Abstract
The utility model discloses a novel liquid crystal display backlight module without a middle frame, which consists of a hardware front frame, glass, a composite material light enhancing plate, a lower diffusing plate, a light guiding plate, heat conduction adhesive, an LED light strip, a hardware back plate A, a hardware back plate B, a hardware back plate C, a hardware back plate D, a reflecting plate, an insulation plate and buffering materials EVA (ethylene-vinyl acetate). The composite material light enhancing plate, the lower diffusing plate, the light guiding plate, the head conduction adhesive, the LED light strip and the reflecting plate are located in the hardware back plates, the heat conduction adhesive is adhered under the LED light strip, the LED light strip is located at the lower end of the hardware back plate, the reflecting plate is located on the inner wall of the hardware back plates, the light guiding plate is arranged on the reflecting plate, the lower diffusing plate is disposed above the light guiding plate, the composite material light enhancing plate is arranged above the lower diffusing plate, the glass is arranged above the composite material light enhancing plate, and the glass is embedded in the hardware front frame. The novel liquid crystal display backlight module adopts the hardware back plates to replace the middle frame, can strengthen the strength of a product, avoids generating cracks or constantly enlarging the cracks due to stress concentration, and more effectively protects assembly simplicity and stability of a display and increases market competitiveness when personnel are not required to assemble the middle frame.
Description
Technical field
The utility model relates to a kind of LCD backlight module.
Background technology
Along with LCD product is constantly popularized, though product is at hundred grade working tables, thousand inter-stages carry out, but employee group immediately, foreign matter packed in the product, when particularly packing center into, because of center material relation, the atrament that has granule oozes out, and all there is this problem in present most center, and unique method is to light under the lamp bar, with the sticking black removal material of viscose glue, the employee long-time in the face of this light-emitting area, for a long time it, eyes just be can't see very little atrament, the upright finished product of group is to finished product detection, FQC detects atrament, and it is judged to be foreign matter, and the personnel that do over again pull down center from backboard, the break-in of knife and center, make it drop a lot of black material materials again on diaphragm, the composite wood brightening piece is easier to adsorb this small material again with following diffusion sheet material, allows the employee increase man-hour when the cleaning atrament, produce a collection of 10000PCS finished product, account for 8% as above-mentioned foreign matter is bad, it is that the employee overcomes production that present this phenomenon can only be selected, and influences output and progress.Nowadays LCD TV, push market with LCD after, be subjected to masses and like, product also can constantly improve raising in that price is corresponding with performance, optimizes the product internal structure, the control product cost allows liquid crystal module have competitive advantage more.
The utility model content
The purpose of this utility model is, a kind of novel no center LCD backlight module is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of novel no center LCD backlight module comprises the preceding frame of five metals, glass, the composite wood brightening piece, following diffusion sheet, LGP, heat-conducting glue, LED lamp bar, reflector plate, insulating trip, fender EVA, the five metals backboard utilizes mould that it is carried out punching press, make four joints to reach shape, be respectively five metals backboard A, five metals backboard B, five metals backboard C, five metals backboard D, fixed by screw at last for four sections, to form a complete framework, all there is corresponding cooperation on structure four limits in addition, increase structural strength.And glass is blocked at backboard bending one place, reach the effect of picture center, composite wood brightening piece, following diffusion sheet, LGP, heat-conducting glue, LED lamp bar, reflector plate are positioned at five metals backboard the inside, and heat-conducting glue is attached to below the LED lamp bar, and LED lamp bar 7 is positioned at the groove of five metals backboard B; Reflector plate is positioned at five metals backboard inwall, is LGP above the reflector plate, and the top of LGP is following diffusion sheet, and the top of following diffusion sheet is the composite wood brightening piece, and composite wood brightening piece top is a glass, and glass is embedded in the preceding frame of five metals the inside.
Stick on insulating trip at the glass side.
In the groove of five metals backboard A, five metals backboard B, five metals backboard C, five metals backboard D, be provided with fender EVA.This structure is pulled down screw when safeguarding that the employee reprocesses, and need not tear center open, and is more time saving and energy saving.Lower than before on the material price, the integral product cost reduces by 10%.
The beneficial effects of the utility model are: replace center with the five metals backboard; can strengthen product strength; avoid stress to concentrate and produce the crack or make the crack continue to enlarge; and the employee does industry and avoids assembling center; and be assemblied in the bad also corresponding minimizing of product back segment; the product overall price reduces simultaneously, so, and the easily assembled property of more effective protection display and stability, raising market competitiveness.
