The problem of light is not soft enough, moreover it is possible to eliminate LED stroboscopic effects, increase LED screen colour developing area and realize pixel puppet super resolution
Change in LED imaging fields, in many cases, the principle of LED arrangement modes and LED screen self-technique in LED display is led
Cause its there are it is natural the defects of, i.e., can not be completely eliminated the gap between display unit, while picture is watched in different angles,
Color is extremely uneven, and image quality is unintelligible, and the soft degree of light of LED is also poor, and LED light source has stroboscopic effect, LED frequencies
Dodge has stimulation to the vision system of people, can produce uncomfortable sensation, and people work or give birth under the light of flicker for a long time
It is living, it is also possible to influence the physiological hygiene and mental hygiene of vision system, deteriorated vision, for LED screen, the luminous point on screen
It is uniformly distributed, issues that light is uniform with homalographic, feeling of fatigue of the people in viewing is also lower.
The technical solution adopted by the present invention is a kind of LED picture quality enhancements film, which includes a substrate, substrate bag
Containing upper and lower surfaces, one layer of the coated on one side of substrate or multilayer optical waveguide layer, optical waveguide layer include lens grain similar in some particle diameters
Son, the refractive index of the lens particle is between 1.2~2.0, if dry lens particle is arranged by triangle or polygon mode, each
LED light corresponds to a pixel, and the size of each lens particle is the 1/2~1/100 of LED light, and lens particle includes incidence surface
And light-emitting surface, incidence surface are to be close to facing directly for substrate, light-emitting surface is raised cambered surface, and multiple bulge-structures are arranged by cycle sequences
Together, ups and downs optical waveguide layer cambered surface is formed, lens particle is made of water white transparency material, and water white transparency material includes glass
The light transmissive polymeric materials such as glass, plastic cement or synthetic material, substrate are transparent plastic-substrates or substrate of glass, and plastic-substrates include
Acrylic, polyesters, vinyl class in polymer.
In order to overcome the deficiencies of the prior art and provide a kind of LED picture quality enhancements film, which can reduce aobvious the present invention
Show the gap between unit, expand the area of hot spot on LED display, the aperture opening ratio of pixel is become larger, improve light and pass through
Effective coverage, the aperture opening ratio of single led display screen is D0, increase on the basis of LED display the present invention film after open
Mouth rate is changed into D1, its relation is D1 ∝ λ D0, wherein, λ is for ratio coefficient and more than 1), and the color allocation of LED imaging pictures is more
Uniformly, pixel puppet super resolution is realized, increase LED screen colour developing area, improves the soft degree of light, make imaged color vividly fresh
Bright, picture is clear, and in addition, which can also eliminate LED stroboscopic effects.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
As shown in Figs. 1-2, a kind of LED picture quality enhancements film, the film include a substrate 20, and substrate is transparent plastics
Substrate or substrate of glass, plastic-substrates include acrylic, and polyesters, vinyl class in polymer, substrate of glass is that general height is saturating
Light glass, usually with relatively low reflectivity, such as glass of the reflectivity below 1%.
Substrate includes upper and lower surfaces, one layer of the coated on one side of substrate or multilayer optical waveguide layer 30, and optical waveguide layer includes some
Lens particle 31 similar in particle diameter, for the refractive index of the lens particle between 1.2~2.0, each LED light corresponds to a pixel
Point, the size of each lens particle 31 are the 1/2~1/100 of LED light, and lens particle 31 includes incidence surface and light-emitting surface, enters light
Face is to be close to facing directly for substrate, and light-emitting surface is raised cambered surface, and multiple bulge-structures are arranged together by cycle sequences, i.e., according to
Certain regular shape cycle arrangement, forms ups and downs optical waveguide layer cambered surface, and lens particle is made of water white transparency material, nothing
Color transparent material includes the light transmissive polymeric material such as glass, plastic cement or synthetic material.
In Fig. 1 shown in C, Fig. 2 is close-up schematic view, the light A that LED screen 10 is sent by some LED light 11, light
A passes through enhanced film, via optical waveguide layer 30, if dry lens particle 31 makes the projected path of light A change, expands light
Dissipate, when light is incident upon receiving screen 40, receiving screen 40 is a kind of optical film projection screen or general projection screen, and projection screen receives
During the projection of light A, under the influence of enhanced film, with reference to figure 4, hot spot effect is under conditions of technical solution of the present invention is implemented
Than not implementing big more of technical solution of the present invention.
As seen in figs. 5-6, if dry lens particle is arranged by triangle or polygon mode, Fig. 3 is the specific reality of the present invention
The lens particle alignment structure chart in example is applied, it can be seen from the figure that every three lens particles, 31 distribution triangular in shape.Fig. 6 is
Multilayered particles arrangement schematic diagram, it can be seen that every three lens particles 31 are also distribution triangular in shape.Triangle is basis, if
Dry triangle can be combined into a hexagon.
As shown in Figure 3-4, the LED picture quality enhancement films of the present invention are implemented, thus it is possible to vary the catalogue of the hot spot B of LED light, leads to
The contrast of Fig. 4 A and 4B is crossed, Fig. 4 B are not plus the hot spot effect before optical thin film, Fig. 4 A are the increase in the light after optical thin film
Spot effect, the film can reduce the gap between display unit, expand the area of hot spot on LED display, make pixel
