Abstract
The utility model relates to the field of backlight sources, in particular to an LED backlight source with the double-surface light-emitting function, which can uniformly emit light from double surfaces, wherein the strength of the light emitted from the double surfaces can be adjusted according to requirements, thereby greatly broadening the using range of the LED backlight source; and two backlight sources are combined into one backlight source for design and use, so that the consumption of raw materials and the consumption of energy are reduced to one half. The structure improvement of the LED backlight source enables the thickness of an ultrathin double-screen LCD (liquid crystal display) to be very small, and the thickness of the backlight source thereof is reduced in comparison with the original double light guide plate backlight source, so that the wider space for the structural design and the appearance design of the double-screen LCD is provided.
Description
[technical field]
The utility model relates to the backlight field, specifically refers to a kind of LED-backlit source with double-side function.
[background technology]
Present existing luminous backlight is always seen the strong or weak shade that reverse side is windowed and caused when providing ambient light illumination for a slice liquid crystal LCD display, because the develop rapidly of current Display Technique, the double screen technique that secondary screen is opened fenestella has obtained using widely, such as: field of mobile communication, multimedia audio receiver, toy etc. all press for the double-side backlight that power consumption is little, luminous evenly, the little particularly gauge of size is little.
[utility model content]
The utility model purpose is to solve the above problems, and a kind of LED-backlit source with double-side function of reasonable in design, dependable performance is provided.
A kind of LED-backlit source with double-side function, comprise the glue frame of LED illuminator, LGP, lightguide plate fixing, the following diffusion barrier that is positioned at the LGP bottom surface and following bright enhancement film, the last diffusion barrier that is positioned at the LGP upper surface and last bright enhancement film, described LGP lower surface is the round point shape or the linear decorative pattern of pit or projection, pit or the projection decorative pattern be regularly arranged into the point-like array, the upper surface of LGP be flour milling, minute surface or discharge face one of them.
Preferably, the arranging rule of the pit on described LGP surface or projection is: pit or spacing projection between near more apart from the LED illuminator are big more, and pit or spacing projection between far away more apart from the LED illuminator are more little.
Described LGP light-conductive rate is greater than 80%, and described LGP is embedded in the glue frame.
The utility model can two-sided uniformly light-emitting, and the intensity of double-side can adjust on demand, thereby has widened its scope of application greatly; Because two backlights are combined into a backlight carries out design and use, therefore the raw-material consumption of minimizing at double and the consumption of the energy, the utility model improvement structurally can make the gauge of ultrathin double screen liquid crystal LCD display reach very little, its backlight gauge is partly compared with former pair of LGP backlight, can reduce thickness, thereby provide more wide space for structural design, the appearance design of double screen liquid crystal LCD display.

[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in ginseng Fig. 1,2 and 3, the utlity model has the LED-backlit source of double-side function, comprise the glue frame 7 of LED illuminator 1, LGP 2, lightguide plate fixing, the following diffusion barrier 5 that is positioned at LGP 2 bottom surfaces and following bright enhancement film 6 and the last diffusion barrier 3 and the last bright enhancement film 4 that are positioned at LGP 2 upper surfaces, wherein said backlight is single LGP, described LGP 2 lower surfaces are round point shape or linear decorative patterns of pit or projection, the round point shape of pit or projection is arranged in array-like, and the upper surface of LGP is flour milling, minute surface or discharge face.
According to the utility model of said structure, the arranging rule of the pit on described LGP 2 surfaces or projection is: apart near more its pit of light source or projection is just more little or spacing is big more, apart from light source its pit far away more or projection is just big more or spacing is more little.
According to the utility model of said structure, described LED illuminator 1 its LED quantity can be that simple grain also can be many.
According to the utility model of said structure, described LGP 2 light-conductive rates are greater than 80%, and described single LGP 2 is embedded in the glue frame 7.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
