Technical field
The relevant a kind of display assembly of the present invention, particularly the framed structure of relevant a kind of liquid crystal display assembly is improved, to strengthen the stationarity between liquid crystal panel and framework.
Background technology
In traditional liquid crystal display assembly assembling operation, a Thin Film Transistor-LCD (Thin Film Transistor-Liquid Crystal Display for example; TFT-LCD); generally can between liquid crystal panel and metal outer frame, add last layer plastic cement frame; as fixing, protection usefulness, one be fixed in the plastic cement frame on the sidewall around the liquid crystal panel by this, reduce the destruction of liquid crystal panel because of producing with the metal outer frame direct collision.The plastic cement frame also can be used to auxiliary optical thin film layer and the backlight assembly that links panel and its below, makes whole LCD inside obtain good fixed support, and strengthens the assembleability of LCD.Be an oblique view of traditional plastic cement mount structure shown in Fig. 1 a, wherein the plastic cement frame is by around barricade 10 covering liquid crystal panel 14 sidewalls, and winding displacement 16 and signal line 18 are then connected by panel below and left side respectively.And Fig. 1 b is the xsect of A-A ' position among Fig. 1 a, by Fig. 1 b as can be seen liquid crystal panel 14 after packing into, come together support by barricade 10 and bearing base 12.
But traditional plastic cement frame still has its shortcoming to exist on reality is used.At first, general liquid crystal panel its up and down series of strata cover by a glass substrate, so when the liquid crystal panel pressurized, this glass substrate then breaks easily.And because the sliver tolerance of glass substrate (± 0.2mm) greater than the making tolerance of plastic cement frame (± 0.1mm); therefore when design plastic cement frame; general many plastic cement frame inside dimension slightly can the increasing; liquid crystal panel can be packed in the plastic cement frame smoothly; and can not be corrupted to glass substrate; but therefore regular meeting's generation liquid crystal panel can't closely be fixed in the plastic cement frame; when serious even can produce the situation of rocking; at this moment just must fill up this gap, not only waste man-hour and consuming cost with other filling materials.And if bigger than normal when the sliver tolerance of glass substrate, and the processing procedure tolerance of plastic cement frame then causes the assembling difficulty when less than normal, when serious even cause glass substrate stressed improper and break.
In addition, compared to glass material, plastic cement is bigger for being subjected to the deflection that temperature effect produces.So when the plastic cement frame is subjected to temperature variation and during contraction or expansion, also can cause liquid crystal panel to be easy to generate to break or the situation of rocking takes place.
Summary of the invention
In above-mentioned background of invention, the many shortcoming of prior art on the framed structure of display assembly, one of purpose of the present invention is to provide a kind of improvement of framed structure of display assembly, can make when design plastic cement frame, inside dimension does not need painstakingly to strengthen, and avoids liquid crystal panel to shake.
Another object of the present invention is to provide a kind of framed structure improved display assembly, can avoid framework because the expansion that temperature variation produced is shunk, and causes the liquid crystal panel pressurized to break or produce and rocks.
Another purpose of the present invention provides a kind of improved display assembly of framed structure, can avoid because the variation of the ejaculation tolerance during frame manufacture causes size bigger than normal or too small, and liquid crystal panel is loosening or break when causing assembling.
A further object of the present invention provides a kind of rework rate, production cost and raising liquid crystal panel goods yield display assembly of reducing.
Display assembly of the present invention is in order to carrying, fixing and protection liquid crystal panel.This display assembly has the framed structure of a rectangular box, is used to contract a display panel, has a barricade around it.Characteristics of the present invention are that at least one corner portions of this barricade has an opening, make the inside of frame size not need painstakingly to strengthen, and avoid framework because expansion or contraction that temperature variation produced, cause the liquid crystal panel pressurized to break or rock.Secondly, madial wall has an inclined-plane around this barricade, and the bottom on this inclined-plane and the level interval at top are not more than 0.5mm, can avoid because the tolerance the when glass substrate of liquid crystal panel and frame manufacture makes a variation, cause size bigger than normal or too small, cause when assembling panel loosening or break.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.

Embodiment
Some embodiments of the present invention can be described in detail as follows.Yet except this was described in detail, the present invention can also be widely implements at other embodiment.That is scope of the present invention is not subjected to the restriction of the embodiment that proposed, and should be as the criterion with the claim that the present invention proposes.Moreover in this manual, the different piece of each element is not drawn according to size.Some yardstick is compared with other scale dependents and is exaggerated or simplify, so that clearer description and understanding of the present invention to be provided.
In liquid crystal display assembly, can add around the liquid crystal panel side that generally a framework is as protecting fixing using.And link the optical thin film layer and the backlight assembly of liquid crystal panel below by this framework and metal outer frame.By aforesaid Fig. 1 b as can be known, the part of being responsible for bearing liquid crystal display panel 14 is the right angle part that barricade 10 and bearing base 12 are constituted, and by barricade 10 that liquid crystal panel 14 sides are attached all around.Generally when design framework, in order to make the liquid crystal panel framework of packing into smoothly, framework inside is many can reserve bigger size.But because framework mostly is one by polycarbonate (Polycarbonate, PC), just general plastic cement, or mix the rectangular box that glass fibre constitutes by polycarbonate, and the ejaculation tolerance of plastic cement makes many liquid crystal panels behind the framework of packing into greater than the sliver tolerance of the glass substrate of liquid crystal panel, can cause the space to produce, avoid liquid crystal panel to shake so the engineering staff must insert filling material in addition in the space, this action not only increases cost and also expends man-hour.
The present invention at first proposes a kind of framed structure improved procedure of display assembly, make framework when design, not need painstakingly to amplify inside dimension, therefore liquid crystal panel has been not easy the shaking phenomenon generation after packing into, even the too driving fit of size between the two of framework and liquid crystal panel can not cause glass substrate on the liquid crystal panel to be subjected to excessive compression yet and breaks.Please refer to Fig. 2, be one of framed structure improved procedure of the present invention.Because framework is a rectangular box, so in the intensity of corner location part necessarily greater than other long leg branches, if therefore partly form opening in the barricade of corner location at framework, then can be so that barricade can produce bigger distortion, when the liquid crystal panel of being packed into pushes, bigger holding capacity can be arranged, and the strength back-pressure can not returned liquid crystal panel itself, destroy and produce.Therefore, also do not need again inside dimension to be strengthened yet, just do not have the problem that liquid crystal panel becomes flexible easily yet when framework during in design.As shown in Figure 2, three corner portions located of barricade 20 are removed, form three groups of openings 22, the barricade that only stays a jiao does not remove, by on the figure as can be seen, removed the opening 22 of barricade, only remaining bearing base.
Yet only remove three corners of barricade, and the purpose that keeps one of them corner is: at first, liquid crystal panel of the present invention is for example by colored filter (Color Filter) and thin film transistor (TFT) (Thin Film Transistor; TFT) the overlapping liquid crystal panel of forming, its overlap mode and ratio how as shown in Figure 3, below be thin film transistor (TFT) 30, the top is the less colored filter of area 32, then mostly is glass substrate in the levels of thin film transistor (TFT) 30 structures.In general, thin film transistor (TFT) 30 and colored filter 32 are that to be with upper left corner that benchmark aligns overlapping, therefore should be the part of intensity the best in the liquid crystal panel in the upper left side, and it is comparatively fragile comparatively speaking by other three limits that the corner constituted, thereby destruction also occurs near these three limits that the corner constituted particularly easy cracked glass substrate mostly.So when the design framework structure, select the barricade in these three corners is formed opening.In addition, another purpose is, stays next complete corner to can be used as reference point when liquid crystal panel is packed framework into, makes the assembling operation can be more smooth.
The mode that above-mentioned three corners with the framework barricade form opening only is one embodiment of the invention.If four corners of framework barricade are partly all formed opening, do not stay the upper left side reference point, make four corners all form open area, the same effect that face glass destroys that prevents also still can be arranged.In addition, when assembling the panel of reduced size, because with respect to large-sized panel, the deflection on its each limit is also less, so two positions or only form opening at a corner arbitrarily on also can be only at framework in when design also can have identical effect.From the above, framed structure of the present invention can be looked actual needs, at different liquid crystal panel sizes, does the variation design of different modes.
Above-mentioned corner portions located with the framework top retaining wall forms the design of opening, can also be used to solving the disappearance of another prior art.Because plastic cement material is with respect to glass material, the deflection that produces for temperature variation institute is also bigger, particularly the part of close each limit central authorities.Suppose unexpected decline to take place when temperature, the size of each limit middle body of barricade will produce contraction, and the barricade corner portions located is because structure is not yielding, the liquid crystal panel that is loaded on framework inside this moment will be because of stressed and cause its glass substrate to destroy, particularly on three corners that structure approaches and the limit that connected thereof.Therefore, three corner portions located corresponding to the liquid crystal panel structure thin location on barricade form openings, even framework produces contraction or expansion because of temperature variation, also can too not be expressed to liquid crystal panel, and cause breaking glass panel.
Next, another improved design of the present invention is described.As shown in Figure 4, form an inclined-plane 44 on our barricade 40 madial walls around the framework, promptly the angle of barricade 40 and 42 of bearing bases is by original vertical, and formation is slightly larger than 90 and spends.Make liquid crystal panel after packing into, produce a space between its sidewall and the barricade 40.This inclined-plane 44 is generally with allowance below nominal size on it, and promptly the level interval at bottom and top is not more than 0.5mm and designs, but the big I on inclined-plane 44 is made suitable change according to actual needs.The purpose of this inclined design promptly is, even when the size of liquid crystal panel is slightly larger than the framework inside dimension, liquid crystal panel is packed in the framework smoothly, and can not make that glass substrate breaks.Even if when framework is bigger than normal, liquid crystal panel also is difficult for shaking.The framed structure of liquid crystal panel of the present invention; can simultaneously aforementioned two kinds of architecture advances modes be established on the framework; make this framework after improving can overcome variation of making ability and influence that external temperature caused, reach function fixing, the protection liquid crystal panel really.
Comprehensive above-mentioned explanation, maximum characteristics of the present invention promptly be, three corner portions located of framework top retaining wall are respectively had an opening, makes the corner form open state, and have an inclined-plane in the barricade inboard.Compared to traditional prior art, the framework of this architecture advances, the problem of can more effective solution liquid crystal panel rocking, and can avoid liquid crystal panel to destroy.Furthermore, can reduce and meaningless remedy making step, reduce man-hour and production cost, promote liquid crystal panel serviceable life and quality.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present invention in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
