Specific embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.Elaborate many details in order to abundant in the following description
Understand the utility model.But the utility model can be implemented with being much different from other manner described here, this area
Technical staff can do similar improvement in the case of without prejudice to the utility model intension, therefore the utility model does not receive following public affairs
The limitation of the specific embodiment opened.
Fig. 1 is referred to, it is the structural representation of bright enhancement film in one embodiment.For example, a kind of bright enhancement film 10 includes increasing
Light prism structure 110 and base material 120, the prism structure 110 that adds lustre to are arranged on base material 120.For example, the material of base material 120 is to wash
Synthetic fibre resin.The prism structure 110 that adds lustre to adds lustre to including some first and prism 111 and some second adds lustre to prism 112, and first adds lustre to rib
Mirror 111 and second prism 112 that adds lustre to are spaced, and the first height for adding lustre to prism 111 adds lustre to the height of prism 112 more than second
Degree, first prism 111 that adds lustre to is provided with flexible glue body 1111 away from the surface of base material, and second adds lustre to table of the prism 112 away from base material
Face is provided with ebonite body 1121.The wherein material surface hardness of flexible glue body 1111 is relatively low, the material surface hardness phase of ebonite body 1121
To height.
Above-mentioned bright enhancement film 10, the prism structure 110 that adds lustre to adds lustre to using some first and prism 111 and some second adds lustre to prism
112, first prism 111 that adds lustre to adds lustre to prism 112 higher than second, and the first surface for adding lustre to prism 111 is provided with flexible glue body 1111,
Second surface for adding lustre to prism 112 is provided with ebonite body 1121, is contacted on bright enhancement film 10 when having external force to act on backlight module
Highly high first is added lustre to prism 111, and the first surface of prism 111 of adding lustre to is provided with flexible glue body 1111, and flexible glue can effectively resist
Resistance to compression is scraped, enables the anti-scratch resistance to compression of bright enhancement film 10, and the second surface of prism 112 of adding lustre to is provided with ebonite body 1121, due to ebonite pair
The refractive index of light is higher than flexible glue, makes the transmitance of light and increases, and makes the efficiency of light energy utilization of anti-scratch resistance to compression bright enhancement film 10 high.
It should be noted that term " first ", " second " are only used for describing purpose, and it is not intended that indicating or implying phase
To importance or the implicit quantity for indicating indicated technical characteristic.Thus, " first " is defined, the feature of " second " can be with
Express or implicitly include at least one this feature.
Additionally, when element is referred to as " being fixed on " or " being arranged at " another element, it can directly in another element
Go up or can also there is element placed in the middle.
For example, refractive index of the refractive index of flexible glue body less than ebonite body.So, by the prism 111 that highly adds lustre to less than first
Do not need the anti-scratch measuring body second surface of prism 112 of adding lustre to that ebonite body 1121 is set, because the refractive index of ebonite is high, send out light source
The light for going out is more by the convergence of ebonite, i.e., partly using the design of flexible glue body 1111 than complete in the prism structure 110 that adds lustre to
Portion increases the utilization rate of luminous energy using the design of flexible glue body 1111.
For example, first adds lustre to and prism 111 and second adds lustre to that prism 112 is arranged in parallel to be arranged on base material 120.For example, phase
The prism 111 or the second that adds lustre to of adjacent first adds lustre to gapless between prism 112 and the contact surface of base material 120.So, it is arranged in parallel
First prism 111 or the second that adds lustre to add lustre to most light that prism 112 sends light source by reflecting reflecting focal one
Rise, increase brightness, improve the utilization rate that light source sends luminous energy.
For example, first add lustre to prism 111 higher than second add lustre to prism 112 height be 2~5 microns.So, there is outer masterpiece
During with backlight module, contacted with bright enhancement film 10 highly high first prism 111 that adds lustre to, and first adds lustre to the table of prism 111
Face is provided with flexible glue body 1111, after adding lustre to the surface of prism 111 by external force first, can voluntarily restore to the original state, and will not be scraped off,
I.e. bright enhancement film 10 will not be damaged.
For example, the two neighboring first the second number of prisms of adding lustre to added lustre between prism is equal.For example, two neighboring first
Add lustre to and at least one is provided between prism 111 second adds lustre to prism 112.Preferably, two neighboring first add lustre to prism 111 it
Between be provided with five second prisms 112 that add lustre to.So, ensure using with anti-scratch resistance to compression effect first add lustre to prism 111 with
On the premise of preventing bright enhancement film 10 from damaging, second add lustre to prism 112 using many refractive indexes are high as far as possible, reduce luminance loss,
Improve the utilization rate of light source.
For example, the first section for adding lustre to prism 111 is triangle.For example, the first section for adding lustre to prism 111 is isosceles three
It is angular.For example, first add lustre to prism 111 away from the corner angle of base material 120 angle be 70~110 degree.Preferably, first adds lustre to rib
Mirror 111 is 90 degree away from the angle of the corner angle of base material 120.For example, the second section for adding lustre to prism 112 is triangle.For example, the
Two sections for adding lustre to prism 112 are isosceles triangle.For example, second prism 112 that adds lustre to is away from the angle of the corner angle of base material 120
70~110 degree.Preferably, second add lustre to prism 112 away from the corner angle of base material 120 angle be 90 degree.So, first adds lustre to rib
Mirror 111 and second add lustre to prism 112 spotlight effect it is best.
Fig. 2 is referred to, it is the structural representation of bright enhancement film in another embodiment, a kind of bright enhancement film 20 includes that first increases
The bright enhancement film 220 of light film 210 and second, the first bright enhancement film 210 is arranged on the second bright enhancement film 220.For example, the first bright enhancement film 210
Also include back coating 211, dorsad the prism structure 110 that adds lustre to is arranged on base material 120 back coating 211.
It is noted that additionally providing a kind of backlight module in an embodiment.
Fig. 3 is referred to, it is the structural representation of backlight module in one embodiment, a kind of backlight module 30 includes black and white
Glue 310, diffusion sheet 320, light guide plate 330, reflector plate 340, lower chase 350, glue frame 360, LED (Light Emitting
