Technical field
The invention belongs to back light model setting technology fields, specifically, are related to backboard, the backlight of a kind of no glue frame backlight module
Mould group and display module.
Background technique
Liquid crystal display device has been widely used in various electronic products as the display unit of electronic equipment, and is carried on the back
Optical mode group is then an important component in liquid crystal display device.Backlight module is divided into side according to the difference of light source entry position
Enter formula backlight module and two kinds of down straight aphototropism mode set.Side entrance back module includes backboard, connect cooperation with back plate edges
Glue frame, light guide plate, optical film material group and side entering type light source led lamp bead etc..
Wherein middle glue frame mainly plays each backlight assembly of support and panel, makes an entirety, Neng Gouding
The position of position and backlight module in the product of position screen in the module, in addition also plays side envelope light and reflected light.Cause
It is typically complex for its structure, and thin, it requires that its molding raw material mobility and strength and toughness will be got well.In addition reflective
Property also has certain requirement, there is very high reflection coefficient if the polycarbonate containing 4%TiO2.The structure of glue frame is designed to backlight
Efficiency have a great impact.Because glue frame is the carrier of various optical diaphragms, to have in glue frame for placing various light
Learn slot of the diaphragm without generating pressure to it.When structure design, the reasonability of structure is not only considered, it is also contemplated that
Glue frame mold manufacturability and produceability and mouldability.
To sum up two o'clock is not difficult to find out glue frame Supported film material, positions the effect of penel and have closing light and reflected light
The effect of line, but it is this have modeling backlight module design also along with assembling, operation is difficult a series of problems, such as, such as: 1, glue
Width of frame is relatively narrow, and intensity is weaker, and it is bad to be easy to appear fracture, deformation etc. in assembling, it is not easy to the problems such as positioning；2, workability
It is bad, and there are excessive membrane material and glue frame fixation adhesive tape, the big problems of the cumbersome difficulty of operation.
Summary of the invention
In order to solve the above technical problems, the purpose of the present invention is to provide a kind of backboards of no glue frame backlight module, backlight
Mould group and display module, no glue frame design, by directly improving design to backboard, support and positioning instead of glue frame are made
With, therefore adhesive frame structure can be saved, it is therefore prevented that a series of problems generated when having glue frame.
What the object of the invention was realized in:
One, a kind of backboard of no glue frame backlight module, key are: and including bottom plate and positioned at the bottom edge hanging down
The bending plate of straight bottom plate setting, the bending plate is to 180 ° of formation pleateds of bending on the inside of the backboard, the inside portion of the bending plate
Bending again is divided to go out an erecting bed parallel with the bottom plate.Using the above structure, backlight module uses original bending process
Bending and molding is carried out, erecting bed intensity is high, is unlikely to deform, support performance is good.
Two, a kind of no glue frame backlight module, key are: including reflector plate, light guide plate, membrane material group, panel and such as power
Benefit require 1 described in backboard, the reflector plate, light guide plate, membrane material group and panel be successively set on from the bottom up in the backboard,
The edge of the membrane material group is fixed by erecting bed support, and the panel is directly mounted in the membrane material group, and described
Shading rubber belt is set between panel and the edge of membrane material group, the upper and lower surface of the shading rubber belt respectively with the panel and film
Material group bonding, the shading rubber belt edge are Nian Jie with the inboard portion of bending plate.
Using the above structure, the edge of membrane material group directly passes through erecting bed and is supported fixation, and stability of strutting system is high, simultaneously
It can play a supporting role to the panel in membrane material group, indeformable, positioning is more convenient, reduces glue frame and glue frame fixation adhesive tape
Installation procedure, process is simpler, operation convenience improve.
Preferably, the upper surface of above-mentioned erecting bed is flushed with the upper surface of light guide plate, the intermediate body portions of the membrane material group
Divide and passes through light guide plate support.
Three, a kind of display module, it is characterised in that: including the described in any item backlight modules of such as claim 2~3.
The utility model has the advantages that
The present invention a kind of backboard, backlight module and the display module of no glue frame backlight module, pass through setting again to backboard
Meter reduces glue frame and glue frame fixation adhesive tape, avoids in glue frame so that backlight module of the present invention compares existing backlight module
The problems such as falling into guarantees product quality；Reduce glue frame and glue frame fixation adhesive tape, decreases process when installation, and install
More scheme, operation convenience are improved.
