Description
Technical field
The utility model is related to display screen technology fields, and in particular to one kind exempting from light guide plate side entrance back module structure.
Background technology
Backlight module is one of the key part and component of panel of LCD, and function is well-off brightness and divides
The uniform light source of cloth, enables liquid crystal display normally to show image.Backlight module is mainly by light source, light guide plate, reflector plate, optics
The compositions such as diaphragm, backlight module can be divided into side entering type, straight-down negative, hollow type light-source structure, since down straight aphototropism mode set needs
More LED light source increases cost of manufacture, therefore is gradually eliminated；Currently, most commonly seen structure is side entrance back mould
Group is emitted to the light guiding points of light guide plate by LED point light source, and light guiding points dissipate incident light, to convert point light source to face light
Source.But since the cost of manufacture of light guide plate is higher, same uneconomical practicality.
Utility model content
In view of the above problems, the utility model provides, a kind of luminous efficiency is high, uniform light exempts from the light guide plate side entering type back of the body
Light modular structure.
To achieve the above object, the utility model solves by the following technical programs：
One kind exempting from light guide plate side entrance back module structure, including arc reflection backboard and the arc reflection backboard two
Hold the diffuser plate of connection, positioned at the light source of the arc reflection backboard and the diffuser plate intersection, the arc reflection backboard
The even surface of arc surface and a small radian including a big radian, the light source are located at the arc surface side.
Specifically, the diffuser plate be glass diffuser plate, including be close to arc reflection backboard side frosting, with
And the smooth surface far from arc reflection backboard side.
Specifically, the light source is made of multiple linearly aligned LED light.
Specifically, the arc reflection backboard includes glass back plate and the reflection positioned at the glass back plate medial surface
Piece.
Specifically, one side of the glass back plate far from the reflector plate is additionally provided with the heat-radiation coating bed of material.
The utility model has the beneficial effects that：
First, the utility model utilizes an arc reflection backboard and diffuser plate, you can converts point light source or linear light source
At area source as backlight module, traditional light guidance board type backlight module is compared, is avoided using expensive light guide plate,
It is cost-effective, it is worthy to be popularized；
Second, arc reflection backboard is divided into two parts, is the arc surface of big radian by close to sources part, far from light source part
For the even surface of small radian, light source is radiated on the reflector plate that radian differs, the emergent light uniform light after reflector plate reflects；
Third, diffuser plate are glass diffuser plate, are frosting on the inside of diffuser plate, the light after reflector plate emits reaches frosted
Face, frosting adjustable light, the refraction for making light generation different directions, reflection and scattering, to change the traveling road of light
Line realizes that incident light fully dissipates the effect that color generates optics diffusion with this；
4th, one side of the glass back plate far from reflector plate is additionally provided with the heat-radiation coating bed of material, enhances the heat dissipation of backlight module
Performance.
Description of the drawings
Fig. 1 is a kind of stereoscopic schematic diagram for exempting from light guide plate side entrance back module structure of the utility model.
Fig. 2 is the enlarged drawing of the utility model part A.
Fig. 3 is a kind of front view for exempting from light guide plate side entrance back module structure of the utility model.
Reference numeral is：Arc reflection backboard 1, arc surface 101, even surface 102, glass back plate 11, reflector plate 12, diffusion
Plate 2, light source 3.
Specific implementation mode
The utility model is described in further detail with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
As shown in Figs. 1-3：
One kind exempting from light guide plate side entrance back module structure, including arc reflection backboard 1 and 1 both ends of arc reflection backboard
The diffuser plate 2 of connection, positioned at the light source 3 of arc reflection backboard 1 and 2 intersection of diffuser plate, arc reflection backboard 1 includes a big arc
The even surface 102 of the arc surface 101 of degree and a small radian, light source 3 are located at 101 side of arc surface.
Preferably, diffuser plate 2 is glass diffuser plate, including is close to the frosting of 1 side of arc reflection backboard and separate
The smooth surface of 1 side of arc reflection backboard, light that light source 3 is sent out reach reflector plate 12, due to the reflector plate 12 by close to sources 3 be compared with
The arc surface 101 of big radian, the reflected light at this are concentrated mainly on 101 downside of arc surface, and part reflected light is under even surface 102
Side is projected, and due to the even surface 102 that the reflector plate 12 far from light source 3 is smaller radian, the reflected light at this is largely focused on
102 downside of even surface, by the Overlay of light, reflected light reaches uniform light when diffuser plate 2；After reflector plate 12 emits
After light reaches frosting, frosting adjustable light, the refraction for making light generation different directions, reflection and scattering, to change
The travelling route of light realizes that incident light fully dissipates the effect that color generates optics diffusion with this.
Preferably, light source 3 is made of multiple linearly aligned LED light.
Preferably, arc reflection backboard 1 includes glass back plate 11 and the reflector plate positioned at 11 medial surface of glass back plate
12, light source 3 is radiated on the reflector plate 12 that radian differs, the emergent light uniform light after the reflection of reflector plate 12.
Preferably, one side of the glass back plate 11 far from reflector plate 12 is additionally provided with the heat-radiation coating bed of material, enhances backlight module
Heat dissipation performance.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
