Description
Technical field
The utility model is related to module group backlight technical field, and in particular to a kind of light guide plate of the highlighted ultra-narrow without bright border.
Background technology
At present, module group backlight is generally adopted by light guide plate and reflector plate that LED spot light is changed into luminance loss is few
Area source, often occur that bright line occur in light guide plate two sides and afterbody in the process, this is that backlight industry compares headache
The problem of, the edge bright line of backlight has had a strong impact on the visual effect of module, while becoming the process of area source in this spot light
Loss occurs in middle brightness, so as to need to improve the finished product brightness of backlight by improving the blast membrane material of other high configurations, enters
And significantly increase production cost.
Utility model content
The utility model eliminates edge bright line, and drop to solve the above mentioned problem of prior art presence there is provided one kind
Light guide plate of the highlighted ultra-narrow without bright border for the luminance loss that light guide plate is present in low transfer process.
Above-mentioned purpose is realized, the utility model provides a kind of light guide plate of the highlighted ultra-narrow without bright border, including light guide plate sheet
Body, site film and planar film, the light conducting plate body are ultra-thin tetragonal body, and the site film is moulded in removing for light conducting plate body
On the other three side beyond light incident sides, the site film is provided with some hemispheric grooves, and the top court of groove
To light conducting plate body, the ray refractive index of the site film is n1, and the planar film is moulded in the site film of three sides
Outer surface, and light conducting plate body lower surface, the ray refractive index of the planar film is n2, and n1 is more than n2.
It is used as preferred scheme of the present utility model, it is characterised in that the injection liquid that the site film injection moulding process is used
For acrylic mixed liquor.
As preferred scheme of the present utility model, the thickness of the planar film is 0.1mm.
Light guide plate of the highlighted ultra-narrow without bright border of the present utility model can reach following beneficial effect：
Light guide plate of the highlighted ultra-narrow without bright border of the present utility model, by including light conducting plate body, site film and planar film,
The light conducting plate body be ultra-thin tetragonal body, the site film be moulded in light conducting plate body in addition to light incident sides in addition
On three sides, the site film be provided with some hemispheric grooves, and groove top towards light conducting plate body, the net
The ray refractive index of point film is n1, and the planar film is moulded in the site film outer surface of three sides, and light guide plate sheet
The lower surface of body, the ray refractive index of the planar film is n2, and n1 is more than n2 so that the utility model will be led by site film
The light diverging at tabula rasa edge is so as to avoid the appearance of bright border, simultaneously because the material with 2 kinds of refractive indexes so that when light is mapped to
It will be totally reflected during interface, the reflected light after total reflection is reflected back again just can improve the brightness of light-emitting area, so that
Highlight effect has been reached, and production cost is low, effect is good.
Brief description of the drawings

The structural representation for the example that Fig. 1 provides for light guide plate of the highlighted ultra-narrow of the utility model without bright border.
Fig. 2 is the fundamental diagram of site film in light guide plate of the highlighted ultra-narrow of the utility model without bright border.
Fig. 3 be light guide plate of the highlighted ultra-narrow of the utility model without bright border in be totally reflected fundamental diagram.
In figure：1st, light conducting plate body, 2, site film, 3, planar film, a, incident light, b, reflected light, c, refraction light, are all-trans at d
Penetrate light.
The utility model purpose is realized, functional characteristics and advantage will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.In preferred embodiment
Cited such as " on ", " under ", "left", "right", only " centre " and " one " term, understanding for ease of narration, and be not used to
The enforceable scope of the utility model is limited, being altered or modified for its relativeness is changed under technology contents without essence, when also
It is considered as the enforceable category of the utility model.
The structural representation for the example that Fig. 1 provides for light guide plate of the highlighted ultra-narrow of the utility model without bright border, such as Fig. 1 institutes
Show, light guide plate of the highlighted ultra-narrow without bright border includes light conducting plate body 1, site film 2 and planar film 3, and the light conducting plate body 1 is super
Thin tetragonal body, the site film 2 is moulded on the other three side in addition to light incident sides of light conducting plate body 1, described
Site film 2 is provided with some hemispheric grooves, and groove top towards light conducting plate body 1, the light of the site film 2 is rolled over
Rate is penetrated for n1, the planar film 3 is moulded in the outer surface of site film 2 of three sides, and light conducting plate body 1 following table
Face, the ray refractive index of the planar film 3 is n2, and n1 is more than n2.
In specific implementation, it is characterised in that the injection liquid that the injection moulding process of site film 2 is used mixes for acrylic
Liquid.
Specific implementation, the thickness of the planar film 3 is 0.1mm.
In order to allow those skilled in the art to more fully understand and realize the technical solution of the utility model, brief description sheet
The realization principle of embodiment.
Fig. 2 is the fundamental diagram of site film 2 in light guide plate of the highlighted ultra-narrow of the utility model without bright border, as shown in Fig. 2
Because site film 2 is provided with some hemispheric grooves, when the light in light conducting plate body 1 is projected from edge, light irradiation
To interface, its arcuate structure, by the incident light a of same angle, is reflected back in light guide plate, realizes reflected light at different angles
B diverging, it is to avoid the appearance of bright border.The light of site film 2 is irradiated in addition, and a part is outer by reflection, and another part can be rolled over
Penetrate.Fig. 3 is is totally reflected fundamental diagram in light guide plate of the highlighted ultra-narrow of the utility model without bright border, as shown in figure 3, due to plane
The ray refractive index of film 3 is less than the ray refractive index of site film 2, and the refraction light c that site film 2 is reflected reaches planar film 3 and net
During the interface of point film 2, it may occur that total reflection is penetrated, total reflection light d make it that the light is reflected back in light conducting plate body 1, so as to carry
The high brightness of light guide plate light-emitting area, so as to reach highlighted effect.
Although the foregoing describing embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely illustrative of, and can make various changes or modifications to present embodiment, without departing from original of the present utility model
Reason and essence, protection domain of the present utility model are only limited by the claims that follow.
