Abstract
The utility model discloses a dotted type positioning rubber-iron integrated LED (light-emitting diode) backlight. The LED backlight comprises a rubber-iron component, a reflective piece, a rubber frame, a light guide plate (LGP), a lower brightness enhancement piece, an upper brightness enhancement piece, a shading piece and an LED light-emitting component on the side edge, wherein the rubber-iron component comprises an iron frame and the rubber frame embedded in the iron frame, and the iron frame and the rubber frame are in an integrated structure, and the periphery of the iron frame is uniformly provided with four or above holes with round structures. Compared with the prior art, the dotted type positioning rubber-iron integrated LED backlight provided by the utility model has simple structure and reliable quality, is convenient to process, saves the process and the cost and well satisfies the requirement on ultrathin LED backlights currently.
Description
Technical field
The utility model relates to a kind of use for electronic products backlight, particularly relates to a kind of circle dot mode location glue iron integral LED backlight.
Background technology
Characteristics such as the LED-backlit source is meant the backlight that is used as LCDs with LED, compares with traditional CCFL (cold-cathode tube) backlight, and LED has low-power consumption, lower calorific value, brightness is high, the life-span is long.LED is the use that can replace colored filter as the advantage of backlight.After 07 year; LED is asked to do thinner and thinner, when adopting 0.44mm and following LGP (LGP), glue frame, chase, and backlightly just becomes very softly; Cause the easily loosening or assembling process of chase to be prone to cause problems such as distortion, like the assembling mode that adopts bending legs machine that the metal leg on the chase is twisted and warped.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of circle dot mode reliable, that save operation and cost simple in structure, easy to process to locate glue iron integral LED backlight, satisfies the ultra-thin demand to LED.
In order to achieve the above object; The technical scheme that the utility model adopts is: a kind of circle dot mode location glue iron integral LED backlight; Comprise successively from back-to-front: glue iron component, reflector plate, glue frame, LGP, diffusion sheet, time brightening piece, last brightening piece, anti-dazzling screen; And the LED luminescence component of side, said glue iron component comprises chase and is embedded in the glue frame in the chase, and chase and glue frame are integral structure.
The periphery of said chase evenly is provided with 4 and above circular configuration hole.
Compared with prior art, the utility model is simple in structure, easy to process, save operation and cost, and is of fine qualities, saved raw material, reduced cost, satisfied now the market demand to the ultra-thin LED backlight well.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Shown in the figure: 1-glue iron component; 11-glue frame; The 12-chase; The 13-structure hole; The 2-reflector plate; The 3-LGP; The 4-LED luminescence component; The 5-diffusion sheet; Brightening piece under the 6-; The last brightening piece of 7-; The 8-anti-dazzling screen.
The specific embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.
The structural representation of the utility model is as shown in Figure 1; A kind of circle dot mode location glue iron integral LED backlight; Comprise successively from back-to-front: glue iron component 1, reflector plate 2, LGP 3, diffusion sheet 5, time brightening piece 6, last brightening piece 7, anti-dazzling screen 8; And the LED luminescence component 4 of side, said glue iron component 1 comprises chase 12 and is embedded in the glue frame 11 in the chase 12, and chase 12 is an integral structure with glue frame 11.
Glue iron component 1 adopts the vertical injection molding machine moulding, and chase 12 is used the punching process forming earlier, and the chase 12 with forming utilizes mould to carry out the quadric injection mould moulding on vertical (being generally vertical injection molding machine) injection machine again.Glue iron component 1 has solved backlight glue frame 11 well and has cooperated not tight problem with chase 12, has improved production efficiency, and has cancelled glue frame 11 and chase 12 these one procedure of assembling, further reduces production costs.
For the glue frame 11 that guarantees glue iron component 1 has good flatness after injection mo(u)lding, prevent that glue frame warpage is uneven, the periphery of said chase 12 evenly is provided with 4 and above circular configuration hole 13.The glue frame 11 of this glue iron component 1 adopts URZ2501 (Japanese import Merlon) material; It is SUS304 (the Japanese import stainless steel) material of 0.2mm that chase 12 adopts thickness, and chase 12 can be gone out 4 and above circular configuration hole 13 at its periphery when the stamping-out moulding; The mould that then that stamping-out is good chase 12 is put into vertical injection molding machine carries out injection moulding; The diameter of structure hole 13, spacing and can change according to the product size size to the distance at chase 12 edges are example with 4.0 inches backlight products, and the appearance and size of product is: long 82.54mm; Wide 54.5mm; Structure hole diameter on the side chase is 0.7 millimeter, and the spacing of structure hole 13 generally designs between 47 millimeters, and structure hole 13 is between the 2-4 millimeter to the distance at chase 12 edges.
After injection moulding was accomplished, glue frame 11 tightly was sticky in chase 12, is integrally formed the glue iron component 1 of formula structure; Saved the assembly process of chase 12 and glue frame 11, and, both guaranteed that glue frame 11 was can warpage after moulding not uneven when injection moulding because part glue frame 11 is embedded in the structure hole 13 of chase 12; The flatness that effectively satisfies product requires (0.3mm); Can increase the sticking glutinous firmness between chase 12 and the glue frame 11 again, realize ultra-thinization of product, densification.
The content of mentioning in the foregoing description is not to be the qualification to the utility model, and under the prerequisite of the inventive concept that does not break away from the utility model, and any conspicuous replacement is all within the protection domain of the utility model.
