Abstract
An anti-interference composite brightness enhancement film comprises a first substrate layer, a first prism matrix array, a second substrate layer and a second prism matrix array, wherein the first prism matrix array is positioned on the first substrate layer; the prisms on the first prism matrix array are the same as the prisms on the second prism matrix array; an included angle is formed between the prism columns on the first prism matrix array and the prism columns on the second prism matrix array, and the included angle can reduce interference.
Description
Technical Field
The utility model relates to a brightness enhancement film.
Background
The liquid crystal display mainly comprises a liquid crystal panel and a backlight module. The optical film with prism structure is used to concentrate the originally divergent light rays to the axial direction, thereby improving the front brightness of the liquid crystal display. The brightness enhancement film generally adopts an isosceles triangle strip-shaped micro-prism structure, and the front-view accumulation effect and the recycling effect of light rays are generated through the refraction and total reflection of the light rays on the side surfaces of the prisms and multiple times of refraction among the prisms.
Conventional brightness enhancement films are ordered arrays of equally spaced prisms. In the application of the brightness enhancement film in liquid crystal display, the orderly prism array of the brightness enhancement film is superposed with the orderly arranged pixels of the liquid crystal screen to generate interference.
At present, the generation of interference of the brightness enhancement film is always the most critical problem in the liquid crystal display industry.
Disclosure of Invention
In order to overcome the above-mentioned not enough of current brightness enhancement film, the utility model provides a prevent compound brightness enhancement film of interference.
The technical proposal of the utility model for solving the technical problem is that: an anti-interference composite brightness enhancement film comprises a first substrate layer, a first prism matrix array, a second substrate layer and a second prism matrix array, wherein the first prism matrix array is positioned on the first substrate layer;
the prisms on the first prism matrix array are the same as the prisms on the second prism matrix array;
an included angle is formed between the prism row on the first prism matrix array and the prism row on the second prism matrix array.
Furthermore, the longitudinal sections of the prisms on the first prism matrix array and the prisms on the second prism matrix array are both isosceles triangles.
Further, the height of the isosceles triangle is 12-40 μm, the base angle is 30-60 degrees, and the apex angle is 60-120 degrees.
Furthermore, the included angle between the prism columns on the first prism matrix array and the prism columns on the second prism matrix array is 10-15 degrees.
The beneficial effects of the utility model reside in that: an included angle is formed between the prism columns on the first prism matrix array and the prism columns on the second prism matrix array, and the included angle can effectively prevent interference.
Drawings
Fig. 1 is an exploded view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, an anti-interference composite brightness enhancement film comprises a first substrate layer 1, a first prism matrix array 2 located on the first substrate layer 1, a second substrate layer 3 and a second prism matrix array 4 located on the second substrate layer 3, wherein the first prism matrix array 2, the first substrate layer 1, the second prism matrix array 4 and the second substrate layer 3 are sequentially arranged from top to bottom.
The prisms on the first prism matrix array 2 are identical to the prisms on the second prism matrix array 4. In this embodiment, the prisms of the first prism matrix array 2 and the prisms of the second prism matrix array 3 are in the common shapes in the prior art, that is, the longitudinal sections of the prisms are isosceles triangles, the height of the isosceles triangle is 12-40 μm, the base angle is 30-60 °, and the apex angle is 60-120 °.
The prism columns on the first prism matrix array 2 and the prism columns on the second prism matrix array 3 form an included angle, and the included angle is preferably 10-15 degrees.
