The utility model proposes a kind of down straight aphototropism mode set, liquid crystal module and display devices, to solve traditional straight-down negative
The low problem of the reflectivity of white ink on backlight module pcb board.
Fig. 1 is please referred to, in the utility model embodiment, provides a kind of down straight aphototropism mode set comprising diffuser plate 10,
Backboard 20, the reflector plate 30 being set on backboard 20 and printed circuit board 40, printed circuit board 40 are set to backboard 20 and anti-
It penetrates between piece 30, down straight aphototropism mode set further includes light source 60 and lens 50, and reflector plate 30 offers through-hole 31, and light source 60 passes through
Through-hole 31 is mounted on printed circuit board 40, and lens 50 cover at outside light source 60, and lens 50 are mounted on reflector plate 30 and enclose
Set on 31 periphery of through-hole, the rays pass through lens 50 that light source 60 issues are projected to diffuser plate 10.
In this embodiment, printed circuit board 40 is set between backboard 20 and reflector plate 30, then by optical lens
50 are fixed on the light-emitting surface of reflector plate 30, the center on reflector plate 30 relative to lens 50 by the photosensitive glue attachment of UV
Through-hole 31 is opened up, light source 60 is passed through into through-hole 31 and is installed on printed circuit board 40, and lens 50 are mounted on reflector plate 30 simultaneously
It encloses set on the periphery of through-hole 31, reaches the interface of lens 50 Yu air from the luminous energy that light source 60 is emitted in this way, part luminous energy enters
50 inside of lens simultaneously injects on diffuser plate 10 from lens 50, and part luminous energy is reflected back.Traditional down straight aphototropism mode set
In, lens 50 are directly installed on printed circuit board 40,40 white ink of printed circuit board is covered in the peripheral region of light source 60,
Reflectivity only has 80% or so, when luminous energy arrival white ink interface, understands some and is absorbed loss, only 80% or so light
It can be reflected；And in the present invention, 60 peripheral region of light source covers reflector plate 30, and the reflectivity of reflector plate 30 is up to

Among the cavity that two crownings 51 are formed, the central axis of the central axis of lens 50, the central axis of light source 60 and through-hole 31
Line is overlapped.Since the vertical component at lens 50 towards 60 center of light source is most strong to the reflection of light, in order to make 50 center of lens
The light for locating reflection is less bright, inner concave 52 is arranged at the center of lens 50, and then improve the uniformity of the diverging of light source 60.
Wherein, light source 60 can be preferably LED light.
In addition, as shown in Fig. 2, having gap between the inner peripheral surface of through-hole 31 and the outer peripheral surface of light source 60, it is preferable that this reality
It applies in example, the gap between the inner peripheral surface of through-hole 31 and the outer peripheral surface of light source 60 is 0.2mm-2mm.Lens 50 are mounted on reflection
The upper surface of piece 30, reflector plate 30 opens through-hole 31 appropriate and avoids light source 60, and the size of through-hole 31 depends on the light of lens 50
Learn performance.Need reserved design gaps to guarantee smoothly to assemble between through-hole 31 and light source 60, general through-hole 31 and light source 60 it
Between gap be at least 0.2mm, and the gap of 60 periphery of light source is identical, further ensure that the uniformity that light source 60 reflects.
It, can be by the suitably amplification or the reflector plate 30 around light source 60 of the through-hole 31 on reflector plate 30 when showing as speck on light source 60
Upper increase through-hole 31；When showing as blackening on light source 60, the through-hole 31 on reflector plate 30 can suitably be reduced.Also, it reflects
Scattering particles is coated with away from the side of backboard 20 on piece 30.It is able to carry out diffusing reflection by scattering particles, the light that will be received
Line is broken up, so that light is more uniform, so that the light reflexed on diffuser plate 10 on reflector plate 30 is relatively uniform, avoids
There is lamp shadow phenomenon.
As shown in Figure 1, backboard 20 includes that bottom plate 22 and the side plate 21 around the setting of bottom plate 22, printed circuit board 40 are arranged
In on bottom plate 22, light source 60 is mounted on the side for deviating from bottom plate 22 on printed circuit board 40.In a preferred embodiment, backboard 20
Including bottom plate 22 and the side plate 21 being arranged around bottom plate 22, and bottom plate 22 and side plate 21 are around one open cavity of formation
80, the setting of diffuser plate 10 is encapsulated in open-mouth and by cavity 80, and lens 50, light source 60 and printed circuit board 40 are all placed in
In cavity 80, and printed circuit board 40 is set on bottom plate 22, and light source 60 is mounted on printed circuit board 40 away from bottom plate 22
On side.Reflector plate 30 includes the level side for being set to the reflector plate 30 of 20 inside of paranotum and being set on printed circuit board 40
To reflector plate 30, and the one end for being located at the reflector plate 30 of the inside of paranotum 20 is abutted with diffuser plate 10.Reflector plate 30 can incite somebody to action
The light received is broken up, and is transmissive to away a part of light, so that the low reflection characteristic that reflector plate 30 is utilized is reduced
It is incident to the reflection of diffuser plate 10 surrounding side wall light, liquid crystal display panel is can be avoided and the phenomenon that surrounding bright border occurs.Diffuser plate
10 effect is to allow the distribution of light is more uniform to make from the positive shadow that can't see reflection point.In addition, the downward back optical mode
Group further includes optical diaphragm 70, and optical diaphragm 70 is set to the side for deviating from light source 60 on diffuser plate 10.The light that light source 60 issues
Line can be just radiated on liquid crystal display panel after the diffusion of optical diaphragm 70.
