Abstract
A brightening composite film is of a layered structure and comprises a diffusion layer and a brightening layer pasted below the diffusion layer. The diffusion layer comprises a first base layer and a lens layer arranged on the first base layer, the brightening layer comprises a second base layer and a prism layer arranged on the second base layer, the lens layer comprises a plurality of semispherical convex lenses, edges of adjacent convex lenses contact, the prism layer comprises a plurality of prisms, edges of adjacent prisms contact, width of each prism is twice that of each convex lens, and each prism is aligned at two corresponding convex lenses. Microstructures are orderly in arrangement, so that light emitted from the lateral side of each prism enters the convex lens on the upper layer, the light is avoided from emitting from gaps among the convex lenses, effect, on light gathering, of the brightening composite film is guaranteed, brightness is improved, and overall luminance of a backlight module is increased. Height of each prism is twice that of the corresponding convex lens, so that the above effect of the brightening composite film is realized while included angles among the prisms are increased as far as possible, and visual angle is increased.
Description
Technical field
The utility model relates to a kind of blooming piece, specifically, is a kind of blast composite membrane.
Background technology
Brightness enhancement film is widely used in illuminating module to be used for converging the light that light source is sent, and especially in the display devices such as display, commonly uses brightness enhancement film, to increase the energy of display brightness and saving display battery apparatus.The principle of brightness enhancement film be by reflection, the light outside directive observer visual angle is adjusted to observer visual angle within, so just improved the utilization factor of luminous energy that light source sends.Liquid crystal panel itself is not luminous, and therefore the backlight module as brightness source is the significant components of LCD Presentation Function, and extremely important for improving LCD brightness.
Existing brightness enhancement film has multiplelayer microstructure, but these microstructures are arranged mixed and disorderly, the light penetrating from lower one deck microstructure can penetrate from the gap of last layer microstructure, raw one deck microstructure cannot further be converged light, thereby make it collect the limited in one's ability of light, make backlight module cannot reach high brightness, briliancy is lower.
Utility model content
The problems such as the utility model is arranged mixed and disorderly for current brightness enhancement film, collect the ability of light, cannot reach high brightness, and briliancy is low, have designed a kind of new blast composite membrane.
Blast composite membrane of the present utility model, for layer structure, comprise diffusion layer and lustre adding layer, lustre adding layer is attached to below diffusion layer, diffusion layer comprises the first basic unit and is arranged on the lens jacket in the first basic unit, lustre adding layer comprises the second basic unit and is arranged on the layers of prisms in the second basic unit, lens jacket comprises several hemispheric convex lens, adjacent convex lens edge contact, layers of prisms comprises several prisms, adjacent prisms edge also contacts, and the width of prism is the twice of convex lens width, and a prism aligns with two corresponding convex lens.
The beneficial effects of the utility model are: the convex lens of blast composite membrane adopts semisphere, the prism width of layers of prisms is the twice of convex lens width, and a prism aligns with two corresponding convex lens, microstructure neat and orderly, make can enter into from the light of each prism sides ejaculation the convex lens on upper strata, avoid light directly from the gap between convex lens, to penetrate, guaranteed the converge effect of blast composite membrane to light, improve brightness, increased the briliancy of backlight module integral body.The height of prism is the twice of convex lens height, when making blast composite membrane reach above-mentioned effect, has increased as much as possible the angle between prism, has improved visible angle.
Accompanying drawing explanation
Accompanying drawing 1 is the structural drawing of blast composite membrane.
Embodiment
Blast composite membrane of the present utility model, is layer structure, as shown in Figure 1, comprises diffusion layer 1 and lustre adding layer 2, and lustre adding layer 2 is attached to below diffusion layer 1.
Diffusion layer 1 comprises the first basic unit 3 and is arranged on the lens jacket 4 in the first basic unit 3, lustre adding layer 2 comprises the second basic unit 5 and is arranged on the layers of prisms 6 in the second basic unit 5, lens jacket 4 comprises several hemispheric convex lens 7, adjacent convex lens 7 edge contact, layers of prisms 6 comprises several prisms 8, and adjacent prisms 8 edges also contact.
A prism 8 aligns with two corresponding convex lens 7, and the width of prism 8 is the twice of convex lens 7 width, and a side of each prism 8 is alignd with a convex lens 7, and then the light that makes to penetrate from prism 8 one sides all can enter into convex lens 7 and converges.The height of prism 8 is also the twice of convex lens 7 height, can make the angle between prism 8 reach 90 degree, when guaranteeing light convergence effect, has increased as much as possible visible angle.
