Abstract

The utility model relates to the technical field of liquid crystal display, in particular to a removable L/B (length breadth ratio) mechanism, which comprises a back plate and a substrate provided with LED lamp groups. A clamp pin for limiting the substrate in movement along the X direction is arranged on the substrate, and a clamp groove for fixing the clamp pin is correspondingly arranged on the back plate. The removable L/B mechanism is simple in structure, and is convenient to remove as the substrate and the back plate are fixedly connected by the simple design of fasteners and clamp grooves. Moreover, double-sided adhesive tapes and screws are no longer used, assembly working hours are saved, and the manufacturing cost of a liquid crystal panel is further reduced.

Description

Can substitute the L/B mechanism arrangement

Technical field

The utility model relates to technical field of liquid crystal display, specifically, relates to a kind of L/B of substituting mechanism arrangement.

Background technology

Along with development of science and technology, lcd technology is more and more ripe, and TV is also from using traditional kinescope to develop into the use LCDs.Because LCDs is passive luminous display screen, display panels itself is not luminous, so LCDs needs module backlight that light source is provided.

Module backlight can be divided into CCFL module backlight, LED-backlit module etc., and the LED-backlit module is easy to carry out reasons such as subregion control because its color reducibility is good, has become the main flow backlight of LCDs.And the LED-backlit module is according to the unusual side light type LED back light module and the direct-light type LED backlight module of being divided into of led light source position, the side light type LED back light module is installed in the side, the led light source of direct-light type LED backlight module is installed in the bottom, include backboard and the substrate that LED lamp group is installed, there is following shortcoming in it: 1, the side of backboard is provided with salient point and is used for directions X location, it can only limit LED lamp group to the moving of X+ direction one side, and can not limit moving to X-direction one side; 2, use screw to lock, and use double faced adhesive tape to attach, its cost increases man-hour; 3, with location, backboard bottom surface Z direction, the loss of work appears easily, the waste time cost.

The utility model content

The utility model has overcome shortcoming of the prior art, and a kind of L/B of substituting mechanism arrangement is provided, and has effectively limited backboard moving on directions X.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of L/B mechanism arrangement of substituting comprises backboard and the substrate that is provided with LED lamp group, and described substrate is provided with the card base that restricting substrate moves on directions X, the corresponding fixedly draw-in groove of card base that is provided with on the described backboard.

Further, described card base comprises the side card base, and described side card base is located at aforesaid substrate one end.

Further, described card base comprises the base card base of being located at the aforesaid substrate bottom.

Further, described base card base is " L " shape card base.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model is simple in structure, and is by the design of simple buckle, draw-in groove that substrate and backboard is affixed, conveniently substitutes, and do not re-use double faced adhesive tape and screw, saved the man-hour of assembling, and then reduced the manufacturing cost of liquid crystal panel.

2, side card base and base card base design by suitable dimensions, can effectively limit L/B the moving of Z-direction, and so also just can not attach too high or hang down the light leak that causes module light-emitting area backlight excessively because of L/B.

Embodiment

Shown in Fig. 1 to 4, the L/B mechanism arrangement of substituting described in the utility model, comprise substrate 1 and backboard 2, this substrate 1 is provided with LED lamp group 3, one end of substrate 1 is provided with side card base 4, side card base 4 restricting substrates 1 move on directions X, and backboard 2 one end correspondences are provided with the side draw-in groove 5 of fixation side checkpost pin 1.

Substrate 1 bottom is provided with base card base 6, and base card base 6 is " L " shape card base, and backboard 2 correspondences are provided with base draw-in groove 7, its big I is inserted in it base card base 6, laterally move again, can substrate 1 is fixing, can while restricting substrate 1 moving on x, y and z direction.

Fig. 5 to Fig. 8 is the synoptic diagram after substrate and the backboard assembling, and substrate 1 is fixed on the side plate of backboard 2 by side card base 4 and base card base 6, does not re-use double faced adhesive tape and screw, and fixation.

The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
