Description
Technical field
The utility model relates to field of liquid crystal, particularly the overall plastic back board structure of a kind of Novel LCD.
Background technology
Available liquid crystal display product mainly concentrates on straight-down negative and side entering type two kinds of back light display techniques.The structural framework adopted in side entrance back display technique is panel beating backboard backing structure scheme, and program holistic cost is higher, and panel beating backboard precision in punching production is lower, and product plane degree is difficult to control; Easily deform in the transport of backboard simultaneously, the bad phenomenon such as scraping.For the intensity usually taking in this problem points industry to thicken panel beating thickness or increase backboard entirety for the mode of backboard local raising, these two kinds of modes make backboard integral material cost increase, in the process of producing, add the operation of Sheet Metal Forming Technology, indirectly add backboard cost.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides one and breaks existing panel beating backboard backlight display technique barrier, guaranteeing, under the prerequisite that backlight module Quick uniform dispels the heat, to ensure that the overall plastic back board structure of the Novel LCD of TV product drawing high-grade and low-cost advantage.
The utility model in order to the technical scheme solving its technical matters and adopt is: the overall plastic back board structure of a kind of Novel LCD, comprise LED lamp bar, backboard, reflector plate and light guide plate combination part and glue frame, together with backboard, reflector plate are mounted on successively with light guide plate combination part and glue frame, described backboard is plastic cement backboard, also be provided with panel beating bending platelet and heat sink, described LED lamp bar is pasted at panel beating bending platelet, described panel beating bending platelet is fixed on backboard side, and described heat sink is fixed on the back side of backboard.
As further improvement of the utility model, described LED lamp bar is pasted on panel beating bending platelet by gum.
As further improvement of the utility model, described panel beating bending platelet is fixed by snap on backboard.
As further improvement of the utility model, described heat sink is that aluminum extruded technological forming is made, and heat sink is provided with corrugated structure, and heat sink is assemblied in the back side of backboard by screw.
The beneficial effects of the utility model are: overall plastic back board structure of the present utility model, adopt injection mo(u)lding or plastic uptake processing technology, plastic cement backboard is distributed with corresponding convex closure and muscle bit architecture, in order to guarantee the intensity of backboard itself, to distribute corresponding buckle structure in plastic cement backboard side (LED lamp bar emission side), in order to fixed L ED lamp bar simultaneously.Assemble us for LED heat radiation and LED and devise corresponding panel beating fixed sturcture and heat radiator, in order to ensure that module dispels the heat rapidly and uniformly, ensure that side entrance back technology low cost does not lose the high-grade advantage of picture, the technology barriers of panel beating backboard backlighting scheme are broken, advance the development of side entrance back technology, have obvious cost advantage.
