Description
Technical field
The utility model belongs to brightness enhancement film field, and in particular to a kind of high printing opacity scratch-resistant brightness enhancement film.
Background technology
Lcd technology because have the advantages that right angle show, low power consumption, small volume, have become today's society most
Universal Display Technique, but liquid crystal as a kind of passive luminescent material, it is necessary to which the display of image could be realized by backlight module.
In general, backlight module includes lower diffusion barrier, lower brightness enhancement film, upper brightness enhancement film, upper diffusion barrier, light guide plate etc..Wherein, brightness enhancement film
Main function be improve liquid crystal display positive brightness.
The backlight module of current main flow is used as blast module, light using the mutual brightness enhancement film up and down in 90 ° of prism structural layer
Line is after lower brightness enhancement film, in the angular field of view that ± 35 ° are concentrated in one direction, during by upper brightness enhancement film, and light is hanging down
Nogata is pooled in ± 35 ° of angular field of view again upwards, so as to realize blast twice, briliancy is greatly improved.Yet with
Brightness enhancement film prism structural layer moves towards single, and a brightness enhancement film is difficult to the luminance gain of space all directions, in order to improve backlight
The uniformity of module displays and brightening effect is maximized, need to typically use the brightness enhancement film of more than two, this not only adds
The thickness of optics module, considerably increases cost.Also, brightness enhancement film typically use sharp right-angle prism, right-angle prism and its
His film contact friction is easily burst apart, and causes the undesirable conditions such as bright spot or blackening occur.
It is described on end, existing optical brightening membrane generally existing not scratch resistance and light loss is big, the relatively low defect of brightness.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high printing opacity scratch resistant increasing
Bright film, with the good performance of light transmittance height, scratch resistance, anti-sticking, shielding.
To achieve these goals, the utility model provides a kind of high printing opacity scratch-resistant brightness enhancement film, including base material, is arranged on
The brightness enhancement layer of base material one side and the adherent layer for being arranged on base material another side, brightness enhancement layer include the first prism and the second prism, described
The cross section of second prism is isosceles triangle, and the cross section of first prism is trapezoidal, and trapezoidal top is provided with diffusion
Particle, the height of first prism is more than the height of the second prism.
Further, the quantity ratio of the first prism and the second prism is 1:2~1:5.
Further, the bottom width of the first prism is 40~50 μm, is highly 20~30 μm.
Further, the trapezoidal side edges of the first prism and bottom angle are 40 °~70 °.
Further, diffusion particle is spheroidal particle, and particle size is 1~10 μm.
Further, the bottom width of the second prism is 20~30 μm, is highly 10~15 μm.
Further, the drift angle of the second prism is 60 °~100 °
Further, base material is polyester film, and thickness is 50~250 μm
Further, the thickness of adherent layer is 3~10 μm.
Compared with prior art, the utility model has the advantages that：
1st, brightness enhancement film of the present utility model is in substrate surface by setting the brightness enhancement layer with the first prism and the second prism,
Optical gain effect of the light in the multiple directions of space can be realized, the show uniformity and light of backlight module is at utmost improved
Multiple brightness enhancement films and diffusion barrier in gain effect, alternative backlight module are learned, the usage quantity of diaphragm is reduced, backlight mould is reduced
Composition is originally.
2nd, because the top using height different the first prism and the second prism, the first prism is provided with diffusion particle, keep away
Exempted from horn structure, reduced the abrasion and scratch between prism and adjacent optical elements, and with it is certain cover, it is scratch resistant
Performance.
Brief description of the drawings
Fig. 1 is the structural representation of the high printing opacity scratch-resistant brightness enhancement film of the utility model；
Wherein, 10 be base material, and 20 be brightness enhancement layer, and 211 be the first prism, and 212 be the second prism, and 213 be diffusion particle, 30
For adherent layer.
