Description
Technical field
The present invention relates to display technology field, more particularly to a kind of backlight module and its display device.
Background technology
Rimless and ultra-narrow frame have become the development trend of liquid crystal display device.Liquid crystal display device it is main
Part be display panel and backlight module, backlight module mainly include center, light guide plate and backboard, and Rimlessization and
The realization of ultra-narrow frame depends primarily on the structure of center in backlight module, and light guide plate and backboard and center fixation side
Case.
In the prior art, the middle frame structure of Rimless and ultra-narrow frame, and light guide plate and backboard and center fixation side
Case mainly has two kinds, and the first scheme is as shown in figure 1, display device includes display panel 104 and backlight module, backlight module bag
Include center 102, light guide plate 103 and backboard 101.This programme is using pressure light guide plate backing structure, i.e., directly in the side wall of center 102
The stepped projection for pressing solid light guide plate 103 and backboard 101 respectively is processed on surface, it is stepped raised including the first projection 1021
With the second projection 1022, directly, backboard 101 is arranged on the lower section of the first projection 1021, and it is raised that light guide plate 103 is arranged on second
1022 lower section is simultaneously relative with the side of the first projection 1021, and the upper surface of the second projection 1022 of the solid light guide plate 103 of pressure is used for
Place and fixed display panel 104, realize the assembling of Frame-free liquid crystal display device.
In order to be described in detail this programme, exemplified by 65 cun of PMMA of first choice or resinae light guide plate, and display panel 104 includes
Viewing area and non-display area, the black surround BM sizes of the non-display area of existing display panel resource display panel can be as small as
3mm ranks.As shown in Fig. 2 in the program, light guide plate is apart from display panel viewing area edge AA areas（Covered comprising the second projection
The size of lid pressure light guide plate）Size A >=2.2mm, the distance between the raised side of light guide plate distance first is swollen for light guide plate
Swollen gap B >=2.2mm, the first projection length of stationary backplate adds center thickness size for C >=5mm, therefore display panel is shown
The back gauge that arrives of region to center lateral surface is W1=A+B+C >=9.4mm, and display panel black surround BM size is only BM=3mm,
Therefore definitely frame is W1=W1-BM=9.4-3 >=6.4mm, and the larger display panel BM that has been even more than of the absolute frame is worth two
Times size, causes appearance poor, is disagreed with the theory of Rimless or ultra-narrow frame, it is impossible to truly realize " nothing
The effect of frame ".
Moreover, this scheme is arranged on the lower section of the projection 1022 of center 102 second due to light guide plate 103, can only during assembling
Using outside backboard 101 to the assembling that backlight module is realized by the way of the reverse locking screw in the direction of display panel 104, this group
Dress method reduces efficiency of assembling, is unfavorable for production.
Second scheme is as shown in figure 3, the backlight module in program liquid crystal display device includes center 202, light guide plate
203 and backboard 201, display panel 204 is further comprises in liquid crystal display device.The program uses and does not press light conducting plate structure,
One projection 2021 is only set in the side wall inner surfaces of center 202, and for the fixation to backboard 201, light guide plate 203 is located at backboard
201 top, and the side and the side of projection 2021 of light guide plate 203 are oppositely arranged, display panel 204 is located at light guide plate
203 top, and the lower surface of display panel 204 is fixedly connected with the upper surface of projection 2021.
For detailed description this programme, equally select exemplified by 65 cun of PMMA or resinae light guide plate, and display panel
204 include viewing area and non-display area, the black surround BM sizes of the non-display area of existing display panel resource display panel
It can be as small as 3mm ranks.
As shown in Fig. 2 size A >=0.1mm of the light guide plate 203 apart from the viewing area edge AA areas of display panel 204, guide-lighting
Plate 203 is the expansion clearance B of light guide plate 203 >=2.2mm apart from the distance between side of projection 2021, stationary backplate 201 it is convex
Playing 2021 length adds the thickness size of center 202 to be C >=5mm, therefore the viewing area of display panel 204 is to the lateral surface of center 202
It is W1=A+B+C >=6.2mm to back gauge, display panel black surround BM size is only BM=3mm, therefore definitely hem width W1=W1-BM
>=3.2mm, compared with display panel black surround BM=3mm, or it is larger, and in this scheme on display panel 204 and center 202
Between raised 2021 upper surface of setting be adhesively fixed apart from d=BM-（B-|A|）=3-（2.2-1）=0.8mm, but at present
0.8mm bonding space can not meet the fixation of display panel 204.
Light guide plate 203 only has the limitation of display panel 204 on the vertically displayed direction of panel 204 in this scheme, not
The limitation of corresponding construction on to center 202, and the fixed form of display panel 204 is convex to be fixed on using tape-stripping scheme
On the upper surface for playing 2021 so that light guide plate 203, which easily oppresses display panel 204, causes display panel bonded structure to damage, very
To the problem of causing disengaging center 202 of display panel 204.
Stationary backplate, light guide plate and display panel are met because the center in Rimless liquid crystal module needs to set simultaneously
Structure, in the case where only changing middle frame structure, if setting two structures of stationary backplate and light guide plate to lead on center
Cause the absolute W1 that broadens larger, be even more than twice of BM black surrounds, but if only setting the structure of stationary backplate on center,
Also it is to show another caused defect even if the W1 that definitely broadens will effectively be reduced, but still be more than black surround BM value
Show that panel pastes fixed distance only 0.8mm, it is impossible to meet the fixation of display panel, and light guide plate does not obtain center
It is fixed, cause light guide plate to extrude display panel, easily cause the problem of display panel comes off.
Therefore, solve prior art problem it is crucial that in Rimless liquid crystal module, realizing that light guide plate is solid well
Calmly and do not influence on the basis of other assemblies fixation, realize that absolute frame W1 is worth reduction.
The content of the invention
The present invention provides a kind of backlight module and display device there is provided a kind of new center and back board structure, realizes and leads
Tabula rasa is fixed well, reduces the size of absolute hem width W1 values, and center corresponding construction has enough spaces to realize and display
The fixation of panel.
First aspect present invention provides a kind of backlight module, including back board module, center, light guide plate, wherein, the backboard
