Abstract
The utility model discloses a super narrow frame shading of liquid crystal TV diffusion piece, including diffusion piece body, be provided with at diffusion piece lower limb and hide the light zone territory, hide the light zone territory and openly be the printing ink printing, the back is recess tangent each other, scribbles anti - light -absorbing coating in the recess. The utility model discloses a scribble on the anti -dazzling screen through the printing ink that the screen painting will be allocated in the front that hides the light zone territory, is provided with reflection of light recess simultaneously at the back, and reflection of light recess is three spherical shells of quartering, receives the light that comes from the light emitting source in it, forms the reflection passageway and go back to light reflection to light source emission department in the recess, and dual assurance hides not light leak of light zone territory, positive printing ink adopts grey, white, three kinds of UV printing ink allotments of black, can shield the light that comes from the light source, and the light -proofness is good, reaches that the diffusion piece after the black printing shields the light leak of light source department under the extremely narrow condition of backlight unit frame, and then makes the narrower design of backlight unit plastic frame to realize the super narrow frame design of TV set. Make the processing preparation convenient.
Description
Technical field
This utility model relates to television backlight die set, is specifically related to a kind of super-narrow frame for liquid crystal display television shading diffusion sheet.
Background technology
Present liquid crystal TV set (TFT-LCD) is mainly made up of LCDs, backlight module, electronic circuit and cabinet etc., and one of significant components that backlight module is liquid crystal TV set, because liquid crystal display screen itself is the most luminous, backlight module illuminating source is provided to show with the picture realizing television set.
Along with liquid crystal TV set universalness in family life, the consumer's more demand of proposition to television product, the low price of product, frivolous, the beautiful key factor becoming consumer's selection television set of profile.At present, ultra-narrow frame is television set profile developing direction, and television frame is the narrowest, and screen accounting is the highest, and profile is the most beautiful.But, because the plastic frame of backlight module surrounding demand one fixed width supports LCDs, and fix in backlight surrounding, continue to zoom out frame distance under structure particular case and can cause LED lamp bar in backlight module (light source) light leakage phenomena, this phenomenon causes TV image uneven even loss light efficiency energy, significantly limit the development of ultra-narrow frame television technology, therefore, accomplish that narrower frame has been technical bottleneck.
Utility model content
In place of the deficiencies in the prior art, this utility model combines the architectural characteristic of backlight module in liquid crystal TV set, black screen printable is carried out on the front of the diffusion sheet in backlight module, front is provided with reflective structure, reach backlight module frame the narrowest under conditions of diffusion sheet after black printing cover the light leak at light source, and then make the backlight module narrower design of plastic cement frame, thus realize the ultra-narrow frame design of television set.
A kind of super-narrow frame for liquid crystal display television shading diffusion sheet, including diffusion sheet body, is provided with lightproof area at diffusion sheet lower limb, and described lightproof area front is ink printing, and the back side is groove tangent to each other, scribbles reflecting coating in described groove.
Further, described ink is formed by Lycoperdon polymorphum Vitt, white, three kinds of UV ink formulation of black.
Further, described groove is 3/4ths hollow balls.
Further, by the way of screen printing, deployed black ink is printed on above diffusion sheet；The diffusion sheet printed is solidified by UV oven UV.Determining that mesh specification opens web plate mould, mesh specification 250-300 mesh includes meshed quantity per square inch.
Beneficial effect
Deployed ink is coated on brake sack by the front of lightproof area of the present utility model by screen painting, it is provided with reflective groove overleaf simultaneously, reflective groove is 3/4ths spherical shells, receive the light of self-emitting light source in it, in groove, form reflection channel reflect light back at light source transmitting, dual guarantee lightproof area not light leak；The ink in front uses Lycoperdon polymorphum Vitt, white, three kinds of UV ink formulation of black, the light from light source can be shielded, light-proofness is good, reach backlight module frame the narrowest under conditions of diffusion sheet after black printing cover the light leak at light source, and then make the backlight module narrower design of plastic cement frame, thus realize the ultra-narrow frame design of television set.Make processing and fabricating convenient.
Accompanying drawing explanation
Describe some specific embodiments of the present invention the most by way of example, and not by way of limitation in detail.Reference identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art, these accompanying drawings are not necessarily drawn to scale.
Fig. 1: this utility model overall structure schematic diagram.
Fig. 2: this utility model left view.
Fig. 3: this utility model A portion's enlarged drawing.
In accompanying drawing: diffusion sheet body-1；Lightproof area-2；Ink printed layer-3；Groove-4；Luminous source-5.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As Figure 1-3, a kind of super-narrow frame for liquid crystal display television shading diffusion sheet, including diffusion sheet body 1, is provided with lightproof area 2 at diffusion sheet body 1 lower limb, described lightproof area 2 front is ink printed layer 3, and described ink is formed by Lycoperdon polymorphum Vitt, white, three kinds of UV ink formulation of black；By the way of screen printing, deployed black ink is printed on above diffusion sheet body 1；The diffusion sheet body 1 printed is solidified by UV oven UV.Screen printing determines that mesh specification opens web plate mould, and mesh specification 250-300 mesh includes meshed quantity per square inch.The back side of diffusion sheet body 1 is groove 4 tangent to each other, and described groove 4 is 3/4ths hollow balls；Reflecting coating is scribbled, as it is shown on figure 3, groove 4 receives the light of self-emitting light source 5 in described groove 4, can disappear or return luminous source 5 by reflective several times, realize the shaded effect of ground floor, scribble ink printed layer 3 at groove 4 rear simultaneously, realize shading further.The double-deck good shading effect that ensures, processing and manufacturing simplicity.
Described above is not to restriction of the present utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should belong to protection domain of the present utility model.
