Description
Technical field
The present invention relates to a kind of LCD MODULE, particularly comprise the LCD MODULE of the silicagel pad of new construction.
Background technology
LCD MODULE receives the influence of external force easily in the process of producing, using, it is bad to cause picture to show.When LCD MODULE received external pressure, display panels was easy to generate buckling phenomenon, and it is bad to cause picture to show; When LCD MODULE received exterior vibration, display panels moved in that LCD MODULE is inner, with other parts generation friction generates foreign matter on every side, directly contacted with outside framework sometimes and produced the ripples face that paints and show bad.In order to address the above problem, in the present LCD MODULE, between display panels and mold framework, placing the cross section is the silicagel pad of rectangle.
Fig. 1 is the schematic partial cross-sectional view of LCD MODULE of the prior art.As shown in Figure 1; LCD MODULE comprises: outside framework 1, mold framework 2, display panels 3 and silicagel pad 4; Wherein, display panels 3 is placed on the mold framework 2, and silicagel pad 4 is between display panels 3 and mold framework 2; Outside framework is positioned at the top of display panels 3, is used for fixing mold framework 2 and display panels 3.
But because the elasticity of silicagel pad 4 is relatively poor; Can not effectively prevent phenomenon crooked when display panels 3 receives external pressure; Can not prevent moving of display panels when LCD MODULE is given a shock; Sometimes display panels 3 directly contacts with outside framework 1, also causes the generation of ripples line (RIPPLE).The undulatory bad picture of water that so-called ripples line occurs when being meant the box thickness ununiformity of display panels 3.And display panels 3 also can cause damage because of bumping with outside framework 1.When display panels 3 separates with silicagel pad 4, produce the gap, at this moment foreign matter also can get into module internal, and then influence shows image quality.
Summary of the invention
The objective of the invention is defective to prior art; A kind of LCD MODULE is provided,, solves display panels and move through the silicagel pad of new construction is set between display panels and mold framework; The problems such as generation of ripples line can also prevent that foreign matter from getting into the viewing area.
To achieve these goals, the present invention provides a kind of LCD MODULE, comprising: outside framework, mold framework, display panels and silicagel pad,
Said display panels is placed on the said mold framework,
Said silicagel pad between said display panels and said mold framework,
Said outside framework is positioned at the top of said display panels, is used for fixing said mold framework and said display panels,
It is characterized in that: said silicagel pad offers recess, and contacts with display panels and to form a cavity, so that said display panels compresses said cavity, said display panels is attached on the said silicagel pad through vacuum action.
The present invention compared with prior art has following advantage:
1, utilizes vacuum adsorption principle immobile liquid LCD panel, immobile liquid LCD panel effectively.
2, between display panels and outside framework, form suitable gap, can prevent the generation of ripples line.
3, can prevent effectively that foreign matter from getting into module internal.

Embodiment
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Fig. 2 is the not stressed schematic partial cross-sectional view that is in the LCD MODULE of normal morphology of silicagel pad of the present invention.As shown in Figure 2; LCD MODULE of the present invention comprises: outside framework 1, mold framework 2, display panels 3 and silicagel pad 4; Said display panels 3 is placed on the said mold framework 2; Said silicagel pad 4 is between said display panels 3 and said mold framework 2, and said outside framework 1 is positioned at the top of said display panels 3, is used for fixing said mold framework 2 and said display panels 3; Said silicagel pad 4 offers recess 411, and contacts with display panels 3 and to form a cavity.
Fig. 3 is the sectional view of silicagel pad of the present invention.As shown in Figure 3, silica gel is lined with two parts formation up and down, and top is vacuum formation portion 41, and recess 411 is located in the vacuum formation portion; The bottom is support portion 42, is fixed on the mold framework 2, is used to support vacuum formation portion 41.Wherein, the cross section of recess 411 is for trapezoidal.
Fig. 4 is in the schematic partial cross-sectional view of the LCD MODULE of stress morphology for silicagel pad of the present invention.As shown in Figure 4; Under the action of gravity of display panels 3; The cavity that forms between silicagel pad 4 upper recess 411 and the display panels 3 will be compressed; Display panels 3 almost contacts with the bottom of recess 411, and like this, the air of cavity the inside will be discharged to the silicagel pad 4 outside states that form similar vacuum.At this moment, the air pressure of recess 411 and display panels 3 formed cavity insides is less than the air pressure of silicagel pad 4 outsides, and under the effect that silicagel pad 4 atmosphere outside are pressed, display panels 3 just is attached to together with silicagel pad 4 tightly.Like this, silicagel pad 4 is effective immobile liquid LCD panel just, prevents moving of display panels; And eliminated the gap between display panels and the silicagel pad, it is bad to prevent that foreign matter from getting into the picture that module internal causes.
When display panels and silicagel pad being attached to effectively also can when module is assembled, on mold framework, paste together silicagel pad to place display panels, push display panels.
After module backlight had been assembled, silicagel pad was crushed, and had just formed certain clearance between outside framework and the display panels.Like this, LCD MODULE display panels in the process of transporting also is not easy and the outside framework collision, thereby has avoided the generation of ripples lines and the breakage of display panels.
Fig. 5 is the synoptic diagram of del for the cross section of the recess of silicagel pad of the present invention.Fig. 6 is semicircular synoptic diagram for the cross section of the recess of silicagel pad of the present invention.Fig. 7 is polygonal synoptic diagram for the cross section of the recess of silicagel pad of the present invention.Like Fig. 5, Fig. 6 and shown in Figure 7, the cross section of the recess of silicagel pad of the present invention can be del, semicircle or polygon, but is not limited to these figures.As long as on the silicagel pad with the contacted surface of display panels on a face, being shaped as Any shape and can both playing same effect of recess.Recess adopts the ideal design as the case may be of which type of shape effects to get final product.
The present invention not only can prevent that compared with prior art foreign matter from getting into module internal; And utilize vacuum adsorption principle immobile liquid crystal panel effectively to fix display panels; And make display panels and outside framework form certain clearance, thereby can prevent the generation of ripples line.
It should be noted last that; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and the scope of technical scheme of the present invention.
