Embodiment
To make the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings to the utility model
Embodiment is described in further detail.
Which show a kind of structural representation of liquid crystal display die set provided by the utility model.The liquid crystal display die set bag
Backlight module 1 and display panel 3 are included, cushion loop 2 is provided between the backlight module 1 and display panel 3；As shown in figure 4,
Thickness >=0.5mm of the cushion loop, include the elastic spacer 21 and rigid gasket 22 of four L-shaped；The rigid gasket
22 quantity are four, are embedded in middle part of the cushion loop 2 per one side.The elastic spacer 21 use decrement for 40 ~
60% foam is made, and the rigid gasket 22 is made of silica gel, elastic spacer 21 and the splicing composition pad of rigid gasket 22
Ring.The thickness of the rigid gasket is less than the thickness of the elastic spacer and thickness difference is less than 0.3mm, the length of the rigid gasket
Degree is less than 20mm.So, the display panel 3 on cushion loop 2 is just simultaneously by elastic spacer 21 and rigid gasket 22
Support, rigid gasket 22 can effectively support the medium position of its display panel 3, limit the sagging change in middle part of display panel 3
Shape, so as to improve product quality, simultaneously as the thickness of rigid gasket 22 is less than the elastic spacer 21 and thickness difference exists
In 0.3mm, the thickness of elastic spacer 21 after rigid gasket 22 and assembling forced compression is probably equal, can be provided to display panel 3
More smooth support effect, and the length L of rigid gasket is less than 20mm, can preferably ensure not transmit the change of backlight module
Shape, ensure the display effect of display panel.Further, as shown in figure 5, the elastic spacer 21 and rigid gasket 22 use wedge
Shape structure connects.Rigid gasket 22 is connected by wedge structure and elastic spacer 21 avoids in stitching position and occurs running through pad
The rectilinear slot of ring, so as to effectively prevent dust from entering, improve product quality.Further, as shown in fig. 6, the bullet
Property inward flange corresponding edge distance D >=1.0mm from display module viewing area AA of the gasket ring 2 per side, i.e. cushion loop 2
Will be tried one's best the viewing area AA away from display panel, and cushion loop can be allowed correspondingly to be pressed onto in the sealing frame of the display panel,
Reduce the influence to the thick change of box.
Further, strong sticky double faced adhesive tape is passed through as a kind of preferred scheme of the present utility model, the cushion loop 2
4 paste connection with backlight module 1, are pasted and connected by weak sticky double faced adhesive tape 5 and display panel 3.The strong sticky He of double faced adhesive tape 4
The sticky ratio of weak sticky double faced adhesive tape 5 is more than 2:1.Backlight module 1 with cushion loop 2 is bonded by strong sticky double faced adhesive tape 4,
Both fittings are closer, and display panel 3 and cushion loop 2 are bonded by weak sticky double faced adhesive tape 5, and both compare in fitting
Loosen；So, in the deformation that backlight module 1 expands with heat and contract with cold by ambient temperature change, cushion loop 2 can be due to close
Fit on backlight module 1 and corresponding deformation occurs；And because cushion loop 2 and display panel 3 are double by weak viscosity
Face glue 5 is bonded, and fitting more loosens, then display panel 3 will not follow the deformation of gasket ring 2 and deform, but between the two can
It is partially stripped, after being partially stripped, the deformation of cushion loop 2 would not all pass to display panel 3, so as to
Display panel 3 can be protected not to be pulled out of shape easily so that liquid crystal cell occurs deforming and causes liquid crystal in box uneven, and causes
There is the problem of brightness unevenness in display panel；Meanwhile when liquid crystal display die set needs to do over again maintenance, dismounting separation back light unit
1 and display panel 3 during, because cushion loop 2 and back light unit 1 are pasted relatively closer, and paste ratio with display panel 1
It compared with loosening, therefore can quickly to separate cushion loop 2 and display panel 3 during dismounting, both be not in because being bonded
In closely causing that cushion loop 2 deforms and occur the problem of being scrapped together with the backlight module being bonded with cushion loop 2,
Be not in that display panel 1 deforms the problem of damaged because being bonded tension by cushion loop 2 in dismounting.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute
The technical scheme of acquisition, it all should fall within the scope of protection of the utility model.
