TECHNICAL FIELD
[0001] The present application relates to the field of three-dimensional display, in particular to a shutter glasses and an image display system. BACKGROUND
[0002] Three-dimensional (3D) shutter glasses is a new type of video glasses, which mainly realizes 3D effect by improving the rapid refresh rate of the picture, and belongs to active 3D technology.
[0003] After the display device outputs a 3D image, the 3D shutter glasses realizes the corresponding image viewing of the left and right eyes in refresh synchronization, and the two eyes of the audience see different pictures switched rapidly, thereby realizing the stereoscopic visual effect.
[0004] The current 3D shutter glasses need to be used in correspondence with the display device, and the application range of the 3D shutter glasses is limited. UTILITY MODEL CONTENT
[0005] The present application provides a shutter glasses and an image display system. The application range of the shutter glasses is widened.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions.
[0007] In a first aspect, the present application provides a shutter glasses. The shutter glasses comprises a controller, a first lens and a second lens. The first lens comprises a first surface and a second surface arranged oppositely, and the second lens comprises a third surface and a fourth surface arranged oppositely. If the first surface is opposite to the left eye of a user, and the third surface is opposite to the right eye of the user, the controller controls the switching time sequence of the first lens to be a first time sequence, and controls the switching time sequence of the second lens to be a second time sequence. If the second surface is opposite to the right eye of the user, and the fourth surface is opposite to the left eye of the user, the controller controls the switching time sequence of the first lens to be the second time sequence, and controls the switching time sequence of the second lens to be the first time sequence.
[0008] In this way, the controller controls the switching time sequence of the lens opposite to the left eye of the user to be the same, which is the first time sequence. The switching time sequence of the lens opposite to the right eye of the user is the same, which is the second time sequence. The shutter glasses has at least two wearing states, i.e., the wearing state of the left eye opposite to the first lens or the wearing state of the right eye opposite to the first lens. By controlling the switching time sequence of the first lens and the second lens by the controller, the left eye can receive the left eye parallax image, and the right eye can receive the right eye parallax image. This is beneficial to widen the application range of the shutter glasses and reduce the use cost of the shutter glasses.
[0009] In combination with the first aspect, in some implementable manners, the first time sequence and the second time sequence are opposite. In this way, the controller can control the first time sequence and the second time sequence to be exchanged.
[0010] In conjunction with the first aspect, in some feasible ways, the first timing is used to indicate that, in chronological order, the first lens is in a light-transmitting state or in a light-blocking state.
[0011] Thus, the controller can control the light blocking or light transmission of the first lens according to the first timing sequence, so that the user can view the three-dimensional image.
[0012] In conjunction with the first aspect, in some feasible ways, the second timing includes: in chronological order, the second lens being either in a light-transmitting state or in a light-blocking state.
[0013] In conjunction with the first aspect, in some feasible embodiments, the shutter glasses further include a clamping member to which both the first and second lenses are connected.
[0014] In this way, shutter glasses can be connected to other wearable devices via a clip. For example, shutter glasses can be connected to eyeglasses such as prescription glasses, farsighted glasses, or sunglasses via a clip. Alternatively, shutter glasses can be detachably connected to head-mounted devices such as helmets or headphones via a clip.
[0015] In conjunction with the first aspect, in some feasible implementations, the shutter glasses further include: temples, a first connector, and a second connector. Both the first and second lenses are connected to the first connector, and the second connector is connected to the temples. The first and second connectors are detachably connected. Thus, the first surface of the first lens faces the user's left eye, or the second surface of the first lens faces the user's right eye. Furthermore, the shutter glasses can be used independently without needing to be connected to other wearable devices.
[0016] In conjunction with the first aspect, in some feasible implementations, the first connector includes a protrusion, and the second connector includes a slot; or, the first connector includes a slot, and the second connector includes a protrusion. In the first state, the shutter glasses are engaged with the protrusion, with a first side of the protrusion facing the temple; in the second state, the shutter glasses are engaged with the protrusion, with the first side of the protrusion facing away from the temple. Thus, in both the first and second states, the first connector and the second connector can be connected, facilitating user switching between the first and second states.
[0017] In conjunction with the first aspect, in some feasible ways, the protrusion is a square post and the slot is a square groove, or the protrusion is a circular post and the slot is a circular groove.
[0018] Thus, the first and second connectors have at least two insertion positions, facilitating user switching between the first and second states.
[0019] In conjunction with the first aspect, in some feasible embodiments, both the first connector and the second connector are magnetic structures. This allows for a detachable connection between the first and second connectors. Furthermore, the magnetic structure can connect in multiple directions. For example, both opposite surfaces of the first connector can be magnetically attracted to the second connector. In both the first and second states, the first and second connectors can be connected.
[0020] In conjunction with the first aspect, in some feasible embodiments, the first lens includes a first polarizer, a liquid crystal layer, and a second polarizer, wherein the first polarizer, the liquid crystal layer, and the second polarizer are arranged sequentially along a direction perpendicular to the first surface. The polarization directions of the first polarizer and the second polarizer are perpendicular to each other. The controller is connected to the liquid crystal layer and is used to control the liquid crystal layer to adjust the switching timing of the first lens to either the first timing or the second timing.
[0021] In this way, the controller can adjust the switching timing of the first lens by controlling the liquid crystal layer.
[0022] In conjunction with the first aspect, in some feasible embodiments, the second lens includes a first polarizer, a liquid crystal layer, and a second polarizer stacked sequentially, the first polarizer, the liquid crystal layer, and the second polarizer arranged in a direction perpendicular to the first surface. The polarization directions of the first polarizer and the second polarizer are perpendicular to each other. The controller is connected to the liquid crystal layer and is used to control the liquid crystal layer to adjust the switching timing of the second lens to the first timing or the second timing.
[0023] In conjunction with the first aspect, in some implementable embodiments, the shutter glasses further include a trigger. This trigger is signal-connected to the controller and transmits instructions to the controller indicating the switching timing of the first and second lenses.
[0024] In this way, the user can determine the relative position of the shutter glasses and the user's eyes, and then input commands based on this trigger state. The controller controls the opening and closing sequence of the shutter glasses.
[0025] In conjunction with the first aspect, in some feasible implementations, the shutter glasses further include: an acquisition device. Signal-connected to the controller, the acquisition device is used to acquire position information. If the position information indicates that the first surface is opposite the user's left eye, or the third surface is opposite the user's right eye; the controller controls the switching timing of the first lens to the first timing and controls the switching timing of the second lens to the second timing. If the position information indicates that the second surface is opposite the user's right eye, or the fourth surface is opposite the user's left eye; the controller controls the switching timing of the first lens to the second timing and controls the switching timing of the second lens to the first timing.
[0026] In this way, the shutter glasses can actively acquire position information, and the controller controls the opening and closing timing of the shutter glasses based on the position information. This allows the shutter glasses to open and close without the need for other components, enabling the user to view the correct 3D image.
[0027] In conjunction with the first aspect, in some possible implementations, the acquisition device includes: a distance sensor for detecting the distance from the first surface to the user's left eye. If the distance detected by the distance sensor is less than a first value, the controller controls the switching timing of the first lens to the first timing and controls the switching timing of the second lens to the second timing. If the distance detected by the distance sensor is greater than or equal to the first value, the controller controls the switching timing of the first lens to the second timing and controls the switching timing of the second lens to the first timing.
[0028] In this way, a distance sensor can be used to obtain the relative position of the shutter glasses and the user's eyes. The controller controls the opening and closing sequence of the shutter glasses based on the distance value detected by the distance sensor. This makes it more convenient to use.
[0029] In conjunction with the first aspect, in some implementable methods, the acquisition device includes: a temperature sensor for detecting the temperature of the first surface. If the temperature detected by the temperature sensor is greater than or equal to a first value, the controller controls the switching timing of the first lens to the first timing and controls the switching timing of the second lens to the second timing. If the temperature detected by the temperature sensor is less than the first value, the controller controls the switching timing of the first lens to the second timing and controls the switching timing of the second lens to the first timing.
[0030] In this way, a temperature sensor can be used to determine the relative position of the shutter glasses and the user's eye. The controller then uses the temperature value detected by the sensor to control the opening and closing sequence of the shutter glasses, making it more convenient to use.
[0031] In conjunction with the first aspect, in some implementable methods, the acquisition device includes: a capacitance sensor for detecting the capacitance of the first surface. If the capacitance detected by the capacitance sensor is greater than or equal to a first value, the controller controls the switching timing of the first lens to the first timing and controls the switching timing of the second lens to the second timing. If the capacitance detected by the capacitance sensor is less than the first value, the controller controls the switching timing of the first lens to the second timing and controls the switching timing of the second lens to the first timing.
[0032] In this way, a capacitive sensor can be used to obtain the relative position of the shutter glasses and the user's eye. The controller controls the opening and closing sequence of the shutter glasses based on the capacitance value detected by the capacitive sensor. This makes it more convenient to use.
[0033] Secondly, this application provides an image display system. The image display system includes a display device and any of the shutter glasses provided in the first aspect. The display device is used to output image light. The shutter glasses are used to receive the image light.
[0034] Because of its expanded applicability, shutter glasses can be used with different types of film sources. Furthermore, shutter glasses can be used with image light display devices that emit image light in a first polarization direction and those that emit image light in a second polarization direction. Shutter glasses offer wide applicability and low operating costs, thus reducing the overall cost of image display systems.
[0035] In conjunction with the second aspect, in some implementable methods, the display device includes a display screen and a processing chip. The processing chip is signal-connected to the controller. The processing chip is used to: adjust the display screen to output a first image based on the switching timing of the first lens as the first timing. The processing chip is also used to: adjust the display screen to output a second image based on the switching timing of the first lens as the second timing. Wherein, the playback timing of the left-eye parallax image and the right-eye parallax image in the first image is different from the playback timing of the left-eye parallax image and the right-eye parallax image in the second image.
[0036] Regarding the beneficial effects of the second aspect, please refer to the description of any optional implementation method in the first aspect, which will not be repeated here. Based on the implementation methods provided in the above aspects, this application can also be further combined to provide more implementation methods. Attached Figure Description

Detailed Implementation
[0047] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.
[0048] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0049] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.
[0050] Figure 1 This is a schematic diagram of the structure of an image display system 10 provided in an embodiment of this application. Please refer to... Figure 1 The image display system 10 includes a display device 20 and shutter glasses 100. The display device 20 is used to output image light, and the shutter glasses 100 is used to receive image light. The user views the image displayed on the display device 20 through the shutter glasses 100, and the user can observe a three-dimensional image.
[0051] This application does not limit the type of display device 20. For example, it can be a television, tablet computer, laptop computer, PDA, mobile internet device (MID), wearable device (e.g., watch, bracelet, smart helmet, etc.), virtual reality (VR) device, augmented reality (AR) device, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc.
[0052] For example, the shutter glasses 100 and the display device 20 are independently configured, but are communicatively connected. For instance, the shutter glasses 100 and the display device 20 are located on the same local area network (LAN) and interconnected through this LAN. For example, in some possible scenarios, the shutter glasses 100 and the display device 20 may use optical communication technology to establish a communication connection with a radio access network (RAN) and access a server.
[0053] Alternatively, the shutter glasses 100 and the display device 20 can be interconnected via Bluetooth, infrared light, star flash, microwave, or other means. Alternatively, the shutter glasses 100 and the display device 20 can be connected via optical signal lines or electrical signal lines.
[0054] In some embodiments, the shutter glasses 100 and the display device 20 can be interconnected via network devices in a Fiber to the Room (FTTR) network. FTTR refers to a networking technology that uses fiber optic cables instead of network cables, laying fiber optic cables to every room, deploying optical network devices to interconnect with a home gateway, and combining wireless technology to ensure whole-house network coverage.
[0055] In embodiments of this application, the shutter glasses 100 and the display device 20 can be interconnected via optical network devices in an FTTR.
[0056] For example, the display device 20 includes a display screen 010 and a processing chip 011, which are electrically connected. The processing chip 011 sends image information to the display screen 010, and the display screen 010 receives the image information and outputs image light based on the received image information. The image light output by the display screen 010 is polarized light. After the viewer passes through the image light via the shutter glasses 100, and the viewer's brain perceives the parallax images of the right and left eyes, the viewer can view a three-dimensional image.
[0057] Typically, the processing chip 011 sends image information to the display screen 010. This image information carries one of two source image types: The first type consists of frames where the first frame is a left-eye parallax image, the second frame is a right-eye parallax image, the third frame is a left-eye parallax image, the fourth frame is a right-eye parallax image, and so on. The second type consists of frames where the first frame is a right-eye parallax image, the second frame is a left-eye parallax image, the third frame is a right-eye parallax image, the fourth frame is a left-eye parallax image, and so on.
[0058] The arrangement order of the left-eye and right-eye parallax images in the first type of video source is different from that in the second type of video source. In some embodiments, the arrangement order of the left-eye and right-eye parallax images can also be referred to as the playback sequence of the left-eye and right-eye parallax images.
[0059] In other words, the playback timing of the left-eye parallax image and the right-eye parallax image of the two video sources is different.
[0060] When the processing chip 011 sends different types of video sources to the display screen 010, the switching timing of the shutter glasses 100 needs to be different so that the viewer can see the correct 3D image.
[0061] For example, the processing chip 011 is signal-connected to the shutter glasses 100. The processing chip 011 adjusts the playback timing of the images sent by the display screen 010 according to the wearing status.
[0062] The shutter glasses 100 include two lenses, a first lens 110 and a second lens 120. When a viewer uses the shutter glasses 100, the first lens 110 and the second lens 120 are respectively positioned opposite one of the viewer's eyes. Figure 1 In the example, the first lens 110 is opposite to the viewer's left eye, and the second lens 120 is opposite to the viewer's right eye. The viewer's left eye receives the image light output from the display screen 010 through the first lens 110, and the viewer's right eye receives the image light output from the display screen 010 through the second lens 120.
[0063] During the image light output by display screen 010, the switching timing of the first lens 110 and the second lens 120 are not synchronized. For example, when display screen 010 outputs image light, and the first frame of the image is displayed, the first lens 110 is on and the second lens 120 is off. The viewer's left eye can receive the image light, but the viewer's right eye cannot. The viewer's left eye can see the left-eye parallax image. When the second frame of the image is displayed, the first lens 110 is off and the second lens 120 is on. The viewer's right eye can receive the image light, but the viewer's left eye cannot. The viewer's right eye can see the right-eye parallax image.
[0064] The aforementioned open state of the first lens 110 can also be referred to as the light-transmitting state of the first lens 110, and the aforementioned closed state of the first lens 110 can also be referred to as the light-blocking state of the first lens 110. The same applies to the second lens 120.
[0065] The aforementioned "open" state of the first lens 110 means that the polarized light output from the display screen 010 can pass through the first lens 110 and reach the viewer's left eye. The aforementioned "closed" state of the first lens 110 means that the polarized light output from the display screen 010 is blocked by the first lens 110, and the polarized light output from the display screen 010 cannot reach the viewer's left eye. During the process of the image light output from the display screen 010, the first lens 110 continuously switches between the open and closed states. In the first time period, the first lens 110 is open; in the second time period, the first lens 110 is closed; in the third time period, the first lens 110 is open, and so on. The first, second, and third time periods are consecutive. The aforementioned continuous switching between the open and closed states of the first lens 110 in different time periods can be referred to as the switching sequence of the first lens 110.
[0066] The switching sequence of the second lens 120 is the same, and will not be repeated here.
[0067] For different displays 010, the polarization direction of the output image light may be different. For example, some types of displays 010 output image light with a first polarization direction, while others output image light with a second polarization direction, and the first and second polarization directions are perpendicular to each other.
[0068] The first lens 110 can switch from an open state to a closed state by folding polarized light in a first polarization direction. Therefore, the first lens 110 is suitable for display screens 010 where the polarization direction of the output image light is the first polarization direction. If the polarization direction of the output image light is the second polarization direction, the first lens 110 cannot switch from an open state to a closed state because it intercepts polarized light in the first polarization direction. The same applies to the second lens 120.
[0069] In the embodiments of this application, the shutter glasses 100 can be adapted to the display screen 010 that outputs image light in a first polarization direction. The shutter glasses 100 can also be adapted to the display screen 010 that outputs image light in a first polarization direction.
[0070] In addition, the shutter glasses 100 provided in this application embodiment can be adapted to the two types of film sources mentioned above, which helps to broaden the scope of application of the shutter glasses 100 and reduce the cost of using the shutter glasses 100.
[0071] Figure 2 This is a schematic diagram of the structure of a shutter glasses 100 provided in an embodiment of this application. Please refer to [link / reference]. Figure 2 The shutter glasses 100 include a first lens 110, a second lens 120, and a controller 130. Both the first lens 110 and the second lens 120 are connected to the controller 130.
[0072] The first lens 110 includes a first surface 001 and a second surface 002 arranged opposite to each other, and the second lens 120 includes a third surface 003 and a fourth surface 004 arranged opposite to each other. Both the first lens 110 and the second lens 120 are signal connected to the controller 130.
[0073] If the first surface 001 is opposite to the user's left eye and the third surface 003 is opposite to the user's right eye, the controller 130 controls the switching sequence of the first lens 110 to be the first timing sequence, and the controller 130 controls the switching sequence of the second lens 120 to be the second timing sequence.
[0074] In the embodiments of this application, the state in which "the first surface 001 is opposite to the user's left eye and the third surface 003 is opposite to the user's right eye" is defined as the first wearing state of the shutter glasses 100.
[0075] In other words, in the first wearing state, the first surface 001 is closer to the user's left eye than the second surface 002. When the first lens 110 is in a light-transmitting state, the display screen 010 (e.g.) Figure 1The image light output from the display screen 010 (as shown) enters the first lens 110 through the second surface 002, and then is transmitted to the user's left eye through the first surface 001. In the first wearing state, the third surface 003 is closer to the user's right eye than the fourth surface 004. When the second lens 120 is in a light-transmitting state, the display screen 010 (as shown)... Figure 1 The image light output (as shown) enters the second lens 120 through the fourth surface 004, and is then transmitted to the user's right eye through the third surface 003.
[0076] During use, the controller 130 and the processing chip 011 (such as...) Figure 1 (As shown) signal connection. Processing chip 011 is used to adjust the display screen output of a first image based on the switching timing of the first lens as the first timing. The processing chip is also used to: adjust the display screen output of a second image based on the switching timing of the first lens as the second timing. The playback timing of the left-eye parallax image and the right-eye parallax image in the first image is different from the playback timing of the left-eye parallax image and the right-eye parallax image in the second image.
[0077] In other words, in the first wearable state, the processing chip adjusts the image output by the display screen to a first image, and the playback timing of this first image is the first playback timing. In the second wearable state, the processing chip adjusts the image output by the display screen to a second image, and the playback timing of this second image is the second playback timing.
[0078] The first playback sequence includes two characters arranged in the order of the playback frames: character one indicates that the image in that frame is a left-eye parallax image, and character two indicates that the image in that frame is a right-eye parallax image. The second playback sequence is similar.
[0079] Figure 2 The example shows a schematic diagram of the shutter glasses 100 in the first wearing state.
[0080] Figure 3 for Figure 2 A schematic diagram of the shutter glasses 100 in the second wearing state. Please refer to [link / reference]. Figure 3 If the second surface 002 is opposite to the user's right eye, and the fourth surface 004 is opposite to the user's left eye, the controller 130 controls the switching sequence of the first lens 110 to be the second timing sequence, and the controller 130 controls the switching sequence of the second lens 120 to be the first timing sequence.
[0081] In the embodiments of this application, the state in which "the second surface 002 is opposite to the user's right eye and the fourth surface 004 is opposite to the user's left eye" is defined as the second wearing state of the shutter glasses 100.
[0082] In other words, in the second wearing state, the second surface 002 is closer to the user's right eye than the first surface 001. When the first lens 110 is in a light-transmitting state, the display screen 010 (e.g.) Figure 1 The image light output from the display screen 010 (as shown) enters the first lens 110 through the first surface 001, and then is transmitted to the user's right eye through the second surface 002. In the first wearing state, the fourth surface 004 is closer to the user's left eye than the third surface 003. When the second lens 120 is in a light-transmitting state, the display screen 010 (as shown)... Figure 1 The image light output (as shown) enters the second lens 120 through the third surface 003 and is then transmitted to the user's left eye through the fourth surface 004.
[0083] Taking the first lens 110 as an example, the first lens 110 is based on the display screen 010 (e.g. Figure 1 The polarization direction of the output image light (as shown) allows it to pass through or block the image light. When the image light is transmitted to the first lens 110, the switching between the blocking state and the transmitting state of the first lens 110 is related to the polarization direction of the image light.
[0084] In the same wearing state, if the polarization direction of the image light changes, the first lens 110 will not be able to switch between transmitting or blocking the image light.
[0085] In the embodiments of this application, the shutter glasses 100 has two wearing states, and the orientation of the first surface 001 of the first lens 110 is different in the two wearing states. The controller 130 can control the switching timing of the first lens 110 and the second lens 120 of the shutter glasses 100 in different wearing states. The switching timing of the lens opposite the user's left eye is the same in both wearing states, which is the first timing. The switching timing of the lens opposite the user's right eye is the same in both wearing states, which is the second timing. In both wearing states, the left eye can receive the left-eye parallax image, and the right eye can receive the right-eye parallax image.
[0086] In the embodiments of this application, the switching timing of the first lens 110 and the second lens 120 is controlled by the controller 130, enabling the shutter glasses 100 to be used with two types of film sources. This helps to broaden the applicability of the shutter glasses 100 and reduce the cost of using the shutter glasses 100.
[0087] For example, the first timing sequence is used to indicate that, in chronological order, the first lens 110 is in a light-transmitting state or a light-blocking state. Thus, the controller can control the light-blocking or light-transmitting state of the first lens in the first wearing state according to the first timing sequence, thereby allowing the user to view a three-dimensional image.
[0088] For example, the states of the first lens 110 are arranged sequentially according to time as follows: light-transmitting state, light-blocking state, light-transmitting state, light-blocking state, light-transmitting state, light-blocking state, etc. The aforementioned two states arranged sequentially according to time can be referred to as the first time sequence. The controller controls the state of the first lens 110 according to the aforementioned first time sequence, so that the user's left eye can receive the beam of light of the left eye parallax image.
[0089] The switching sequence for the second lens 120 is the same.
[0090] In some embodiments of this application, the first timing sequence and the second timing sequence are reversed. For example, the arrangement order of the first lens 110 in the first timing sequence being in a light-transmitting state or a light-blocking state is reversed in the second timing sequence. In one embodiment, the first lens 110 is in a light-transmitting state, and the second lens 120 is in a light-blocking state. In another embodiment, the first lens 110 is in a light-blocking state, and the second lens 120 is in a light-transmitting state.
[0091] For example, in the first wearable state, the switching sequence of the first lens 110 is a first timing sequence, and the switching sequence of the second lens 120 is a second timing sequence. In the first wearable state, the duration of the light-transmitting state of the first lens 110 in the first timing sequence is equal to the duration of the light-blocking state of the second lens 120. The duration of the light-blocking state of the first lens 110 in the first timing sequence is equal to the duration of the light-transmitting state of the second lens 120.
[0092] Figure 4 This is a schematic diagram of the structure of the first lens 110 provided in an embodiment of this application. Please refer to... Figure 4 The first lens 110 includes a first polarizer 111, a liquid crystal (LC) layer 113, and a second polarizer 112, which are sequentially stacked along a line perpendicular to the first surface 001. The liquid crystal layer 113 is located between the first polarizer 111 and the second polarizer 112. The polarization directions of the first polarizer 111 and the second polarizer 112 are perpendicular to each other.
[0093] The controller 130 is used to control the liquid crystal layer 113 to control the switching timing of the first lens 110 to be either the first timing or the second timing.
[0094] Because liquid crystal molecules have dielectric anisotropy, when a voltage is applied to the liquid crystal molecules, the liquid crystal molecules will rearrange along the direction of the electric field lines.
[0095] This application does not limit the type of liquid crystal molecules. For example, the liquid crystal molecules can be polymer dispersed liquid crystal (PDLC), polymer network liquid crystal (PNLC), or polymer stabilized liquid crystal (PSLC), etc. The aforementioned liquid crystals exhibit anisotropy towards polarized light with different polarization directions.
[0096] For example, the first polarizer 111 and the liquid crystal layer 113 are connected by a transparent adhesive layer. The second polarizer 112 and the liquid crystal layer 113 are connected by a transparent adhesive layer.
[0097] In some embodiments of this application, a first electrode 114 and a second electrode 115 are respectively disposed on two opposite surfaces of the liquid crystal layer 113. The first electrode 114 is located between the first polarizer 111 and the liquid crystal layer 113. The second electrode 115 is located between the second polarizer 112 and the liquid crystal layer 113.
[0098] For example, the first electrode 114 and the second electrode 115 are made of transparent conductive materials, such as indium tin oxide (ITO).
[0099] Both the first electrode 114 and the second electrode 115 are electrically connected to the controller 130. The controller 130 is used to control the potential difference between the first electrode 114 and the second electrode 115, thereby controlling the director of the liquid crystal molecules. This controls the effect of the liquid crystal molecules on polarized light.
[0100] For example, when the potential difference between the first electrode 114 and the second electrode 115 is a first voltage and the direction of the liquid crystal molecule is a first direction, the liquid crystal layer 113 deflects the polarized light in the first polarization direction into polarized light in the second polarization direction, and the first polarization direction and the second polarization direction are perpendicular to each other.
[0101] When the potential difference between the first electrode 114 and the second electrode 115 is the second voltage, and the direction vector of the liquid crystal molecules is the first direction, the liquid crystal layer 113 does not change the polarization direction of the polarized light in the first polarization direction.
[0102] Thus, the controller 130 controls the first lens 110 to transmit or block light by controlling the potential difference between the first electrode 114 and the second electrode 115.
[0103] As described above, in the first wearing state, the first surface 001 is opposite to the user's left eye. In the second wearing state, the second surface 002 is opposite to the user's right eye.
[0104] When in the second wearable state, the image light is transmitted from the first polarizer 111 to the liquid crystal layer 113, and the controller 130 controls the liquid crystal layer 113 to control whether the image light enters the user's right eye through the second polarizer 112.
[0105] When in the first wearable state, the image light is transmitted from the second polarizer 112 to the liquid crystal layer 113. The controller 130 controls the liquid crystal layer 113 to control whether the image light passes through the first polarizer 111 and enters the user's right eye.
[0106] Clearly, in both of the aforementioned wearing states, the image light needs to enter the liquid crystal layer 113. The controller 130 controls the liquid crystal layer 113, thereby controlling whether the first lens 110 is in a light-transmitting state or a light-blocking state. Furthermore, the light beam's transmission direction within the first lens 110 is opposite in the two wearing states. In the first wearing state, the light beam is transmitted to the liquid crystal layer 113 through the first polarizer 111 with a first polarization direction. In the second wearing state, the light beam is transmitted to the liquid crystal layer 113 through the second polarizer 112 with a second polarization direction.
[0107] Thus, when the polarization direction of the image light is the first polarization direction, the second wearing state is adopted to prevent the first polarizer 111 from blocking the image light and preventing it from being transmitted to the liquid crystal layer 113. When the polarization direction of the image light is the second polarization direction, the first wearing state is adopted to prevent the second polarizer 112 from blocking the image light and preventing it from being transmitted to the liquid crystal layer 113. In other words, the shutter glasses 100 provided in this application embodiment is applicable to displays where the polarization direction of the output image light is the first polarization direction, and also applicable to displays where the polarization direction of the output image light is the second polarization direction. This increases the applicability of the shutter glasses 100 and reduces the usage cost of the shutter glasses 100.
[0108] For example, Figure 2 In the example, the polarization direction of the image light is the first polarization direction. Figure 3 In the example, the polarization direction of the image light is the second polarization direction.
[0109] During use, users can determine whether the wearing status is correct by observing whether light passes through the first lens 110 or the second lens 120.
[0110] For example, in an embodiment where the polarization direction of the image light is the first polarization direction, if the shutter glasses 100 are in a first wearing state, for the first lens 110, the image light needs to be transmitted from the second surface 002 to the first lens 110, and then from the first surface 001 to the left eye. Since the polarization direction of the second polarizer 112 is perpendicular to the polarization direction of the image light, the second polarizer will block the image light. The image light will not be able to enter the liquid crystal layer 113, and in this wearing state, the image light will not be able to pass through the first lens 110. The user's left eye cannot receive the image light. Similarly, the image light will not be able to pass through the second lens 120, and the user's right eye cannot receive the image light either.
[0111] In the embodiment where the polarization direction of the image light is the first polarization direction, if the shutter glasses 100 is in the second wearing state, for the first lens 110, the image light needs to be transmitted from the first surface 001 to the first lens 110, and then from the second surface 002 to the right eye. Since the polarization direction of the first polarizer 111 is parallel to the polarization direction of the image light, the first polarizer will transmit the image light. The image light can enter the liquid crystal layer 113. In this wearing state, when the liquid crystal layer 113 is in the open state, the user's right eye can receive the image light. Similarly, when the liquid crystal layer 113 is in the open state, the user's left eye can also receive the image light.
[0112] In summary, in the embodiment where the polarization direction of the image light is the first polarization direction, if neither the user's left nor right eyes can receive the image light, or if the brightness of the image light received by both eyes is weak, it indicates that the user's current wearing status is incorrect, and the user needs to select another wearing status. If the user's left eye can receive the image light for a portion of the time, it indicates that the user's current wearing status is correct.
[0113] The same applies to the embodiment where the polarization direction of the image light is the second polarization direction.
[0114] In some embodiments of this application, the wearing status of shutter glasses can be selected by detecting the polarization direction of the image light emitted from the display screen 010.
[0115] In this application, the controller 130 controls the switching timing of the first lens 110 and the second lens 120 according to the state of the shutter glasses 100.
[0116] Figure 5 This is a schematic diagram of another shutter glasses 100 provided in an embodiment of this application. Please refer to... Figure 5In some embodiments, the shutter glasses 100 may further include a trigger 140, which is signal-connected to the controller 130. For example, the trigger 140 is electrically connected to the controller 130, or the trigger 140 and the controller 130 are located on the same local area network and interconnected. The trigger 140 transmits instructions to the controller 130. The instructions are used to indicate the switching timing of the first lens 110 and the second lens 120.
[0117] In this way, the user can determine the wearing status of the shutter glasses 100, and then input a command based on the trigger status via the trigger 140. The controller 130 controls the opening and closing timing of the shutter glasses 100.
[0118] This application does not limit the type of trigger 140. For example, trigger 140 may be a keyboard, a slide switch, or a button. In some embodiments, trigger 140 may be a touch control that can be integrated onto the first lens 110.
[0119] The trigger 140 can be connected to the first lens 110 or the second lens 120. For example, the trigger 140 can be directly connected to the first lens 110, or the trigger 140 can be indirectly connected to the first lens 110 through a bracket or the like.
[0120] In some embodiments of this application, the shutter glasses 100 can actively acquire the state of the shutter glasses 100.
[0121] Figure 6 A schematic diagram of another shutter glasses 100 provided in an embodiment of this application. Please refer to... Figure 6 The shutter glasses 100 may also include an acquisition device 150.
[0122] The acquisition device 150 is signal-connected to the controller 130, and the acquisition device 150 is used to acquire position information. If the position information indicates that the first surface 001 is opposite the user's left eye, or the third surface 003 (e.g., ...) Figure 3 (As shown) is opposite to the user's right eye. The controller 130 controls the switching timing of the first lens 110 to the first timing, and controls the switching timing of the second lens 120 to the second timing. If the position information indicates: the second surface 002 (as shown) is opposite to the user's right eye. Figure 3 (as shown) is opposite to the user's right eye, or, the fourth surface 004 (as shown) Figure 3 (As shown) is opposite to the user's left eye; the controller 130 controls the switching sequence of the first lens 110 to the second timing sequence, and controls the switching sequence of the second lens 120 to the first timing sequence.
[0123] In this way, the shutter glasses 100 can actively acquire position information, and the controller 130 controls the opening and closing timing of the shutter glasses 100 based on the position information. The opening and closing timing of the shutter glasses 100 can be controlled without the aid of other devices, allowing the user to view the correct 3D image.
[0124] In the embodiments of this application, the acquisition device 150 has various types.
[0125] In some embodiments, the acquisition device 150 includes a distance sensor for detecting the distance from the first surface 001 to the user's left eye. If the distance detected by the distance sensor is less than a first value, the controller 130 controls the shutter glasses 100 to be in the first wearing state. If the distance detected by the distance sensor is greater than or equal to the first value, the controller 130 controls the shutter glasses 100 to be in the second wearing state.
[0126] In other words, if the distance between the first surface 001 and the user's left eye is small, the shutter glasses 100 are in the first wearing state, and the controller 130 controls the switching sequence of the first lens 110 to be the first timing sequence and the switching sequence of the second lens 120 to be the second timing sequence. Conversely, if the distance between the first surface 001 and the user's left eye is large, the shutter glasses 100 are in the second wearing state, and the controller 130 controls the switching sequence of the first lens 110 to be the second timing sequence and the switching sequence of the second lens 120 to be the first timing sequence.
[0127] Thus, the wearing status of the shutter glasses 100 can be obtained using a distance sensor. The controller controls the switching timing based on the current wearing status of the shutter glasses 100.
[0128] Furthermore, the distance from the first surface 001 to the user's left eye can be detected by detecting the distance from the first surface 001 to the face, and then obtaining the distance from the first surface 001 to the user's left eye. In other words, the distance sensor can detect the distance from the first surface 001 to the face.
[0129] For example, the first value detected by the aforementioned distance sensor can be set according to the size and shape of the shutter glasses 100.
[0130] In some embodiments of this application, a distance sensor can be used to detect the distance from the third surface 003 to the user's right eye. If the distance detected by the distance sensor is less than a second value, the controller 130 controls the switching timing of the shutter glasses 100 to be the switching timing corresponding to the first wearing state. If the distance detected by the distance sensor is greater than or equal to the second value, the controller 130 controls the switching timing of the shutter glasses 100 to be the switching timing corresponding to the second wearing state.
[0131] In other words, the controller 130 can control the opening and closing timing of the shutter glasses 100 based on the distance sensor detecting the distance from the third surface 003 to the user's right eye, or the distance from the first surface 001 to the user's left eye.
[0132] Alternatively, in some embodiments of this application, a distance sensor can be used to detect the second surface 002 (e.g., Figure 3 The distance from the distance sensor to the user's left eye is shown. If the distance detected by the distance sensor is greater than or equal to a third value, the controller 130 controls the switching timing of the first lens 110 to the first timing and controls the switching timing of the second lens 120 to the second timing. If the distance detected by the distance sensor is less than the third value, the controller 130 controls the switching timing of the first lens 110 to the second timing and controls the switching timing of the second lens 120 to the first timing.
[0133] In some embodiments, a distance sensor can be used to detect a fourth surface 004 (such as...). Figure 3 The distance from the distance sensor to the user's left eye is shown. If the distance detected by the distance sensor is greater than or equal to the fourth value, the controller 130 controls the switching timing of the shutter glasses 100 to be the switching timing corresponding to the first wearing state. If the distance detected by the distance sensor is less than the fourth value, the controller 130 controls the switching timing of the shutter glasses 100 to be the switching timing corresponding to the second wearing state.
[0134] In some embodiments of this application, the acquisition device 150 includes a temperature sensor. The temperature sensor is used to detect the temperature of the first surface 001. If the temperature detected by the temperature sensor is greater than or equal to a first value, the controller controls the switching timing of the first lens 110 to the first timing and controls the switching timing of the second lens 120 to the second timing. If the temperature detected by the temperature sensor is less than the first value, the controller controls the switching timing of the first lens 110 to the second timing and controls the switching timing of the second lens 120 to the first timing.
[0135] In the first wearing state, the first surface 001 is close to the user's eyes, and the temperature of the first surface 001 is relatively high. If the temperature detected by the temperature sensor is greater than or equal to a first value, the controller controls the switching sequence of the first lens 110 to the first timing sequence and controls the switching sequence of the second lens 120 to the second timing sequence. In the second wearing state, the first surface 001 is farther from the user's eyes, and the temperature of the first surface is relatively low. The controller controls the switching sequence of the first lens 110 to the second timing sequence and controls the switching sequence of the second lens 120 to the first timing sequence.
[0136] In this way, the wearing status of the shutter glasses can be obtained through the temperature sensor.
[0137] Similar to the aforementioned embodiment of the acquisition device 150 including a distance sensor, in some embodiments, a temperature sensor can be used to detect the second surface 002 (e.g., Figure 3 The temperature of the surface 003 (as shown) can be detected by a temperature sensor, or the temperature sensor can be used to detect the temperature of the third surface 003, or the temperature sensor can be used to detect the temperature of the fourth surface 004 (as shown). Figure 3 The temperature of the first lens 110 and the second lens 120 can be controlled by the controller based on the temperature of each of the aforementioned surfaces.
[0138] In some embodiments of this application, the acquisition device 150 includes a capacitance sensor. The capacitance sensor is used to detect the capacitance of the first surface 001. If the capacitance detected by the capacitance sensor is greater than or equal to a first value, the controller controls the switching timing of the first lens 110 to the first timing and controls the switching timing of the second lens 120 to the second timing. If the capacitance detected by the capacitance sensor is less than the first value, the controller controls the switching timing of the first lens 110 to the second timing and controls the switching timing of the second lens 120 to the first timing.
[0139] When a user approaches or touches the sensor, the capacitance of the first surface 001 changes. This change can be detected by the circuit and converted into an electrical signal, thereby detecting human contact. Thus, by detecting the capacitance of the first surface 001, the controller can control the switching timing of the first lens 110 and the second lens 120.
[0140] Similar to the aforementioned embodiment of the acquisition device 150 including a distance sensor, in some embodiments, a capacitive sensor can be used to detect the second surface 002 (e.g., Figure 3 The capacitance of the third surface 003 (as shown) can be detected by a temperature sensor, or the temperature sensor can be used to detect the capacitance of the fourth surface 004 (as shown). Figure 3 The capacitor (as shown). The controller can also control the switching timing of the first lens 110 and the second lens 120 based on the temperature of each of the aforementioned surfaces.
[0141] It is understood that, in the embodiments of this application, the acquisition device 150 is not limited to the foregoing example, and the acquisition device 150 may be other structures.
[0142] Additionally, in embodiments of this application, the shutter glasses 100 may include... Figure 5 The trigger 140 shown and Figure 6The acquisition device 150 is shown. This application embodiment does not limit the shutter glasses 100 to include only one of the trigger 140 and the acquisition device 150.
[0143] Figure 5 and Figure 6 In the example, shutter glasses 100 are clip-on glasses. Shutter glasses 100 may not include temples. Figure 6 In the example, the shutter glasses 100 may also include a clamp 201, to which both the first lens 110 and the second lens 120 are connected. The shutter glasses 100 can be connected to other wearable devices via the clamp 201.
[0144] For example, the shutter glasses 100 can be connected to eyeglasses such as nearsighted glasses, farsighted glasses, or sunglasses via the clamp 201. Alternatively, the shutter glasses 100 can be detachably connected to head-mounted devices such as helmets or headphones via the clamp 201.
[0145] For example, the clamp 201 is connected to the wearable device such that the first surface 001 of the first lens 110 faces the wearable device, and the shutter glasses are in a first wearing state. Alternatively, the clamp 201 is connected to the wearable device such that the second surface 002 of the first lens 110 faces the wearable device, and the shutter glasses are in a second wearing state.
[0146] In this way, the wearing status of the shutter glasses 100 can be changed relatively quickly through the clamp 201.
[0147] The structure of the clamping member 201 is not limited in the embodiments of this application. In some embodiments of this application, the clamping member 201 can be a snap fastener. The number of clamping members 201 can be one, two, three or more.
[0148] In some embodiments of this application, the shutter glasses 100 can be wearable glasses, which can be worn without the aid of other wearable devices.
[0149] Figure 7 This is an exploded view of the shutter glasses 100 provided in an embodiment of this application. Figure 7 and Figure 2 The differences include: the shutter glasses 100 may also include temples 202. The shutter glasses 100 and temples 202 are detachably connected, facilitating the switching of the shutter glasses 100 between a first wearing state and a second wearing state.
[0150] Figure 7In the example, the shutter glasses 100 may further include a first connector 211 and a second connector 222. Both the first lens 110 and the second lens 120 are connected to the first connector 211, and the second connector 222 is connected to the temple 202. The first connector 211 and the second connector 222 are detachably connected.
[0151] In the first wearing state, the first surface 001 of the shutter glasses 100 faces the free end of the temple 202. In the second wearing state, the first surface 001 of the shutter glasses 100 faces away from the free end of the temple 202. In other words, compared with the first wearing state, the first surface 001 is farther away from the free end of the temple 202 in the second wearing state.
[0152] The shutter glasses are in a first wearing state and a second wearing state, and both the first connector 211 and the second connector 222 can be connected.
[0153] In some embodiments, both the first connector 211 and the second connector 222 are magnetic structures. This allows for a detachable connection between the first connector 211 and the second connector 222. Furthermore, the magnetic structure can connect in multiple directions. For example, both opposite surfaces of the first connector 211 can be magnetically attracted to the second connector 222. Both the first connector 211 and the second connector 222 can be connected in both the first wearing state and the second wearing state.
[0154] In addition, the magnetic structure can have various shapes, which can be set according to the shape of the temple 202. This can minimize the volume of the first connector 211 and the second connector 222, reduce the space occupied by the shutter glasses 100, and also help reduce the weight of the shutter glasses 100.
[0155] In some embodiments of this application, the first connector 211 and the second connector 222 can be snapped together.
[0156] Figure 7 In the example, the first connector 211 includes a slot, and the second connector 222 includes a protrusion. The protrusion and the slot are inserted into each other.
[0157] Additionally, the first connector 211 and the second connector 222 have at least two insertion orientations. In a first state, the slot is inserted into the protrusion, with the first side of the protrusion facing the temple 202. In a second state, the slot is inserted into the protrusion, with the first side of the protrusion facing away from the temple 202. Exemplarily, in a first wearing state, the slot is inserted into the protrusion, with the first side of the protrusion facing the temple 202. In a second wearing state, the slot is inserted into the protrusion, with the first side of the protrusion facing away from the temple 202.
[0158] Thus, when the first connector 211 and the second connector 222 are connected, the first side of the first connector 211 can face the temple 202 or face away from the temple 202. Both the first connector 211 and the second connector 222 can be connected in both the first wearing state and the second wearing state, facilitating the user's switching between the first and second wearing states.
[0159] It is understood that in embodiments where the first connector 211 and the second connector 222 have at least two insertion orientations, the slots and protrusions have various shapes.
[0160] Figure 7 In this configuration, the slot is a square groove, and the protrusion is a square post. Thus, there are at least two insertion positions between the slot and the protrusion. In some embodiments, the slot is a square groove, and the protrusion is a square post. Thus, the slot and the protrusion have four insertion positions.
[0161] In some embodiments, the slot and the protrusion are interference-fitted.
[0162] Figure 8 This is a schematic diagram of the structure of another shutter glasses 100 provided in an embodiment of this application. Figure 8 and Figure 7 The differences include the different shapes of the protrusions and the slots.
[0163] Figure 8 In the example, the slot is a circular groove, and the protrusion is a circular cylinder. Thus, there are multiple insertion positions between the slot and the protrusion. When using the shutter glasses, the user can select the insertion position of the slot and the protrusion to better connect the temple 202 and the lens.
[0164] In some embodiments, the circular groove and the circular column are interference-fitted to increase the connection strength of the first connector 211 and the second connector 222, and to prevent the first connector 211 and the second connector 222 from separating and falling off during use.
[0165] Figure 8 For the remaining structures, please refer to the foregoing. Figure 7 The description in the text.
[0166] Figure 9 This is a schematic diagram of another shutter glasses 100 provided in an embodiment of this application. Figure 9 and Figure 7 The differences include the different shapes of the protrusions and the slots.
[0167] Figure 9 In the example, the slot is a curved groove structure, and the protrusion is a curved plate structure. Thus, there are two insertion positions between the slot and the protrusion. When using the shutter glasses, the user can select the insertion position of the slot and the protrusion for a better connection between the temple 202 and the lens.
[0168] In other embodiments of this application, the first connector 211 and the second connector 222 may be other structures, and are not limited to those described above. Figure 7 , Figure 8 and Figure 9 The example shown.
[0169] It is understood that in some embodiments of this application, the aforementioned slot may be disposed on the second connector 222, and the aforementioned protrusion may be disposed on the first connector 211. Similarly, the switching between the first wearing state and the second wearing state can be realized.
[0170] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
