Description
Technical field
The utility model relates to liquid crystal module, particularly for liquid crystal module light-source structure.
Background technology
Current LCD backlight module adopts white light LEDs to form line source usually, by light guide plate, brightness enhancement film, even smooth film, line source is converted to area source, then realizes image frame display by liquid crystal panel.Above-mentioned entirety as the back light of liquid crystal module, for passive luminophor liquid crystal panel provides luminous energy.The white light generated due to LED backlight needs through multilayer optical device to the visible display panels of human eye, each optical element has can have absorption to light, light source proximal end region and light source remote area, due to light transmition distance not etc., variant to the ratio of different-waveband energy absorption, cause the difference of different viewing areas color.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of liquid crystal module light-source structure, promotes the color gamut space of liquid crystal module display color, promotes the color consistency of the zones of different of liquid crystal display module.
For solving the problem, the technical solution adopted in the utility model is: liquid crystal module light-source structure, comprises liquid crystal panel, membrane combination, light wave conversion film, light guide plate and is arranged on the backlight of light guide plate side; Described membrane combination is between liquid crystal panel and light guide plate; Described light wave conversion film is arranged between described liquid crystal panel and membrane combination; Described light wave conversion film comprises PET base material and can realize the nanocrystal of light wave conversion, and described nanocrystal is coated in described PET base material; Described backlight is single-range monochromatic source.
Further, described membrane combination is made up of brightness enhancement film and even smooth film.
Further, described monochromatic source is blue-ray LED, and described light wave conversion film is the light wave conversion film that blue light can be converted to RGB light.
The beneficial effects of the utility model are: when single band blue light is propagated between light guide plate, reflecting paper, brightness enhancement film, even smooth film, owing to only there being a kind of visible light spectrum of wave band, can not cause multiband spectrum in communication process because the absorptivity of different wave length is inconsistent and cause zones of different color situation devious; Blue light generates after red-green-blue through light wave conversion film, using the direct backlight as liquid crystal panel, no longer pass through other optical component, look degree of depositing high, the different backlight area chromaticity coordinates consistance in this backboard source is good, therefore the utility model can realize high colour gamut and chromaticity coordinates consistance excellent liquid crystal module display.

Number in figure: back board module 1, lamp bar heat sink 2, blue LED lamp bar 3, reflecting paper 4, light guide plate 5, membrane combination 6, light wave conversion film 7, enclose frame assembly 8, liquid crystal panel 9.
Embodiment
The utility model adopts the two poles of the earth light source as the light-source structure of liquid crystal module.First, adopt blue LED lamp bar as first order light source, under the driving of electric current, realize electro-optic conversion, generate single band blue light line source; Blue-ray LED line source is converted to blue light area source by light guide plate, reflecting paper; Adopt diffusion barrier and brightness enhancement film by further for blue light area source homogenising, and promote the brightness of main perspective and subjective image quality effect; Then, by the aforementioned single band blue light area source generated, excitation light wave conversion film, light is by the visible ray of light wave conversion film release three primary colours RGB corresponding wavelength, three primary colours mixing realizes the white backlight source being used for liquid crystal module display, and therefore light wave conversion film is as second level light source.
As Fig. 1, the liquid crystal module light-source structure designed by embodiment, comprises back board module 1, lamp bar heat sink 2, blue LED lamp bar 3, reflecting paper 4, light guide plate 5, membrane combination 6, light wave conversion film 7, encloses frame assembly 8, liquid crystal panel 9.Wherein, light wave conversion film is nanocrystal photoluminescent film, and its technique is the nanocrystal that in PET base material, coating can realize light wave conversion.
Back board module 1 provides the large backboard plane of satisfied certain flatness requirement, for other part fixedly provides basis; Lamp bar heat sink 2 is fixed on one end of backboard by screw, the mode that blue LED lamp bar 3 adopts importing adhesive tape or screw to fix is fixed on the flange of lamp bar heat sink 2; Reflecting paper 4 is positioned on back board module 1 and lamp bar heat sink 2; Light guide plate 5 is positioned in reflecting paper, is undertaken spacing by the hard jacking block a little more than LED lamp bead light-emitting area in the profile of back board module 1 and blue LED lamp bar 3; Membrane combination 6 is positioned in light guide plate 5, is fixed on backboard flange by the hangers on diaphragm top, and wherein, membrane combination 6 is generally made up of brightness enhancement film and even smooth film; Light wave conversion film 7 is positioned in membrane combination 6, is fixed on backboard flange by the hangers on diaphragm top; Enclose the mode that frame assembly 8 adopts clamping or screw to lock to be fixed on the flange of back board module.To sum up, back board module 1 and enclose structural member such as frame assembly 8 grade and form a complete cavity, support blue LED lamp bar 3, reflecting paper 4, light guide plate 5 and membrane combination 6 and limit, immobile liquid crystal panel 9 is in the side entering type liquid crystal module group backlight enclosing the two-stage light source that formation one is complete on frame assembly 8.
As Fig. 2, LED lamp bar 3 adopts blue LED lamp pearl, and this lamp pearl excites at electric current and issues raw opto-electronic conversion, generates single band visible blue; This lamp pearl, in the arrangement of pcb board Linear, forms blue line source.
As Fig. 3, light wave conversion film 7, under single band is blue-light excited, realizes the conversion between visible ray different-waveband, can generate the spectrum of RGB visible ray corresponding wavelength.
Above-mentioned backlight module luminous energy circulation way, blue LED lamp bar 3, under electric current drives, forms blue line source; This blue line source vertically injects light guide plate 5 end face, sees and carries out certain proportion total reflection and certain proportion reflection longitudinal propagation, penetrate, form blue light area source from light guide plate is non-with reflecting paper surface of contact in light guide plate 5 and reflecting paper 4.Light, through membrane combination 6, is gathered in main perspective by this area source further.Through the blue light area source of membrane combination 6, excitation light wave conversion film 7, generates red-green-blue.The white of this three basic mixture of colours is as the backlight of liquid crystal module.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
