Description
[technical field]
The present invention relates to a kind of organic electroluminescence display device and method of manufacturing same (Organic LightEmitting Display, OLED) manufacture method.
[background technology]
Along with the develop rapidly of science and technology, people are also more and more higher to the requirement of display unit, make display unit develop to lighter, thinner, more power saving direction, thereby produced organic electroluminescence display device and method of manufacturing same.Because of organic electroluminescence display device and method of manufacturing same is that self-luminous shows, compared to liquid crystal indicator, need not the bigger module backlight of energy consumption, so therefore its lighter, thinner, more power saving has obtained extensive use.
See also Fig. 1, structural representation for a kind of organic electroluminescence display device and method of manufacturing same in the prior art, this organic electroluminescence display device and method of manufacturing same 100 comprises first substrate 110 and second substrate 120 that is oppositely arranged, be arranged on relative two surfaces sealant 130 all around of these two substrates 110,120, paste hygroscopic agent 140 and the organic electroluminescence cell 150 that is arranged in this second substrate 120 in this first substrate 110.These two substrates 110,120 and sealant 130 form a confined space, and this hygroscopic agent 140 and organic electroluminescence cell 150 are arranged in this confined space.This hygroscopic agent 140 and organic electroluminescence cell 150 are separately positioned on relative two surfaces of these two substrates 110,120, and this hygroscopic agent 140 also is oppositely arranged with this organic electroluminescence cell 150.
This hygroscopic agent 140 is generally alkaline earth metal oxide (MO), as calcium oxide (CaO), magnesium oxide (MgO) etc., is arranged in the substrate with powdery or film mode, is used to absorb the water vapour in the confined space, keeps the confined space inner drying, and its reaction equation is:
MO+H
2O→M(OH)
2
Since alkaline earth metal oxide activity a little less than, wettability power is relatively poor, so the alkaline earth metal oxide is gradually by the stronger alkaline earth metal hydride (MH of wettability power
2) replace.
See also Fig. 2, be the manufacturing flow chart of organic electroluminescence display device and method of manufacturing same shown in Figure 1.At first, provide one first substrate 110 and it is carried out ultraviolet light clean.
Then, in nitrogen environment hygroscopic agent 140 is pasted in this first substrate 110, this hygroscopic agent 140 contains alkaline earth metal hydride (MH2), as calcium hydride (CaH2), magnesium hydride (MgH2) etc.
At last, provide second substrate 120 with organic electro luminescent unit 150, in vacuum environment, first substrate 110 and second substrate 120 are fitted and sealing, make organic electroluminescence display device and method of manufacturing same 100.
Yet the hygroscopic agent 140 that this process for manufacturing organic electroluminescence display apparatus adopts contains alkaline earth metal hydride, and this hygroscopic agent 140 be finished product, generally needs through just pasting after packing, transportation and the storage.In addition, this alkaline earth metal hydride activity is higher, and its time in packing, transportation and storage process is longer, and chemical reaction very easily takes place, and makes these hygroscopic agent 140 wettability powers lose, and then makes these organic electroluminescence display device and method of manufacturing same 100 yields descend.
