	As shown in Figure 2, glare is a common phenomenon in people's lives. In general, disabling glare and adaptive glare are more irritating to people, but they are short-lived and easily noticed, while the phenomenon of discomfort glare formed by reflections from surfaces like instruments and meters, although widespread, is less likely to attract attention, but continuous damage can make people's vision deteriorate and cause harm to human health.

	The generation of glare is related to the location and brightness of the light source, as shown in Figure 3. According to the classification of the light source that generates glare, glare can be divided into direct glare and reflected glare.		The generation of glare is related to the location and brightness of the light source, as shown in Figure.3. According to the classification of the light source that generates glare, glare can be divided into direct glare and reflected glare.

	Direct glare is caused by the presence of bright light sources in the human field of vision, for example, blinding street lights, looking up at the sun, LED displays with too much brightness in busy streets, etc. Reflected glare is caused by the reflection of light from the surface of an object, for example, on shiny metal surfaces with a large reflection coefficient, the sunlight can easily enter the human eye due to its reflection and cause some harm to the human body.

	The beam is adjusted from its original path to the given path, given the path through which the beam has to pass. The way the beam path is given is usually by using two scales, such as diaphragms, where the line at the center of the diaphragm uniquely defines the beam path. During the adjustment process, the diaphragms are not moved, but rather the position (and height) of the light source is adjusted by translation and the angle of the light source is adjusted by rotation so that the beam from the light source can pass through the centers of both diaphragms at the same time. This operation is not only used in the light path construction, but also useful in the light path recovery. A common case where the beam path has been set is a parallel/horizontal path. In this case, it is also possible to use only one diaphragm and place it as far and as near as needed in the adjustment process, so that both diaphragms can serve the same purpose. Figure 4-1 illustrates the adjustment procedure in this way. First, the diaphragm is placed close to the light source, and the height and position of the light source are adjusted in translation so that the beam passes through the center of the diaphragm, as shown in step (a) in Figure 4-1; then the diaphragm is placed far away along the path, and the angle of the light source is adjusted in rotation so that the beam passes through the center of the diaphragm again, as shown in step (b); (c) when the diaphragm is again close to the light source and the beam is deflected from the near diaphragm, the light source is adjusted in translation position and height, so that it passes through the center of the near diaphragm; (d) then put the diaphragm at a distant position, turn the angle of the adjustable light source, so that the beam passes through the center of the diaphragm; repeatedly carry out the operation of (c) and (d) until when the diaphragm in the near and far position, both can be passed by the beam from the center as shown in figure (e), the adjustment of horizontal/parallel is completed. If you use two diaphragms, the operation principle is the same, based on the proximal diaphragm to pan to adjust the light source position and height, based on the distal diaphragm rotation to adjust the angle of the light source.

When liquid crystal molecules are arranged in an orderly manner, they will show anisotropy. By applying a certain voltage to the liquid crystal box, the orientation of the liquid crystal layer molecules can be changed, thus the optical properties of the liquid crystal box also change, which is a rare characteristic of other materials and an important reason why liquid crystal materials are widely used.

	The beam is adjusted from its original path to the given path, given the path through which the beam has to pass. The way the beam path is given is usually by using two scales, such as diaphragms, where the line at the center of the diaphragm uniquely defines the beam path. During the adjustment process, the diaphragms are not moved, but rather the position (and height) of the light source is adjusted by translation and the angle of the light source is adjusted by rotation so that the beam from the light source can pass through the centers of both diaphragms at the same time.

In this case, it is also possible to use only one diaphragm and place it as far and as near as needed in the adjustment process, so that both diaphragms can serve the same purpose.

	Comparing the above pictures, we can see that as the number of pixel points increases, the number of colour blocks in the liquid crystal pointing vector distribution map becomes more and more, and the more uniform the distribution of liquid crystal molecules pointing vectors in the region; at the same time, visually and intuitively, the diffracted light intensity distribution increases with the number of pixel points, from concentrating on one point to the surrounding distribution, and when the pixel points are selected as 512×512, the effect of light scattering is The best. Unlike the usual two-dimensional grating, the liquid crystal orientation angle can be set randomly to produce a micro-zone orientation structure similar to a two-dimensional code pattern, i.e. a random grating structure, which will cause light to propagate in all directions, achieving the purpose of anti-glare.

	In order to more accurately and scientifically describe the relationship between the number of pixel selection points and the light dispersion effect, and further study and analyse the stability of random orientation, on the basis of the existing program, the design uses the std2 function to process the mean square difference of the light intensity magnitude at each point each time the program is run. The greater the mean squared difference, the greater the light intensity at some diffraction level, and the smaller the mean squared difference, the better the light dispersion. The mean squared deviation values were A, B, C, D, E, F, G, H and I for 4 x 4, 8 x 8, 16 x 16, 32 x 32, 64 x 64, 128 x 128, 256 x 256, 512 x 512 and 1024 x 1024 pixel points, respectively, and the results were repeated 15 times for each case as follows.

	As can be seen from the data in the graph, as the number of pixel points selected increases, the value of the mean squared deviation of the light intensity becomes progressively smaller, indicating that the scattering effect is getting better and better, in line with the results obtained from visual observation of the stereogram of the light intensity distribution of the emitted light. In addition, it can be observed that the more the number of pixel dots, the more stable the light scattering effect of the 15 runs with that number of dots, i.e. the more uniform the liquid crystal tends to point in the wrong direction; in particular, the mean squared difference value does not change when the number of dots is 512 x 512 and 1024 x 1024, indicating that when the number of dots reaches a certain level, the randomness of the orientation angle of the liquid crystal molecules no longer have an effect on the light scattering effect. At this point, it is no longer meaningful to increase the number of selected pixels, and the system maintains the highest level of light dispersion, achieving a stable anti-glare effect.

	For the TEB300 liquid crystal, the box thickness ranges from 0.6917 μm to 0.8436 μm. Therefore, with the optimal value of the liquid crystal box orientation parameter, the effect of different box thickness values on the light intensity distribution was further verified by simulating the mean squared deviation as follows.

	As can be seen from the data in the table, the mean squared deviation of the light intensity distribution becomes larger as the box thickness increases, and the mean squared deviation of the reflected light intensity distribution basically remains the same when the box thickness is between 0.8267 μm and 0.8436 μm, i.e. the reflected light phase delay tends to π. This indicates that the reflected light diffraction efficiency also remains basically the same at this time, which is consistent with the curve of reflected light diffraction efficiency with box thickness in Figure 3-14 and Figure 3-15. This is consistent with the variation of the reflected light diffraction efficiency with box thickness in Figures 3-14 and 3-15.
