Before assembling, the buffering flexible glue arranged respectively to metal rack or light guide plate in local interference protruding state, after assembling, the protruding parts of buffering flexible glue can under the effect of metal rack or light guide plate, being compressed, add the resistance of relative motion between metal rack and framework, framework and light guide plate, the local interference protrusion value of described buffering flexible glue is preferably 0.15mm, but it is not limited to this, it is possible to according to the protrusion value that the selecting factors such as the concrete structure of product, size, material are optimum.
Further, described framework extends local salient point towards the side of metal rack, metal rack leaves the draw-in groove adapted with the local salient point on framework, framework and the local salient point in metal rack and draw-in groove, it is possible to the relative position between fixed frame and metal rack further.
Further, described buffering flexible glue is rubber or silica gel, but is not limited to this, suitable material can be selected as buffering flexible glue according to the material etc. of concrete technological level, product, in general, hardness less than metal rack, framework, light guide plate the material of hardness be suitable as buffering flexible glue.
Further, described buffering flexible glue is arranged by the mode of injection moulding or assembling in the groove reserved for buffering flexible glue in framework.
Further, described metal rack is brandreth or galvanized aluminium board, rustless steel etc., but is not limited to this.
Further, according to concrete product demand, the exiting surface of light guide plate can be set up blooming in described backlight, such as diffusion barrier, bright enhancement film etc., can also setting up reflector plate between light guide plate and base of frame, framework can arrange brake sack, this is not restricted.
Further, described luminous source is connected to FPC or PCB.
This utility model has the advantages that this backlight arranges buffering flexible glue between metal rack and framework and framework and light guide plate, can eliminate backlight motion environment in time, mutual shock between metal rack and framework and framework and light guide plate, local salient point on framework and the draw-in groove in metal rack also can fix relative position between the two further, eliminate the sound produced between components and parts because of shock.
