It projects in 12 front of plate.By various densitys, light guiding points not of uniform size, 12 uniformly light-emitting of light guide plate can be made.The utility model
The double-sided screen 10 that 2D/3D high definition ultra high-definition ultrathin double-face brightness based on LCD/OLED/QLED can be set is by designing light guide plate
12 the first face 121 and the second face 122 form different types of first face light guiding points 121a and the second face light guiding points 122a, to
Realize that two sides exports the light of different brightness.
LED light source 11 is after the entrance of the light incident side of light guide plate 12, the refraction up and down in light guide plate 12 in the x-direction, until x
Direction end side encounters reflectance coating and returns again to, can be to when encountering the first face light guiding points 121a or the second face light guiding points 122a
The all angles scattering light of first face light guiding points 121a or the second face light guiding points 122a, therefore when light is along the first face of light guide plate 12
121 when encountering the first face light guiding points 121a, and a part of light is scattered out from the first face 121 upwards, and a part encounters downwards again
Second face, 122 light guiding points bounce back is scattered out from the first face 121 again, when light encounters along the second face 122 of light guide plate 12
When two face light guiding points 122a, a part of light is scattered out from the second face 122 downwards, and a part encounters the first face leaded light again upwards
Point 121a bounce backs are again scattered out from the second face 122.
In the present embodiment, by taking 32 cun of double-sided screen 10 as an example, the size of light guide plate 12 is 711mm*207mm, thickness
2.5mm.I.e. the area in the first face 121 and the second face 122 is all 0.711*0.207=0.147177m2, i.e. SA(x) and SB(x)
Total area is all 0.147177m2。
Incident side size X is 700, using 72 7020 twin crystal lamp beads, the nominal light flux 80lm of single lamp bead, light emitting anger
Degree is 120 degree, i.e., initial total light flux is 5760lm, initial beam intensity 1920cd, wherein cd is luminous intensity unit, indicates that light exists
Light emitted flux magnitude in a certain specific direction angle, formula are cd=Lm/ Ω, and wherein Ω is solid angle, and unit is surface of sphere
(sr)。
Lamp bead is 0.2mm apart from light guide plate 12, due to distance and light emitting angle, into can lose one when light guide plate 12
Point, it is calculated by 15%, then the initial beam intensity for entering light guide plate 12 is 1920* (1-15%)=1632cd, then theoretically initial bright
Spend L0=1632/0.1471777=11088cd/m2Namely L0Original intensity 11088nit, wherein nit=cd/m2, L0For light
Source 11 enters the original intensity of light guide plate 12.
It is assumed that when free of losses, the initial light in the first face 121 and the second face 122 should be the same, i.e. LA(x)=
11088/2=5544nit, LB(x)=11088/2=5544nit.
Since the diameter and density degree of the first face light guiding points 121a and the second face light guiding points 122a are different, i.e. FA(x)
=SA(x)/dA 2, FB(x)=SB(x)/dB 2。
It is assumed that FA(x) it is 0.9, FB(x) it is 0.6, due to the flatness of light guide plate 12, influences the first face 121 in X direction
Efficiency is theoretically completely smooth, it should be 100%, it is assumed that the first face 121 is identical as the flatness in the second face 122, it is assumed that KA1
And KB1All it is 0.9, due to the thickness effect light-out effect of light guide plate 12, by taking thickness 2.5mm as an example, it is assumed that KAAnd KBAll it is
0.85。
PAB=KB1*LA(x)*(1-FB(x))=0.9*5544* (1-0.6)=1995.84；
PAA=KA1*LA(x)*FA(x)=0.9*5544*0.9=4490.64；
The first brightness P in the first face 121A=KB*PAB+KA*PAAA=0.85*1995.84+0.85*4490.64=
5513.508nit；
PBA=KA1*LB(x)*(1-FA(x))=0.9*5544* (1-0.9)=498.96；
PBB=KB1*LB(x)*FB(x)=0.9*5544*0.6=2993.76；
The second brightness P in the second face 122B=KA*PBA+KB*PBB=0.85*498.96+0.85*2993.76=
2968.642nit；
Then 121 average brightness of the first face is 5513.508nit, and the average brightness in the second face 122 is 2968.642nit.
Using this mode, then the first face 121 of light guide plate 12 and the average brightness that the second face 122 is different are realized, then pass through
The first liquid-crystalline glasses 15 and the second liquid-crystalline glasses 16 (one are loaded onto in the gain for crossing the first optical diaphragm 17 and the second optical diaphragm 18
As transmitance 4% -8%) after, the brightness that the first liquid-crystalline glasses 15 at the front finally can be realized is more than 1000nit, lean on room
The brightness of the second interior liquid-crystalline glasses 16 is 300-500nit.
It such as needs to finely tune, then mainly adjusts the density degree of the first face light guiding points 121a and the second face light guiding points 122a.
After being selected due to the size of double-sided screen 10, then such as 32 cun of display areas i.e. 700 are grown, then incident side length is also essentially 700mm long.
After length determines, 7020 lamp beads (i.e. long 7mm, wide 2mm) are such as selected, then lamp bead number is also determined as 72 substantially.Only twin crystal
Or two kinds of monocrystalline is optional, according to product power requirement, then the Current Voltage of lamp bead is also substantially determining.It is guide-lighting using 7020 lamp beads
The thickness of plate 12 also determines that generally only optional 2.5mm or 3mm does not push up lamp bead and maximum to ensure that light guide plate 12 is heated substantially
Efficiency, general lamp bead to the gap of the incident side of light guide plate 12 are 0.2-0.5mm.According to product size, then the length of light guide plate 12
Wide size also determines that area also determines.
