Abstract
The utility model discloses a backlight framework, a backlight module and a liquid crystal display, and aims to solve the problem of a ripple phenomenon on the liquid crystal display caused by the conventional metal rim or the conventional backboard. The backlight framework comprises a framework main body and a fixing piece which is made of a flexible material and arranged on the outer side of the framework main body, wherein one part of the fixing piece is connected to the framework main body and the other part of the fixing piece is connected to an element arranged in the framework main body. The fixing piece is a heat conduction rubber band for connecting the framework main body and the element in an adhesive manner. By the backlight framework, the ripple phenomenon or a non-uniform color phenomenon caused by hard-hard contact between the metal rim and a panel is eliminated; furthermore, the problem that fragments influence a backlight is solved, the thickness and the weight of the whole module are reduced, the production period is shortened, and the cost is saved. The liquid crystal display which uses the backlight framework has a better display effect.

The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of backlight framework that frame causes ripple or irregular colour phenomenon of eliminating.
For achieving the above object; The utility model is realized through following measure: the backlight framework comprises the fixture that chassis body and the flexible material that is arranged on the said chassis body outside are processed; A said fixture part is connected on the said chassis body, and another part is connected on the display element that is arranged in the chassis body.
Particularly, said fixture is for pasting the heat conduction adhesive tape that connects said chassis body and said display element.
A kind of backlight source module comprises backlight framework and the display element that is arranged in the said backlight framework, and said backlight framework is above-mentioned backlight framework.
A kind of LCD comprises above-mentioned backlight source module.
The utility model backlight framework replaces virgin metal frame and backboard with the fixture of flexible material; Eliminated hard between metal edge frame and panel-contact waviness phenomena or the irregular colour phenomenon of bringing firmly; Also solved simultaneously the problem of debris backlight performance effectively; Reduced the thickness and the weight of module whole, shortened the production cycle, practice thrift cost.Heat Conduction Materials such as use heat conduction adhesive tape prepare fixture can make backlight integral heat sink better effects if.
The utility model backlight frame structure is reasonable, and cost is low, and result of use is good.
Description of drawings
Fig. 1 is for using the existing backlight anchor structure sketch map of metal edge frame.
Fig. 2 is for using the existing backlight anchor structure sketch map of metal backing.
Fig. 3 is the utility model preferred embodiment structural representation.
The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model is done detailed description.
Existing backlight framework all is to be made up of chassis body and the metalwork that is fixed on the chassis body outside, through metalwork framework and the display element that is provided with is wherein fixed.As shown in Figure 1, panel 22 is installed in the chassis body 21 with the backlight assembly that is arranged under it jointly, and metal edge frame 23 fixes in framework 21 outsides, and chassis body 21 and panel 22 assemblies such as grade that are arranged on are wherein fixedly become one.As shown in Figure 2, panel 22 is installed in the framework 21 with the backlight assembly that is arranged under it jointly, and metal backing 24 is fixed on the framework 21, and metal backing 24 is mainly played a supporting role.
In order thoroughly to solve problems such as waviness phenomena, irregular colour phenomenon and debris backlight performance, the fixture that the utility model backlight framework uses flexible material to process substitutes existing metalwork.This flexible material is stretching, extension to a certain degree to take place under external force and at the external force revertible material in back that disappears, the extension degree of this material is confirmed according to concrete operating position.The fixture of flexible material fixedly becomes one chassis body and the assemblies such as panel that are arranged on wherein, and waviness phenomena or irregular colour phenomenon have been eliminated in the soft-hard contact between the fixture of flexible material and the panel.Fit tightly between the fixture of flexible material and the panel, eliminated chip, foreign matter gets into the gap of backlight source module.The fixture of flexible material can use methods such as stickup, binding when connecting panel and chassis body respectively.
Preferred embodiment: as shown in Figure 3, the utility model backlight framework comprises chassis body 2 and the fixture 1 that is arranged on chassis body 2 outsides.The display elements that are arranged in the chassis body 2 are followed successively by polaroid 6 from top to bottom, color film 4, and glass substrate 3, is gone up prism film 8, time prism film 9, diffusion barrier 10, LGP 12 and reflectance coating 11 at following polaroid 5, diaphragm 7.Above-mentioned display element relies on chassis body 2 supports and location, uses fixture 1 to be fixed into chassis body 2 and the display element that is arranged on wherein as a whole better.
The shape of fixture 1 is decided according to concrete operating position, and fixed frame main body 2 gets final product with the display element that is provided with wherein effectively.Fixture 1 can be a monoblock type, also can be split type.Its material is a flexible material, preferably uses the good flexible material of heat conductivility, so that chassis body 2 and the display element quick heat radiating that sets within it.
The good heat conduction adhesive tape of fixture 1 preferred heat conductivility.As shown in Figure 3, display element is installed in the chassis body 2 successively, post with the heat conduction adhesive tape is as shown in the figure.The heat conduction adhesive tape is a flexible material, stick between heat conduction adhesive tape and the panel on the panel surface for soft-contact firmly, eliminated waviness phenomena or irregular colour phenomenon.
The heat conduction adhesive tape sticks on respectively on chassis body 2 and the panel surface, securely chassis body 2 and display element wherein is fixed into one.And the heat conductivility of heat conduction adhesive tape is good, is beneficial to the rapid heat radiation of backlight source module.The heat conduction adhesive tape sticks on the panel surface, has eliminated the gap, has avoided chip, foreign matter to get into backlight source module from here and influences the backlight performance.
The utility model backlight framework replaces virgin metal frame and backboard with the heat conduction adhesive tape; Eliminated metalwork and contacted waviness phenomena or the irregular colour phenomenon of bringing firmly-firmly with panel; While has also solved chip entering backlight source module effectively and has influenced the problem of backlight performance; Reduced whole thickness and the weight of backlight source module, shortened the production cycle, practice thrift cost.The heat conduction adhesive tape is pasted with the U-shaped mode, can make chassis body and the display element that is arranged on wherein fix more firmly.And Heat Conduction Materials such as use heat conduction adhesive tape can make backlight source module integral heat sink better effects if.
The utility model backlight frame structure is reasonable, and cost is low, and result of use is good, in being particularly suitable for, undersized backlight assembly.
A kind of backlight source module comprises backlight framework and the display element that is arranged in the said backlight framework, and said backlight framework is above-mentioned backlight framework.
A kind of LCD comprises above-mentioned backlight source module.Eliminated waviness phenomena or irregular colour phenomenon, avoided chip, foreign matter gets into backlight source module, thereby improved the display effect of display.
