O3, at least one of ZnS, ZnO, ZSM, ZSM
Including at least ZnO, Al2O3And MgO, certainly, the second inorganic layer 4 is also possible to other materials with barrier water oxygen effect.
In one embodiment, as shown in Figure 1 and Figure 5, buffer layer 2 and organic layer 3 are all exposed the first inorganic layer 1 and are located at side
Part in edge area B, the second inorganic layer 4 can coat organic layer 3 and buffer layer 2, and cover the first inorganic layer 1 and be located at marginal zone B
Part, i.e. the second inorganic layer 4 overlaps in the marginal zone B of the first inorganic layer 1 with the first inorganic layer 1.
