Specific embodiment
In order to which the technical solution of the utility model is explained further, below in conjunction with attached in the utility model embodiment
Figure, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only
It is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff every other embodiment obtained without making creative work belongs to the utility model guarantor
The range of shield.
Embodiment one
Liquid crystal display die set includes liquid crystal display panel and cover board 10.Liquid crystal display panel includes stacking gradually from bottom to top
Down polaroid 21, array substrate 31, liquid crystal layer 50, color membrane substrates 30 and the upper polaroid 20 of setting.Upper polarisation 20 is rectangular sheet
Shape has two groups of four lateral margins being oppositely arranged and an incidence surface and a light-emitting surface.Color membrane substrates 30 and cover board 10 divide
The incident side and light emission side of upper polaroid 20 are not set, and the incident side side of upper polaroid 20 is provided with adhesion layer, makes
Polaroid 20 is fixed on the upper surface of color membrane substrates 30.
Fig. 2 is a kind of diagrammatic cross-section for display module that the utility model embodiment one provides.Fig. 3 is the utility model
The assembling bottom view of a kind of upper polaroid, squeegee and cover board that embodiment one provides.As shown in Figures 2 and 3, cover board 10 is arranged
In the top of the upper polaroid 20, cover board 10 can be protection glass and/or touch panel.Four sides of 10 bottom surface of cover board are set
It is equipped with blocking arm 11, is interconnected between adjacent blocking arm 11 and collectively forms an accommodating space, upper polaroid 20 with 10 bottom surface of cover board
Accommodating is in the accommodating space.To guarantee the good translucency of display module, eliminate in existing frame sticking structure by air layer 41
Caused by Newton's ring and display effect difference problem, 20 light emission side of upper polaroid abuts against with 10 bottom surface of cover board.To guarantee cover board
10 with the good fixed structure of color membrane substrates 30, squeegee 40, squeegee 40 are provided between cover board 10 and color membrane substrates 30
For being fixedly connected and making cover board 10 and about 30 color membrane substrates to fit closely with color membrane substrates 30 cover board 10.
As shown in figure 3, squeegee 40 is continuously set between cover board 10 and color membrane substrates 20, and it is located at cover board blocking arm 11
Outside, the height that squeegee 40 is coated with are equal to the height that cover board blocking arm 11 protrudes 10 bottom surface of cover board.Certainly, in other embodiments
In, in the case where guarantee display module good sealing effect, the height that squeegee 40 is arranged can also be greater than cover board blocking arm
The height of 11 protrusion 10 bottom surfaces of cover board, the utility model do not limit this.
Illustratively, squeegee 40 is attached at the outer surface of blocking arm 11, and is coated with the hollow to form a closure, and presss from both sides
The width that the width that layer glue 40 is arranged protrudes cover board blocking arm 11 with color membrane substrates 30 is consistent, and makes the design of display module structure more
Step up to gather.Since the part that color membrane substrates 30 protrude cover board retaining wall 11 is the non-display area of display panel, in this region
Sandwich establishment glue 40 does not influence the normal display function of display module.Meanwhile four lateral margins of upper polaroid 20 and cover board blocking arm
11 inner surfaces abut against, so that upper polaroid 20 and the combination effect of cover board 10 are more stable.
To increase the color membrane substrates 30 and the cover board by way of continuous sandwich establishment glue 40 in said structure
Bond area between 10, had not only increased adhesion reliability and display module stability, but with 30 phase of cover board 10 and color membrane substrates
A confined space is collectively formed in interworking conjunction, has prevented the pollution of external environment steam and dust, while squeegee 40 is good solid
Determining effect fits closely upper polaroid 20 and about 10 cover board, eliminates the air layer 41 that conventional frame is sticked in meter, improves
The display effect of display module.
Embodiment two
Fig. 4 is the assembling bottom view of a kind of upper polaroid of the offer of the utility model embodiment two, squeegee and cover board.Such as
Shown in Fig. 4, squeegee 40 is arranged at intervals between cover board 10 and color membrane substrates 30, and is attached at 10 two opposed blocking arms of cover board
On 11 lateral surfaces.Above-mentioned package assembly can guarantee cover board 10 with color membrane substrates 30 and positioned at upper polaroid 20 between the two
While good fixed effect, the usage amount of squeegee 40 is saved, cost is reduced.Certainly, reaching the utility model beneficial to effect
In the case where fruit, set-up mode of the squeegee 40 between cover board 10 and color membrane substrates 30 can also there are many, the utility model
It does not limit this.
Embodiment three
Fig. 5 is a kind of diagrammatic cross-section for display module that the utility model embodiment three provides.As shown in figure 5, this reality
The structure for applying the display module that example three provides and the display module that embodiment one provides is essentially identical, the difference is that squeegee
40 setting positions and 40 material of squeegee is further limited, the present embodiment three is no longer to the knot being the same as example 1
Structure repeats.
As shown in figure 5, squeegee 40 and upper polaroid 20 are set to cover board blocking arm 11 and 10 bottom surface shape of cover board jointly
At accommodating space in.Illustratively, the hollow groove that squeegee 40 is filled in cover board blocking arm 11 and upper polaroid 20 is formed
It is interior.
Preferably, the squeegee 40 can be shadowless glue or low-temperature hot melt adhesive, to prevent from scalding during colloid solidification
Upper polaroid 20.Shadowless glue is a kind of by cured adhesive after ultraviolet light, and curing rate is fastly and at room temperature
Solidification, it is small using more convenient and pollution；The low-temperature hot melt adhesive is a kind of adhesive of plasticity, and curing exotherm is few, and public hazards are low,
Adhesion strength is strong, the existing certain flexibility of glue-line, hardness, and has certain toughness.Certainly, the squeegee 40 can also be other classes
The glue of type, such as moisture-curable or the glue of spontaneous curing, the utility model do not limit this.
Preferably, squeegee 40 is black shading glue, the occurrence of to prevent leak-stopping light.Certainly, the utility model is to this
Without limitation, display module prevents there are many modes of 20 light leakage of upper polaroid the color of squeegee 40, such as to cover board blocking arm 11
Carrying out shading treatment also can reach the effect for preventing light leakage.
Meanwhile to guarantee that display module can keep good display effect under ambient irradiation, in display module
Upper polaroid 20 select AG (anti-hyun light) polaroid, i.e., by the upper polaroid 20 close to the TAC (triacetate fiber of cover board 10
Element) layer progress concave-convex surface processing, light is evenly dispersed, to reach antiglare effect.
The utility model also provides a kind of display device, including any display module in backlight and above-described embodiment.
By a kind of display module provided by the embodiment of the utility model, the light for issuing the display device from backlight
It can be projected with gapless into cover board 10 after upper polaroid 20, improve display effect, while be thinned the thickness of display device
Degree, and cover board blocking arm 11 and squeegee 40 play the role of dual resisteance and sealing to upper polaroid 20, make the display device
Have both the effect of good dustproof and waterproof vapour.
The full content of the utility model above, in the present specification, the terms "include", "comprise" or its it is any its
He is intended to non-exclusive inclusion by variant, in addition to comprising those of listed element, but also may include being not explicitly listed
Other element.
