With reference to figure 1, Fig. 1 is the structural drawing of a kind of pad pasting for device screen that the embodiment of the present invention provides, described pad pasting comprises upper surface and lower surface, described lower surface is the one side being close to described device screen, wherein, described upper surface and lower surface all uniform fold have Rhizoma Sparganii column mirror grating, the Rhizoma Sparganii column mirror grating of described upper surface is horizontally made up of successively the isosceles triangle that multiple size and shape is all identical, and the Rhizoma Sparganii column mirror grating of described lower surface is made up of the isosceles triangle that multiple size and shape is all identical; The base angle of the isosceles triangle of described upper surface is y, and the base angle of the isosceles triangle of described lower surface is x, and described x is not equal to described y.
The Refractive Index of Material of described pad pasting is r, the material thickness of described pad pasting is thick, sighting distance see=thick*tan (a – the b)/tan (Θ) of described pad pasting, wherein a=x, b=arcsin (sin (x)/r), c=y-x+b, d=arcsin (r*sin (c)), Θ=y – d;
X is larger, and see is larger, and x is less than or equal to 45 °;
Thick is larger, and see is larger;
R is larger, and see is larger.
The sighting distance increment rate of described pad pasting is see/m, described m for eye distance from.
Concrete, be a kind of method schematic diagram calculating triangular prism mirror sighting distance that the embodiment of the present invention provides with reference to figure 2, Fig. 2.As shown in Figure 2, obtain following equation according to basic geometric reasoning, all angles are all in units of angle below:
1)a＝x
2)r＝sin(a)/sin(b)＝sin(d)/sin(c)
3)y＝d+Θ
4)(d-c)+Θ+(90–x)+90+b＝180
5)thick*tan(a–b)＝see*tan(Θ)
Arrange above-mentioned equation and can obtain following formula:
Formula 1:a=x;
Formula 2:b=arcsin (sin (x)/r);
Formula 3:c=y – x+b;
Formula 4:d=arcsin (r*sin (c));
Formula 5: Θ=y – d;
Formula 6:see=thick*tan (a – b)/tan (Θ).
Following constraint condition can be released to formula 6 by formula 1:
This grating must avoid situation about being totally reflected to occur as far as possible, and the normalized form from being totally reflected: sin (angle of total reflection)=1/r, b and c can not be greater than arcsin (1/r);
Meanwhile, Θ is that positive and negative is all fine, but in order to convenience of calculation, result of calculation given below and conclusion all suppose that Θ is positive number.
Also need the interpupillary distance s of consideration user in actual use, use eye distance from m, following useful conclusion can be drawn from formula 1 to formula 6:
1) x is larger, and see is larger, and effect is better, but x does not advise being greater than 45 degree, because when being greater than 45 degree, the refract light of the lower surface in device may be stopped by the grating closed on, and causes final image distortion, and recommended value is 45 degree;
2) thick is larger, and see is larger, and effect is better;
3) r is larger, and see is larger, and effect is better.
Suppose that user of the present invention is children, its interpupillary distance s=5.5cm, screen is mobile phone screen, and custom eye distance is from m=25cm.Continue to use the variable of Fig. 2, suppose r=2.5, x=50, thick=1cm.Above-mentioned parameter being substituted into computing formula of the present invention, by regulating the value of y, formula below being set up: s/2=(m+see) * tan (Θ), this formula makes see large as far as possible.As calculated, as angle y ≈ 47.5 degree, equation is set up, now, and r=2.5, a=50.0, b=17.84, c=15.34, d=41.42, x=50.0, Θ=6.08, the angle of total reflection=23.58, thick=1.0, see=5.9.Obviously this result of calculation meets constraint condition of the present invention, and namely in the present case, sighting distance see adds 5.9cm, sighting distance increment rate see/m=23.6%.
When actual production, increase r and x and can reduce thick, trade-off process has manufacturer to hold, and does not inquire in the present embodiment.
Suppose that user of the present invention is adult, its interpupillary distance s=6cm, screen is TV screen, with eye distance from m=200cm, supposes r=2.5, x=50, thick=1cm.The method using the embodiment of the present invention to provide calculates, and can obtain following result: as angle y ≈ 49.7 degree, r=2.5, a=50.0, b=17.84, c=17.54, d=48.90, x=50.0, Θ=0.8, the angle of total reflection=23.58, thick=1.0, see=45.7, namely additionally increases the sighting distance of 45.7cm, and sighting distance increment rate is see/m=22.85%.
Suppose that user of the present invention is adult, its interpupillary distance s=6cm, screen is mobile phone screen, and that wishes control user uses eye distance from m=35cm.Suppose r=1.5, x=45, thick=0.1cm.Use the method for the embodiment of the present invention to calculate, following result can be obtained: r=1.5, a=45.0, b=28.13, c=21.63, d=33.54, x=45.0, Θ=4.94, the angle of total reflection=41.81, thick=0.1, see=0.35, namely, when parameter of the present invention meets above result of calculation, the viewing ratio that can control screen is m=35cm.
As the effect schematic diagram that Fig. 3, Fig. 3 are a kind of pad pastings for device screen that the embodiment of the present invention provides.Grating upper surface and lower surface are isosceles triangle, and upper surface isosceles triangular hill angle is y, and lower surface isosceles triangular hill angle is that x, x are not equal to y.Because the protruding angle of upper and lower surface x with y is not identical, thus the incident ray of grating and emergent ray not parallel, there is differential seat angle, as x ﹥ y, the light sent from O1 point only can enter the left eye of people, and right eye be can't see, in like manner, right eye can see O2 point but left eye be can't see; As x ﹤ y, the light sent from O1 point only can enter the right eye of people, and left eye be can't see, and in like manner, left eye can see O2 point but right eye be can't see.
Concrete, as shown in Figure 3, suppose to launch laser from O1 normal to screen, first through the refraction of lower surface, because the refractive index of any object is all large than air, therefore incident light offset by a left side after entering material, and a in Fig. 3 is necessarily greater than b, and deviation angle is left a-b, the light of laser continues to propagate, when described light transmition reflects again to during the upper surface of grating, this refraction is that light enters into air from grating, and therefore d is necessarily greater than c.We extend emergent light, through the calculating of triangle theorem several times, can show that Θ=y – d is necessarily greater than 0, namely this vertical light sent from O1 point inherently offsets left after the device of such as Fig. 3, distance is had between two eyes of people, average out to 6 centimetres, light offsets left, is observed by left eye.
In like manner, if the vertical light that O1 point sends moves to left avertence after the device of Fig. 3, the vertical light that then O2 point sends moves to right avertence after the device of Fig. 3, because be isosceles triangle, so the image being equivalent to half can allow left eye see, the image of half is seen by right eye, preset d1 and d2 and be less than 0.5 millimeter, as shown in Figure 1, d1 is the base of upper surface isosceles triangle, d2 is the base of lower surface isosceles triangle, this micro-scale people cannot differentiate, so we feel that left eye sees all images, right eye also sees all images, and the position of this image is not at O point, but at O ' point, be equivalent to focus vision to farther position.
In like manner analogize, in fact the light that pointolite sends diffuses to from all directions, for Fig. 3, suppose that incident ray is originally to left avertence, so emergent light is then partial to more left position, if incident ray is originally to right avertence, so emergent light is then partial to righter position, from distribution, the light injecting left eye is more than right eye, namely left eye also can see the image of part right eye, in general three-dimensional visual effect will be presented, in this patent, stereoeffect is an auxiliary function, importantly light can by focus vision to farther position by the device that this patent provides.
In addition, screen pixels is more, then screen pixels spacing is little, when screen pixels spacing is less, human eye does not more feel difference, then picture is more clear truer, therefore, same during design grating, we wish that image feels undistorted through device relief people, accomplish this point, just require that d1 and d2 is the smaller the better, make in microcosmic distance, when human eye cannot distinguish O1 point and O2 point, can think same point, therefore, the visual focus of people drops on O '.Wherein, microcosmic distance is exactly very little distance, little to naked eyes be difficult to maybe cannot distinguish.
