Abstract
The utility model discloses a novel sticky tape is electrically conducted in dedicated two -sided shading of display screen backlight unit, including shading rete, first black extinction conductive adhesive layer, second black extinction conductive adhesive layer, a release film layer and the 2nd release film layer, this first black extinction conductive adhesive layer and second black extinction conductive adhesive layer set up respectively in the upper and lower surface of shading rete, a release film layer and the 2nd release film layer cover respectively in the surface of the surface of first black extinction conductive adhesive layer and second black extinction conductive adhesive layer. By this, set up first black extinction conductive adhesive layer and second black extinction conductive adhesive layer respectively through the upper and lower surface at the shading rete for the light that shines first black extinction conductive adhesive layer, second black extinction conductive adhesive layer and shading rete is by complete absorption, has solved the display screen four sides effectively along abnormal bright border problem appearing, also can play better simultaneously switching on static and to the electromagnetic shield effect in magnetic field.
Description
Technical field
The utility model relates to the tape technology field that electron trade uses, and refers in particular to the two-sided light-shielding conductive adhesive tape that a kind of new-type display screen backlight module is special.
Background technology
Mobile phone, the screened high definition display of the small-sized electronic products such as navigating instrument, the development trends such as the ultra-thin Rimless of product, make backlight module (LCD module, LED module) LED brightness more and more stronger, the overall frame design of backlight module is more and more narrow, the frame that result in backlight module special adhesive tape narrows, due to existing backlight module special adhesive tape structure problem, under LED strong illumination, adhesive tape frame glue-line is because refraction and light reflection, form convergence of rays phenomenon, one or several abnormal bright border is there is at display screen four edge, cause display screen quality abnormal.
In addition, existing because of handset structure adjustment, the electrostatic produce external cause, internal cause and influence of magnetic field, require now to have conductivity with backlight module special adhesive tape, play the effectiveness in electrostatic conducting and magnetic field.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide the special two-sided light-shielding conductive adhesive tape of a kind of new-type display screen backlight module, the performance deficiency that its display backlight module special adhesive tape that effectively can solve small-sized electronic product causes module bright border due to structure and can not conduct electricity.
For achieving the above object, the utility model adopts following technical scheme:
The two-sided light-shielding conductive adhesive tape that new-type display screen backlight module is special, comprises light-shielding film layer, the first black light-absorbing conductive adhesive layer, the second black light-absorbing conductive adhesive layer, the first release film layer and the second release film layer; This first black light-absorbing conductive adhesive layer and the second black light-absorbing conductive adhesive layer are arranged at the upper and lower surface of light-shielding film layer respectively; This first release film layer and the second release film layer are covered in the outside surface of the first black light-absorbing conductive adhesive layer and the outside surface of the second black light-absorbing conductive adhesive layer respectively.
As a kind of preferred version, described first release film layer and the second release film layer are PET single-sided parting film.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
By the upper and lower surface at light-shielding film layer, the first black light-absorbing conductive adhesive layer and the second black light-absorbing conductive adhesive layer are set respectively, the light being irradiated to the first black light-absorbing conductive adhesive layer, the second black light-absorbing conductive adhesive layer and light-shielding film layer is completely absorbed, efficiently solve display screen four edge and occur abnormal bright border problem, also can play conducting electrostatic and the effectiveness to magnetic field better simultaneously.
For more clearly setting forth constitutional features of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the preferred embodiment of the utility model.
Accompanying drawing identifier declaration:
10, light-shielding film layer 20, first black light-absorbing conductive adhesive layer
30, the second black light-absorbing conductive adhesive layer 40, first release film layer
50, the second release film layer.
Embodiment
Please refer to shown in Fig. 1, that show concrete structure of the present utility model, comprise light-shielding film layer 10, first black light-absorbing conductive adhesive layer 20, second black light-absorbing conductive adhesive layer 30, first release film layer 40 and the second release film layer 50.
This light-shielding film layer 10 is containing conductive base, and described conductive base is conductive fabric or conductive metal foil, can select one side shading coating process film or two-sided shading coating process film as required, play adhesive tape complete shading action effect in specific implementation process.
This first black light-absorbing conductive adhesive layer 20 and the second black light-absorbing conductive adhesive layer 30 are arranged at the upper and lower surface of light-shielding film layer 10 respectively, this the first black light-absorbing conductive adhesive layer 20 and the second black light-absorbing conductive adhesive layer 30 are for pasting with backlight module, and absorb LED light source and be irradiated to light on this product, avoid occurring bright border phenomenon, and, play the effectiveness in electrostatic conducting and magnetic field better.
This first release film layer 40 and the second release film layer 50 are covered in the outside surface of the first black light-absorbing conductive adhesive layer 20 and the outside surface of the second black light-absorbing conductive adhesive layer 30 respectively, and described first release film layer 40 and the second release film layer 50 are PET single-sided parting film.This first release film layer 40 and the second release film layer 50 are mainly used in walking around in journey at adhesive tape circle, avoid the first black light-absorbing conductive adhesive layer 20 and the second black light-absorbing conductive adhesive layer 30 bonding mutually.
Design focal point of the present utility model is: arrange the first black light-absorbing conductive adhesive layer and the second black light-absorbing conductive adhesive layer respectively by the upper and lower surface at light-shielding film layer, the light being irradiated to the first black light-absorbing conductive adhesive layer, the second black light-absorbing conductive adhesive layer and light-shielding film layer is completely absorbed, efficiently solve display screen four edge and occur abnormal bright border problem, also can play conducting electrostatic and the effectiveness to magnetic field better simultaneously.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
