In conjunction with shown in Fig. 1-Fig. 3, the utility model embodiment provides a kind of narrow frame display device, including backlight module
100 and the display module 200 of the top of backlight module 100 is set, is passed through between the backlight module 100 and display module 200
The two-sided sticking rectangular-ambulatory-plane shading glue 300 of tool is adhesively fixed.Usual display device has intermediate viewing area and around viewing area
Peripheral rim area, as the technology of narrow frame develops, it is necessary to increase viewing area area, rim area area reduces, inevitable
Will lead to bonding area between backlight module 100 and display module 200 to reduce, backlight module 100 and display module 200 it
Between be easy to fall off.
Display module 200 described in the utility model includes bottom sheet polaroid 210, the liquid for stacking gradually laying from the bottom up
Brilliant display base plate 220 and upper piece polaroid 230, the lower end surface of the bottom sheet polaroid 210 are Nian Jie with the upper surface of shading glue 300
It is fixed so that display module 200 is adhesively fixed with backlight module 100 in turn.
220 side of liquid crystal display substrate, which is extended to, forms substrate branch 240 beyond 210 1 distance of bottom sheet polaroid,
The upper surface of the substrate branch 240 is additionally provided with driving IC250, the driving IC250 should be apart from 210 1 safety of bottom sheet polaroid
Bonding distance at distance A, the driving IC250 corresponding with shading glue 300 of bottom sheet polaroid 210 is bonding distance B, in order to anti-
Only being bonded the too small of distance B causes backlight module 100 to be easy to fall off with display module 200, and the utility model proposes the bottom sheet
Polaroid 210 be equipped with driving IC250 one end extend outwardly a distance C formed bottom sheet polaroid branch 211, the bottom sheet is inclined
Mating plate branch 211 avoids driving IC250 setting and bottom sheet polaroid branch 211 should be apart from driving IC250 not less than safe distance
A, can use bottom sheet polaroid branch 211 in this way and shading glue 300 is pasted to increase backlight module 100 and display module
200 bonding area effectively prevent backlight module 100 to fall off with display module 200.
As shown in figure 4, the substrate branch 240 of the liquid crystal display substrate 220 as a further improvement of the utility model,
A hanging space is formed between shading glue 300, is provided with buffer substrate tablet 400, and 400 court of the buffer substrate tablet in the hanging space
Do not have viscosity to the surface of the liquid crystal display substrate 220, it will not be with 220 adhesion of liquid crystal display substrate.The bottom sheet polarisation
Piece 210 is the orthogonal polaroid of light transmission shaft with upper piece polaroid 230.Liquid crystal display substrate 220 includes being cascading
Lower layer's glass 221 and upper layer glass 222 on the bottom sheet polaroid 210.
In the utility model, surface (i.e. lower layer glass 221 of the buffer substrate tablet 400 towards the liquid crystal display substrate 220
Surface) apart from the 220 certain distance D of liquid crystal display substrate so as to be formed between buffer substrate tablet 400 and liquid crystal display substrate 220
Have for avoiding the first gap being interference fitted between the two, cannot overcome lower sheet glass is hanging to lack if distance D is too big
It falls into, but if distance D is too small, in tolerance or assembling, it is possible to will appear interference fit, lower layer's glass 221 is pushed up
Play even fragmentation.
On the other hand, the buffer substrate tablet 400 is towards the side wall of the bottom sheet polaroid 210 apart from the bottom sheet polaroid
210 certain distance E between buffer substrate tablet 400 and bottom sheet polaroid 210 so as to be formed with for avoiding being interference fitted between the two
Second gap will lead to lower layer's glass of top if avoiding buffer substrate tablet 400 and bottom sheet polaroid 210 contacts with each other overhead
221 are arched upward, and are influenced liquid crystal display effect and equally liquid crystal display substrate 220 can be made frangible, therefore buffer substrate tablet 400 and bottom sheet are inclined
There are certain intervals between mating plate 210, but if gap is excessive, the liquid crystal display substrate 220 above gap does not have herein
Support, fragile structure.
The buffer substrate tablet 400 is made of PET or to paste the one side glue facing towards the backlight module 100, buffer substrate tablet 400
It is pasted on the shading glue 300 of rectangular-ambulatory-plane side by side with bottom sheet polaroid 210, the buffer substrate tablet 400 is towards the one of lower layer's glass 221
Face cannot have viscosity, so if buffer substrate tablet 400, if it is one side glue, one side glue tool is sticking to be pasted facing towards described
Backlight module 100.
Finally, it should be noted that above embodiments be only to illustrate the technical solution of the embodiment of the present invention rather than to its into
Row limitation, although the embodiment of the present invention is described in detail referring to preferred embodiment, those skilled in the art
It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are modified or wait
The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
