Abstract
A wave-shaped self-repairing brightness enhancement film comprises a PET substrate, wherein the front surface of the PET substrate is provided with prism columns, the back surface of the PET substrate is provided with a diffusion layer, a plurality of the prism columns are provided, the prism columns are parallel to one another, each prism column comprises a bottom surface and two side surfaces, each bottom surface is integrated with the front surface of the PET substrate, each pair of the side surfaces extend upwards from the bottom surface in an inclined manner, each pair of the side surfaces intersect at the upper sections to form a peak line, and the peak lines are wave-shaped; and a wave crest and a wave valley on the adjacent prism columns correspond to each other, the height of the peak of each prism column ranges from 24.5 to 26mu m, and the distance between the peak lines of the adjacent prism columns ranges from 49 to 52mu m. According to the wave-shaped 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 brightness enhancement 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: a kind of undaform selfreparing brightness enhancement film, comprise pet substrate, the front of described pet substrate is provided with prism columns, the back side of described pet substrate is provided with diffusion layer, 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.
Further, the angle between the two sides of described prism columns is 90 °.
Beneficial effect of the present invention is: the peak line undulate of prism columns and the 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, and then improve the usability of diaphragm.
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 undaform selfreparing brightness enhancement film, comprise pet substrate 1, the front of described pet substrate 1 is provided with prism columns 2, the back side of described pet substrate 1 is provided with diffusion layer 3, described prism columns 2 is provided with some, 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 formed peak line 6, described peak line 6 undulate; Angle between the two sides 5 of described prism columns is 90 °.
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.
Claims (2)
1. a undaform selfreparing brightness enhancement film, comprise pet substrate, the front of described pet substrate is provided with prism columns, the back side of described pet substrate is provided with diffusion layer, 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.
