The diaphragm is aperture diaphragm.
The polarizing film is polarization splitting prism.
The polarization splitting prism is formed by a pair of of high-precision right-angle prism gluing, is coated on the bevel edge of one of prism
Polarization spectro deielectric-coating.
Several described light-emitting components are uniformly arranged on array of source plate, the biconvex lens is uniformly arranged on lenticular
On lens array plate, the diaphragm is uniformly arranged on diaphragm array board, the plano-convex lens are uniformly arranged on plano-convex lens array
On plate, the polarizing film be uniformly arranged on polarizing film array board, each array board size is identical, the size and array board of optical filter
It is identical.
The array of source plate, lenticular lens array plate, diaphragm array board, plano-convex lens array board, optical filter, polarizing film
Array board projects direction in light-emitting component light and sets gradually.
The invention has the benefit that face sets gradually biconvex lens, diaphragm, plano-convex lens, optical filtering on light emitting elements
Piece and polarizing film, biconvex lens, diaphragm, plano-convex lens can effectively assemble light, and optical filter makes the light monochromaticjty projected
Good, polarizing film can make the light uniform parallel for injecting display panel.Make liquid crystal display device bright sufficient and nothing in display
Color difference.

Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singular
Also it is intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " packet
Include " when, indicate existing characteristics, step, operation, device, component and/or their combination.
As background technique is introduced, liquid crystal display device, which exists in the prior art, has the problem of color difference, the present invention
Propose a kind of no color differnece liquid crystal display device.
In the typical embodiment of of the invention one, as shown in Figure 1, a kind of no color differnece liquid crystal display device, including liquid
LCD panel and backlight module, backlight module include several light-emitting components 1, along the radiation direction of each light-emitting component 1 according to
Secondary setting biconvex lens 2, diaphragm 3, plano-convex lens 4, optical filter 5 and polarizing film 6.Light-emitting component 1 is LED light source, and diaphragm 3 is hole
Diameter diaphragm, optical filter 5 are crystal optical filter, and the advantages of crystal optical filter is to incude visible light well, prevent infrared ray and
The interference of other light, makes bright in luster true to nature, and polarizing film 6 is polarization splitting prism, and polarization splitting prism is by a pair of of right-angle prism glue
It closes, polarization spectro deielectric-coating is coated on the bevel edge of one of prism.
Each light-emitting component 1 issues light, and biconvex lens 2 all pools the light for the diverging that light-emitting component 1 projects
A little after, by aperture diaphragm 3, aperture diaphragm 3 can most effective control light beam light energy, make for a long time in LED light source in this way
After being reduced with intensity of illumination, light decrease can also assemble luminous energy as far as possible.The light of vertical incidence is formed using plano-convex lens 4
Line, the light of vertical incidence filter some heterogeneous lights after the optical filtering of optical filter 5 and obtain the purer single light of color, produce illumination
Primary colors is kept when raw picture, light enters polarization splitting prism and is divided into the vertical line polarisation of two beams.Wherein P polarisation is completely logical
It crosses, and S polarisation is reflected with 45 degree of angles, exit direction and P light are at an angle of 90 degrees.P polarisation enters display panel.S polarisation enters phase
Adjacent another polarization splitting prism, S polarisation are divided into the vertical line polarisation of two beams again, wherein it is a branch of reflected with 45 degree of angles after and this
The P polarisation of polarization splitting prism enters display panel together, and another beam enters adjacent next polarization splitting prism quilt again
It decomposes.The light of each light-emitting component 1 sending will be into the above process be crossed, and the final light for injecting display panel 7 is parallel equal
Even, pure light.The image for showing display panel 7 does not have color difference.
Several above-mentioned light-emitting components 1 are uniformly arranged on array of source plate, biconvex lens 2 is uniformly arranged on biconvex lens
On array board, diaphragm 3 is uniformly arranged on diaphragm array board, plano-convex lens 4 are uniformly arranged on plano-convex lens array board, are polarized
Piece 6 is uniformly arranged on polarizing film array board, and each array board size is identical, and the size of optical filter 5 is identical as array board.Light source battle array
Strake, lenticular lens array plate, diaphragm array board, plano-convex lens array board, optical filter 5, polarizing film array board are in light-emitting component
Light projects direction and sets gradually, and forms backlight module.The lower section of liquid crystal display panel 7 is arranged in backlight module, is liquid crystal
Show that panel provides light source.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
