Embodiment 1
As shown in Fig. 2, providing a kind of down straight aphototropism mode set 100, including diffuser plate carrying in first embodiment of the invention
Platform 1, circuit board 2, diffuser plate 3, optical diaphragm 4 and birefringent diaphragm 5.In particular, being provided with multiple light on the circuit board 2
Source 6；The diffuser plate 3 is set on the diffuser plate plummer 1；The optical diaphragm 4 is set on the diffuser plate 3；It is described double
It reflects diaphragm 5 and is set to 2 top of circuit board；The light that wherein light source 6 projects is after the birefringent diaphragm 5 reflects
It is propagated to the direction far from the light source 6.
In the first embodiment, the birefringent diaphragm 5 is set to surface of the diffuser plate 3 towards 6 side of light source
Edge.The birefringent diaphragm 5 reflects the light that the light source 6 projects, and by the light after refraction to institute
It propagates at the edge for stating diffuser plate plummer 1.It is possible thereby to be obviously improved the defect of quadrangle shadow, the display of the light of corner is improved
Brightness makes entire display area show that more evenly, display effect is more preferable.
As shown in figure 3, in the first embodiment, the light source 6 is distributed on the circuit board 2 in array.Shown light
Source 6 is preferably Organic Light Emitting Diode (LED).Specifically, shown light source 6 can be set more in the four corners for being located at the circuit board 2
It sets several, prevents shown 6 distance value of light source bigger than normal for providing enough light, cause the light of normal luminous that can not be sufficient to
Up to the corner location of display area, causing quadrangle has shade, secretly outlines existing bad phenomenon.
In the first embodiment, the birefringent diaphragm 5 can be one of rectangle, rectangular-ambulatory-plane, triangle or a variety of.
As long as meeting the light that the light source 6 projects to propagate after the birefringent diaphragm 5 reflects to the direction far from the light source 6
Belong to the scope of the present invention.When the birefringent diaphragm 5 is in rectangle, the birefringent diaphragm 5 can be with the diffusion
3 geomery of plate is adapted, or and it is multiple, it is set to the side edge or edge of the diffuser plate 3；Further to save
About material cost and integrated setting, the birefringent diaphragm 5 are in rectangular-ambulatory-plane, i.e., hollow structure；To further save material
Cost, the birefringent diaphragm 5 can be triangular in shape, is set to the edge of the diffuser plate 3.
As shown in figure 4, the present invention preferably rectangular triangle of the birefringent diaphragm 5, is set to the side of the diffuser plate 3
At angle, the birefringent diaphragm 5 is attached at the surface towards 6 side of light source of the diffuser plate 3.If setting the diffuser plate
The length of 3 long side be M, if the length of the short side of the diffuser plate 3 be H, the rectangular triangle of the birefringent diaphragm 5 it is straight
Arm of angle side length is respectively A and B, and 0 < A < M/2,0 < B < H/2 is arranged.That is, the right angle side length of the birefringent diaphragm 5 is less than correspondence
The half of 3 side length of diffuser plate.
The birefringent schematic diagram of the birefringent diaphragm 5 as shown in figure 5, interface a and b are the upper and lower surface of birefringent film,
After light beam (indicated by an arrow in Fig. 5) is incident on birefringent film, birefringent phenomenon occurs, generates two beam polarised lights: ordinary
Light (o light) follows the law of refraction, and extraordinary ray (e light) does not follow the law of refraction, refraction the wave vector Ko and Ko of o light ' it indicates,
Refraction the wave vector Ke and Ke of e light ' is indicated.As it can be seen that the deflection distance that extraordinary ray (e light) increases light, more fixed than following refraction
The refractive index of the ordinary light (o light) of rule is big.It is worth noting that the birefringent diaphragm 5 is the prior art, it is more detailed former
This will not be repeated here for reason.
In the first embodiment, the ranges of indices of refraction of the diffuser plate 3 is 1.48-1.60.The diffuser plate 3 can be
Bright material is also possible to the material for having certain mist degree: such as glass, quartz, PMMA, MS, PS；The plate of the diffuser plate 3 can
It, can not also printing net-point with printing net-point.
Further, it is the defect for improving quadrangle shadow to greatest extent, improves the display brightness of the light of corner, make whole
A display area shows that more evenly, display effect is more preferable, and realizes narrow frame design, as shown in fig. 6, in the first embodiment,
The diffuser plate plummer 1 is in cuboid, is surrounded by end to end surround of four diffuser plate plummer side walls 11, the side wall
Edge thickness be less than the side wall interior thickness；The two neighboring side wall connects to forming corner on the inside of V-arrangement.
As shown in fig. 6,1 tapering width of diffuser plate plummer (top view) near straight-down negative quadrangle, setting are as follows:
0<P<M/2；0 < Q < H/2, described remaining width of diffuser plate plummer 1 are constant, in order to carry the diffuser plate 3.
As shown in Fig. 2, being sectional view of the diffuser plate plummer 1 at A-A, that is, it is located at the diffuser plate plummer 1
Middle position；As shown in fig. 7, being sectional view of the diffuser plate plummer 1 at B-B, that is, it is located at the diffuser plate and carries
The marginal position of platform 1；The diffuser plate plummer 1 includes lateral reflection structure, near 100 4 jiaos of the down straight aphototropism mode set
1 tapering width of diffuser plate plummer, so that influencing the lateral reflection structure slope of the diffuser plate plummer 1 also needs
Synchronize change.This purpose is not only to have guaranteed that the diffuser plate plummer 1 for carrying the diffuser plate 3 had certain width, but also can
To gradually taper up to form corner on the inside of V-arrangement in 1 four edges of the diffuser plate plummer, in the defect for improving quadrangle shadow
While further realize narrow frame design.
