Description
Technical field
Multimedia equipment field is the utility model is related to, more particularly to a kind of periphery is bonded hermetically sealed liquid crystal display die set.
Background technology
Liquid crystal display mode stack screen laminating type on the market includes frame patch and full fitting at present.So-called frame patch is also known as mouth
Word glue laminating, i.e., it will simply be fixed and pasted with backlight module after the Four built in boundaries of screen protection glass and liquid crystal panel with double faced adhesive tape
Close.Wherein, the structure of backlight module is followed successively by from top to bottom：The anti-dazzling screen of frame shape, upper bright enhancement film, lower bright enhancement film, diffusion
Piece, light guide plate, the side of light guide plate are provided with light source, and backlight module is installed in a glue frame, set and reflect in glue frame lower surface
Film, chase backboard is installed after reflectance coating.The advantages of frame sticking structure, is that its technique is simple and cost is cheap, but because screen is protected
There is the air gap, these the air gaps can produce reflective diplopia and image loss, cause figure for shield glass and liquid crystal panel
As overall unintelligible, be also easy to cause screen hair mist, it is mouldy, enter ash while be also less prone to radiate.In addition, in manufacture large scale liquid crystal
During display, also there is a significant deficiency in frame patch product：Liquid crystal display area is bigger, and liquid crystal panel thick only 1mm is more difficult in frame
Inside only stood erectly with bottom support, easily arch sticks up forward or backward, and 84 cun of liquid crystal panel even can protrude 6~10mm.Protecting
When touch-control extrudes on glass and the collision of these salient points can produce newton aperture, and it is bright that screen body can be then produced when being contacted backward with light guide plate
Spend unbalanced problem.
The processing technology being bonded entirely is after screen protection glass is bonded integrally completely with liquid crystal panel using optical cement
Fixed again with backlight module.The arch that the liquid crystal display die set of full attaching process manufacture can solve liquid crystal panel sticks up problem, and
And because screen protection glass is bonded with liquid crystal panel gapless, then also solve screen hair mist, it is mouldy, enter ash while be also less prone to
The problem of radiating.But it easily produces bubble during being bonded, and yields is low, if liquid crystal display damages during use, also can not
Disassemble to repair.
Liquid crystal display die set uses iron plate or plastic plate as backboard at present simultaneously, and onboard adds the side of heat emission hole
Method solves heat dissipation problem.Add heat emission hole easily to enter ash, moisture fog is entered in machine, iron plate plastic plate heat conduction and heat radiation performance
Difference, the high part of temperature in module is caused easily to deteriorate aging.In view of the defects of frame patch is with full jointing product at present, market in urgent need one
Kind high yield rate and easy to process and maintenance the hermetically sealed lcd products of large scale.
The content of the invention
It is complete close that the purpose of this utility model is to provide a kind of easy to process and maintenance and thickness ultrathin periphery fitting
Seal liquid crystal display die set.
Realizing the technical scheme of the utility model purpose is, a kind of periphery is bonded hermetically sealed liquid crystal display die set, and it includes
Liquid crystal panel protective layer, liquid crystal panel and the backlight module being sequentially bonded, the backlight module include brightness enhancement film, diffusion barrier,
Light guide plate, light source, reflective membrane and seal back plate；Liquid crystal panel protective layer, liquid crystal panel, light guide plate and the seal back plate are adopted
With optics glue, the optical cement is pasted onto the surrounding and liquid of the liquid crystal surface plate face of relative fitting with liquid crystal panel protective layer
Four of each element facing surface outside the central, clear map region formed between crystal panel, light guide plate and seal back plate
Week；The brightness enhancement film, diffusion barrier are clipped in the central, clear map region between liquid crystal panel and light guide plate respectively, the light source
Light guide plate both sides are fixedly installed in, the reflective membrane is clipped in the central, clear map region of light guide plate and seal back plate, described
The back side periphery of liquid crystal panel protective layer is printed with black coating.
Further, the liquid crystal panel protective layer is screen protection glass or is made up of screen protection glass with touch control film
Touch-screen group.
Further, the FPC lead-out wires fitting of the liquid crystal panel is fixed on the optical cement on periphery.
Further, it is marked with argon gas between the liquid crystal panel protective layer and liquid crystal panel.Argon gas have it is colourless, tasteless,
The characteristics of nontoxic, its molecular weight weigh 38% compared with air, and thermal conductivity ratio air is small to be not easy heating hair mist, and due to argon gas blanketing
Encountering in the presence of two sheet glass when can prevent from pressing screen integrally causes to produce newton aperture.
Further, the black coating is black ink layer.
Further, the seal back plate is aluminium sheet or glass plate, can directly radiate and add the Strong sealings of finished product
Energy.
Further, the back side of the screen protection glass is dull surface.Newton ring of light when can prevent from firmly pressing screen
Generation and diffusion.
The periphery that the utility model is realized is bonded the glue frame and iron that hermetically sealed liquid crystal display die set has broken former backlight module
Mount structure, by liquid crystal panel protective layer, liquid crystal panel, light guide plate, seal back plate directly against integrator, the fitting of its periphery and in
Between the structure that is not bonded of transparent map region, both reduced the air gap between former frame patch product multilayer optical assembly, do not allowed
Easily hair mist it is mouldy enter ash, improve screen body brightness and penetrating degree again, can improve reflective diplopia by reducing Air gap thickness
And image loss, improve image entirety definition；And glued construction more consolidation is extruded by multilayer sandwich, due to eliminating
Outer framework, backlight module group rubber frame and chase are supported, is also significantly thinned module thickness, liquid crystal panel is pind down by four hoop tensions,
Be not susceptible to deformation, then prevented liquid crystal panel and forward or backward encircle to stick up, ensure screen definition and light refraction it is equal
Even property.The back side periphery of the liquid crystal panel protective layer is pasted with the invisible area that black coating frame forms liquid crystal display die set,
Realization is blocked to bonding portion, and its is compact-sized, easy to process, and its each fitting position can be cut using fret saw
Cut decomposition to repair, improve the convenience of maintenance.
