Specific implementation mode
Through inventor the study found that existing color monitor generally obtains coloured silk by red, green, blue three primary colours control technology
Color image, luminescent spectrum wavelength generally in 380-780nm visible-ranges, though for different types of display, spectrum
Power distribution can be variant, but blue light ingredient is generally all relatively prominent (as shown in Figure 1).Currently, for existing LED (Light
Emitting Diode, light emitting diode) display screen mainly use following methods carry out anti-blue light processing, it is specific as follows.
(1) when being packaged to LED light, blue light inhibition material is added directly in packaging plastic, this mode is to downstream
LED display manufacturer most convenient directly uses corresponding LED light, but for encapsulating manufacturer, because being related to LED light classification
The problems such as, a series of lamp of tens models can be had more, cost is caused to be substantially improved, management is also inconvenient.
(2) when using common LED lamp, as shown in Fig. 2, can one layer of filling for inhibiting material containing blue light of embedding on a display screen
Sealing (such as epoxy resin), this mode is for small clearance display screen, and because of gap very little between two lamps, technology difficulty is very
Height, and to trouble light inconvenient maintenance, brightness is influenced also big.
(3) use common LED lamp, finally display screen surface in addition increase by one layer containing blue light inhibit material film or
Tablet, this mode is less problematic to small size display screen, must also splice to large scale display screen, the display screen that leads to that treated
There are planarization, splicing seams, has an effect on display screen heat dissipation.
For the above-mentioned problems in the prior art, a kind of anti-blue light ink of offer of the embodiment of the present invention, display device
10 and its manufacturing method, effectively to solve the above problems.To keep the purpose, technical scheme and advantage of the embodiment of the present invention more clear
Chu, following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiment is a part of the embodiment of the present invention, instead of all the embodiments.Usually here
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations.
Therefore, below the detailed description of the embodiment of the present invention to providing in the accompanying drawings be not intended to limit it is claimed
The scope of the present invention, but be merely representative of the present invention selected embodiment.Based on the embodiments of the present invention, this field is common
The every other embodiment that technical staff is obtained without creative efforts belongs to the model that the present invention protects
It encloses.
It should be noted that：Similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it further need not be defined and explained in subsequent attached drawing in a attached drawing.In description of the invention
In, " first, second, third, fourth etc. is only used for distinguishing description term, and should not be understood as only or imply relative importance.
In the description of the present invention unless specifically defined or limited otherwise, term " setting ", " connected ", " connection " are answered
It is interpreted broadly, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；Can be that machinery connects
It connects, can also be electrical connection；It can be directly connected, can also can be indirectly connected through an intermediary in two elements
The connection in portion.For the ordinary skill in the art, the tool of above-mentioned term in the present invention can be understood with concrete condition
Body meaning.
The embodiment of the present invention provides a kind of anti-blue light ink, and the ingredient of the anti-blue light ink includes 16- hexylene glycol acrylic acid
Fat, urethane acrylate, emulsion, acrylic acid hydrogen chaff ester, blue light inhibit material.Wherein, the anti-blue light ink is one saturating
Bright ink, and there is higher solubility.
When actual implementation, in the present embodiment can by by 16- hexylene glycols acrylate, urethane acrylate, emulsion,
Acrylic acid hydrogen chaff ester and blue light inhibit material to carry out disposable mixing addition and form the anti-blue light ink.
Optionally, the 16- hexylene glycols acrylate, urethane acrylate, emulsion, acrylic acid hydrogen chaff ester, blue light
It is 30%-40% to inhibit the ratio of material：45%-55%：2%-3%：6%-8%：2%-5% in practical applications can root
The ratio of each ingredient is adjusted according to actual demand, the present embodiment is not particularly limited herein.
Further, based on the description to above-mentioned anti-blue light ink, the embodiment of the present invention provides a kind of display device 10,
The display device 10 includes display screen 20 and the anti-blue light ink layer 30 using above-mentioned anti-blue light ink formation, the anti-indigo plant
Gloss oil layer of ink 30 is made in the light-emitting surface of the display screen 20.
In the present embodiment, by directly using anti-blue light ink to form anti-blue light ink layer in the light-emitting surface of display screen 20
30, blue light harm during 20 use of display screen can be significantly reduced, while can effectively avoid in the prior art by viscous
The modes such as patch caused planarization, splicing when the surface of display screen 20 increases the film or tablet of one layer of inhibition material containing blue light
Seam and heat dissipation problem, or it is big etc. by cost increase, technology difficulty caused by the addition blue light inhibition material in casting glue
Problem.
In addition, being tested through inventor proves, when the anti-blue light ink layer 30 for the light-emitting surface for being made in the display screen 20
When thickness is 0.05mm-0.2mm, the blue light weighting spoke brightness L of the blue light harm of the display device 10BIt can decline 20~
30%, but brightness only declines 2~3%, while the heat dissipation effect of display device 10 that the present invention provides is preferable.
Further, due to the present invention by blue light inhibit material and 16- hexylene glycols acrylate, urethane acrylate,
Emulsion and acrylic acid hydrogen chaff ester are disposably mixed to get, and therefore, the synergistic effect between each ingredient enables to make
It is preferable in the consistency of the anti-blue light ink layer 30 on 20 surface of the display screen, it is ensured that the display color of display device 10 is more equal
It is even, and the hardness for handling the anti-blue light ink layer 30 after solidification can reach 7H so that making has the aobvious of anti-blue light ink layer 30
Showing device 10 can not only reduce blue light harm, can also be prevented the surface of display screen 20 using the anti-blue light ink layer 30
Shield.
When actual implementation, since the anti-blue light ink layer 30 can use dedicated solvent to remove, such as ethyl acetate, make
When needing to repair the display device 10, can be directly using as described in being made in such as dedicated solvents such as ethyl acetate
The anti-blue light ink layer 30 on the surface of display screen 20 carries out the repair of display device 10 again after dissolving, it is difficult can effectively to reduce repair
