本发明涉及光学领域，尤其涉及到一种用于设备屏幕的贴膜。The invention relates to the field of optics, in particular to a film for device screens.
背景技术Background technique
随着可视化电子产品的日益普及，人们每天观看屏幕的时间也随之增加，如果持续近距离观看屏幕，很容易导致近视，但是人的用眼习惯很难改变，特别是少年儿童，由于过早接触可视化电子产品，目前的近视率已超过40％。With the increasing popularity of visual electronic products, people spend more time watching screens every day. If you continue to watch the screen at a close distance, it is easy to cause myopia, but it is difficult to change people's eye habits, especially children. Contact with visual electronic products, the current myopia rate has exceeded 40%.
要解决上述用眼距离过近的问题，可以从两个方面来考虑：To solve the above-mentioned problem of too close eye distance, two aspects can be considered:
制造一种装置用于控制视距，使得视距大于用眼距离，类似于看镜子中反射的景象，眼睛虽然离镜子近，但实际上视距可以很远。Make a device to control the viewing distance, so that the viewing distance is greater than the distance of the eyes, similar to looking at the reflection in the mirror. Although the eyes are close to the mirror, the viewing distance can actually be very far.
制造一种装置，使得只有在被观察物体一定距离范围内才能得到最佳观看效果，这是一种约束装置。Making a device so that the best viewing effect can only be obtained within a certain distance from the observed object is a constraint device.
人眼之所以能产生立体视觉，是因为左眼与右眼是从不同的角度观察事物的，因此左右眼看到的景象存在一定的角度差，人脑在合并左眼和右眼的景象时就会产生立体视觉。The reason why the human eye can produce stereoscopic vision is because the left eye and the right eye observe things from different angles, so there is a certain angle difference between the scenes seen by the left and right eyes, and the human brain will automatically merge the scenes of the left and right eyes. Stereoscopic vision will be produced.
目前最流行的裸眼3D视觉技术是使用柱镜光栅进行分光处理，该柱镜光栅贴膜横截面的下表面为平面，上表面是并列的弧面，类似于凸透镜，屏幕像素点P的光线穿过光栅时会分别向左右两边折射，此时，左眼看到的是P1，右眼看到的是P2，由于P1和P2存在角度差，因此人就会产生立体视觉，这种柱镜光栅增加视距的幅度小于1％，不具有实际应用价值。At present, the most popular naked-eye 3D vision technology is to use lenticular lens grating for spectroscopic processing. The lower surface of the cross-section of the lenticular lenticular film is flat, and the upper surface is a juxtaposed arc surface, similar to a convex lens. The light from the pixel point P of the screen passes through The grating will be refracted to the left and right sides respectively. At this time, what the left eye sees is P1, and what the right eye sees is P2. Because there is an angle difference between P1 and P2, people will have stereo vision. This cylindrical lens grating increases the viewing distance The range is less than 1%, which has no practical application value.

具体的，参考图2，图2是本发明实施例提供的一种计算三棱柱镜视距的方法示意图。如图2所示，根据基本的几何推理得到以下等式，以下所有夹角都以角度为单位：Specifically, refer to FIG. 2 , which is a schematic diagram of a method for calculating the viewing distance of a triangular prism provided by an embodiment of the present invention. As shown in Figure 2, the following equations are obtained based on basic geometric reasoning, and all the included angles below are in angle units:
1)a＝x1) a=x
2)r＝sin(a)/sin(b)＝sin(d)/sin(c)2) r=sin(a)/sin(b)=sin(d)/sin(c)
3)y＝d+Θ3) y=d+Θ
4)(d-c)+Θ+(90–x)+90+b＝1804) (d-c)+Θ+(90–x)+90+b=180
5)thick*tan(a–b)＝see*tan(Θ)5) thick*tan(a–b)=see*tan(Θ)
整理上述等式可得以下公式：Rearranging the above equations, the following formula can be obtained:
公式1：a＝x；Formula 1: a=x;
公式2：b＝arcsin(sin(x)/r)；Formula 2: b=arcsin(sin(x)/r);
公式3：c＝y–x+b；Formula 3: c=y-x+b;
公式4：d＝arcsin(r*sin(c))；Formula 4: d=arcsin(r*sin(c));
公式5：Θ＝y–d；Formula 5: Θ = y – d;
公式6：see＝thick*tan(a–b)/tan(Θ)。Formula 6: see=thick*tan(a–b)/tan(Θ).
由公式1到公式6可以推出以下约束条件：From formula 1 to formula 6, the following constraints can be deduced:
本光栅必须尽量避免全反射的情况发生，由全反射的标准公式：sin(全反射角)＝1/r可知，b和c不能大于arcsin(1/r)；The grating must try to avoid the occurrence of total reflection. According to the standard formula of total reflection: sin (total reflection angle) = 1/r, b and c cannot be greater than arcsin (1/r);
同时，Θ为正和负都是可以的，但为了计算方便，下面给出的计算结果和结论都假设Θ为正数。At the same time, Θ is both positive and negative, but for the convenience of calculation, the calculation results and conclusions given below all assume that Θ is a positive number.
在实际使用中还需要考虑使用者的瞳距s、用眼距离m，从公式1到公式6可以得出以下有用的结论：In actual use, the user's interpupillary distance s and eye distance m also need to be considered. From formula 1 to formula 6, the following useful conclusions can be drawn:
1)x越大，see就越大，效果越好，但x不建议大于45度，因为大于45度时，在装置内的下表面的折射光可能会被临近的光栅阻挡，导致最终图像失真，建议值为45度；1) The larger the x, the larger the see, and the better the effect, but it is not recommended that x be greater than 45 degrees, because when it is greater than 45 degrees, the refracted light on the lower surface of the device may be blocked by the adjacent grating, resulting in distortion of the final image , the recommended value is 45 degrees;
2)thick越大，see就越大，效果越好；2) The bigger the thickness, the bigger the see and the better the effect;
3)r越大，see就越大，效果越好。3) The larger r is, the larger the see is, and the better the effect is.
假设本发明的使用者是儿童，其瞳距s＝5.5cm，屏幕为手机屏幕，习惯用眼距离m＝25cm。沿用图2的变量，假设r＝2.5，x＝50，thick＝1cm。把上述参数代入本发明的计算公式，通过调节y的值，使得下面的公式成立：s/2＝(m+see)*tan(Θ)，该公式使得see尽可能大。经计算，当角度y≈47.5度时，等式成立，此时，r＝2.5,a＝50.0,b＝17.84,c＝15.34,d＝41.42,x＝50.0,Θ＝6.08,全反射角＝23.58,thick＝1.0,see＝5.9。显然本次计算结果满足本发明的约束条件，即在本情况下，视距see增加了5.9cm，视距增加率see/m＝23.6％。Assuming that the user of the present invention is a child, the interpupillary distance s=5.5cm, the screen is a mobile phone screen, and the habitual eye distance m=25cm. Continue to use the variables in Figure 2, assuming r=2.5, x=50, thickness=1cm. Above-mentioned parameters are substituted into the calculation formula of the present invention, by adjusting the value of y, make following formula set up: s/2=(m+see)*tan (Θ), this formula makes see as large as possible. After calculation, when the angle y≈47.5 degrees, the equation is established, at this time, r=2.5, a=50.0, b=17.84, c=15.34, d=41.42, x=50.0, Θ=6.08, total reflection angle= 23.58, thick=1.0, see=5.9. Apparently, the calculation result of this time satisfies the constraints of the present invention, that is, in this case, the viewing distance see increases by 5.9 cm, and the viewing distance increase rate see/m=23.6%.
在实际生产的时候，增加r和x可以减少thick，权衡过程有生产商把握，不在本实施例中探讨。In actual production, increasing r and x can reduce the thickness, and the trade-off process is determined by the manufacturer, which will not be discussed in this embodiment.
假设本发明的使用者是成年人，其瞳距s＝6cm，屏幕为电视屏幕，用眼距离m＝200cm，假设r＝2.5,x＝50,thick＝1cm。使用本发明实施例提供的方法计算，可得到如下结果：当角度y≈49.7度时，r＝2.5,a＝50.0,b＝17.84,c＝17.54,d＝48.90,x＝50.0,Θ＝0.8,全反射角＝23.58,thick＝1.0,see＝45.7,即额外增加45.7cm的视距，视距增加率为see/m＝22.85％。Assuming that the user of the present invention is an adult, the interpupillary distance s=6cm, the screen is a TV screen, the eye distance m=200cm, r=2.5, x=50, thickness=1cm. Calculated using the method provided by the embodiment of the present invention, the following results can be obtained: when the angle y≈49.7 degrees, r=2.5, a=50.0, b=17.84, c=17.54, d=48.90, x=50.0, Θ=0.8 , total reflection angle = 23.58, thickness = 1.0, see = 45.7, that is, an additional 45.7cm of viewing distance is added, and the viewing distance increase rate is see/m = 22.85%.
假设本发明的使用者是成年人，其瞳距s＝6cm，屏幕为手机屏幕，希望控制用户的用眼距离m＝35cm。假设r＝1.5,x＝45,thick＝0.1cm。使用本发明实施例的方法计算，可得到如下结果：r＝1.5,a＝45.0,b＝28.13,c＝21.63,d＝33.54,x＝45.0,Θ＝4.94,全反射角＝41.81,thick＝0.1,see＝0.35,即当本发明的参数满足以上计算结果时，可以控制屏幕的最佳观看距离为m＝35cm。Assuming that the user of the present invention is an adult with an interpupillary distance of s=6cm and a screen of a mobile phone, it is desired to control the user's eye distance m=35cm. Suppose r=1.5, x=45, thickness=0.1cm. Calculated using the method of the embodiment of the present invention, the following results can be obtained: r=1.5, a=45.0, b=28.13, c=21.63, d=33.54, x=45.0, Θ=4.94, total reflection angle=41.81, thickness= 0.1, see=0.35, that is, when the parameters of the present invention meet the above calculation results, the optimal viewing distance of the control screen is m=35cm.
如图3，图3是本发明实施例提供的一种用于设备屏幕的贴膜的效果示意图。光栅上表面和下表面均为等腰三角形，上表面等腰三角形凸起夹角为y，下表面等腰三角形凸起夹角为x，x不等于y。由于上下表面凸起夹角x和y不相同，所以光栅的入射光线和出射光线不平行，存在角度差，当x﹥y时，从O1点发出的光线只会进入人的左眼，右眼看不到，同理，右眼能看到O2点但左眼看不到；当x﹤y时，从O1点发出的光线只会进入人的右眼，左眼看不到，同理，左眼能看到O2点但右眼看不到。As shown in FIG. 3 , FIG. 3 is a schematic diagram of the effect of a film applied to a device screen provided by an embodiment of the present invention. Both the upper surface and the lower surface of the grating are isosceles triangles, the angle between the protrusions of the isosceles triangles on the upper surface is y, and the angle between the protrusions of the isosceles triangles on the lower surface is x, and x is not equal to y. Since the angle x and y are different between the upper and lower surfaces, the incident light and outgoing light of the grating are not parallel, and there is an angle difference. When x > y, the light emitted from O1 will only enter the left eye of the person, and the right eye will see No, in the same way, the right eye can see the O2 point but the left eye cannot; See O2 point but not with right eye.
具体的，如图3所示，假设从O1垂直于屏幕发射出激光，首先经过下表面的折射，因为任何物体的折射率都比空气大，因此入射光进入材料后向左偏移了，图3中的a一定大于b，向左的偏移角度为a-b，激光的光线继续传播，当所述光线传播到光栅的上表面时又发生折射，该折射是光线从光栅进入到空气，因此d一定大于c。我们延长出射光，经过几次三角形定理的计算，可以得出Θ＝y–d一定大于0，即这条从O1点发出的垂直光线经过如图3的装置后必定会向左偏移的，人的两只眼睛之间是有距离的，平均为6厘米，光线向左偏移则被左眼观察到。Specifically, as shown in Figure 3, assuming that the laser is emitted from O1 perpendicular to the screen, it first passes through the refraction of the lower surface, because the refractive index of any object is greater than that of air, so the incident light is shifted to the left after entering the material, as shown in Figure In 3, a must be greater than b, and the leftward offset angle is a-b. The laser light continues to propagate, and when the light propagates to the upper surface of the grating, refraction occurs again. This refraction is the light entering the air from the grating, so d must be greater than c. We extend the outgoing light, and after several calculations of the triangle theorem, it can be concluded that Θ=y–d must be greater than 0, that is, the vertical light emitted from O1 will definitely shift to the left after passing through the device as shown in Figure 3. There is a distance between the two eyes of a person, the average is 6 cm, and the light shifts to the left and is observed by the left eye.
同理，若O1点发出的垂直光线经过图3的装置后向左偏移，则O2点发出的垂直光线经过图3的装置后向右偏移，因为是等腰三角形，所以相当于一半的图像会让左眼看到，一半的图像让右眼看到，预先设定d1和d2小于0.5毫米，如图1所示，d1是上表面等腰三角形的底边，d2是下表面等腰三角形的底边，这种微观尺度人是无法分辨的，于是我们感觉到左眼看到了全部图像，右眼也看到全部图像，而且这个图像的位置不是在O点，而是在O’点，相当于视线聚焦到更远的位置。In the same way, if the vertical ray emitted by O1 passes through the device in Figure 3 and then shifts to the left, then the vertical ray emitted by O2 passes through the device in Figure 3 and then shifts to the right. Because it is an isosceles triangle, it is equivalent to half of the The image will be seen by the left eye, and half of the image will be seen by the right eye. Preset d1 and d2 to be less than 0.5 mm, as shown in Figure 1, d1 is the base of the isosceles triangle on the upper surface, and d2 is the bottom edge of the isosceles triangle on the lower surface Bottom, this kind of microscopic scale is indistinguishable for human beings, so we feel that the left eye sees all the images, and the right eye also sees all the images, and the position of this image is not at point O, but at point O', which is equivalent to The sight is focused to a farther position.
同理类推，实际上一个点光源发出的光线是发散到四面八方的，以图3为例，假设入射光线本来就是向左偏的，于是出射光则偏向更左的位置，如果入射光线本来是向右偏的，于是出射光则偏向更右的位置，从分布来看，射入左眼的光线比右眼多，即左眼也能看到部分右眼的图像，综合来看就会呈现出立体的视觉效果，在本专利中，立体效果只是一个附属功能，重要的是光线通过本专利提供的装置可以将视线聚焦到更远的位置。By analogy, in fact, the light emitted by a point light source diverges to all directions. Take Figure 3 as an example, assuming that the incident light is originally deflected to the left, so the outgoing light is deflected to the left. If the incident light is originally to the left Right-biased, so the outgoing light is biased to the right. From the distribution point of view, the light entering the left eye is more than the right eye, that is, the left eye can also see part of the image of the right eye. Comprehensively, it will show Three-dimensional visual effect, in this patent, three-dimensional effect is only an auxiliary function, the important thing is that light can focus the line of sight to a farther position through the device provided by this patent.
另外，屏幕像素越多，则屏幕像素间距小，当屏幕像素间距越小，人眼就越感觉不出差别，则画面就越清晰越真实，因此，设计光栅时同样，我们希望图像经过装置后让人感觉不失真，要做到这一点的话，就要求d1和d2越小越好了，使得在微观距离上，当人眼无法区分O1点和O2点，可认为是同一点，因此，人的视觉焦点落在O’。其中，微观距离就是很小的距离，小到肉眼很难或无法区分。In addition, the more screen pixels, the smaller the screen pixel pitch. When the screen pixel pitch is smaller, the human eyes will feel no difference, and the picture will be clearer and more real. Therefore, when designing the grating, we hope that the image will pass through the device. It does not make people feel distorted. To achieve this, it is required that d1 and d2 be as small as possible, so that at a microscopic distance, when the human eye cannot distinguish O1 and O2, they can be considered as the same point. Therefore, human The visual focus falls on O'. Among them, the microscopic distance is a very small distance, so small that it is difficult or impossible to distinguish with the naked eye.
