Abstract
The invention discloses a liquid crystal display screen backlight structure production method. A plurality of backlight side frames are mounted on a light guide plate; each side frame is in a funnel shape; the bottom of the funnel is provided with a slope; the front end of the funnel is provided with a parallel surface; two sides of the light guide plate are respectively connected with a light source; a layer of optical film sheet is applied over the light guide plate; a layer of diffusion film is adhered over the optical film sheet; a brightening film is adhered over the diffusion film; a backlight module set is formed thereby; and at last, a back frame is installed on the bottom end of the backlight module set. With the light sources on the two sides of the light guide plate, black strips during luminescence can be avoided, so luminescent quality of the backlight module set can be enhanced; and with the optical film sheet, light rays reflected by the light guide plate can be evened, so workers can observe in front.
Description
【Technical field】
The present invention relates to a kind of backlight module, particularly to a kind of LCD screen backlight structure production method.
【Background technology】
Backlight module is one of key part and component of panel of LCD.Function is well-off brightness and distribution
Uniform light source so as to can normal show image, current backlight module can not be with light source due to the one or both sides of light guide plate
Closely connect, have black-tape when luminous and produce, reduce the luminescent quality of backlight module.
【Content of the invention】
Present invention is primarily targeted at providing a kind of LCD screen backlight structure production method, due to light guide plate both sides
Light source, can avoid that black-tape occurs when luminous, enhance the luminescent quality of backlight module, due to blooming piece, Ke Yijun
The light of even light guide plate reflection, observes in order to staff front, can be with the problem in effectively solving background technology.
For achieving the above object, the technical scheme that the present invention takes is：
A kind of LCD screen backlight structure production method, its scheme is as follows：
Multiple backlight frames will be arranged on light guide plate, described frame is in funnel-form, funnel bottom is inclined-plane, funnel front end
For parallel surface；
Light guide plate both sides are connected with a light source respectively, paste one layer of blooming piece above light guide plate, in blooming piece
Top one layer of diffusion barrier of patch, pastes one layer of brightness enhancement film above diffusion barrier, so makes backlight module；
Finally again back frame is installed in backlight module bottom.
Further, described light source is made up of LED and wiring board, and described LED is led with described by described wiring board
Tabula rasa is connected.
Further, described light guide plate is made up of acrylic plastics.
Compared with prior art, the present invention has the advantages that：Due to the light source of light guide plate both sides, can avoid
Black-tape occurs when luminous, enhances the luminescent quality of backlight module, due to blooming piece, can be with the light of uniform light guide plate reflection
Line, observes in order to staff front, due to light guide plate, can guide the scattering direction of light source, improve brightness, and guarantee bright
The uniformity of degree, because light guide plate is made up of acrylic plastics, smooth surface is smooth, and internal light can be advised on its flat surface
Total reflection then, without injecting to outside light guide plate, present configuration forms an inclined-plane by backlight frame, and light is entangled
Just to parastate, then row constraint is entered by front end parallel surface, thus greatly reducing backlight scattering, it is to avoid backlight interferes feelings
The generation of condition.
【Brief description】
The product structure schematic diagram that Fig. 1 produces for the inventive method.
In figure：1st, back frame；2nd, light source；3rd, light guide plate；4th, diffusion barrier；5th, blooming piece；6th, brightness enhancement film.
【Specific embodiment】
Technological means, creation characteristic, reached purpose and effect for making the present invention realize are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
As shown in figure 1, the product that the inventive method produces, including back frame 1, light source 2, light guide plate 3, diffusion barrier 4, blooming
Piece 5 and brightness enhancement film 6, described back frame 1 is placed in backlight module bottom, described backlight module be from top to bottom followed successively by described brightness enhancement film 6,
Described diffusion barrier 4, described blooming piece 5 and described light guide plate 3, two light sources 2 are closely connected with the both sides of described light guide plate 3,
Multiple backlight frames are provided with described light guide plate 3, described frame is in funnel-form, funnel bottom is inclined-plane, and funnel front end is
Parallel surface.
The present invention can strengthen the backlight module of luminescent quality, due to the light source 2 of light guide plate 3 both sides, can avoid luminous
When black-tape occurs, enhance the luminescent quality of backlight module, due to blooming piece 5, can with the light of uniform light guide plate 3 reflection,
Observe in order to staff front, due to light guide plate 3, the scattering direction of light source 2 can be guided, improve brightness, and guarantee bright
The uniformity of degree, because light guide plate 3 is made up of acrylic plastics, smooth surface is smooth, and internal light can be on its flat surface
The total reflection of rule, without injecting to outside light guide plate 3.Present configuration passes through to form an inclined-plane, and light is corrected to flat
Row state, then enter row constraint by front end parallel surface, thus greatly reduce backlight scattering, it is to avoid the sending out of the mutual disturbed condition of backlight
Raw.
Wherein, described light source 2 is made up of LED and wiring board, and described LED passes through described wiring board and described light guide plate
3 side is connected.
Wherein, described light guide plate 3 is made up of acrylic plastics.
The inventive method is as follows：
Multiple backlight frames will be arranged on light guide plate, described frame is in funnel-form, funnel bottom is inclined-plane, funnel front end
For parallel surface.Light guide plate both sides are connected with a light source respectively, paste one layer of blooming piece above light guide plate, in blooming piece
Top one layer of diffusion barrier of patch, pastes one layer of brightness enhancement film above diffusion barrier, so makes backlight module.Finally again by backlight module bottom
Back frame is installed at end.
General principle and principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
, it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally for personnel
