Embodiment
The assembling fixed form of at present common LCD is preceding frame 600, backboard 700 and framework 100 are fixed together by manner, the bottom surface of backboard 700 is in order to make reflector plate 300 and framework 100, support the weight of whole LCD, because preceding frame 600, backboard 700 and framework 100 and reflector plate 300 overlaying relation in vertical direction, make the thickness of LCD comprise the thickness of preceding frame 600 and backboard 700, the thickness of the LCD of the main flow electronic product below 7 inches is generally in 2 millimeter, and the thickness of preceding frame 600 and backboard 700 is 0.2 millimeter, is about about 1/5 of whole LCD integral thickness; On outer profile size, because backboard 700 and framework 100 overlaying relation in the horizontal direction make outer profile size increase the thickness of two-layer backboard 700, thereby increased the size of whole LCD; Because preceding frame 600 and backboard 700 are metal material, thereby have increased the weight of LCD, usually, the weight of preceding frame 600 and backboard 700 accounts for about 1/6 of whole LCD.
Based on above-mentioned analysis, the utility model provides a kind of LCD, in order under the prerequisite of the support strength that guarantees the constant and framework in viewing area, reaches the purpose that makes LCD more frivolous.
Below in conjunction with Figure of description preferred embodiment of the present utility model is described, be to be understood that, preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model, and under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.
The LCD that the utility model provides, by framework 100, light guide plate 200, reflector plate 300, optical film material 400 and the fixing composition of liquid crystal panel 500 assemblings, framework 100 is made up of inside casing 101 and glue frame 102, wherein:
Compare with existing LCD, owing to saved preceding frame 600 and backboard 700, both reduced the waste of material, dwindled the size of LCD again, reduced the thickness of LCD, and alleviated the weight of LCD, simultaneously owing to need not preceding frame 600, backboard 700 are fixed together by the snap-in structure that is provided with framework 100, thereby simplified the number of assembling steps of LCD.
In concrete the enforcement, inside casing 101 can select for use the material that can satisfy the support strength of framework 100 on vertical direction and horizontal direction to make, and is preferred, can be metal material or the intensity composite suitable with metal material.
Preferably, inside casing 101 and glue frame 102 adopt the one injection molding way to be injection-moulded in together.The principle of the Cross section Design of inside casing 101 for can guarantee whole framework in the horizontal direction with vertical direction on support strength, in order to support whole display module.Especially, the cross section of inside casing 101 can be designed as " L " shape or half back-shaped aciculiform.As shown in Figure 2, be injected into the front elevational view of the framework 100 of one for what the utility model embodiment provided by inside casing 101 and glue frame 102; As shown in Figure 3, the three-dimensional side view of the framework 100 that provides for the utility model embodiment; As shown in Figure 4, the skeleton view of the framework 100 that provides for the utility model embodiment.
Embodiment one
As shown in Figure 5, be first kind of possible cross section structure synoptic diagram of LCD that this enforcement new embodiment provides, among the utility model embodiment, inside casing 101 is injection-moulded in the outside of glue frame 102, and the Cross section Design of inside casing 101 is " L " shape.Preferably, the outside height of inside casing 101 is concordant with the outside height of described glue frame 102, can reduce the outer profile size of LCD like this; Perhaps, the bottom surface of the bottom surface of inside casing 101 and glue frame 102 is positioned at same plane, like this, can reduce the integral thickness of LCD.Certainly, when specifically implementing the utility model, when inside casing 101 is injection-moulded in glue frame 102 outside, can both make that the outside height of inside casing 101 was concordant with the outside height of described glue frame 102, make the bottom surface of inside casing 101 and the bottom surface of glue frame 102 be positioned at same plane again.
