Description

A longitudinal chromatic aberration adjustment system based on geometric phase liquid crystal lens Technical Field

[0001] The present invention belongs to the field of optical display, and in particular relates to a longitudinal chromatic aberration adjustment system based on a geometric phase liquid crystal lens. Background Art

[0002] When a viewer looks at a nearby object, the lens in the eye adjusts the image of the short-wavelength light to fall near the retina, while the image of the long-wavelength light to fall behind the retina, causing the retina to tend to move backward, which in turn causes the eyeball to form a force to grow backward longitudinally, which will lead to myopia in the long run.

[0003] Given the above-mentioned problems, it is necessary to reduce the incidence of myopia by eliminating the interfering factors of longitudinal chromatic aberration, without introducing additional diopters. Existing solutions using traditional refractive optical elements are too bulky, unsuitable for long-term wear, and result in a poor user experience.

[0004] Summary of the Invention

[0005] The present invention is proposed based on the above-mentioned requirements of the prior art. The technical problem to be solved by the present invention is to provide a longitudinal chromatic aberration adjustment system and glasses based on geometric phase liquid crystal lenses to improve the user's wearing experience.

[0006] In order to solve the above problems, the technical solutions provided by the present invention include:

[0007] Provided is a longitudinal chromatic aberration adjustment system based on a geometric phase liquid crystal lens, comprising: a geometric phase liquid crystal lens, which changes the imaging focal lengths of different bands of visible light incident on the geometric phase liquid crystal lens and reverses the size relationship of the imaging focal lengths of different visible light bands; a circular polarizer, which modulates the light incident on the circular polarizer into circularly polarized light and eliminates stray light; and a preset lens, which combines with the geometric phase liquid crystal lens to reduce the optical focal length. After the incident light passes through the geometric phase liquid crystal lens, the circular polarizer, and the preset lens, different visible light bands are imaged on the viewer's retina, eliminating longitudinal chromatic aberration.

[0008] Through the above-mentioned arrangement, the geometric phase liquid crystal lens, the circular polarizer, and the preset lens are combined to enable the incident light to have substantially the same focal length on the retina of the viewer's eye, thereby eliminating the interference of longitudinal errors on eye imaging. Among them, the geometric phase liquid crystal lens is combined with the viewer's lens to eliminate the different focal lengths caused by different wavelengths. The circular polarizer ensures the normal operation of the above-mentioned system and avoids ghosting and stray light. The preset lens is used to cooperate with the geometric phase liquid crystal lens to form an appropriate optical focal length, thereby improving the viewing experience.

[0009] Preferably, the longitudinal chromatic aberration adjustment system based on the geometric phase liquid crystal lens also includes a sub-module, and the sub-module includes the geometric phase liquid crystal lens, a circular polarizer and a preset lens. A plurality of the sub-modules are arranged in a preset manner to form the longitudinal chromatic aberration adjustment system based on the geometric phase liquid crystal lens.

[0010] By setting up sub-modules arranged in a preset manner, the perspective resolution problem caused by lateral chromatic aberration is avoided, ensuring the viewer's experience.

[0011] Preferably, the refractive power of the geometric phase liquid crystal lens is a first refractive power less than zero, the refractive power of the preset lens is a second refractive power greater than zero, and the sum of the first refractive power and the second refractive power is 0.

[0012] The aforementioned arrangement allows the longitudinal chromatic aberration adjustment system to maintain the characteristics of plano lenses, making it suitable for both those experiencing myopia control and those with myopia. For those experiencing myopia control, the aforementioned system eliminates the effects of longitudinal chromatic aberration on the eyes, preventing axial elongation and effectively preventing and controlling myopia. For those experiencing myopia, the simple combination of the longitudinal chromatic aberration adjustment system and ordinary corrective lenses can simultaneously achieve the effects of correcting myopia and eliminating longitudinal chromatic aberration, making it suitable for most myopic individuals. Simply overlaying a longitudinal chromatic aberration adjustment system with the characteristics of plano lenses on daily myopia glasses provides a high degree of adaptability.

[0013] Preferably, the absolute value of the first refractive power is greater than the absolute value of the second refractive power.

[0014] Through the above-mentioned arrangement, the longitudinal chromatic aberration adjustment system has a certain refractive power, and the effect of correcting myopia and eliminating longitudinal chromatic aberration can be directly achieved through the system. The refractive power of the longitudinal chromatic aberration adjustment system can be individually adjusted according to the actual eye condition of the viewer without the need to combine it with myopia correction lenses. The overall structure of the longitudinal chromatic aberration adjustment system is lightweight and highly targeted.

[0015] Preferably, the first diopter ranges from -10D to -1D; the second diopter ranges from 1D to 10D.

[0016] Through the above-mentioned setting, the diopter of the system can be adjusted within a relatively large range to be suitable for most people.

[0017] Preferably, the geometric phase liquid crystal lens includes a photo-alignment layer and a multi-layer liquid crystal layer disposed on the photo-alignment layer; the bottom molecules in the liquid crystal layer connected to the photo-alignment layer are arranged according to the arrangement of the molecules in the photo-alignment layer.

[0018] The above configuration is used to improve light efficiency.

[0019] Preferably, the molecules in adjacent liquid crystal layers are arranged in the same direction.

[0020] The above configuration is used to improve light efficiency.

[0021] Preferably, the liquid crystal molecules in the liquid crystal layer form a helical structure along the first direction.

[0022] The above configuration is used to improve light efficiency.

[0023] Preferably, the angle of the molecules in the plane of the photo-alignment layer satisfies the condition Where f is the focal length of the geometric phase liquid crystal lens, λ is the wavelength, β(x,y) is the high-order phase term, x is the abscissa of the plane where the liquid crystal lens is located, and y is the ordinate of the plane where the liquid crystal lens is located.

[0024] Preferably, the area of ​​the plane where the submodule is located is 0.25 square millimeters to 25 square millimeters.

[0025] Also provided are glasses comprising lenses, wherein the lenses include any one of the above-mentioned longitudinal chromatic aberration adjustment systems based on geometric phase liquid crystal lenses.

[0026] Through the above arrangement, a lightweight glasses structure is formed according to the actual situation of the viewer, thereby effectively eliminating the influence of longitudinal chromatic aberration on the viewer's viewing experience.

[0027] Compared with the prior art, the present invention eliminates longitudinal chromatic aberration by setting a geometric phase liquid crystal lens to cooperate with the lens of the eye, eliminates ghosting and stray light by setting a circular polarizer, and forms a suitable optical focal length by setting a preset lens to cooperate with the geometric phase liquid crystal lens. Through the above settings, a good viewing experience is achieved while eliminating longitudinal chromatic aberration; multiple sub-modules are set at the same time, and the sub-modules are arranged in a preset manner to avoid the perspective resolution caused by the generated lateral chromatic aberration; in addition, the refractive power of the geometric phase liquid crystal lens is set to enable flexible use in different scenarios; and the level of the geometric phase liquid crystal lens is adjusted to improve the light efficiency of the liquid crystal lens in the visible light band.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

It will be understood that devices are multifunctional regardless of their orientation in space.

[0046] To facilitate understanding of the embodiments of the present application, further explanation will be given below with reference to specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present application.

[0047] Example 1

[0048] When a viewer observes a distant object, light entering the eye is focused by the lens 5. However, because the lens 5 has different refractive indices for light in different wavelength bands, light of different wavelengths forms images at different locations in the eye. When the viewer is looking far away, the lens 5 is in a relaxed state. At this point, the focal length of the short-wavelength (blue) image is smaller than that of the medium-wavelength (green) image, and the focal length of the medium-wavelength image 2 is smaller than that of the long-wavelength (red) image. If the medium-wavelength image 2 is on the retina 4, the short-wavelength image 1 will fall in front of the retina 4, while the long-wavelength image 3 will fall behind the retina 4. If the short-wavelength image 1 is on the retina 4, both the medium-wavelength image 2 and the long-wavelength image 3 will be behind the retina 4. If the long-wavelength image 3 is on the retina 4, both the short-wavelength image 1 and the medium-wavelength image 2 will fall in front of the retina 4. As shown in Figure 1, the medium-band imaging 2 on the retina 4 can make the image of the distant object concentrated near the retina 4. At this time, there are images in front and behind the retina 4, which is relatively balanced. The retina 4 will not have a tendency to move forward or backward. Compared with the short-band imaging 1 on the retina 4 or the long-band imaging 3 on the retina 4, the medium-band imaging 2 on the retina 4 can make the overall image clarity the highest.

[0049] When a viewer is looking at a nearby object, as shown in FIG2 , if the lens 5 is still in a relaxed state, the light entering the eye will be adjusted and focused by the lens 5 , and the short-wavelength image 1 , the medium-wavelength image 2 , and the long-wavelength image 3 will all be located behind the retina 4 , and the overall image will be blurred.

[0050] When the viewer is looking at a nearby object and the lens 5 becomes thicker, as shown in Figure 3, the light entering the eye is focused and adjusted by the lens 5, and is often adjusted to the point where the short-band image 1 is located on the retina 4. The overall image seen is relatively clear. In this case, the lens 5 will not adjust again to make the medium-band image 2 on the retina 4. At this time, the medium-band image 2 and the long-band image 3 are both located behind the retina 4. Such signals will stimulate the growth of the medium-band image 2 and the long-band image 3 behind the eye, which will cause the eye axis to elongate, forming myopia or further deepening the degree of myopia.

[0051] Based on the above principles, this embodiment provides a longitudinal chromatic aberration adjustment system 7 based on a geometric phase liquid crystal lens, as shown in FIG. 4-10 .

[0052] The longitudinal chromatic aberration adjustment system 7 based on the geometric phase liquid crystal lens will be referred to as the "longitudinal chromatic aberration adjustment system" below. The longitudinal chromatic aberration adjustment system 7 includes a plurality of submodules 6. The area of ​​the plane where the submodules 6 are located is 0.25 square millimeters to 25 square millimeters. The plurality of submodules 6 are arranged in an array to avoid the problem of low perspective resolution caused by lateral chromatic aberration. For example, as shown in FIG4 , the submodules 6 are rectangular and arranged in the form of three rows and four columns. There is no limitation on the shape and arrangement of the plurality of submodules 6. The area occupied by the submodules in the plane is 0.25 square millimeters to 25 square millimeters.

[0053] As shown in FIG6 , the submodule 6 includes a geometric phase liquid crystal lens 601 .

[0054] The geometric phase liquid crystal lens 601, shown in Figure 5, is a planar diffractive optical element. When parallel light in the visible wavelength range is incident on the geometric phase liquid crystal lens 601, the focal length of the short-wavelength image 1 passing through the geometric phase liquid crystal lens 601 is greater than the focal length of the medium-wavelength image 2, and the focal length of the medium-wavelength image 2 is greater than the focal length of the long-wavelength image 3. In other words, the longitudinal chromatic aberration after passing through the geometric phase liquid crystal lens 601 is opposite to the longitudinal chromatic aberration after passing through the lens 5 or a traditional refractive optical element. The diopter of the geometric phase liquid crystal lens is set between -10D and -1D.

[0055] The configuration of the geometric phase liquid crystal lens 601 is shown in Figures 7 to 10, and includes a light alignment layer 601A and a liquid crystal 601B. The bottom layer is the light alignment layer 601A, and the light alignment layer molecules 9 are arranged as shown in Figures 9 and 10. Specifically, the angle of the light alignment layer molecules 9 in the plane is The distribution meets the conditions Where f is the focal length of the geometric phase liquid crystal lens, λ is the wavelength, β(x,y) is the high-order phase term, and x and y are the coordinates of the plane where the liquid crystal lens is located. N layers of liquid crystal 601B are disposed above the photo-alignment layer 601A. The bottommost molecules of the liquid crystal 601B adjacent to the photo-alignment layer 601A are arranged in the same manner as the molecules 9 in the photo-alignment layer. The molecules in contact between adjacent liquid crystals 601B in the N layers of liquid crystal 601B are arranged in the same direction, and each layer of liquid crystal 601B has a helical structure 8 in the first direction. This helical structure 8 is formed spontaneously. The spontaneous helical structure 8 is as follows: the thickness of the liquid crystal molecules in the i-th layer of liquid crystal 601B is d i , and the liquid crystal molecules in this layer rotate at an angle of α in the first direction i , where i=1~N, the geometric phase liquid crystal lens 601 has an efficiency greater than 90% in the visible light band.

[0056] Compared to traditional lenses, the geometric phase liquid crystal lens 601 can achieve greater reverse longitudinal chromatic aberration with a smaller optical power. As illustrated by the experimental data shown in Figure 11, a 50cm focal length (2.0D) lens made of traditional NBK7 glass has an Abbe number of approximately 64. Its optical power was measured to be 2.01D under blue light (488nm), 2.0D under green light (532nm), and 1.98D under red light (633nm). The optical power difference between blue and red light is 0.03D. The measured optical power of the geometric phase liquid crystal lens 601 under blue (488nm), green (532nm), and red (633nm) is 1.85D, 1.99D, and 2.36D, respectively. The optical power difference between blue and red light is -0.51D. Based on the above experimental data, it can be seen that the optical power-wavelength dispersion relationship of the geometric phase liquid crystal lens 601 is opposite to that of a traditional glass lens. The absolute value of the Abbe number of the geometric phase liquid crystal lens 601 is approximately 17 times that of the traditional glass material NBK7. Therefore, the geometric phase liquid crystal lens 601 can achieve a large reverse longitudinal chromatic aberration with a relatively low optical power.

[0057] The longitudinal chromatic aberration adjustment system 7 also includes a circular polarizer 602 and a preset lens 603. The relative arrangement order of the geometric phase liquid crystal lens 601, the circular polarizer 602, and the preset lens 603 can be interchanged. The circular polarizer 602 is provided to ensure the normal operation of the geometric phase liquid crystal lens 601 and to prevent ghosting and stray light. The refractive power of the preset lens 603 is set between 1D and 10D. The preset lens 603 can cooperate with the geometric phase liquid crystal lens 601 to form a suitable optical focal length. Without the preset lens 603, a larger optical focal length would be formed, seriously affecting the viewing experience.

[0058] As shown in FIG12 , regardless of whether the light is emitted by a near object or a far object, after passing through the longitudinal chromatic aberration adjustment system 7 and the viewer's lens 5, the entire band of visible light will be focused on the viewer's retina 4 without spatial separation, i.e., without longitudinal chromatic aberration, thereby being able to avoid, to a limited extent, the elongation of the eyeball caused by longitudinal chromatic aberration.

[0059] Furthermore, after the light is modulated by the longitudinal chromatic aberration adjustment system 7, the focal length of the long-waveband imaging 3 is made smaller than that of the short-waveband imaging 1, so as to reverse the longitudinal chromatic aberration, thereby producing the effect of reversing the signal stimulating the longitudinal elongation of the eyeball.

[0060] In some application scenarios, the longitudinal chromatic aberration adjustment system 7 maintains the characteristics of a plano lens, that is, the system diopter is 0, the diopter of the geometric phase liquid crystal lens 601 is opposite to the diopter of the preset lens 603, and for example, the diopter of the geometric phase liquid crystal lens 601 is -5D, and the diopter of the preset lens 603 is 5D. The longitudinal chromatic aberration adjustment system 7 with the characteristics of a plano lens is suitable for people with normal eyes to prevent and control myopia. In addition, the simple combination of the longitudinal chromatic aberration adjustment system 7 and ordinary myopia correction lenses can simultaneously achieve the effects of correcting myopia and eliminating longitudinal chromatic aberration, so that it is suitable for most myopic people. It is only necessary to superimpose a longitudinal chromatic aberration adjustment system 7 with the characteristics of a plano lens on the myopia glasses used in daily life, and the flexibility of adaptation is high.

[0061] In some application scenarios, the longitudinal chromatic aberration adjustment system 7 can be set to have a certain refractive power. Specifically, the absolute value of the refractive power of the geometric phase liquid crystal lens 601 is set to be greater than the absolute value of the refractive power of the preset lens 603. At this time, the effects of correcting myopia and eliminating longitudinal chromatic aberration can be achieved simultaneously. The refractive power of the longitudinal chromatic aberration adjustment system 7 can be personalized adjusted according to the actual eye condition of the viewer without the need to combine it with myopia correction lenses. The overall structure of the longitudinal chromatic aberration adjustment system 7 is lightweight and highly targeted.

[0062] The above-mentioned arrangement can eliminate the longitudinal chromatic aberration entering the viewer's eyes, thereby avoiding the adverse effect of lengthening the eye axis caused by the longitudinal chromatic aberration. At the same time, the longitudinal chromatic aberration adjustment system 7 is combined with appropriate lenses to simultaneously achieve myopia correction and elimination of longitudinal chromatic aberration according to the viewer's actual eye use conditions.

[0063] Example 2

[0064] This embodiment provides a pair of glasses, which include lenses. The lenses include the longitudinal chromatic aberration adjustment system 7 based on the geometric phase liquid crystal lens 601 in Example 1.

[0065] Through the above-mentioned setting, the appropriate longitudinal chromatic aberration adjustment system 7 based on the geometric phase liquid crystal lens 601 is matched according to the different eye conditions of the wearer to effectively eliminate the longitudinal chromatic aberration, thereby avoiding the elongation of the eye axis caused by the longitudinal chromatic aberration, which is beneficial to the prevention and relief of myopia.

[0066] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of this application. It should be understood that the above description is only the specific implementation methods of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
