According to the self-repairing brightness enhancement film, the peak lines of the prism columns are wave-shaped, and the wave crest and the wave valley on the adjacent prism columns correspond to each other, thus a double-wave-shaped prism mechanism is formed, the light distribution uniformity of the brightness enhancement film can be increased, and the anti-interference capability of the brightness enhancement film is improved.
Description
Technical field
The present invention relates to a kind of selfreparing brightness enhancement film.
Background technology
At present, selfreparing brightness enhancement film is widely used in backlight module, is used for converging the light that sends of light source, especially in the display devices such as plate of flat liquid crystal display, to increase the brightness of display and to save the energy of display.The principle of selfreparing brightness enhancement film is the refraction of general light and the principle of reflection, within the light refraction outside directive observer visual angle to observer visual angle, which improves the brightness of display and the utilization factor of light source.Photodistributed homogeneity and the antijamming capability of existing selfreparing increment film have much room for improvement.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing selfreparing brightness enhancement film, the invention provides a kind of photodistributed homogeneity and antijamming capability better undaform selfreparing brightness enhancement film.
The technical scheme that the present invention solves its technical matters is: 1. selfreparing brightness enhancement film, comprise pet substrate, the front of described pet substrate is provided with prism columns, it is characterized in that: described prism columns is provided with some, every bar prism columns is parallel to each other, every bar prism columns all has a bottom surface, two sides, the front of described bottom surface and described pet substrate is integral, two described sides extend obliquely from described bottom surface, and two sides are intersected at epimere thus are formed peak line, described peak line undulate;
Crest on adjacent prisms post is corresponding with trough, and the height of the peak of every bar prism columns is 24.5 ~ 26 μm, and the distance between the peak line of adjacent prisms post is 49 ~ 52 μm;
The back side of described pet substrate is provided with diffusion layer, and the mist degree of this diffusion layer is 3 ~ 5%.
Further, the angle between the two sides of described prism columns is 89 °.
Further, described prism columns adopts ultrasound wave servo oscillation device to process, and the oscillation frequency of ultrasound wave servo oscillation device is 20KHz.
Beneficial effect of the present invention is: the peak line undulate of prism columns, and crest on adjacent prisms post is corresponding with trough, form two corrugated prism mechanism, the photodistributed homogeneity of brightness enhancement film can be improved, add the antijamming capability of brightness enhancement film, improve resistance to scraping and the brightness gain values of brightness enhancement film, its back side being coated with diffusion layer can by light scattering, interference between blooming piece can be destroyed to alleviate Newton ring phenomenon when being applied to backlight module, the effect of coverage or hidden defects can be reached, the double effects of diffusion and blast can be reached, and then improve the function of blooming piece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, a kind of selfreparing brightness enhancement film, comprises pet substrate 1, and the front of described pet substrate 1 is provided with prism columns 2, and the back side of described pet substrate 1 is provided with diffusion layer 3, and the mist degree of this diffusion layer is 3 ~ 5%.Diffusion layer adopts general diffusion layer of the prior art, is generally to adopt in coating fluid, to heat diffusion particle, then by the back side of coating solution to pet substrate.
Described prism columns 2 is provided with some, and recommend described prism columns to adopt ultrasound wave servo oscillation device to process, the oscillation frequency of ultrasound wave servo oscillation device is 20KHz, certainly also can adopt prior art machine-shaping prism columns.Every bar prism columns 2 is parallel to each other, every bar prism columns 2 all has side 5,4, two, a bottom surface, described bottom surface 4 is integral with the front of described pet substrate 1, two described sides 5 extend obliquely from described bottom surface, and two sides 5 are intersected at epimere thus are formed peak line 6, described peak line 6 undulate; Angle between the two sides 5 of described prism columns is 89 °.
Crest on adjacent prisms post is corresponding with trough, and namely using adjacent two prism columns as the object of observation, the trough in the prism columns that the crest in a prism columns is adjacent is relative, and the crest in the prism columns that the trough in this prism columns is adjacent is relative.
The height of the peak of every bar prism columns 2 is 24.5 ~ 26 μm, and the distance (distance namely between the projection of peak line on pet substrate) between the peak line 6 of adjacent prisms post is 49 ~ 52 μm.
