Description

[Technical Field]

[0001] The present invention relates to a see-through display, and more particularly to a see-through display that can display an image from one side while allowing an effect on the user's vision from the other side. [Background technology]

[0002] Nowadays, virtual platforms are well developed and widely used to exchange information. If wearable devices can bridge the gap between virtual and real interactions, they can enhance the wearer's connection when using virtual platforms.

[0003] Eyeglasses are common accessories in daily life and are well suited to serve as an interaction medium for wearable devices. However, current methods for displaying images on eyeglasses (such as using semi-transparent coated lenses or perforated opaque lenses) can only display static images and cannot dynamically change the image. Furthermore, the displayed image may interfere with the wearer's vision. Therefore, one of the industry's goals is to develop eyeglasses that can display images without interfering with the wearer's vision. Summary of the Invention

[0020] Certain terms are used throughout this specification and claims to refer to particular components. As one skilled in the art will appreciate, hardware manufacturers may refer to components by different names. This specification does not intend to distinguish between components that differ in name but not function. In the following description and claims, the terms "include" and "comprise" are used in an open-ended manner and, therefore, should be interpreted to mean "including, but not limited to." Also, the term "couple" is intended to mean either an indirect or direct electrical connection. Thus, when a device is coupled to another device, the connection may be through a direct electrical connection or an indirect electrical connection via other devices and connections.

[0021] Please refer to FIG. 1. FIG. 1 is a schematic diagram illustrating a user interaction system 1 according to one embodiment of the present invention. As shown in FIG. 1, the user interaction system 1 includes a platform 10 and a see-through display 20. The platform 10 is coupled to the see-through display 20 and can provide display content for the see-through display 20 to display. Specifically, the display content can be various images or videos that can be dynamically displayed by the see-through display 20. Note that the see-through display 20 can be implemented in the form of, but is not limited to, a window, a door, a windshield, a showcase, a partition, a wall, a mask, eyewear, etc. For clarity, in the following embodiment, the see-through display is implemented as electrically controlled eyewear 30 as an example.

[0022] When the electrically controlled eyewear 30 displays the display content, the vision or line of sight of the wearer (i.e., the user of the electrically controlled eyewear 30) is not affected. In other words, the display content does not obstruct the user's vision. Note that not affecting the wearer's vision can also mean that the display content partially obstructs the wearer's vision, but the wearer can still clearly see his / her surroundings. Referring to FIG. 2, FIG. 2 is a schematic diagram showing the visual states of the front and back sides of the electrically controlled eyewear 30 according to an embodiment of the present invention. As shown in FIG. 2, an advertisement for a mobile phone is displayed on the front side of the electrically controlled eyewear 30, allowing passersby to see the advertisement. Meanwhile, ambient light can pass through the electrically controlled eyewear 30, allowing the wearer to clearly see their surroundings from the back side of the electrically controlled eyewear 30.

[0023] Please refer to FIG. 3. FIG. 3 is a schematic diagram illustrating the electrically controlled eyewear 30 shown in FIG. 1 according to an embodiment of the present invention. As shown in FIG. 3, the electrically controlled eyewear 30 includes a frame 202, a controller 204, and lenses 206. The controller 204 disposed in the frame 202 receives display content from the platform 10 and transmits control signals according to the display content. The lenses 206 are disposed in the frame 202 and coupled to the controller 204 to receive the control signals and display the display content accordingly. It should be noted that the electrically controlled eyewear 30 of the present invention does not necessarily include the frame 202; that is, the controller 204 and the lenses 206 may be configured or coupled in other forms. For example, the controller 204 may be a plug-in or magnetic eyeglass accessory. The lenses 206 may also be combined with other wearable devices, such as, but not limited to, virtual reality devices, augmented devices, sunglasses, vision correction glasses, snow goggles, helmets, or masks.

[0024] To prevent display content displayed on the lens 206 from interfering with ambient light passing through the lens 206, the present invention utilizes various components to control the polarization state of light. See FIG. 4, which is a schematic diagram illustrating a see-through display using the lens 206 according to an embodiment of the present invention. The lens 206 includes a polarization converter 2061 disposed between a polarizing component 2062 and a partially reflective mirror component 2063. The polarizing component 2062 confines the polarization state of the ambient light, the partially reflective mirror component 2063 reflects and transmits the ambient light, and the polarization converter 2061 converts the polarization state of the ambient light passing through the polarizing component 2062. Note that at least one of the polarizing component 2062, the partially reflective mirror component 2063, and the polarization converter 2061 is a liquid crystal panel with an active matrix connected to the controller 204 to display the display content according to a control signal. In one embodiment, as shown in FIG. 4 , when polarization converter 2061 displays display content in accordance with the control signal and ambient light L1 strikes polarization component 2062 of lens 206, ambient light L1 passes through three components to become transmitted light L2, L3, and L4, respectively. Furthermore, a portion of transmitted light L3 is reflected by partially reflective mirror component 2063 and transmitted through polarization converter 2061 and polarization component 2062, as shown by reflected light L5 and transmitted light L6 and L7 in FIG. 4 . In this way, the wearer can see transmitted light L4, as shown in FIG. 2 . That is, the wearer can see their surroundings (e.g., roads and scenery) from the back side of electrically controlled eyewear 30.

[0025] Furthermore, the controller 204 can use the control signal to apply a voltage to the polarization converter 2061 to change the liquid crystal in the polarization converter 2061 to a first orientation. Specifically, ambient light L1 is polarized into transmitted light L2, which has a linear polarization state (indicated by the double arrow on the transmitted light L2 in FIG. 4). When a voltage is applied to the polarization converter 2061, the first orientation of the liquid crystal does not change the polarization state of the transmitted light L2, as shown on the right side of FIG. 4. Specifically, transmitted light L3 has a linear polarization state, and reflected light L5, transmitted light L6, and transmitted light L7 also have linear polarization states. This allows passersby to see the transmitted light L7 in a linear state. That is, the display area of the polarization converter 2061 has a high reflectivity on the front side. Note that local light modulation of the liquid crystal in the liquid crystal converter 2061 changes the reflectivity on the front side, thereby displaying the display content. While displaying content, the transmittance of the lens hardly changes.

[0026] Conversely, the controller 204 can instruct the polarization converter 2061 to have no voltage applied via a control signal (as shown on the left side of FIG. 4 ), causing the liquid crystals in the polarization converter 2061 to change to a second orientation. Specifically, ambient light L1 is polarized to become transmitted light L2 in a linear state. When no voltage is applied to the polarization converter 2061, as shown on the left side of FIG. 4 , the second orientation of the liquid crystals can change the polarization state of the transmitted light L2. That is, transmitted light L3 has either a left-handed or right-handed polarization state, and accordingly, reflected light L5 has either a right-handed or left-handed polarization state. When reflected light L5 in a right-handed or left-handed polarization state passes through the polarization converter 2061 with no voltage applied, transmitted light L6 has a linear polarization state that is orthogonal to that of the transmitted light L2. When linearly polarized light L6 enters the polarization component 2062, the linearly polarized light L6 cannot pass through the polarization component 2062, and the display area of the polarization converter 2061 exhibits low reflectivity toward the front side. It should be noted that the change in polarization state caused by differently polarized light entering different components is well known in the art and will not be repeated here. Furthermore, the above polarization state control method is merely one embodiment. Other embodiments of the present invention can utilize other polarization state modulation methods, and those skilled in the art can make appropriate adjustments according to system requirements. For example, the polarization component 2062 can generate left-handed or right-handed polarized light, resulting in darker transmitted light L6 when the liquid crystal of the polarization converter 2061 is vertical and brighter transmitted light L6 when the liquid crystal of the polarization converter 2061 is horizontal.

[0027] It should be noted that FIG. 4 merely illustrates one embodiment of the present invention, and those skilled in the art can make appropriate adjustments according to system requirements. For example, the see-through display can further include a tinting component adjacent to the partially reflective mirror component 2063 or integrated with the partially reflective mirror component 210. The tinting component can adjust the transmittance and reflectance of the lens 206, and the electrically controlled eyewear 30 can function as sunglasses for the wearer. For example, the see-through display can further include a diffuser to widen the viewing angle of the display content displayed on the electrically controlled eyewear 30. The diffuser can be a surface with a microstructure, such as bumps, slopes, or squares. The surface can be integrated with the partially reflective mirror. The diffuser can be a film with a micropatterned refractive index distribution.

[0028] Meanwhile, the polarization converter 2061, the polarization component 2062, and the partially reflective mirror component 2063 may have various implementation forms as long as the basic functions of each component can be realized, and this is within the scope of the present invention. For example, the polarization component 2062 may be a polarizer, a color filter, a wave plate, an anti-reflection film, an anti-fouling film, an angle attenuation filter, or a combination of the above components. The above components are not limited to the polarization component 2062 and can be added at any position within the lens. The characteristics of the above components can be configured to be controlled graphically or electronically according to the shape and position of the pixel. The polarization component 2062 may be made of a material including iodine or a dye-based material. The polarization converter 2061 may be an active matrix liquid crystal panel or a passive matrix liquid crystal panel. The aperture ratio of the polarization converter 2061 may be greater than 50%, and the liquid crystal display panel may be integrated with a touch sensor. Additionally, polarization converter 2061 can be implemented with zenithal bistable alignment or cholesteric liquid crystal to operate in a bistable state for power conservation. Note that each pixel of polarization converter 2061 can have a curved, sawtooth, or polygonal shape, the opaque line of polarization converter 2061 can be thinner than 15 microns, and the size of each pixel of polarization converter 2061 can be larger than 100 microns by 100 microns. For example, FIG. 5A is a schematic diagram illustrating various shapes of each pixel of polarization converter 2061 according to embodiments of the present invention. In this manner, the diffraction or screen door effect of polarization converter 2061 can be reduced. The liquid crystal panel can be configured to operate in twisted nematic, electrically controlled birefringence, optically compensated bending, in-plane switching, fringe field switching, vertical alignment, ferroelectric liquid crystal, cholesteric liquid crystal, dye-doped liquid crystal, or polymer-dispersed liquid crystal modes. Additionally, the partially reflective mirror component 2063 may be metallic or dielectric coated.It should also be noted that the principles behind polarization converter 2061, polarizing component 2062, and partially reflecting mirror component 2063 should be well known in the art and will not be repeated here.

[0029] Furthermore, the polarizing component 2062 and the partially reflective mirror component 2063 can be implemented using various types of liquid crystals. In one embodiment, the partially reflective mirror component 2063 can include microstructures or a micro-refractive index distribution to diffuse ambient light. In another embodiment, a diffuser is attached directly to the partially reflective mirror component. In one embodiment, the polarizing component 2062 is a first liquid crystal panel with a dichroic dye, and the partially reflective mirror component 2063 within the lens 40 is a second liquid crystal panel filled with a cholesteric liquid crystal layer. Specifically, the extinction ratio of the first liquid crystal layer with the dichroic dye can be electrically adjusted to control the visibility and visual brightness of the displayed content. By locally controlling the extinction ratio, the polarizing component 2062 can also provide a display function. In another embodiment, the partially reflective mirror component 2063 is a first liquid crystal panel filled with a cholesteric liquid crystal layer, and the reflection of the cholesteric liquid crystal can be electrically adjusted to control the visibility and visual brightness of the displayed content. By locally controlling the reflectivity, the partially reflective mirror component 2063 may also provide a display function. On the other hand, the liquid crystals in the cholesteric liquid crystal layer may be aligned in a geometric distribution to provide additional phase modulation to the wearer's vision. In one embodiment, when the polarization converter 2061, the polarizing component 2062, and the partially reflective mirror component 2063 are realized with respective types of liquid crystals, any of the polarization converter 2061, the polarizing component 2062, and the partially reflective mirror component 2063 may divide the lens 20 into a display area for display content and a non-display area. For example, FIG. 5B is a diagram schematically illustrating various patterns of display areas and non-display areas according to embodiments of the present invention.

[0030] 6A-6D are schematic diagrams illustrating the dispersion characteristics of three components of a see-through display 20 according to an embodiment of the present invention. As shown in FIGS. 6A-6D, by separately adjusting the dispersion characteristics of the three components of the see-through display 20 with respect to wavelength, the present invention can realize a see-through display capable of displaying colors. Specifically, FIG. 6A illustrates the reflectance and transmittance of the partially reflective mirror component 2063 with respect to the wavelength spectrum, FIG. 6B illustrates various reflectances of the lens 206 under different operating voltages, FIG. 6C illustrates the reflectance of the lens 206 with respect to the wavelength spectrum, and FIG. 6D illustrates the transmittance spectrum of the lens 206 under different operating voltages. Adjusting dispersion characteristics according to wavelength is well known in the art and will not be repeated here.

[0031] In another embodiment, each display gray level of the see-through display 20 corresponds to a specific color (as shown in FIG. 6C ). When the see-through display 20 compiles and displays the display gray levels, the color digital display content (RGB) to be displayed needs to be converted into digital drive signals compatible with the see-through display 20. This conversion requires a gamma table that describes the color and light intensity corresponding to each display gray level. It should be noted that the conversion of the drive digital signals can be performed by system firmware, system software, drive hardware, or a combination of the above.

[0032] In other embodiments, the liquid crystal panel may include multiple pixels. Each pixel includes multiple subpixels, and the display color of each pixel is mixed with the colors of the subpixels operating at various display gray levels. In a typical RGB color mode, each subpixel controls one of the red, green, and blue gray levels. The drive signals for the RGB subpixels directly correspond to a typical RGB data format. On the other hand, in the see-through display 20, a specific RGB color to be displayed is mixed with multiple subpixels operating at different display gray levels. All subpixels share the same gamma table, and each gray level corresponds to a set of light intensity and RGB colors. As shown in FIG. 7, the original color to be displayed is a mixture of RGB operating at various display gray levels and the corresponding RGB color. In other words, the original color needs to be converted into three or more identical pixels operated by mixing multiple different RGB combinations. Under these characteristics, the formation of the subpixels of the see-through display 20 can be distributed spatially or temporally. The number and configuration of the subpixels that mix the pixel can be adjusted through signals from the controller 204. Furthermore, the resolution can also be increased by wobulation techniques.

[0033] In another embodiment, as shown in FIG. 6D , the transmittance and spectrum of the see-through display 20 remain unchanged when it operates at various display gray levels. However, the transmittance and reflectance of obliquely incident light at different interfaces change depending on the polarization state of the incident light. Therefore, content displayed on the front reflective surface is transparently viewable at large viewing angles. To reduce the degree of leakage of the displayed content at large angles, compensation components may be added to the see-through display 20, such as, but not limited to, adding a retardation film or coating to reduce the Fresnel reflection polarization difference at the interface, or using a segmented retardation film with locally oriented LCs. In this way, light in the viewing angle direction maintains the same polarization state.

[0034] In another embodiment, the lens may further include an optical compensation component that reduces the difference in transmittance of light passing through the lens at an angle when switching between different display gray levels. The optical compensation component may be a film, a coating, or a liquid crystal panel.

[0035] In another embodiment, the see-through display 20 or the electrically controlled eyewear 30 may further include a light source 2064 to provide sufficient light. See FIGS. 8A-8E. FIGS. 8A-8E are schematic diagrams illustrating electrically controlled eyewear 30 according to an embodiment of the present invention. Specifically, for various positions of the light source 2064, the lens of the present invention may be further configured with an additional polarizing component or waveguide. For example, as shown in FIGS. 8A-8B, the light source 2064 is positioned above the polarizing component 2062 to provide sufficient light to the electrically controlled eyewear 30. Note that the lens 206 in FIG. 8B further includes a waveguide 2065 to guide light to the polarizing component 2062. As shown in FIGS. 8C-8E, the light source 2064 is positioned to the side of the lens 206 to provide sufficient light to the electrically controlled eyewear 30. Note that the lens 206 in FIGS. 8C-8E further includes a waveguide 2065 and an additional polarizing component 2066 to guide light to various positions on the lens. 8A-8B illustrate only one embodiment of the present invention, and those skilled in the art can make appropriate adjustments according to system requirements. In another embodiment, the see-through display 20 may further include another transparent display having an active light source.

[0036] 9, displaying display content on the see-through display 20 or the electrically controlled eyewear 30 can be summarized as flow 50. Flow 50 includes the following steps:

[0037] Step S500: Digital content is created by a designer.

[0038] Step S502: The digital content is provided from the platform 10 to the see-through display 20 or the electronically controlled eyewear 30.

[0039] Step S504: The digital content is displayed on the see-through display 20 or the electrically controlled eyewear 30.

[0040] In step S500, a designer, such as a company, store, or individual, creates display content to provide to the platform 10. The display content may be in the form of an image, a graph, or a video. The display content may be a product advertisement, an emoticon, a digital work of art such as an NFT, or a game product.

[0041] In step S502, the platform 10 provides display content to the end user's electronically controlled eyewear 30. The platform 10 may include hardware that executes software for providing display content to the electronically controlled eyewear 30. For example, the hardware may be a mobile phone, a computer, a system-on-chip, an in-vehicle system, or a broadcast system. The software may be social media, an application program, or a game program.

[0042] In step S504, the controller 204 receives the display content and controls the lens 206 to display the display content. In this way, passersby can see the display content displayed on the front of the electrically controlled eyewear 30.

[0043] Further, please refer to Fig. 10. Fig. 10 is a diagram schematically illustrating a user interaction system 9 according to an embodiment of the present invention. As shown in Fig. 9, the user interaction system 9 can function as an interaction platform for multiple users and electrically controlled eyewear worn by the multiple users. Note that the detailed description of the lenses of the electrically controlled eyewear and the consequential modifications have been described above and will not be repeated here.

[0044] In summary, the electrically controlled eyewear of the present invention utilizes a lens including a liquid crystal panel disposed between a polarizing component and a partially reflective mirror component to further control the transmitted and reflected light after ambient light strikes the lens, thereby allowing passersby to view the display content displayed on the front of the electrically controlled eyewear without affecting the user's vision.
