Description
[technical field]
The present invention relates to a kind of backlight module, particularly to a kind of curved surface LCD backlight module.
[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 that it is the normal show image of energy, current backlight module can not be with light source due to the one or both sides of light guide plate
Compact siro spinning technology, has black vaginal discharge and produces, reduce the luminescent quality of backlight module when luminescence.
[summary of the invention]
A kind of curved surface LCD backlight module of offer is provided, due to the light source of light guide plate both sides, can
To avoid, when luminescence, black vaginal discharge occurs, enhance the luminescent quality of backlight module, due to blooming piece, can be anti-with uniform light guide plate
The light penetrated, in order to staff front is observed, and can effectively solve the problem in background technology.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of curved surface LCD backlight module, including back frame, light source, light guide plate, diffusion barrier, blooming piece and brightness enhancement film, institute
Stating back frame and be placed in backlight module bottom, described backlight module is from top to bottom followed successively by described brightness enhancement film, described diffusion barrier, described light
Learn diaphragm and described light guide plate, two light sources and the both sides compact siro spinning technology of described light guide plate, described light guide plate is provided with multiple
Backlight frame, described frame is funnel-form, and funnel bottom is inclined-plane, and funnel front end is parallel surface, and described backlight module is overall
Form a curved surface.
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, there is advantages that due to the light source of light guide plate both sides, can avoid
Time luminous, black vaginal discharge occurs, enhance the luminescent quality of backlight module, due to blooming piece, can be with the light of uniform light guide plate reflection
Line, in order to staff front is observed, due to light guide plate, can guide the scattering direction of light source, improve brightness, and guarantee bright
The uniformity of degree, owing to 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, is entangled by light
Just to parastate, then retrained by front end parallel surface, thus be greatly reduced backlight scattering, it is to avoid backlight interferes feelings
The generation of condition.
[accompanying drawing explanation]
Fig. 1 is the overall structure schematic diagram of the present invention.
In figure: 1, back frame；2, light source；3, light guide plate；4, diffusion barrier；5, blooming piece；6, brightness enhancement film.
[detailed description of the invention]
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
As it is shown in figure 1, a kind of curved surface LCD backlight module, including back frame 1, light source 2, light guide plate 3, diffusion barrier 4, blooming
Sheet 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 and the both sides compact siro spinning technology of described light guide plate 3,
Being provided with multiple backlight frame on described light guide plate 3, described frame is funnel-form, and funnel bottom is inclined-plane, and funnel front end is
Parallel surface, described backlight module is integrally formed a curved 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 in luminescence
Time black vaginal discharge occurs, enhance the luminescent quality of backlight module, due to blooming piece 5, can with the light of uniform light guide plate 3 reflection,
So that staff front is observed, 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, owing to 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, outside without injecting to light guide plate 3.Light, by forming an inclined-plane, is corrected to flat by present configuration
Row state, then retrained by front end parallel surface, thus it is greatly reduced backlight scattering, it is to avoid 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 is by described wiring board and described light guide plate
The side of 3 is connected.
Wherein, described light guide plate 3 is made up of acrylic plastics.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
