Description

Technical Field

[0001] This invention relates to the field of AR glasses display technology, specifically to an electrochromic coating AR glasses and an electrochromic method. Background Technology

[0002] With the continuous development of technology, augmented reality (AR) technology is gradually being applied to various fields, and AR glasses, as an important carrier of AR technology, have received widespread attention. Traditional AR glasses lenses usually use materials with fixed light transmittance, and their light transmittance cannot be adjusted according to the ambient light intensity or user needs.

[0003] In actual use, when the ambient light intensity is strong, such as in bright sunlight outdoors, excessive light will pass through the lens and enter the user's eyes, causing visual discomfort and even potentially damaging the eyes. When the ambient light intensity is weak, such as indoors or at night, the light transmittance of the lens may not be sufficient for the user to clearly see the surrounding environment and AR display content, affecting the user experience.

[0004] Currently, while some glasses products offer photochromic functionality, most utilize photochromic materials. These materials exhibit slow color-changing speeds, and the degree of color change is significantly affected by light intensity and duration, making rapid and precise color adjustment impossible. Furthermore, the color-changing range of photochromic materials is limited, failing to meet users' diverse needs for lens color in different scenarios. Therefore, developing AR glasses capable of rapid and precise color adjustment with a wide color-changing range is of significant practical importance. Summary of the Invention

[0005] To address the above problems, this invention provides an electrochromic coating AR glasses and an electrochromic method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrochromic AR glasses and an electrochromic method, comprising a glasses frame and a lens disposed on the glasses frame, characterized in that an electrochromic coating layer is attached to the surface of the lens, the electrochromic coating layer being composed of a multi-layer structure, comprising, from the side closest to the lens outward, an ion storage layer, an electrolyte layer, an electrochromic layer and a transparent conductive layer.

[0007] AR glasses also include a color-changing control circuit electrically connected to the transparent conductive layer. The color-changing control circuit is used to apply a voltage to the transparent conductive layer to control the color change of the electrochromic coating layer.

[0008] Preferably, the ion storage layer is made of nickel oxide or tungsten oxide, the electrolyte layer is made of lithium salt polymer electrolyte, the electrochromic layer is made of tungsten oxide or violet-based organic electrochromic material, and the transparent conductive layer is made of indium tin oxide or fluorine-doped tin oxide.

[0009] Preferably, the color-changing control circuit includes a power supply, a voltage regulation module, and a controller. The power supply provides electrical energy, the voltage regulation module is connected to the power supply and a transparent conductive layer for regulating the voltage applied to the transparent conductive layer, and the controller is connected to the voltage regulation module for controlling the operation of the voltage regulation module according to a preset program or an external input signal.

[0010] Preferably, the AR glasses also include an ambient light sensor, which is connected to the controller to detect the ambient light intensity and transmit the detection signal to the controller. The controller controls the voltage adjustment module to adjust the voltage applied to the transparent conductive layer according to the ambient light intensity signal, thereby controlling the automatic color change of the electrochromic coating layer.

[0011] Preferably, the AR glasses also include a user input module, which is connected to the controller. The user inputs a color-changing command through the user input module, and the controller controls the voltage adjustment module to adjust the voltage applied to the transparent conductive layer according to the color-changing command, thereby controlling the manual color change of the electrochromic coating layer.

[0012] An electrochromic coating AR glasses electrochromic method includes the following steps:

[0013] Step 1: Detect ambient light intensity or receive color-changing commands input by the user;

[0014] Step 2: Based on the detected ambient light intensity or the received color-changing command, apply a corresponding voltage to the transparent conductive layer of the electrochromic coating through the color-changing control circuit;

[0015] Step 3: Under the action of voltage, ions in the electrochromic coating migrate between the ion storage layer and the electrochromic layer, causing the color of the electrochromic layer to change, thus realizing the color change of the AR glasses lens.

[0016] Preferably, when the ambient light intensity is strong, a first preset voltage is applied to the transparent conductive layer through the color-changing control circuit, causing the electrochromic coating layer to turn dark; when the ambient light intensity is weak, a second preset voltage is applied to the transparent conductive layer through the color-changing control circuit, causing the electrochromic coating layer to turn light or transparent.

[0017] Preferably, when a color-changing command is received from the user, a specific voltage is applied to the transparent conductive layer through the color-changing control circuit according to the type of command input by the user, so that the electrochromic coating layer changes to the color specified by the user.

[0018] Preferably, during the voltage application process, the voltage applied to the transparent conductive layer is monitored and adjusted in real time by a voltage regulation module.

[0019] The beneficial effects of this invention are:

[0020] 1. By detecting ambient light intensity using an ambient light sensor and automatically adjusting the color of the electrochromic coating, the system provides a comfortable visual experience for users under different lighting conditions. When the ambient light is strong, the lens automatically turns dark to reduce the stimulation of strong light on the eyes; when the ambient light is weak, the lens automatically turns light or transparent to ensure that users can clearly see the surrounding environment and AR display content.

[0021] 2. In addition to the automatic color-changing function, users can also manually input color-changing commands through the user input module to achieve personalized adjustment of the lens color. Users can adjust the lenses to any color according to their preferences and actual needs to meet the usage requirements of different scenarios.

[0022] 3. By applying voltage to control ion migration, rapid color changes are achieved. Compared to traditional photochromic materials, the AR glasses of this invention change color much faster, switching colors instantly and improving ease of use.

[0023] 4. By selecting suitable electrochromic materials and adjusting the applied voltage, color changes within a wide range can be achieved in the electrochromic coating. Users can choose from various colors, from transparent to dark, to meet diverse application needs.

[0024] 5. During the color-changing process, the voltage applied to the transparent conductive layer is monitored and adjusted in real time by the voltage regulation module, ensuring the stability and uniformity of the color change of the electrochromic coating layer. This avoids problems such as uneven color or flickering caused by unstable voltage, thus improving the visual effect. Attached Figure Description

[0025] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used together with the embodiments of the invention to explain the invention, but do not constitute a limitation thereof. In the drawings:

[0026] Figure 1 This is a simplified structural diagram of the electrochromic coating AR glasses electrochromic method proposed in this invention. Detailed Implementation

[0027] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0028] Example 1: Reference Figure 1An electrochromic coating AR glasses and an electrochromic method are shown, including an eyeglass frame and a lens disposed on the eyeglass frame. The lens surface is characterized by having an electrochromic coating layer attached to it. The electrochromic coating layer is composed of a multi-layer structure, which includes an ion storage layer, an electrolyte layer, an electrochromic layer and a transparent conductive layer in sequence from the side closest to the lens outward.

[0029] AR glasses also include a color-changing control circuit electrically connected to the transparent conductive layer. The color-changing control circuit is used to apply a voltage to the transparent conductive layer to control the color change of the electrochromic coating layer.

[0030] In this embodiment, when the color of the AR glasses lens needs to be adjusted, the color-changing control circuit starts working, applying voltage to the lines electrically connected to the transparent conductive layer in the electrochromic coating layer. The voltage is transmitted to the transparent conductive layer and then acts on the entire electrochromic coating layer. Since the electrochromic coating layer includes an ion storage layer, an electrolyte layer, an electrochromic layer, and a transparent conductive layer in sequence from the side closest to the lens outward, under the action of voltage, ions in the ion storage layer migrate through the electrolyte layer to the electrochromic layer, causing a change in the optical properties of the electrochromic layer, thereby realizing the change of the color of the electrochromic coating layer. This process can flexibly adjust the color of the AR glasses lens according to different ambient light or user needs, improving visual comfort and user experience.

[0031] Regarding the materials used in the ion storage layer, this embodiment provides the following solution:

[0032] The ion storage layer is made of nickel oxide (NiO) or tungsten oxide (WO3), the electrolyte layer is made of lithium salt polymer electrolyte, the electrochromic layer is made of tungsten oxide (WO3) or violet-based organic electrochromic materials, and the transparent conductive layer is made of indium tin oxide (ITO) or fluorine-doped tin oxide (FTO).

[0033] In this embodiment, the color-changing control circuit is activated and applies voltage to the lines electrically connected to the transparent conductive layer (using indium tin oxide (ITO) or fluorine-doped tin oxide (FTO) material, which has good conductivity and transparency, can efficiently conduct current while ensuring light transmission) in the electrochromic coating layer. The voltage is transmitted to the transparent conductive layer and then acts on the entire electrochromic coating layer. At this time, ions in the ion storage layer (using nickel oxide (NiO) or tungsten oxide (WO3) material, which can store and release ions) migrate through the electrolyte layer (using lithium salt polymer electrolyte, which has good ion conductivity and allows ions to migrate smoothly) to the electrochromic layer (using tungsten oxide (WO3) or violet-based organic electrochromic material, which can change optical properties according to ion implantation) under voltage drive. After the ions enter the electrochromic layer, their optical properties change, thereby realizing the color change of the electrochromic coating layer. This process can flexibly adjust the color of the AR glasses lenses according to different ambient light conditions or user personalized needs, effectively improving visual comfort and user experience.

[0034] Regarding the color-changing control circuit, this embodiment provides the following solution:

[0035] The color-changing control circuit includes a power supply, a voltage regulation module, and a controller. The power supply provides electrical energy. The voltage regulation module is connected to the power supply and is used to regulate the voltage applied to the transparent conductive layer. The controller is connected to the voltage regulation module and is used to control the operation of the voltage regulation module according to a preset program or an external input signal.

[0036] In this embodiment, when the color of the AR glasses lens needs to be adjusted, the power supply starts working to provide power to the entire color-changing control circuit. The controller sends control commands to the voltage regulation module according to the preset program or the received external input signal. The voltage regulation module adjusts the power supplied by the power supply according to the control commands, and precisely controls the voltage applied to the transparent conductive layer. At this time, ions in the ion storage layer migrate to the electrochromic layer through the electrolyte layer under the voltage drive. After the ions enter the electrochromic layer, their optical properties change, thereby realizing the color change of the electrochromic coating layer. This process can flexibly and accurately adjust the color of the AR glasses lens according to different scenario needs and user personalized requirements, effectively improving visual comfort and user experience.

[0037] For collecting ambient light intensity for AR glasses, this embodiment provides the following solution:

[0038] AR glasses also include an ambient light sensor, which is connected to the controller to detect the ambient light intensity and transmit the detection signal to the controller. The controller controls the voltage adjustment module to adjust the voltage applied to the transparent conductive layer according to the ambient light intensity signal, thereby controlling the automatic color change of the electrochromic coating layer.

[0039] In this embodiment, during the use of AR glasses, the ambient light sensor continuously operates, detecting the light intensity of the surrounding environment in real time and quickly transmitting the detected light intensity signal to the connected controller. After receiving the signal, the controller sends precise control commands to the voltage regulation module according to the internally preset voltage regulation logic corresponding to the ambient light intensity. The voltage regulation module adjusts the power supplied by the power source according to the control commands, precisely controlling the voltage applied to the transparent conductive layer, thereby realizing the automatic change of the color of the electrochromic coating layer. This allows the AR glasses to automatically adjust the lens color according to the ambient light intensity without manual operation by the user, effectively improving visual comfort and ease of use in different lighting environments.

[0040] This embodiment provides a solution for manually controlling the color change of the electrochromic coating layer in AR glasses:

[0041] AR glasses also include a user input module, which is connected to the controller. Users input color-changing commands through the user input module, and the controller controls the voltage adjustment module to adjust the voltage applied to the transparent conductive layer according to the color-changing commands, thereby controlling the manual color change of the electrochromic coating layer.

[0042] In this embodiment, when the AR glasses are in normal use, on the one hand, the ambient light sensor continuously senses the intensity of the surrounding ambient light and transmits the light intensity signal to the controller, providing a data basis for automatic color changing; on the other hand, when the user has a specific lens color requirement, they can input a color-changing command through the user input module connected to the controller. After receiving the color-changing command from the user input module, the controller will send a corresponding control signal to the voltage adjustment module according to the color change requirement specified in the command, realizing the manual color change of the electrochromic coating layer. This process supports both automatic color changing according to ambient light and meets the user's need for manual personalized adjustment of lens color, greatly improving the visual comfort and usage flexibility of the AR glasses in different scenarios.

[0043] An electrochromic coating AR glasses electrochromic method includes the following steps:

[0044] Step 1: Detect ambient light intensity or receive color-changing commands input by the user;

[0045] Step 2: Based on the detected ambient light intensity or the received color-changing command, apply a corresponding voltage to the transparent conductive layer of the electrochromic coating through the color-changing control circuit;

[0046] When the ambient light intensity is strong, a first preset voltage is applied to the transparent conductive layer through the color-changing control circuit, causing the electrochromic coating layer to turn dark; when the ambient light intensity is weak, a second preset voltage is applied to the transparent conductive layer through the color-changing control circuit, causing the electrochromic coating layer to turn light or transparent.

[0047] When a color-changing command is received from the user, the color-changing control circuit applies a specific voltage to the transparent conductive layer according to the type of command input, so that the electrochromic coating layer changes to the color specified by the user.

[0048] During the voltage application process, the voltage applied to the transparent conductive layer is monitored and adjusted in real time by the voltage regulation module;

[0049] Step 3: Under the action of voltage, ions in the electrochromic coating migrate between the ion storage layer and the electrochromic layer, causing the color of the electrochromic layer to change, thus realizing the color change of the AR glasses lens.

[0050] This embodiment first activates the AR glasses, using an ambient light sensor to detect the intensity of surrounding ambient light while simultaneously keeping the user input module in a command-receiving state. This allows for the simultaneous detection of ambient light intensity and the receipt of user-inputted color-changing commands. Next, based on the detected ambient light intensity or the received color-changing command, a corresponding voltage is applied to the transparent conductive layer of the electrochromic coating using a color-changing control circuit. Specifically, if the detected ambient light intensity is strong, the controller in the color-changing control circuit issues a command, which, after adjustment by the voltage regulation module, applies a first preset voltage to the transparent conductive layer. Under this voltage, ions in the ion storage layer migrate through the electrolyte layer to the electrochromic layer, causing the electrochromic coating to darken. When the ambient light intensity is weak, the controller applies a second preset voltage to the transparent conductive layer through the voltage regulation module, causing ions to migrate from the ion storage layer to the electrochromic layer, turning the electrochromic coating darker. Reverse migration causes the electrochromic coating layer to become lighter or transparent. When a color-changing command is received from the user, the controller applies a specific voltage to the transparent conductive layer via the voltage regulation module, according to the command type, so that the electrochromic coating layer changes to the color specified by the user. Throughout the voltage application process, the voltage regulation module monitors the voltage on the transparent conductive layer in real time and adjusts it in a timely manner according to the actual situation to ensure that the voltage is stable and meets the requirements. Finally, under the action of the stable voltage, ions in the electrochromic coating layer continue to migrate between the ion storage layer and the electrochromic layer, thereby causing the color of the electrochromic layer to change accordingly, ultimately realizing the color change of the AR glasses lens. This method can both automatically adjust the lens color according to the ambient light and meet the user's manual personalized setting needs, effectively improving the visual comfort and user experience of AR glasses in different scenarios.

[0051] Regarding the practical application of the AR glasses of this invention, the electrochromic coating control method of this invention, compared with the display effect of existing AR glasses, provides the following advantages:

[0052] This invention controls AR glasses with an electrochromic coating using an electrochromic method, which can change the color of the coating under different light intensities in different scenarios. This reduces the light intensity entering the human eye from the outside of the AR glasses, thereby improving the display effect of the AR glasses screen and making the display effect brighter and clearer.

[0053] The brightness of the AR glasses display screen directly affects the display effect of the AR glasses. Taking the parameters of existing full-color AR glasses products as an example, when the brightness is 500 nits, and the typical light intensity in a normal indoor scene with lighting is 500 lux, a clear display effect can be achieved in an indoor lighting scene.

[0054] The relationship between eye-catching luminance (nits) and scene light intensity (lux) is as follows:

[0055] Formula 1

[0056] in: For eye-catching brightness, For the screen's own brightness, For screen surface reflectivity, This refers to the ambient light intensity.

[0057] According to Formula 1 above, it is known that... The brightness at eye level is 500 nits, based on the screen reflectivity. It is 0.05, indoors With a light intensity of 500 lux, the screen's brightness is calculated to be... It is 475 nits.

[0058] When the scene is outdoors on a sunny day, take the outdoor ambient light intensity. The screen reflectivity is 50,000 lux. The value remains at 0.05, and the screen's own brightness remains unchanged at 475 nits, allowing calculation of the required eye brightness on a sunny outdoor day. Calculation result one.

[0059] To achieve a clear viewing experience for the human eye, there are two approaches: first, increase the screen's own brightness; second, reduce the ambient light intensity. Since the full-color AR smart display glasses themselves cannot provide 2975 nits of light intensity, reducing the ambient light intensity is the only viable option. This invention controls the intensity of external light entering the AR glasses' display area by changing the color of the color-changing coating, thereby simulating the effect of reduced ambient light intensity and achieving a bright and clear screen display. The light absorption intensity of the color-changing coating is taken as... .

[0060] The formula for the in-eye brightness of the AR smart display glasses with a color-changing coating proposed in this invention is as follows: Formula 2:

[0061] Formula 2

[0062] Formula 3

[0063] in The value represents the actual ambient light intensity of the AR glasses after the electrochromic coating is added. T represents the transmittance of the electrochromic coating.

[0064] The electrochromic coating has a light transmittance T of up to 1%. According to formulas 2 and 3, under an outdoor ambient light intensity of 50,000 lux, the actual ambient light intensity of the AR glasses after adding the electrochromic coating is...

[0065]

[0066] At this time, the brightness of the AR display glasses entering the eye

[0067] This is the second calculation result.

[0068] The calculation result is that at a light intensity of 50,000 lux, the human eye needs to reach a brightness of 2,750 nits to see the display screen clearly.

[0069] The second calculation result is that the brightness of the display screen needs to reach 500 nits after adding the electrochromic coating, while the display brightness of existing AR glasses screens can already reach 500 nits.

[0070] The above discussion demonstrates that glasses with added electrochromic coating can achieve a bright and clear visual effect in sunny outdoor scenes without requiring the AR glasses screen itself to have extremely high display brightness. This greatly helps in controlling the power consumption and lifespan of AR glasses.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
