In order to keep the following explanation of the embodiment of the present disclosure to understand and concise, known function and known portion is omitted in the disclosure
The detailed description of part.
The embodiment of the present invention provides a kind of sealant, for encapsulating display panel, is mixed with illuminator in sealant, shines
Body shines when being irradiated by default light, and does not shine with the illuminator of moisture when being irradiated by default light.
Sealant provided in an embodiment of the present invention is mixed with illuminator, and the illuminator is sent out when being irradiated by default light
Light, and do not shine with the illuminator of moisture when being irradiated by the default light, and then aobvious encapsulating the sealant
When showing panel, since illuminator will do it luminous when not by moisture attacks, and the illuminator after by moisture attacks is by default
Without shining when light irradiates, then for there is no the position of leak vapour, illuminator will do it in the position it is luminous, and for
There is the position that leak vapour occurs, illuminator can be determined according to non-luminous position by water in the position without shining
The position that vapour corrodes is realized when to display panel storage or the test of high temperature and humidity reliability, the hydrometeor of discovery leakage in real time, very
Easily leak vapour position detection is come out, simplifies the undesirable process of analysis of environment reliability.
In the specific implementation, illuminator can be fluorescent conjugated polymer, and fluorescent conjugated polymer is by ultraviolet light
Shi Faguang, and do not shine when by ultraviolet light with the fluorescent conjugated polymer of moisture.In the embodiment of the present invention, shine
When body is fluorescent conjugated polymer, which stablizes, and thermal stability is good.And if there is moisture attacks, steam
It will lead to conjugated polymer to assemble, the self aggregation of fluorescent conjugated polymer causes exciton transition to be obstructed, and leads to fluorescent material
Fluorescent quenching occurs.It therefore, can be by ultraviolet lamp, it is easy to judge leakage point, can find leakage vapour gas phenomenon in real time.

It is uniformly distributed, can be better achieved and be detected to whether the sealant of each position of display panel occurs leak vapour, be kept away
Exempt to be distributed uneven, can not to detected when causing sealant that leak vapour occurs defect due to illuminator.
In the specific implementation, sealant provided in an embodiment of the present invention is glass cement.In the specific implementation, due to specific
It when encapsulation, relies primarily on glass cement (Frit glue) and is packaged, but when this kind of Frit glue generation leak vapour, and be difficult to pass through naked eyes
With microscope it has been observed that therefore, when being mixed into illuminator in this kind of Frit glue, the effect of leak vapour location point occurs for detection
It is more obvious.
In the specific implementation, illuminator is fat-soluble fluorescent conjugated polymer.In the embodiment of the present invention, illuminator is liposoluble
Property fluorescent conjugated polymer, due to fat-soluble fluorescent conjugated polymer (such as polyhenylene ethynylene, polyphenylene vinylene, poly- thiophene
Pheno etc.) with the solvent of Frit glue there is good dissolubility, it may be implemented to be dispersed in Frit glue.
Below with sealant be Frit glue, Frit glue incorporation illuminator be fat-soluble fluorescent conjugated polymer for,
Testing principle when in conjunction with Fig. 1-Fig. 3 to progress leak vapour detection provided in an embodiment of the present invention is further described, wherein
Fig. 1-Fig. 3 is the partial top structural schematic diagram in the region that sealant is arranged in display panel.
It is shown in Figure 1, when the Frit glue 1 in display panel sealant area is not incorporated into fluorescent conjugated polymer, using purple
When outer lamp 2 irradiates, the Frit glue 1 of display panel does not shine in the region S of irradiation.
Shown in Figure 2, the Frit glue 1 in display panel sealant area mixes fluorescent conjugated polymer and Frit glue 1 not
When being invaded by steam, when being irradiated using ultraviolet lamp 2, display panel Frit glue 1 shines in the region S of irradiation.
Referring to Fig. 3, the Frit glue 1 in display panel sealant area mixes fluorescent conjugated polymer and 1 part of Frit glue position
It sets when being invaded by steam, when being irradiated using ultraviolet lamp 2, portion of the Frit glue 1 of display panel in the region S of irradiation is not sent out
Light (the region A in 3 in such as figure), and remaining position shines, then can determine that non-luminous position A is to be invaded by steam
Region.
Based on the same inventive concept, the embodiment of the present invention also provides a kind of display panel, shown in Figure 4, display panel
Encapsulation cover plate 4 including substrate 3 and on substrate 3, display panel further include such as envelope frame provided in an embodiment of the present invention
Glue, sealant are, for example, Frit glue 1, wherein Frit glue 1 is located at the non-display area of display panel, and substrate 3 and encapsulation cover plate 4 are logical
Cross sealant (i.e. Frit glue 1) sealing.Specifically, the sealant being distributed in display panel is to surround the ring-type of viewing area, with
Substrate and encapsulation cover plate are subjected to the sealing-in up and down at frame in the non-display area of non-display area.
In the specific implementation, display panel is organic light emitting display panel.Specifically, can be active matrix organic light-emitting
Diode (Active-matrix organic light emitting diode, AMOLED).
The embodiment of the present invention also provides a kind of display device, including such as display panel provided in an embodiment of the present invention.
Based on the same inventive concept, the embodiment of the present invention also provides a kind of detect such as the display panel of the embodiment of the present invention
Detection method, shown in Figure 5, detection method includes：
Step S101, a display panel is provided；
To detect display panel leak vapour occurs for step S10,2, the sealant irradiation using default light to display panel
Location point.
Specifically, sealant can be the Frit glue for being mixed into polyhenylene ethynylene, polyphenylene vinylene or polythiophene, then close
It is irradiated in step S102, using sealant of the default light to display panel, to detect the location point that leak vapour occurs for display panel,
It can specifically include：It is irradiated using sealant of the ultraviolet light to display panel, to detect the position that leak vapour occurs for display panel
Point.
The embodiment of the present invention has the beneficial effect that：Sealant provided in an embodiment of the present invention is mixed with illuminator, and is somebody's turn to do
Illuminator shines when being irradiated by default light, and does not send out with the illuminator of moisture when being irradiated by the default light
Light, and then when the sealant is encapsulated display panel, due to illuminator will do it when not by moisture attacks it is luminous, and by water
Vapour corrode after illuminator by default light irradiate when without shine, then for there is no the position of leak vapour, illuminators
It will do it in the position luminous, and for there is the position that leak vapour occurs, illuminator, and then can be in the position without shining
It is determined according to non-luminous position by the position of moisture attacks, realizes and tested to display panel storage or high temperature and humidity reliability
When, the hydrometeor of discovery leakage in real time, it is easy to which ground comes out leak vapour position detection, simplifies the undesirable parsing of environment reliability
Process.
