Abstract

The invention discloses the full frame special shaped LED backlights of mobile phone; including light guide plate, reflectance coating, protective film, diffusion barrier, under add lustre to, on add lustre to, shading glue, rubber shell, LED component, FPC double-sided adhesive and FPC; wherein: be successively arranged on the light guide plate diffusion barrier, under add lustre to, on add lustre to and shading glue, be successively arranged reflectance coating and protective film under light guide plate.The present invention is by effectively solving the whole partially dark and R corner reflection light angle fringe R tactical rule in U-shaped side and changing, cause luminance area that brightness irregularities are presented by the way that micro-prism structure is arranged in two side bottom of U structure and UV is cooperated to irradiate；By the way that distance of the VA vision area of reasonable shading glue apart from backlight shape is arranged, solve the problems, such as that optical film material contraction causes optical edge bright line.

Description

The full frame special shaped LED backlight of mobile phone
Technical field
The present invention relates to LED backlight technical field more particularly to the full frame special shaped LED backlights of mobile phone.
Background technique
The invention of full frame abnormity backlight greatly improves the visible area range of backlight, and appearance increases difference The angle C or U-shaped structure in routine " rectangle ", visible area accounting shape area are promoted by 70% to 90% or more.But it exists simultaneously Following drawback: the U-shaped side reflected light angle of light guide plate increases, and causes U-shaped side whole partially dark；R corner reflection light angle fringe R structure Rule variation, causes luminance area that brightness irregularities are presented；And requirement of the full frame abnormity for ultra-narrow border structure is stringenter, The width and rigidity that should guarantee frame avoid optical film material contraction from causing optical edge bright line again.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of full frame special shaped LED backlight of mobile phone.
Technical scheme is as follows: mobile phone full frame special shaped LED backlight, including light guide plate, reflectance coating, protection Film, diffusion barrier, under add lustre to, on add lustre to, shading glue, rubber shell, LED component, FPC double-sided adhesive and FPC, in which: on the light guide plate Be successively arranged diffusion barrier, under add lustre to, on add lustre to and shading glue, be successively arranged reflectance coating and protective film, light guide plate one under light guide plate Side panel is equipped with FPC, and the other side is equipped with U-shaped structure, and the FPC is fixedly mounted on light guide plate by FPC double-sided adhesive, guide-lighting Plate side parallel position is equipped with LED component, and the LED component is fixedly mounted in rubber shell, light guide plate, reflectance coating, protective film, expansion Dissipate film, under add lustre to, on add lustre to, shading glue pressing after be mounted in rubber shell, the U-shaped structure two sides of the bottom be equipped with microprism knot Structure, the micro-prism structure are irradiated using UV, and the light-emitting surface of light guide plate is equipped with R structure, and the depth of the R structure is 0.17mm, Angle is 90 °, and site is also distributed on light guide plate, and the site diameter is 45 μm, and depth is 0.5 μm, and close in the thin tail of head Curvilinear motion.
Preferably, distance of the VA vision area of the shading glue apart from backlight shape is 0.32mm.
Technical effect and advantage of the invention: by the way that micro-prism structure is arranged in two side bottom of U structure and UV is cooperated to irradiate, It effectively solves the whole partially dark and R corner reflection light angle fringe R tactical rule in U-shaped side to change, causes luminance area that brightness is presented Unevenly；By the way that distance of the VA vision area of reasonable shading glue apart from backlight shape is arranged, solves optical film material contraction and cause light Learn the problem of edge bright line.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of light guide plate of the invention.
Fig. 3 is the U-shaped structure schematic diagram of light guide plate of the invention.
In figure: add lustre under 1 light guide plate, 2 reflectance coatings, 3 protective films, 4 diffusion barriers, 5, add lustre on 6,7 shading glues, 8 rubber shells, 9LED component, 10FPC double-sided adhesive, 11FPC, 12U type structure, 13 micro-prism structures, 14R structure, 15 sites.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the full frame special shaped LED backlight of mobile phone, including light guide plate 1, reflectance coating 2, protective film 3, diffusion barrier 4, add lustre to 5 under, on add lustre to 6, shading glue 7, rubber shell 8, LED component 9, FPC double-sided adhesive 10 and FPC11, in which: the light guide plate 1 On be successively arranged diffusion barrier 4, under add lustre to 5, on add lustre to 6 and shading glue 7, be successively arranged reflectance coating 2 and protective film 3 under light guide plate 1, 1 side panel of light guide plate is equipped with FPC11, and the other side is equipped with U-shaped structure 12, and the FPC11 passes through the fixed peace of FPC double-sided adhesive 10 On light guide plate 1,1 side parallel position of light guide plate is equipped with LED component 9, and the LED component 9 is fixedly mounted in rubber shell 8, Light guide plate 1, reflectance coating 2, protective film 3, diffusion barrier 4, under add lustre to 5, on add lustre to after 6, shading glue 7 presses and be mounted in rubber shell 8, institute 12 two sides of the bottom of U-shaped structure are stated equipped with micro-prism structure 13, the micro-prism structure 13 is irradiated using UV, most of by collecting Polymorphic structure reflected light promotes homogeneity, and the light-emitting surface of light guide plate 1 is equipped with R structure 14, and the depth of the R structure 14 is 0.17mm, angle are 90 °, and site 15 is also distributed on light guide plate 1, and 15 diameter of site is 45 μm, and depth is 0.5 μm, and And in head dredge the close curvilinear motion of tail, have the effect of it is best, by change light diffusing reflection, promotion curved surface brightness uniformity it is reachable Surface uniformity 80%min, 85%typ.
Further, distance of the VA vision area of the shading glue 7 apart from backlight shape is 0.32mm, it is ensured that rubber shell 8 Rigidity and intensity while, avoid optical film material contraction cause bright line.
