Determine that whether intact closing of sealed plastic box layer specifically comprise in step d 2: judge whether closing of sealed plastic box layer be intact according to luminous intensity, if the luminous intensity of sealed plastic box layer is dimmed, not sealed plastic box layer closed not intact, otherwise sealed plastic box layer is closed intact; Or
Judge whether closing of sealed plastic box layer be intact according to luminous continuity, if the luminous continuity of sealed plastic box layer changes, closing of sealed plastic box layer is not intact, otherwise sealed plastic box layer is closed intact.Sealed plastic box continuous print is detected whether be coated with complete detection to the sealed plastic box layer of liquid crystal cell surrounding exactly.
Below the present embodiment for add in sealed plastic box mass percent be 1% fluorescent material obtain sealant composition and be described, sealed plastic box wherein in the present embodiment can be the one in HC1850, HC1840, XN-5A, S-WB73-1 and S-UR96-2, because fluorescent material is inorganics, do not react with the organism in sealed plastic box, so the interpolation of fluorescent material is applicable to all sealed plastic boxs, the embodiment of the present invention is only described for HC1850.
There is provided sealant composition and application thereof for above-described embodiment, below enumerate specific examples and be described:
Example 1
With reference to the scheme one in embodiment two, first 60 minutes thawing is carried out to sealed plastic box, then by mass percent be 1% ultraviolet excited fluorescence powder join in the sealed plastic box after thawing, just obtain the sealant composition comprising 1% fluorescent material.Then the sealant composition obtained is carried out to the defoaming treatment of 30 minutes, obtain the sealant composition of not bubbles.
Then the sealant composition obtained is coated on substrate surface surrounding, carry out after instillation liquid crystal array substrate and color membrane substrates position to box, sealant composition is cured, array substrate and color membrane substrates are glued together by sealant composition, form sealed plastic box layer in liquid crystal cell surrounding simultaneously.
Finally, in darkroom, by the fluorescent effect of sealed plastic box layer, bonding effect is detected.Irradiate under above-mentioned liquid crystal panel being placed in invisible light (as UV-light), observe the fluorescent effect of sealed plastic box layer.Due to sealed plastic box layer comprises burst of ultraviolel should light powder, can be excited under the irradiation of UV-light.Just can determine whether closing of sealed plastic box layer be intact according to the fluorescent effect of sealed plastic box layer, avoid trouble that the liquid crystal panel made moves up everywhere in sealed plastic box testing process, save labour turnover, therefore according to the fluorescent effect of sealed plastic box layer, bonding effect is detected, convenient and simple.
Wherein the fluorescent effect of sealed plastic box layer comprises luminous intensity and luminous continuity, can judge whether the thickness that sealed plastic box layer is coated with meets the requirements by detecting luminous intensity, can judge whether sealed plastic box layer is continuous uniform coating by detecting luminous continuity.
Example 2
Be with the difference of example 1, this example with the addition of the dispersion agent that mass percent is 1%, the scheme two of preparation method's reference embodiment two of concrete sealant composition, concrete: by mass percent be 1% ultraviolet excitation fluorescent material and mass percent be 1% dispersant even, the mixture obtained is joined in the sealed plastic box of thawing again, the sealant composition comprising 1% fluorescent material and 1% dispersion agent can be obtained.Other steps are all identical with example 1.
Example 3
This example is that the mass ratio first according to 1:1 in ultraviolet excitation fluorescent material adds dispersion agent equally, but it is different from the adding proportion of scheme two, the i.e. fluorescent material of 5% and the dispersion agent of 5%, still be prepared according to the preparation flow of such scheme two, obtain the sealant composition comprising 5% fluorescent material and 5% dispersion agent.Other steps are all identical with example 2.
The preparation method of the sealant composition that above-mentioned three kinds of examples adopt is exemplary, also can adopt the additive method in embodiment two or additive method of the prior art.
Comparative example
This comparative example is do not add fluorescent material in sealed plastic box after thawing with the difference of example 1, and other steps are all identical with example 1.
Below the fluorescent effect of the sealed plastic box layer that above-mentioned three examples and comparative example obtain and bonding effect are contrasted, as shown in table 1.
The detected result of table 1 sealed plastic box layer
According to table 1 Comparative result, add dispersion agent and can improve fluorescent effect, brightness increases, make detection convenient, but if the decline of bonding effect will be caused during the large percentage added according to dispersion agent in example three and ultraviolet excited fluorescence powder, therefore, preferably, the adding proportion of fluorescent material (the ultraviolet excited fluorescence powder namely in the present embodiment) will control below 5%.
Use the sealant composition prepared of the present embodiment to prepare display panels, after it is to box, the detection method of the bonding effect adopting the present embodiment to provide, by experiment, detects its panel and to split the bonding effect of situation, checking sealed plastic box layer.First the color membrane substrates utilizing sealant composition to bond and array substrate are put and irradiate under ultraviolet light, according to luminous intensity and luminous continuity whether sealed plastic box layer closed again and intactly to judge, if the luminous intensity of sealed plastic box layer is dimmed, closing of sealed plastic box layer is not intact, otherwise sealed plastic box layer is closed intact; If the luminous continuity of sealed plastic box layer changes, closing of sealed plastic box layer is not intact, otherwise sealed plastic box layer is closed intact.This detection method just can detect the bonding effect of sealed plastic box layer by means of only fluorescent effect, and utilize microscope to detect without the need to being transported in special environment by whole liquid crystal panel, avoid in handling process, causing panel broken, detected result can be obtained effectively rapidly.Due to fast easy to detect, the efficiency of detection therefore can also be improved.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
