Abstract
The utility model discloses optical film, the periphery of the optical film body upper surface or lower surface is printed with light shield layer.Therefore instead of the upper surface that photomask is attached to using glue diffusion membrane body at present.To improve work efficiency, and make the thickness of optical diffusion thin.Therefore, the thickness for reducing the back light including two optical diffusions reaches the thickness for reducing the LED screen using the back light.
Description
Technical field
The utility model is related to optical fields, and in particular to optical film and back light.
Background technology
Optical film is in the backlight for LED screen.To carry out the light in higher, current backlight with the requirement of user
The periphery for learning film needs to paste one layer of light shield layer, and reaching prevents LED screen light leakage.Light shield layer is set on optical diffusion at present, is
Using double faced adhesive tape in the surrounding of optical diffusion, then shading glue being attached to the surface of film so that optical film has shade function,
LED screen is enable to prevent light leakage.But it by the way that after rubberizing, again by the surface of shading sticker optical film, heavy workload can be caused, imitates
Rate is low, and in view of disadvantages described above, it is really necessary to design appliance plug internal frame.
Utility model content
The technical problem to be solved by the utility model is to：Optical film is provided, to solve current current optical film
Shading glue is attached to its periphery by the way of rubberizing, causes the problem that efficiency is low.
In order to solve the above technical problems, the technical solution of the utility model is：Optical film, including optical film matrix, it is described
The periphery of optical film body upper surface or lower surface is printed with light shield layer.
Further, the surrounding of the optics membrane body is printed with the light shield layer.
Further, the width of the light shield layer is 0.08mm-10mm.
Further, the light shield layer is black coating.
A kind of back light including multiple optical films further includes metal end frame, frame, lamp source and light guide plate；It is more
Zhang Suoshu optical films are respectively：Reflectance coating, two bright enhancement films and diffusion barrier；The frame is set to the inside of the metal end frame, institute
It states reflectance coating, the light guide plate, two bright enhancement films and the diffusion barrier to be sequentially overlapped in the metal end frame, the lamp source
Set on one end of the light guide plate.
Further, the light guide plate is formed slopely refraction inlet inwardly close to the top surface of the backlight source；Institute
The length for stating refraction inlet is 1.25mm.
Further, be additionally provided with lower diffusion barrier between the light guide plate and the bright enhancement film, the smooth surface of the lower diffusion barrier or
The periphery of cloudy surface is also printed with lower diffusion barrier light shield layer.
Further, the metal end frame end is also set to the bending part of bending inwardly；The lamp source is placed in the bending
Between portion and the frame.
Further, multiple avoiding hollow grooves of lamp source lamp bead described in empty avoiding are additionally provided on the frame.
Compared with prior art, the optical film is to be printed with screening on the periphery of optical film body upper surface or lower surface
Photosphere.Therefore instead of the upper surface that photomask is attached to using glue diffusion membrane body at present.To improve work efficiency, and
So that the thickness of optical diffusion is thin.Therefore, the thickness for reducing the back light including two optical diffusions reaches reduction
Using the thickness of the LED screen of the back light.When the optical film apply in backlight include multiple optical films back light
When upper so that the back light production efficiency is high, at low cost.
Description of the drawings
Fig. 1 is the structure chart of the utility model optical film；
Fig. 2 is the explosive view of the utility model back light；
Fig. 3 is the three-dimensional view of backlight lamp source part described in the utility model back light；
Fig. 4 is the enlarged view of light guide plate part described in the utility model back light.
Specific implementation mode
Following specific implementation mode will be further illustrated in conjunction with above-mentioned attached drawing.
Hereinafter, a variety of specific details are elaborated, in order to provide the saturating of the concept to constituting described embodiment basis
Thorough understanding.However, it will be apparent to those skilled in the art that described embodiment can be in these no specific details
In some or all situations get off practice.In other cases, well-known processing step is not specifically described.
As shown in Figure 1, optical film, including optical film matrix 1, the week of 1 upper surface of optical film matrix or lower surface
While being printed with light shield layer 2.By being printed with light shield layer 2 on the periphery of 1 upper surface of optical film matrix or lower surface.Therefore it replaces
The current upper surface that photomask is attached to diffusion membrane body using glue.To improve work efficiency.
Further, the surrounding of the optics membrane body 1 is printed with the light shield layer 2.Therefore can meet needs surrounding to keep off
Light or the backlight of shading.
Further, the width of the light shield layer 2 is 0.08mm-10mm.
Further, the light shield layer 2 is black coating.
A kind of back light including multiple optical films 1 further includes metal end frame 3, frame 4, lamp source 5 and light guide plate
6.Multiple described optical films 1 are respectively：Reflectance coating 10, two bright enhancement films 11 and diffusion barrier 12；The frame 4 is set to the metal bottom
The inside of frame 3.The reflectance coating 10, the light guide plate 6, two bright enhancement films 11 and the diffusion barrier 12 are sequentially overlapped described
In metal end frame 3, the lamp source 5 is set to one end of the light guide plate 6.Due to being to print light shield layer 2 on optical film 1, it is
Light shield layer is printed on reflectance coating 10, two bright enhancement films 11 and diffusion barrier 12, therefore instead of in reflectance coating 10, two bright enhancement films, 11 and
Shading glue is pasted on diffusion barrier 12, therefore can effectively improve the production efficiency of reflectance coating 10, two bright enhancement films 11 and diffusion barrier 12, to
Back light assembly working amount is reduced, efficiency is improved, reduces cost.
Further, the light guide plate 6 is formed slopely refraction inlet inwardly close to the top surface of 5 source of the backlight
60；The length of the refraction inlet 60 is 1.25mm.It is led so that the luminous energy of lamp source is irradiated to along refraction inlet 60
In tube sheet.
Further, lower diffusion barrier 13 is additionally provided between the light guide plate 6 and the bright enhancement film 12, the lower diffusion barrier 13
