Description of drawings
Fig. 1 has illustrated the partial cutaway schematic of the module backlight of an embodiment of the present invention; And
Fig. 2 has illustrated the partial cutaway schematic of the module backlight of another embodiment of the present invention.。
The specific embodiment
Hereinafter is to lift the embodiment conjunction with figs. to elaborate; But the embodiment that is provided not is the scope that contains in order to restriction the present invention; And the description of structure running is non-in order to limit the order of its execution; Any structure that is reconfigured by element, the device with impartial effect that produces is all the scope that the present invention is contained.In addition, graphic only for the purpose of description, according to life size mapping.
Please with reference to Fig. 1, Fig. 1 has illustrated the partial cutaway schematic of the module backlight of an embodiment of the present invention.
As shown in Figure 1, module 1 backlight comprises a glue frame 11, a shell 12, a reflector plate 13 and an adhesive tape 14.Glue frame 11 has one first 111 and opposed with it one second 112.Shell 12 in this embodiment, preferably, is iron-clad, and promptly shell 12 employing metallic irons are material, but not as limit, shell 12 also can adopt other material to be made.Reflector plate 13, be arranged on the housing 12 and glue frame 11 under.Adhesive tape 14 has one first end 141 and one second end 142.
In this embodiment, first end 141 of adhesive tape 14 is pasted on first 111 of glue frame 11, and adhesive tape 14 carries out reflexed along the outside A of glue frame 11, makes second end 142 of adhesive tape 14 by second 112 of reflexed to glue frame 11.And in this embodiment, the one side of second end 142 of adhesive tape 14 is pasted on glue frame 11, and another side is pasted on shell 12 and reflector plate 13, thereby makes glue frame 11 and shell 12 fix and glue frame 11 fixes with reflector plate 13.
In this embodiment, adhesive tape 14 preferably, is shading rubber belt (shielding type); In this embodiment, adhesive tape 14 can be two-sided tape, and; Can have release liners or mould release membrance on its two sides, in the time of need pasting, paste after then release liners or mould release membrance being removed.
As shown in Figure 1, module 1 backlight also comprises a LGP 15, an optical thin film 16 and a diaphragm 17 backlight.LGP 15 is arranged on the reflector plate 13; Optical thin film 16 is arranged on the LGP 15, and, first end 141 of adhesive tape 14 extend optical thin film 16 so far above; Diaphragm 17 backlight is arranged on first end 141 of adhesive tape 14.What need explanation is that in this embodiment, module 1 backlight also has other assembly, such as backlight LED, but in order narrating briefly, it not to be narrated or is illustrated among the figure.
To the assembling of module 1 backlight shown in Figure 1 be described below.
At first, facing up and being placed on the glue frame 11 first end 141 of adhesive tape 14;
Then; The release liners or the mould release membrance at the back side of first end 141 of adhesive tape 14 are removed, and first end 141 is pasted on first 111 of glue frame 11 and on the optical thin film 16, be pointed out that; Before pasting, optical thin film 16 and LGP 15 have been assembled on the reflector plate 13.
Afterwards, adhesive tape 14 is carried out reflexed along the outside A of glue frame 11.
Then, the release liners or the mould release membrance in the front of first end 141 of adhesive tape 14 removed, and stick diaphragm 17 backlight.
Then, lean on release liners or mould release membrance of this one side of 11 second 112 of glue frames to remove at second end 142 of adhesive tape 14, and with second 112 bonding mutually of second end 142 with the glue frame 11 of adhesive tape 14.
Afterwards, second end 142 of adhesive tape 14 and the release liners or the mould release membrance of second 112 relative one side are removed, and second end of adhesive tape 14 is binded with fixation reflex sheet 13 with reflector plate 13 mutually.
At last, shell 12 assemblings are got on, and bind with fixed housing 12 with shell 12 through second end 142 of adhesive tape 14 reflexeds.
By on can know, through the adhesive effect of adhesive tape 14, glue frame 11 and reflector plate and glue frame 11 are fixed with shell 12.
Please with reference to Fig. 2, Fig. 2 has illustrated the partial cutaway schematic of the module backlight of another embodiment of the present invention again.
As shown in Figure 2, module 2 backlight comprises a glue frame 21, a shell 22, a reflector plate 23 and an adhesive tape 24.Glue frame 21 has one first 211 and opposed with it one second 212.Shell 22 in this embodiment, preferably, is iron-clad, and promptly shell 22 employing metallic irons are material, but not as limit, shell 22 also can adopt other material to be made.Reflector plate 23, be arranged on the housing 22 and glue frame 21 under.Adhesive tape 24 has one first end 241 and one second end 242.
In this embodiment, first end 241 of adhesive tape 24 is pasted on first 211 of glue frame 21, and adhesive tape 24 carries out reflexed along the inboard B of glue frame 21, makes second end 242 of adhesive tape 24 by second 212 of reflexed to glue frame 21.And in this embodiment, the one side of second end 242 of adhesive tape 24 is pasted on glue frame 21, and another side is pasted on shell 22 and reflector plate 23, thereby makes glue frame 21 and shell 22 fix and glue frame 21 fixes with reflector plate 23.
As shown in Figure 2, module 2 backlight also comprises a LGP 25, an optical thin film 26 and a diaphragm 27 backlight.LGP 25 is arranged on the reflector plate 23; Optical thin film 26 is arranged on the LGP 25.What need explanation is that in this embodiment, module 2 backlight also has other assembly, such as backlight LED, but in order narrating briefly, it not to be narrated or is illustrated among the figure.
Module backlight shown in Figure 22 only is with the difference of module 1 backlight shown in Figure 1, and adhesive tape 24 is that the inboard B along glue frame 21 carries out reflexed, correspondingly; Glue frame 21 has certain difference with glue frame 11; Other assembly and position relation are identical, and be concise and to the point in order to narrate, and repeats no more at this.
By on can know, module backlight proposed by the invention, with first end of adhesive tape binded the unnecessary part (second end) in back carry out reflexed and with reflector plate and the bonding of outer shell facies; So that glue frame and reflector plate and shell stick together, thereby glue frame and reflector plate and shell are fixed, and do not need glue frame and reflector plate and shell be equipped with glue separately; Can reduce cost with this; And,, do not adopt lug trip fixed form for glue frame and shell; Then can not increase the frame area of module backlight, meet the designer trends of current narrow frame.In addition, module backlight proposed by the invention, its adhesive tape, glue frame and shell become one, thereby have improved the problem that adhesive tape (first end) is prone to be raised.。
In the preceding text, illustrate and describe the specific embodiment of the present invention.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop in claims of the present invention institute restricted portion.
