Description

Technical Field

[0001] The present invention belongs to the technical field of AR glasses, and in particular relates to a method for preparing fully-automatic anti-glare AR glasses. Background Art

[0002] Augmented reality (AR) technology refers to combining the principles of data collection, real-time rendering, and user interaction to superimpose digital information on the user's real vision, integrate real things with virtual things, and bring them into the real world to create a new visual environment. This not only enriches the user's visual experience, but also provides users with a more convenient and efficient way to obtain information. AR glasses developed using this principle are becoming more and more popular. However, during use, the visual experience will be affected due to the constant changes in the external light environment. For example, the light intensity range for the naked eye is 100 to 2000 lux. When the light intensity is greater than 2000 lux (such as outdoors in sunny weather), people will feel uncomfortable. For example, when wearing AR glasses outdoors in strong light, users will feel uncomfortable or even dizzy. On the other hand, the image may be unclear, uneven in color or residual images, affecting the visual experience. Existing AR glasses use films with low transmittance, which can effectively protect the field of view and provide good visual effects in strong outdoor light environments. However, in indoor or low-light environments, it is impossible to provide a sufficiently clear and bright field of view. Therefore, there is an urgent need for AR glasses that can automatically adjust and switch transmittance in different lighting environments. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the existing AR glasses cannot automatically adjust the light transmittance under different light intensities, affecting the user's visual experience, and to provide a fully automatic anti-glare AR glasses based on electrochromic technology.

[0004] The fully automatic anti-glare AR glasses prepared by the present invention add a fully automatic color-changing layer (purple electrochromic device) and a photosensitive sensor on the side of the AR glasses body away from the user's face. When light is irradiated onto the sensor, the sensor receives the light and detects the light in real time. When the illuminance detected is greater than 2000 lux, the sensor converts the light energy into an electrical signal. The control module receives the electrical signal, controls the power supply to apply a corresponding coloring voltage to the electrochromic device, drives the electrochromic device to work, reduces the transmittance of the AR glasses, and achieves the purpose of fully automatic anti-glare; when the detected illuminance is less than 2000 lux, the color of the automatic color-changing layer fades and remains transparent, providing a clear field of view for the user.

[0009] 2. Preparation of electrochromic solution:

[0011] The electrochromic material in step 2 is a mixture of a viologen compound and an ion storage material;

[0012] 3. Assembling electrochromic devices:

It uses a sensitive photoresistor sensor and is equipped with an adjustable potentiometer to adjust the intensity of the detected light.

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a fully automatic anti-glare AR glasses, wherein a viologen electrochromic device and a photosensitive sensor are assembled on the side of the AR glasses body away from the user's face, light is irradiated on the sensor, the sensor receives the light, and the light is detected in real time. When the illumination is detected to be greater than 2000 lux, the sensor converts light energy into an electrical signal, and the control module receives the electrical signal to control the power supply to apply a coloring voltage to the electrochromic device, driving the electrochromic device to work, and the viologen compound undergoes a reduction reaction in the electrolyte, and the positive divalent bipyridyl cation obtains an electron and is reduced to a positive monovalent free radical. There is a non-delocalized positive charge on this cation free radical, and a strong photoelectric transfer phenomenon occurs between molecules. The molar absorption coefficient of the viologen in this state is greatly improved, and the material is in a colored state, thereby realizing a substantial reduction in the light modulation amplitude of the device in a short time. The method is simple to operate, low in cost, does not require special equipment, and can realize automatic adjustment of the transmittance of AR glasses under different light environments without manual operation, providing users with the best visual experience.

[0049] Cleaning the ITO transparent conductive glass to obtain clean ITO transparent conductive glass;

[0050] In step 1, the ITO transparent conductive glass is cleaned according to the following steps: the ITO transparent conductive glass is ultrasonically cleaned with detergent, deionized water, acetone, and anhydrous ethanol in sequence, each ultrasonic cleaning time is 20 minutes, and then dried with nitrogen to obtain a clean ITO transparent conductive glass;

[0051] 2. Preparation of electrochromic solution:

[0052] The electrochromic material and the electrolyte salt are dissolved in a solvent and stirred for 30 minutes to obtain an electrochromic solution;

[0053] The electrochromic material described in step 2 is a mixture of 1,1'-di-n-octyl-4,4'-pyridinium dibromide (common name: octyl viologen) and ferrocene;

[0054] The solvent described in step 2 is propylene carbonate;

[0055] The electrolyte salt described in step 2 is lithium perchlorate;

[0056] The concentration of 1,1'-di-n-octyl-4,4'-pyridinium dibromide (common name: octyl viologen) in the electrochromic solution described in step 2 is 18 mmol / L, the concentration of ferrocene is 15 mmol / L, and the concentration of lithium perchlorate is 50 mmol / L;

[0057] 3. Assembling electrochromic devices:

[0058] A clean ITO transparent conductive glass is placed with the conductive surface facing upwards, and a circle of ultraviolet curing glue is applied on the conductive ITO using a glue dispenser to reserve a crystal filling port; another clean ITO transparent conductive glass is bonded with the conductive surface facing downwards to obtain an electrochromic material box; the electrochromic material box is evacuated, and then an electrochromic solution is poured into the evacuated electrochromic material box, and finally the crystal filling port is sealed with ultraviolet curing glue to obtain an electrochromic device;

[0059] The electrochromic device described in step 3 is in a transparent state when no voltage is applied, and is in a colored state when voltage is applied; reversible switching between two different optical states of transparency and coloring can be achieved;

[0060] 4. Assemble fully automatic anti-glare AR glasses:

[0061] The electrochromic device is compounded on the outer layer of the AR glasses body, and the photosensor is compounded on the outer layer of the electrochromic device. The photosensor, power supply, control module and electrochromic device are connected by copper wire, and soldering is used at the connection points. The AR glasses body and the electrochromic device, photosensor, power supply and control module are connected by ultraviolet curing glue to obtain fully automatic anti-glare AR glasses.

[0062] The brand of the UV curing adhesive described in step 3 and step 4 of Example 1 is Zolide, the model is D-6212, and the name is UV curing adhesive.

[0063] The photosensor described in step 4 of Example 1 is called a 4-pin photoresistor sensor module, which is purchased from telesky flagship store. It uses a sensitive photoresistor sensor and is equipped with an adjustable potentiometer to adjust the intensity of the detected light.

[0064] The control module described in step 4 of Example 1 is the control module disclosed in application number 202411343487.3, and the invention name is "A color-changing device and its temperature-adaptive color-changing control method".

[0065] The electrochromic device prepared in step 3 of Example 1 was powered on to perform a performance test. The results are as follows: Figure 2 As shown;

[0066] Figure 2 This is the color change diagram of the electrochromic device prepared in step 3 of Example 1;

[0067] After the electrochromic device (purpurogen electrochromic device) prepared in step 3 of Example 1 is assembled on the AR glasses, when the light sensor receives an external illumination lower than 2000 lux, the electrochromic device does not work and is in a power-off state. The electrochromic device is colorless and transparent, providing a good and clear field of vision for the user. When the light sensor receives light with an illumination higher than 2000 lux, the light sensor converts the optical signal into an electrical signal, the control module controls the power supply to emit a DC voltage of 1.3V, and the purpurogen electrochromic device performs an oxidation-reduction reaction under the 1.3V power-on condition, and the purpurogen is dark blue in color, the transmittance decreases rapidly, and the light intensity decreases.

[0068] The electrochromic device prepared by the invention has low operating voltage and good electrochromic performance.

[0069] The transmittance and response time of the electrochromic device were recorded using a CHI660 electrochemical workstation and a fiber optic spectrometer (Maya 2000-Pro, Ocean Optics). Figure 3 and Figure 4 As shown;

[0070] Figure 3 This is the UV-visible spectrum of the electrochromic device prepared in step 3 of Example 1;

[0071] Figure 4 This is a graph of the coloring and fading time of the electrochromic device prepared in step 3 of Example 1 at 600nm.

[0072] from Figure 3 It can be seen that the electrochromic device prepared using octyl viologen has a transmittance of 78% at 600nm, a transmittance of 6.7% in the colored state, and an optical modulation amplitude of up to 71.3%.

[0073] from Figure 4 It can be seen that the device takes only 6.8s to color and 5.6s to fade, and has a fast response.

[0074] Example 2: The difference between this example and Example 1 is that the electrochromic material described in step 2 is a mixture of ethyl viologen and ferrocene; the concentration of ethyl viologen in the electrochromic solution described in step 2 is 18 mmol / L, the concentration of ferrocene is 15 mmol / L, and the concentration of lithium perchlorate is 50 mmol / L. The other steps and parameters are the same as those in Example 1.

[0075] The electrochromic device prepared in Example 2 was tested for performance, and the test results are as follows:

[0076] The electrochromic device prepared in Example 2 has a fading voltage of 0 V, a coloring voltage of 1.3 V, a transparent state transmittance of 78.2%, a colored state transmittance of 8.9%, an optical modulation amplitude of 69.3%, a coloring time of 6.4 s, and a fading time of 4.7 s at 600 nm.

[0077] After voltage is applied to ethyl viologen, the photocharge can be transferred in the entire bipyridine plane of the radical cation viologen, so the ethyl viologen in this state has a large molar absorption coefficient, thus showing a deep blue-purple color. In addition, the alkyl chain of ethyl viologen is short, and the electron transfer rate is small, resulting in a fast response time.

[0078] Example 3: The difference between this example and Example 1 is that the electrochromic material described in step 2 is a mixture of 1,1'-dibenzyl-4,4'-bipyridyl dichloride (common name: benzyl viologen) and ferrocene; the concentration of 1,1'-dibenzyl-4,4'-bipyridyl dichloride in the electrochromic solution described in step 2 is 18mmol / L, the concentration of ferrocene is 15mmol / L, and the concentration of lithium perchlorate is 50mmol / L. Other steps and parameters are the same as those in Example 1.

[0079] The electrochromic device prepared in Example 3 was subjected to a performance test, and the test results are as follows:

[0080] The electrochromic device prepared in Example 3 has a fading voltage of 0 V, a coloring voltage of 1.1 V, a transparent state transmittance of 78.1%, a colored state transmittance of 22.5%, an optical modulation amplitude of 55.6%, a coloring time of 7.3 s, and a fading time of 6.5 s at 600 nm.

[0081] The coloring state of benzyl viologen has a higher transmittance, and the color change is not as significant as that of ethyl viologen and octyl viologen. This is due to the strong cation-π stacking force of the viologen cation and the electrostatic attraction of the phenyl group, which reduces the ability of photocharge transfer on 0-valent and +1-valent nitrogen atoms, reduces the molar absorption coefficient, and the coloring state of the material is not that deep. The reason for the longer response time is the interaction between the aromatic rings. Under the electrostatic attraction of the CH···π ring bond, the phenyl group tends to form an edge-to-face complex, while the face-to-face arrangement will cause electrostatic repulsion.

[0082] Example 4: This example is different from Example 1 in that the concentration of 1,1'-di-n-octyl-4,4'-dibromide pyridinium (common name: octyl viologen) in the electrochromic solution described in step 2 is 33 mmol / L, the concentration of ferrocene is 18 mmol / L, and the concentration of lithium perchlorate is 50 mmol / L. The other steps and parameters are the same as those in Example 1.

[0083] The electrochromic device prepared in this embodiment was tested for performance, and the test results are as follows:

[0084] The fading voltage of the electrochromic device prepared in Example 4 is 0V, the coloring voltage is 1.2V, the transparent state transmittance at 600nm is 75.5%, the colored state transmittance is 1.9%, and the optical modulation amplitude is 73.6%. The coloring time is 3.8s, and the fading time is 7.8s. This embodiment changes the ratio of octyl viologen and ferrocene in comparison with Example 1, and it is found that increasing octyl viologen and ferrocene causes the initial transmittance to decrease. This is because the viologen solution initially presents an orange-yellow color, so the more octyl viologen and ferrocene, the darker the color. The darker blue in the colored state is due to the fact that more octyl viologen obtains electronic color change.
