Embodiment
The lower problem of reliability that the embodiment that the utility model provides exists at prior art liquid crystal display module, by the position corresponding to liquid crystal panel is provided with groove on the sidewall top of the backlight framework of liquid crystal display module, and between described sidewall and liquid crystal panel, encapsulant being set, the part of wherein said encapsulant is housed in described groove.Gap by between the side that adopts above structure elimination liquid crystal panel and backlight framework reduces the possibility that impurity enters described liquid crystal display module inside, thereby improves the reliability of described liquid crystal display module.
Please consult Fig. 3 and Fig. 4 simultaneously, it is floor map and the diagrammatic cross-section of a kind of embodiment of the utility model liquid crystal display module.Described liquid crystal display module 200 comprises the liquid crystal panel 210 and the backlight 220 of superimposed setting.
Described backlight 220 comprises framework 221, reflector plate 222, light guide plate 223, optical diaphragm group 224.Described framework 221 is a rectangular frame, it comprise a base plate 225 and along described base plate 225 edges to vertically extending four sidewalls 226 of same direction.Described base plate 225 and sidewall 226 cooperatively interact and surround a receiving space.
Each sidewall 226 comprises a bottom 227 and a top 228, and wherein said bottom is the part near described base plate 225, and described top is the part away from described base plate 225.And the thickness of described bottom is slightly smaller than the thickness of described bottom, and thus, described sidewall forms groove 229 on its top.
The height of described sidewall 226 approximates the gross thickness of described reflector plate 222, light guide plate 223, optical diaphragm group 224 and liquid crystal panel 210 greatly.And the thickness of the bottom 227 of described sidewall 226 is slightly less than the thickness sum of described reflector plate 222, light guide plate 223 and optical diaphragm group 224.
Described reflector plate 222, light guide plate 223 and optical diaphragm group 224 are arranged on the receiving space inside of described framework 221 in regular turn.Wherein, described optical diaphragm group 224 can comprise polaroid and prismatic lens etc.Further, in specific embodiment, described backlight 220 also comprises light source (figure does not show), and as light emitting diode or cold cathode fluorescent tube, described light source can be close to described light guide plate 223 and be provided with, as is arranged on its side or bottom surface.
Described liquid crystal panel 210 be arranged on equally described framework 221 receiving space in, and be positioned at described optical diaphragm group 224 surfaces.Because described liquid crystal panel 210 and described backlight 220 satisfy above-mentioned thickness/height relation, therefore, the part zone, side of described liquid crystal panel 210 is relative with the bottom of described sidewall 226, and another part zone is relative with the top of described sidewall 226, and promptly the side of described liquid crystal panel is relative with groove 229 in the described framework 221.
Further, also be provided with encapsulant 230 between the sidewall 226 of described liquid crystal panel 210 and described framework 221, described encapsulant 230 can be fluid sealant etc.Particularly, in described liquid crystal display module 200 assembling process, can in described groove 229, add encapsulant 230, such as gluing, described encapsulant 230 parts can extend to described liquid crystal panel 210 sides and described liquid crystal panel 210 fits, and major part can be contained in described groove 229 inside.By described encapsulant 230, just there is not the space between the sidewall 226 of described liquid crystal panel 210 and described framework 221 substantially.Therefore, by described encapsulant 230, just can effectively stop impurity particle (as dust etc.) or liquid enter as described in liquid crystal display module 200 inside.
In addition, for holding described encapsulant better, improve the seal degree of described liquid crystal display module 200, described liquid crystal panel 210 also can further be provided with the depressed area in its side top and described groove 229 relative positions.By this structure, encapsulant 230 is after adding described liquid crystal display module 200 to, and the depressed area of described liquid crystal panel 210 can be extended and accommodate to a part.
In sum, the liquid crystal display module 200 that the embodiment of the invention provides passes through to form grooves 229 at the sidewall 226 of the framework 221 of backlight 220, and in described groove 229, add encapsulant 230, realize the sealing between described backlight 220 and the described liquid crystal panel 210.Described encapsulant 230 can effectively intercept impurity and enter described liquid crystal display module 200 inside, this can improve the display performance of described liquid crystal display module 200 on the one hand, and the impurity that also can avoid on the other hand entering described liquid crystal display module 200 inside damages optical elements such as described reflector plate 222 or light guide plate 223.Therefore, the reliability of described liquid crystal display module 200 is higher.
