the interface that glass, transparent membrane etc. contact with air is 4% left and right to reflection of light rate
therefore R1v ≈ 4%, R2v ≈ 4%
lCDs, because inner structure has reflection, records LCDs surface generalization reflectivity R3v ≈ 5%
with the liquid crystal display of touch-screen, in the time having air layer between touch-screen and LCDs, it adds up to reflectivity Rv=R1v+R2v+R3v ≈ 13%
catoptrical intensity (brightness) R=A*Rv
when environmental light brightness is at 2000Lux time, reflected light brightness R reaches 260, and the brightness T2 of display is in 250 left and right conventionally, therefore Ambient (as window, light) can disturb normal evaluation equipment to show,
and if out of doors, environmental light brightness reaches 10000Lux especially, reflected light brightness R reaches 1300, and the image on display screen does not see at all.

a is the incident light that shines display
t1 is that incident light A sees through the printing opacity after touch-screen module
r1 is the reflected light of incident light A in glass cover plate surfaces, and the reflectivity of this surface correspondence is R1v
r2 is the reflected light of incident light A at touch-screen inside surface, and the reflectivity of this surface correspondence is R2v
r3 is the reflected light of incident light A at liquid crystal display screen surfaces, and the reflectivity of this surface correspondence is R3v
t2 is the light that light transmission touch-screen descendant eye that display screen sends is seen
under the effect of antireflection coating, R1v≤0.4%, presses R1v=0.4% here and calculates
R2v≈4%，R3v≈5%
and through the filtration of the second polaroid 6, the intensity of T1 reduces half
T1=A*1/2
r2 reflects away the filtration through second polaroid 6 again
same R3 also reduces by a half intensity through the filtration of the second polaroid 6
R=A*R1v+T1*R2v*1/2+T1*R3v*1/2=?A*(R1v+?R2v*1/4+R3v*1/4)
and R=A*Rv
be Rv=R1v+ R2v*1/4+R3v*1/4 ≈ 0.4%+4%*1/4+5%*1/4 ≈ 2.65%
now
when environmental light brightness is at 2000Lux time, reflected light brightness R only 53, the brightness of display is in 250 left and right, therefore the impact that Ambient (as window, light) shows evaluation equipment is very little conventionally; And if out of doors, environmental light brightness has 10000Lux, now reflected light brightness R has been reduced to about 265Lux, compares originally 1300, has reduced closely 80%, can more clearly watch out of doors screen content.
