Abstract
The utility model relates to the field of the electric light source, especially a color screen LED backlight source, which comprises a diffusion film, an LED lamp, a light guide board, a glue frame and a reflecting sheet, a chip coated with fluorescent powders is arranged in the LED lamp, an upper light increasing film and a lower light increasing film of the black and white double-face glues are covered on the diffusion film from top to bottom in turn. An FPC flexible circuit board pasted with the LED lamp is pasted on the top of the light guide board by the FPC double-face glues. fluorescent powders with various colors which are mixed with an AB glue are dropped on the chips with various colors by a glue dropping machine, under the action of the current, the LED lamp can excite various colors to present the beautiful light rays.
Description
Technical field
The utility model relates to the electric light source field, especially a kind of color screen LED-backlit source.
Background technology
Present backlight mainly contains three types of EL, CCFL and LED, wherein the LED-backlit plate has the advantage of life-span length, low consumption, high brightness, high efficiency and environmental protection, fast development along with the LED technology, LED replaces EL and CCFL light source gradually, become the main stream light sources of backlight development, but the brightness of existing LED-backlit plate is very low, and color is also more single.
The utility model content
Low in order to overcome the brightness of existing LED-backlit plate, the deficiency that color is single, the utility model provides a kind of color screen LED-backlit source.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of color screen LED-backlit source, comprise diffusion barrier, LED lamp, LGP, glue frame and reflector plate, the chip that scribbles fluorescent material is set in the LED lamp, is covered with bright enhancement film and following bright enhancement film on the black and white double faced adhesive tape on the diffusion barrier from top to bottom successively.
The FPC flexible circuit board that is stained with the LED lamp sticks on the LGP top by the FPC double faced adhesive tape.
The beneficial effects of the utility model are, by will with the versicolor fluorescent material of AB glue allotment with point gum machine point on versicolor chip, the LED lamp inspires shades of colour under the effect of electric current, present gorgeous radiance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model.
1. black and white double faced adhesive tapes are 2. gone up bright enhancement film among the figure, 3. descend bright enhancement film, 4. diffusion barrier, 5.FPC flexible circuit board, 6.LED lamp, 7. LGP, 8. glue frame, 9. reflector plate, 10.FPC double faced adhesive tape.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1 is schematic diagram of the present utility model, a kind of color screen LED-backlit source, comprise diffusion barrier 4, LED lamp 6, LGP 7, glue frame 8 and reflector plate 9, the chips that scribble fluorescent material are set in the LED lamp 6, be covered with bright enhancement film on the black and white double faced adhesive tape 1,2 and following bright enhancement film 3 on the diffusion barrier 4 from top to bottom successively.The FPC flexible circuit board 5 that is stained with LED lamp 6 sticks on LGP 7 tops by FPC double faced adhesive tape 10.
By will with the versicolor fluorescent material of AB glue allotment with point gum machine point on versicolor chip, the LED lamp inspires shades of colour under the effect of electric current, present gorgeous radiance, be covered with bright enhancement film 2 and following bright enhancement film 3 on the diffusion barrier 4, improve light transmittance, strengthened the brightness of display screen.Black and white double faced adhesive tape 1 is bonded at above the glue frame 8, plays the effect of shading when fixing each parts again, avoids light scattering excessive.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
