Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] refer to figure 1 , a self-repairing brightness enhancement film, comprising a PET substrate 1, the front of the PET substrate 1 is provided with a prism column 2, and the back of the PET substrate 1 is provided with a diffusion layer 3, and the haze of the diffusion layer is 3 to 5 %. The general diffusion layer in the prior art can be used as the diffusion layer. Generally, the diffusion particles are heated in the coating liquid, and then the coating liquid is coated on the back side of the PET substrate.

[0013] The prism column 2 is provided with several pieces, and it is recommended that the prism column is processed by an ultrasonic servo oscillator, the oscillation frequency of which is 20KHz, and of course, the prism column can also be formed by using the existing technology. Each prism column 2 is parallel to each ...

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, 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; 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; and the back surface of the PET substrate is provided with a diffusion layer, and haze of the diffusion layer ranges from 3 to 5%. 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 [0001] The invention relates to a self-repairing brightness enhancing film. Background technique [0002] At present, the self-healing brightness enhancement film is widely used in the backlight module to gather the light emitted by the light source, especially in display devices such as flat panel liquid crystal displays, so as to increase the brightness of the display and save the energy of the display. The principle of the self-healing brightness enhancement film is the principle of refraction and reflection of general light, which refracts the light from outside the observer's viewing angle to the observer's viewing angle, thus improving the brightness of the display and the utilization of the light source. The uniformity of light distribution and anti-interference ability of existing self-healing incremental films need to be improved. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing self-repairin...
