Abstract
The two-sided shading rubber belt that a kind of new-type display screen backlight module is special, relate to the tape technology field that electron trade uses, solve the display backlight module special adhesive tape of small-sized electronic product due to textural defect, tape edge is caused to occur the technical deficiency of bright border, described adhesive tape includes PET light-shielding film layer, the two sides of PET film layer are provided with black light-absorbing adhesive-layer, and the skin of two black adhesive-layers is provided with release film layer.The utility model is provided with black light-absorbing adhesive-layer in the two sides of PET light-shielding film layer, and the light being irradiated to black light-absorbing adhesive-layer and PET light-shielding film layer is completely absorbed, and innovatively solves display screen four edge and occurs abnormal bright border problem.
Description
Technical field
The utility model relates to the tape technology field that electron trade uses, and relates in particular to the small-sized electronic product such as mobile phone, navigating instrument display backlight module special adhesive tape technical field.
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 problem off quality.
Utility model content
In sum, the purpose of this utility model is that the display backlight module special adhesive tape solving small-sized electronic product is due to textural defect, cause tape edge to occur the technical deficiency of bright border, and propose the special two-sided shading rubber belt of a kind of new-type display screen backlight module.
For solving the technical problem that the utility model proposes, the technical scheme adopted is: the two-sided shading rubber belt that a kind of new-type display screen backlight module is special, it is characterized in that described adhesive tape includes PET light-shielding film layer, the two sides of PET film layer are provided with black light-absorbing adhesive-layer, and the skin of two black adhesive-layers is provided with release film layer.
Described black light-absorbing adhesive-layer is the ancient river board tackiness agent comprising special extinction additive.
Described release film layer is PET single-sided parting film.
The beneficial effects of the utility model are: the utility model is provided with black light-absorbing adhesive-layer in the two sides of PET light-shielding film layer, the light being irradiated to black light-absorbing adhesive-layer and PET light-shielding film layer is completely absorbed, and innovatively solves display screen four edge and occurs abnormal bright border problem.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific examples of the utility model, structure of the present utility model is further described.
With reference to shown in Fig. 1, the utility model includes from top to bottom successively: the first release film layer 1, first black light-absorbing adhesive-layer 2, PET light-shielding film layer 3, second black light-absorbing adhesive-layer 4, second release film layer 5.
Bonding for backlight module of first black light-absorbing adhesive-layer 2 and the second black light-absorbing adhesive-layer 4, for comprising the ancient river board tackiness agent of extinction additive; Be mainly used in absorbing LED light source and be irradiated to light on the utility model adhesive tape, avoid occurring bright border phenomenon.
PET light-shielding film layer 3 is shading base material, 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.
First release film layer 1 and the second release film layer 5 are main to be convenient to walk around in journey at adhesive tape circle, avoid the first black adhesive-layer 2 and the second black adhesive-layer 4 bonding mutually, release film layer is preferably PET single-sided parting film.
