DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0039] The components of the embodiments of the present application generally described and shown in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] Hereinafter, the terms "include", "have", and their conjugations, which are used in the various embodiments of the present application, merely indicate the presence of the features, numbers, steps, operations, elements, components, or combinations thereof described in the specification, and do not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, elements, components, or combinations thereof.

[0041] Unless defined otherwise, all terms used herein (including technical terms and scientific terms) have the same meanings as those generally understood by those with ordinary knowledge in the field of the various embodiments of the present application. Such terms, as defined in generally used dictionaries, will be interpreted to have the same meanings as those in the context of relevant technology and will not be interpreted to have ideal or excessively formal meanings unless clearly defined in the various embodiments of the present application.

[0042] The above-described various embodiments of the present application will be described in detail with reference to the accompanying drawings. Figures 1 to 10 The various embodiments of the present application will be described in detail below. The following embodiments and features of the embodiments can be combined with each other unless there is a conflict.

[0043] In order to solve the problem that the general 3D glasses cannot adjust the light transmittance according to various application scenarios, the present application proposes a self-adjusting color-changing lens based on electrochromic film, which receives a control signal sent by an external controller, and changes the color of the electrochromic film in the lens according to the control signal to change the light transmittance of the lens. That is, by changing the brightness or color of the lens in real time, different stereoscopic imaging effects can be presented when watching 2D / 3D switching movies, and the light transmittance of the lens can also be adjusted according to the specific situation of the user to meet the personalized visual needs, providing a comfortable viewing experience.

[0044] Figure 1 The structural diagram of the self-adjusting color-changing lens 100 of some embodiments of the present application is shown. The self-adjusting color-changing lens 100 of the present application can be applied to smart glasses, head-mounted displays, and other self-adjusting color-changing glasses. Exemplarily, the self-adjusting color-changing lens includes a first glass 10, a second glass 20, and a plurality of electrochromic films 30 stacked between the first glass 10 and the second glass 20, the first glass 10 and the second glass 20 serving as transparent layers of the lens and protecting the films. Each electrochromic film 30 can be electrically connected with an external controller 261, the external controller 261 being configured to receive a switching signal sent by a player and send a control signal to the film to adjust the color change of each electrochromic film 30, so that the lens absorbs light of different wavelengths and has different imaging effects.

[0045] In an embodiment, the light transmittance of the lens refers to the amount of light of different wavelength corresponding to different color gamut, and the color gamut refers to the color range that the lens can display or process. The electrochromic film 30 obtains different colors by changing the red, green and blue color channels and superimposing them on each other. Each electrochromic film 30 allows different frequencies of red, green and blue light to pass through, and all can produce a common color gamut, but transmit light of different color bands, one of which can have a higher amount of light. The audience using the lens can feel the stereoscopic image displayed in an alternating rhythm. Each color band can also have the same amount of light, and the lens presents a clear flat image. For example, when a 3D image needs to be imaged, the light transmittance of the lens is lowered, and the lens is darkened to enhance the visual effect; when the lens needs to image a 2D image, the light transmittance of the lens is increased, and the lens is brightened to provide a clear visual experience. The user using the self-adjusting color-changing lens can adapt to 2D mode, 3D mode and 2D / 3D switching mode scenes.

[0046] In an embodiment, as shown in Figure 2 Each electrochromic film 30 includes a first conductive substrate layer, a first conductive layer, a functional layer, a second conductive layer and a second conductive substrate layer arranged in sequence, wherein the functional layers in the plurality of electrochromic films 30 respectively adopt one of red, green and blue electrochromic materials. For example, three electrochromic films are included, and the functional layers of the electrochromic films are respectively red, green and blue. Each electrochromic film 30 can be implemented independently, and the electrochromic films are fixed by an adhesive layer and can be arranged and combined in any way. The preparation method of the independently implemented electrochromic film 30 is simpler. The difference between the electrochromic films 30 is that the functional layer of each electrochromic film 30 adopts different color electrochromic materials to realize the adjustment of the transmittance of red, green and blue colors of the lens at the same time. The self-adjusting color-changing lens of the present application is based on the color mixing characteristics of three primary colors, and superimposes the electrochromic films 30 of three primary colors to ensure the light transmittance of the lens.

[0047] Further optionally, as shown in Figure 2As shown, the functional layers in adjacent electrochromic films 30 share a common conductive substrate layer. For example, multiple electrochromic films 30 include, sequentially disposed, a first conductive substrate layer 301, a first conductive layer 302, a first functional layer 303, a second conductive layer 304, a second conductive substrate layer 305, a third conductive layer 306, a second functional layer 307, a fourth conductive layer 308, a third conductive substrate layer 309, a fifth conductive layer 310, a third functional layer 311, a sixth conductive layer 312, and a fourth conductive substrate 313. By using a shared conductive substrate layer for each of the aforementioned electrochromic films 30, the overall thickness of the lens can be reduced. Because the use of a smaller conductive substrate layer is reduced, light absorption is decreased, and the overall light transmittance of the lens can be improved.

[0048] In one embodiment, such as Figure 3 As shown, multiple electrochromic films 30 are connected in parallel and then connected to a power supply 40. An external controller is electrically connected to the power supply 40. The external controller is used to control the power supply 40 to provide different voltages to each electrochromic film 30, so that each electrochromic film 30 has different light transmittance under different voltages. Each functional layer can undergo electrochemical oxidation-reduction reactions under different voltages, gaining or losing electrons, causing the color of the electrochromic material in each functional layer to change. For example, when each electrochromic film 30 is working in cycles, positive and negative voltages are applied between the conductive layers on both sides of each functional layer. Under the action of positive or reverse voltage, the electrochromic layer material of each functional layer can undergo an oxidation reaction, losing electrons and causing the material's color to change, so that the lens can change from transparent or light-colored to dark-colored. Under the action of reverse or positive voltage, the electrochromic layer material of each functional layer can undergo a reduction reaction, gaining electrons and causing the material's color to change, so that the lens can change from dark-colored back to transparent or light-colored. The three films work together to have different amounts of light entering different color wavelengths, thereby improving the three-dimensional effect of the display.

[0049] In another embodiment, the external controller refers to the exterior of the diaphragm. The external controller can control the color-changing speed and degree of each electrochromic diaphragm 30 by adjusting the magnitude and application time of the voltage. For example, when continuous coloring of the electrochromic diaphragm 30 is required, this can be achieved by continuously applying a constant coloring voltage.

[0050] In this embodiment, each functional layer has the same structure except that the color of the electrochromic material is different, so here we will take the structure of one of the functional layers as an example. For example, in one embodiment, the structure of the functional layer includes an electrochromic layer, an electrolyte layer, and an ion storage layer arranged in sequence, wherein the electrochromic layer is the layer where the color change reaction occurs; the electrolyte layer provides a channel for ion transmission when the electrochromic material undergoes a redox reaction, to maintain the charge balance of the entire system; the ion storage layer stores the corresponding counter ions when the electrochromic material undergoes a redox reaction, to maintain the charge balance of the entire system. The electrochromic layer materials of each electrochromic film are different, and the three films are divided into red, green, and blue electrochromic materials.

[0051] In another embodiment, as shown in Figure 4 each electrochromic film 30 is connected to a power supply 40, and a controller is used to control the voltage of each electrochromic film 30, respectively. By applying different voltages to electrochromic films 30 of different colors, selective transmission or absorption of light of different wavelengths is achieved. For example, in smart glasses, by enhancing or weakening specific wavelengths of light, the contrast and color saturation of the imaging of the glasses are improved.

[0052] For example, the two ends of the conductive layer in each electrochromic film 30 can be electrically connected to an external controller and a power supply 40 through a lead-out structure 50, which includes a first lead-out component and a second lead-out component arranged near the two ends of each electrochromic film 30, respectively. The first lead-out component and the second lead-out component are electrically connected to the positive and negative poles of the power supply, respectively, to form a loop between each electrochromic film 30 and the power supply 40, and the controller is connected to each film. The external controller controls the color change of each electrochromic film 30, thereby achieving selective transmission or absorption of light of different colors and wavelengths. Since each electrochromic film 30 can be connected in parallel to a power supply 40 or connected to a power supply 40 respectively, the lead-out structure 50 can be set according to different connection modes.

[0053] For example, in one embodiment, the edge region of the first conductive layer of each film is provided with a first bus bar 530, which is formed around the circumferential edge region of the first conductive layer; the first bus bar 530 provides a conductive effect, expands the contact area between the conductive layer and the first flexible substrate 520, and accelerates the color change speed of each electrochromic film. The edge region of the second conductive layer is provided with a second bus bar 531, which is wrapped around once. The first bus bar 530 and the second bus bar 531 are connected to the positive and negative poles of the power supply, respectively. As Figure 5As shown, when each electrochromic film 30 is connected in parallel to a power supply 40, the first lead-out component includes a first FPC 510, a first flexible substrate 520 and / or a plurality of first bus bars 530 disposed at the first end of each electrochromic film 30, and the second lead-out component includes a second FPC 511, a second flexible substrate 521 and / or a plurality of second bus bars 531 disposed at the second end of each electrochromic film 30. The first flexible substrate 520 connects the first bus bars 530 of each film in series to one substrate. The first flexible substrate 520 can be a flexible circuit board, and the first flexible substrate 520 is provided with a plurality of electrical contact points connected to the first bus bars 530. The corresponding second flexible substrate 521 has the same structure as the first flexible substrate 520, except that the second flexible substrate 521 is electrically connected to the second bus bars 531 of the edge region of the second conductive layer. The first end of the first flexible substrate 520 is disposed at one end of the first bus bar in each electrochromic film 30; one end of the first FPC 510 is connected to the second end of the first flexible substrate 520, and the other end of the first FPC passes out of the sealed curing area and is electrically connected to the controller and the power supply.

[0054] In an optional embodiment, the first bus bars 530 and the second bus bars 531 can be made of copper foil, silver wire, etc. The first flexible substrate 520 and the second flexible substrate 521 can be flexible printed circuit boards (FPCs).

[0055] For example, in another embodiment, as shown in Figure 6 when each electrochromic film 30 is connected in parallel to a power supply 40, the first lead-out component includes a first FPC 510, a first flexible substrate 520 and / or a plurality of first bus bars 530 disposed at the first end of each electrochromic film 30, and the second lead-out component includes a second FPC 511, a second flexible substrate 521 and / or a plurality of second bus bars 531 disposed at the second end of each electrochromic film 30. The first flexible substrate 520 connects the first bus bars 530 of each film in series to one substrate. The first flexible substrate 520 can be a flexible circuit board, and the first flexible substrate 520 is provided with a plurality of electrical contact points connected to the first bus bars 530. The corresponding second flexible substrate 521 has the same structure as the first flexible substrate 520, except that the second flexible substrate 521 is electrically connected to the second bus bars 531 of the edge region of the second conductive layer. The first end of the first flexible substrate 520 is disposed at one end of the first bus bar in each electrochromic film 30; one end of the first FPC 510 is connected to the second end of the first flexible substrate 520, and the other end of the first FPC passes out of the sealed curing area and is electrically connected to the controller and the power supply.

[0056] In an embodiment, as shown in Figure 7As shown, the self-adjusting photochromic lens further comprises a first optical adhesive layer 60 and a second optical adhesive layer 70; the first optical adhesive layer 60 is arranged between the first glass 10 and the electrochromic film 30 close to the first glass 10; the second optical adhesive layer 70 is arranged between the second glass 20 and the electrochromic film 30 close to the second glass 20. The optical adhesive layer can tightly bond the glass layer and the electrochromic film 30 together, prevent interlayer separation, ensure the stability and reliability of the lens, and has high transparency and low haze, which can ensure efficient transmission of light through the lens and reduce light loss, thereby improving the optical performance of the lens. The optical adhesive layer described above uses an optically transparent adhesive, such as OCA, PVB, etc.

[0057] In an embodiment, as shown in Figure 7 The self-adjusting photochromic lens 100 further comprises a curing area 80, which is located between the first glass 10 and the second glass 20 and forms a sealed film chamber with the first optical adhesive layer 60 and the second optical adhesive layer 70. The curing area 80 mainly functions as a sealing layer to protect the internal electrochromic films 30 from damage by the external environment, while ensuring the stability and long-term reliability of the lens.

[0058] Based on the self-adjusting photochromic lens 100 of the above embodiment, the present embodiment proposes a self-adjusting photochromic glasses 200, which may, for example, but not limited to, be smart glasses, head-mounted displays, driving glasses, smart light-sensitive photochromic glasses, and photochromic polarized sunglasses, etc. As shown in Figure 8 The self-adjusting photochromic glasses 200 comprise a first lens 210, a second lens 220, a frame 230, a nose pad 240, and a plurality of screws 250. The first lens 210 and the second lens 220 are arranged in the frame 230, the nose pad 240 is arranged below the first lens 210 and the second lens 220, and the screws 250 are used to fix various components of the glasses, including the frame 230, the nose pad 240, and the temples, etc. The first lens 210 is provided with a first contact 211 and a second contact 212 at both ends, and the first lens 210 is electrically connected to the power supply 40 through the first contact 211 and the second contact 212; the second lens 220 is provided with a third contact 221 and a fourth contact 222 at both ends, and the second lens 220 is electrically connected to the power supply 40 through the third contact 221 and the fourth contact 222. The first lens 210 and the second lens 220 use the self-adjusting photochromic lens 100 of the above embodiment. Since the self-adjusting photochromic glasses 200 use the self-adjusting photochromic lens 100 described above, it has all the advantages of the self-adjusting photochromic lens 100. It can be understood that the options in the above embodiments are also applicable to the present embodiment, so they will not be described again here.

[0059] In the embodiments of the present application, the first lens 210 and the second lens 220 each include three electrochromic films 30 that act on different color domains. The electrochromic films 30 in the first lens 210 and the second lens 220 that act on the same color domain have different wavelengths. The electrochromic films 30 with reasonable stacking combinations but different maximum absorption wavelengths are inserted into the first lens 210 and the second lens 220, respectively, to produce different imaging effects. The three electrochromic films 30 of each lens need to be tested for wavelengths, and at the same time, the brightness needs to be ensured to be lost to the maximum extent in the stacking (film thickness, distance). For example, in an embodiment, when the self-adjusting color-changing glasses 200 are used to watch 2D / 3D movies, the maximum absorption wavelength of the red electrochromic film of the first lens 210 is set to R1: 629 nm, the maximum absorption wavelength of the green electrochromic film is set to 532 nm, and the maximum absorption wavelength of the blue electrochromic film is set to 446 nm. The maximum absorption wavelength of the red electrochromic film of the second lens 220 is set to 615 nm, the maximum absorption wavelength of the green electrochromic film is set to 518 nm, and the maximum absorption wavelength of the blue electrochromic film is set to 432 nm. The wavelength settings of the electrochromic films 30 in the above first lens 210 and second lens 220 that act on the same color domain can ensure that the self-adjusting color-changing glasses 200 have stereoscopic imaging. In the stacking, the luminousity can be ensured to be not lost when the luminousity is high, and at the same time, the self-adjusting color-changing glasses 200 can also be ensured to present a colorless-neutral light gray state when the luminousity is low under the same working voltage, which can effectively reduce the visual differences such as color difference between the two eyes when watching.

[0060] It can be understood that when the luminousity of the lens is low, the lens will absorb more light, which can cause the light seen through the lens to be dark. Therefore, while ensuring the color of the lens, the luminousity of the lens also needs to be controlled to ensure that the light seen through the lens is a neutral light gray color. In 3D display using polarized light technology, the light is divided into two mutually perpendicular polarization directions, and enters the left and right eyes respectively, thereby generating a stereoscopic effect. In order to achieve this purpose, the first lens 210 and the second lens 220 of the self-adjusting color-changing glasses 200 need to adjust the light of different polarization directions respectively. Specifically, each electrochromic film 30 of the first lens 210 can be designed to have stronger absorption of horizontally polarized light, and each electrochromic film 30 of the second lens 220 can have stronger absorption of vertically polarized light. In this way, when the first lens 210 and the second lens 220 receive light of different polarization directions from the display, the color change of each electrochromic film 30 can be adjusted to make the images seen by the left and right eyes have different brightness and color, thereby generating a stereoscopic effect.

[0061] In an embodiment, as shown in FIG. 2, the self-adjusting color-changing glasses 200 include a first lens 210 and a second lens 220. The first lens 210 and the second lens 220 are connected to each other by a hinge 230, and the first lens 210 and the second lens 220 can be adjusted to be in a closed state or an open state by rotating the hinge 230. Figure 9As shown, each electrochromic film 30 in the first lens 210 and the second lens 220 can be collectively controlled, that is, the same voltage is applied. Each electrochromic film 30 in the first lens 210 and the second lens 220 is connected in parallel, and then connected to the positive and negative poles of the power supply 40. The above connection method is relatively simple, low in cost, and easy to implement in process. The power supply 40 can provide the same working voltage for the electrochromic films 30, and the first lens 210 and the second lens 220 can be discolored at the same working voltage, meeting the required light transmittance in different scenes.

[0062] In another embodiment, each electrochromic film 30 in the first lens 210 and the second lens 220 can be controlled individually to apply different or the same voltage to each film. Each electrochromic film 30 in the first lens 210 and the second lens 220 is connected to the power supply 40 through the first lead and the second lead, respectively, so as to realize individual control of each electrochromic film 30. By adjusting the voltage applied to each color electrochromic film 30, selective absorption or transmission of light of different wavelengths can be achieved, thereby achieving the effect of targeted light filtering. For example, in strong outdoor light, the voltage of each electrochromic film 30 in the first lens 210 and the second lens 220 is adjusted to adjust the discoloration degree of each electrochromic film 30, thereby obtaining different shades of brown or black to meet the requirements of different users for the degree of light blocking. It can be understood that the color and transparency of the first lens 210 and the second lens 220 can be automatically adjusted according to the intensity of the light, so as to maintain good visual effect in both strong light and weak light environments.

[0063] In an embodiment, as shown in Figure 10 The self-adjusting discoloring glasses 200 further include a first lens leg 260 and a second lens leg 270. The first lens leg 260 is rotationally connected to the frame 230, and the second lens leg 270 is rotationally connected to the frame 230. The first lens leg 260 is provided with a cavity accommodating a controller 261, and the second lens leg 270 is provided with a cavity accommodating a power supply 40. The power supply 40 is electrically connected to each electrochromic film 30 in the first lens 210 and the second lens 220, and provides the required voltage for each electrochromic film 30 to change the optical properties of the first lens 210 and the second lens 220. The power supply 40 is also electrically connected to the controller 261. The controller 261 can control the voltage provided by the power supply 40 for each electrochromic film 30 according to the actual use scene of the glasses, so as to change the light transmittance of the lenses in different use scenes.

[0064] In another embodiment, the first temple 260 is provided with a first temple cover 262, and the second temple 270 is provided with a second temple cover 271, which can be used to protect the electronic components and circuits inside the temples. The first ends of the first temple 260 and the second temple 270 are each provided with an anti-slip silica gel pad 272 to increase the friction between the glasses and the skin and prevent the glasses from slipping off.

[0065] In an optional embodiment, the controller 261 is a PCB control board, which can transmit the LED light source to the LED indicator 264 through the LED light guide column 263 to indicate the operation mode or working state of the glasses.

[0066] In another optional embodiment, the power supply 40 provided in the second temple 270 includes a battery 273, a charging panel 274, a magnet 275, and a charging PIN 276. The battery 273 is used to store electrical energy to provide power support for various glasses. The charging panel 274 is used to control the charging of the battery 273 and monitor the charging status of the battery 273. The magnet 275 and the charging PIN 276 are used in combination. The adsorption property of the magnet 275 and the conductive function of the charging PIN 276 make the charging process more convenient and efficient.

[0067] In an embodiment, the controller 261 includes a wireless signal receiver; the controller 261 is used to control the color change of the first lens 210 and the second lens 220 respectively according to the switching signal received by the wireless signal receiver to adjust the light transmittance of the first lens 210 and the second lens 220 respectively. For example, the self-adjusting color-changing glasses 200 of the present application can be matched with a Dolby Digital Cinema projector playing 2D and 3D movies when in use. In the 3D mode, in order to ensure that the images seen by the first lens 210 and the second lens 220 can be correctly separated and synthesized, the controller 261 controls the working voltage of the first lens 210 and the second lens 220 to make the first lens 210 and the second lens 220 have a certain light transmittance, improve the contrast and stereoscopic effect of the image, and make the user feel the alternating rhythm of displaying left and right stereoscopic images. When switching to the 2D mode, because all the audience see the same plane image without the requirement of stereoscopic effect, only single image information needs to be provided. When the wireless signal receiver receives the switching signal, the controller 261 controls the first lens 210 and the second lens 220 to have a higher light transmittance to provide a brighter visual experience.

[0068] In another embodiment, the self-adjusting color-changing glasses 200 of the present application can also provide a switching signal to the controller 261 through a manual button, so that the controller 261 provides a control signal to the lenses, and each electrochromic film 30 in the first lens 210 and the second lens 220 is charged or discharged at a set stable voltage under the control of the manual button, so as to switch different light transmittances and meet various application requirements.

[0069] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which shall be covered within the protection scope of the present application.
