Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.
[0036] At least one embodiment of this disclosure provides a dimming method for dimming a lens of a near-eye display device. The lens includes a lens body and a display screen stacked together. The method includes: acquiring a dimming control signal; controlling the display screen to display a dimming pattern based on the dimming control signal; wherein the dimming pattern includes a light-transmitting area and a light-blocking area, the light-blocking area is located on at least one side of the light-transmitting area, and the light transmittance of the light-transmitting area is greater than the light transmittance of the light-blocking area; the lens body includes a viewing area for a user to gaze at, and in the stacking direction of the lens body and the display screen, the light-blocking area overlaps with at least a portion of the lens body other than the viewing area to block ambient light incident on the user's eyes.
[0037] At least one embodiment of this disclosure provides a near-eye display device, comprising: a lens, including a lens body and a display screen stacked together; a controller electrically connected to the display screen; the controller being configured to acquire a dimming control signal and control the display screen to display a dimming pattern based on the dimming control signal; wherein the dimming pattern includes a light-transmitting area and a light-blocking area, the light-blocking area being located on at least one side of the light-transmitting area, and the light transmittance of the light-transmitting area being greater than the light transmittance of the light-blocking area; the lens body including a viewing area for a user to gaze at, and in the stacking direction of the lens body and the display screen, the light-blocking area overlaps with at least a portion of the lens body other than the viewing area to block ambient light incident on the user's eyes.
[0038] At least one embodiment of this disclosure provides a dimming device configured to dim a lens of a near-eye display device. The lens includes a lens body and a display screen stacked together. The dimming device includes: an acquisition module configured to acquire a dimming control signal; and a dimming module configured to control the display screen to display a dimming pattern based on the dimming control signal. The dimming pattern includes a light-transmitting area and a light-blocking area, the light-blocking area being located on at least one side of the light-transmitting area, and the light transmittance of the light-transmitting area being greater than that of the light-blocking area. The lens body includes a viewing area for a user to gaze at. In the stacking direction of the lens body and the display screen, the light-blocking area overlaps with at least a portion of the lens body other than the viewing area to block ambient light incident on the user's eyes.
[0039] At least one embodiment of this disclosure provides an electronic device, including: a memory that non-transitoryly stores computer-executable instructions; and a processor configured to execute the computer-executable instructions, wherein the computer-executable instructions are executed by the processor to implement the dimming method described above.
[0040] At least one embodiment of this disclosure provides a non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer-executable instructions that, when executed by a processor, implement the dimming method described above.
[0041] The dimming method, near-eye display device, dimming device, electronic device, and storage medium provided in at least one embodiment of this disclosure utilize a light-blocking area with low light transmittance to block ambient light in at least a portion of the area outside the viewing area. This allows for dynamic control of the intensity of light entering the user's eye from different areas of the lens, creating a contrast between the viewing and non-viewing areas. Consequently, interference from ambient light in the non-viewing area on the ambient light in the user's viewing area is reduced, optimizing the display effect of the near-eye display device and enhancing the user's visual comfort.
[0042] The dimming method, near-eye display device, dimming device, electronic device, and storage medium are described below with reference to the accompanying drawings and through some embodiments.
[0043] Figure 1 This is a schematic flowchart illustrating a dimming method provided in at least one embodiment of the present disclosure. Figure 2 This is a schematic diagram of a near-eye display device provided as an example in at least one embodiment of the present disclosure. Figure 3 for Figure 2 A schematic diagram of the lens in the near-eye display device shown.
[0044] refer to Figure 1 , Figure 2 and Figure 3This disclosure provides a dimming method for dimming a lens 100 of a near-eye display device. The lens 100 includes a lens body 110 and a display screen 120 stacked together. For example, see reference... Figure 3 In the stacked lens body 110 and display screen 120, the lens body 110 can be located between the display screen 120 and the user's eye 200, that is, the lens body 110 can be closer to the user's eye 200 than the display screen 120. However, this disclosure is not limited to this; for example, the display screen can also be located between the lens body and the user's eye.
[0045] refer to Figure 1 , Figure 2 and Figure 3 The method includes the following steps S1 to S2. S1: Obtain a dimming control signal. S2: Control the display screen 120 to display the dimming pattern P based on the dimming control signal.
[0046] refer to Figure 3 The dimming pattern P includes a light-transmitting area P1 and a light-blocking area P2, wherein the light-blocking area P2 is located on at least one side of the light-transmitting area P1, and the light transmittance of the light-transmitting area P1 is greater than that of the light-blocking area P2. For example, the light-blocking area may be located only on one side of the light-transmitting area. For example, the light-blocking area may be located on opposite sides of the light-transmitting area. For example, the light-blocking area may be located around the light-transmitting area, such as surrounding the light-transmitting area.
[0047] For example, the higher the light transmittance, such as the closer it is to 100%, the greater the amount of light transmitted through the medium. For instance, if the minimum light transmittance of the light-transmitting area is greater than the maximum light transmittance of the light-blocking area, then the amount of light transmitted to the light-transmitting area is greater than the amount of light transmitted to the light-blocking area.
[0048] For example, the light transmittance of the light-transmitting area can be uniform or non-uniform. Similarly, the light transmittance of the shading area can be uniform or non-uniform. When the light transmittance of the light-transmitting area is uniform, the light transmittance of different areas within that area is the same. When the light transmittance of the shading area is uniform, the light transmittance of different areas within that area is the same. When the light transmittance of the light-transmitting area is non-uniform, at least two areas within that area have different light transmittance, and the minimum light transmittance of the light-transmitting area is greater than the light transmittance of the shading area. Similarly, when the light transmittance of the shading area is non-uniform, at least two areas within that area have different light transmittance, and the maximum light transmittance of the shading area is less than the light transmittance of the light-transmitting area. It can be understood that when both the light transmittance and shading area are non-uniform, the minimum light transmittance of the light-transmitting area is greater than the maximum light transmittance of the shading area.
[0049] refer to Figure 3The lens body 110 includes a viewing area Z1 for the user to gaze at. In the stacking direction M of the lens body 110 and the display screen 120, a light-blocking area P2 overlaps with at least a portion of the lens body 110 other than the viewing area Z1, to block ambient light incident on the user's eye 200. For example, the viewing area Z1 refers to the area that the user 200 is gazing at. For example, ambient light refers to real-world light. For example, the area other than the viewing area Z1 can be a non-viewing area Z2.
[0050] For example, the shading of ambient light by a shading area refers to reducing the transmittance of ambient light. For example, a shading area may block some light while allowing some light to pass through, or it may block all light; this disclosure does not impose any limitations on this.
[0051] For example, in the stacking direction, the shading area and the non-focusing area may partially overlap and partially not overlap. For example, in the stacking direction, the shading area and the non-focusing area may completely overlap. For example, in the stacking direction, the shading area may be located within the non-focusing area. For example, in the stacking direction, the non-focusing area may be located within the shading area.
[0052] For example, a shaded area can block ambient light from penetrating a portion of the non-focused area. Alternatively, a shaded area can block ambient light from the entire non-focused area. For example, through the shaded area, the user perceives the focused area as bright and the non-focused area as dark.
[0053] For example, refer to Figure 3 When the lens body 110 is located between the display screen 120 and the user's eye 200, the light-blocking area P2 can block ambient light to reduce the light incident on the non-focusing area Z2 of the lens body 110. For example, when the display screen is located between the lens body and the user's eye, ambient light in the non-focusing area transmitted to the lens body can be blocked by the light-blocking area of the dimming pattern displayed on the display screen, thereby reducing the light incident on the user's eye after passing through the non-focusing area.
[0054] The dimming method provided in this disclosure utilizes a light-blocking area with low light transmittance to block ambient light in at least a portion of the area outside the viewing area. This allows for dynamic control of the intensity of light entering the user's eye from different areas of the lens, creating a contrast between the viewing and non-viewing areas. Consequently, it reduces interference from ambient light in the non-viewing area on the ambient light in the user's viewing area, optimizes the display effect of the near-eye display device, and enhances the user's visual comfort.
[0055] For example, when both the light-transmitting and shading areas have uniform light transmittance, the ratio of light transmittance in the light-transmitting area to that in the shading area can be equal to 2. Alternatively, the ratio can be greater than 2. For instance, the light transmittance in the light-transmitting area can be 50%, and the light transmittance in the shading area can be 25%, achieving a 2:1 contrast ratio for better light and dark contrast.
[0056] For example, when the light transmittance of the light-transmitting area and the light-blocking area are not uniform, a ratio between the minimum light transmittance of the light-transmitting area and the maximum light transmittance of the light-blocking area can be set.
[0057] However, this disclosure is not limited to this, and the ratio of light transmittance of the light-transmitting area to that of the light-blocking area can be set according to actual needs.
[0058] refer to Figure 3 For example, in the stacking direction M of the lens body 110 and the display screen 120, the viewing area Z1 and the light-transmitting area P1 overlap. For example, in the stacking direction, the viewing area may completely coincide with the light-transmitting area. For example, in the stacking direction, the viewing area and the light-transmitting area may partially overlap, and partially not overlap. For example, in the stacking direction, the viewing area may be located within the light-transmitting area. For example, in the stacking direction, the light-transmitting area may be located within the viewing area. It is understood that the overlap relationship between the viewing area and the light-transmitting area can be set according to actual needs, and this disclosure does not impose any limitations on this.
[0059] For example, after determining the gaze area of the lens body, the edge of the light-transmitting area can be determined based on the edge of the gaze area. For example, referring to the example described later, the gaze area can be determined based on gaze information, thereby determining the object the user is focusing on and determining the light-transmitting area.
[0060] For example, after determining the light-transmitting area of the display screen, the user can be guided to look towards that area to form a gaze zone. By making the gaze zone stand out relative to the non-gaze zone, a "highlight" visual effect can be created, which helps guide the user's gaze.
[0061] For example, users can pre-set the area of the light-transmitting zone and the relative positional relationship between the light-transmitting zone and the light-blocking zone in different modes. For example, the area of the light-transmitting zone and the relative positional relationship between the light-transmitting zone and the light-blocking zone can be determined based on the size of the object being viewed. It is understood that the area of the light-transmitting zone can be set according to actual needs, and this disclosure does not impose any restrictions on it.
[0062] refer to Figure 3 and Figure 4In some examples, the display screen 120 is a liquid crystal display screen, which includes a plurality of sub-pixels 124, and the dimming control signal includes voltage signals of at least some of the sub-pixels 124. By controlling the voltage signals of the sub-pixels 124, the transmittance of the sub-pixels 124 can be adjusted, thereby forming a dimming pattern from the plurality of sub-pixels 124.
[0063] For example, an LCD screen can be a monochrome LCD screen. A monochrome LCD screen, also known as a black-and-white LCD screen, typically displays black text on a white background or white text on a black background.
[0064] It should be noted that in the embodiments of this disclosure, the division of different regions can be determined based on the edge of the light-emitting area of the sub-pixel. For example, in the aforementioned example, the light transmittance of the sub-pixel in the light-transmitting area is greater than the light transmittance of the sub-pixel in the light-blocking area. For example, in the following examples, the division of the first and second regions within the light-blocking area can be determined by setting the light transmittance of the sub-pixels in different regions to define the boundary between the first and second regions. This disclosure will not be elaborated further in the following description.
[0065] Figure 4 This is a schematic diagram of a display screen provided as an example in at least one embodiment of the present disclosure.
[0066] In near-eye display devices, the display screen can use a liquid crystal layer to precisely control the amount of ambient light transmitted, thereby achieving an augmented reality effect. Figure 4 The schematic diagram illustrates the stacked structure of the display screen. (Reference) Figure 4 The display screen 120 includes a first substrate 121, a second substrate 122, and a liquid crystal layer 123. The first substrate 121 and the second substrate 122 are disposed opposite to each other, and the liquid crystal layer 123 is disposed between the first substrate 121 and the second substrate 122. The display screen 120 also includes a first polarizer 125 and a second polarizer 126. The first polarizer 125 is located between the first substrate 121 and the liquid crystal layer 123, and the second polarizer 126 is located between the second substrate 122 and the liquid crystal layer 123. For example, a sub-pixel 124 includes a thin film transistor (TFT) T1, which is located between the liquid crystal layer 123 and the first polarizer 125.
[0067] refer to Figure 4Thin-film transistors (TFTs) can control the deflection direction of liquid crystal molecules in the liquid crystal layer under different states, thereby adjusting the brightness and darkness of the corresponding area. For example, when the TFT T1 of sub-pixel 1241 is turned on, the light transmittance of the area in the liquid crystal layer 123 corresponding to sub-pixel 1241 is high, and the light intensity of light L1 is high, resulting in a bright state. When the TFT T2 of sub-pixel 1242 is turned off, the light transmittance of the area in the liquid crystal layer 123 corresponding to sub-pixel 1242 is low, and the light intensity of transmitted light L2 is reduced, resulting in a dark state.
[0068] For example, Figure 4 The illustration schematically shows liquid crystal molecules in a bright state when vertically aligned and in a dark state when tilted. For example, a parallel polarizer can be placed on the side of the liquid crystal layer away from the sub-pixel to achieve the bright-dark state transition by utilizing the interaction of the parallel polarization state with the liquid crystal layer. However, this disclosure is not limited to this; for example, an orthogonal polarizer can be placed on the side of the liquid crystal layer away from the sub-pixel, where the orthogonal polarizer interacts with the liquid crystal layer. In this case, the liquid crystal molecules are in a dark state when vertically aligned and in a bright state when tilted.
[0069] For example, Figure 4 The illustration schematically shows that when the thin-film transistor (TFT) is turned on, the area in the liquid crystal layer corresponding to the sub-pixel is in a bright state, and when the TFT is turned off, the area in the liquid crystal layer corresponding to the sub-pixel is in a dark state. However, this disclosure is not limited to this. For example, it can be configured as needed: when the TFT of the sub-pixel is turned off, the area in the liquid crystal layer corresponding to the sub-pixel is in a dark state, and when the TFT of the sub-pixel is turned on, the area in the liquid crystal layer corresponding to the sub-pixel is in a bright state.
[0070] Understandable, Figure 4 This illustration merely demonstrates how a display screen can adjust the brightness and darkness of localized areas using thin-film transistors. However, this disclosure does not limit the structure of the display screen.
[0071] Specifically, the liquid crystal layer can be a thin layer of liquid crystal material, which can be either a twisted nematic (TN) type liquid crystal material or an in-plane switching (IPS) type liquid crystal material. The liquid crystal molecules in the liquid crystal layer can change their arrangement according to changes in the electric field.
[0072] The polarization direction of the polarizer (such as the first and second polarizers in the example above) determines how light interacts with the arranged liquid crystal molecules.
[0073] A thin-film transistor can be viewed as a miniature switch, with each sub-pixel or each dimming area corresponding to an independent thin-film transistor, thereby using the thin-film transistor to control the electric field applied to the liquid crystal layer.
[0074] During the dimming process of a display screen, a voltage is applied to the gate of a thin-film transistor (TFT), which turns on and activates the TFT, allowing current to flow and charging the capacitor associated with the corresponding sub-pixel. The charged capacitor generates an electric field, causing the liquid crystal molecules in the liquid crystal layer to align in a specific pattern. This alignment of the liquid crystal molecules, in conjunction with a polarizer, controls the light passing through the sub-pixel. For example, the electric field can allow light to pass through (bright state) or block light (dark state). Since each sub-pixel corresponds to an independent TFT, the amount of light transmitted through each sub-pixel can be controlled individually, making complex dimming modes possible.
[0075] It is understood that the display screen provided in this disclosure embodiment is a non-light-emitting device to reduce power consumption. That is, the display screen in this disclosure embodiment uses the deflection direction of liquid crystal molecules in the liquid crystal layer and the polarizer to change the light transmittance, but does not actively emit light. In other embodiments, near-eye display devices such as AR glasses include micro light-emitting diode (Ultra-LED, uLED) optical engines, and the display power consumption of a single-eye uLED optical engine is approximately 300 milliwatts to 500 milliwatts. The power consumption of a single-eye display screen provided in this disclosure embodiment can be as low as 10 milliwatts.
[0076] In AR glasses that include the aforementioned uLED optical engine and waveguide, the weight of each eye exceeds 30 grams. Furthermore, to match the power consumption of the uLED optical engine, a larger battery capacity is required, further increasing the weight of the AR glasses. The near-eye display device provided in this disclosure eliminates the need for a uLED optical engine and waveguide, and requires a smaller battery capacity, thus achieving a weight reduction of 35 to 40 grams compared to AR glasses in other embodiments. Therefore, the near-eye display device provided in this disclosure is easily made lightweight, facilitating all-day wear.
[0077] Furthermore, the high cost of uLED optical engines and waveguides contributes to the high cost of AR glasses in other embodiments. The near-eye display device provided in this disclosure significantly reduces costs by using a liquid crystal display screen.
[0078] refer to Figure 1 and Figure 3 Step S1 includes determining the gaze area Z1 based on the user's gaze information, and acquiring a dimming control signal based on the gaze area Z1. The dimming control signal includes the mapping relationship between the gaze area Z1 and the light-transmitting area P1. By acquiring the user's gaze information, the area that the user wants to view can be determined as the gaze area. Therefore, the dimming pattern displayed on the screen can be dynamically controlled according to the user's viewing needs, improving the user's visual comfort.
[0079] For example, the above mapping relationship may include the relative positional relationship between the edge of the gaze area and the edge of the light-transmitting area. For example, the above mapping relationship may include the relationship between the coordinate information of the edge of the gaze area and the coordinate information of the edge of the light-transmitting area. For example, the above coordinate information may be the coordinate information of a sub-pixel. For example, the above mapping relationship may also include relationships such as the area of the gaze area and the area of the light-transmitting area; this disclosure does not limit this.
[0080] refer to Figure 3 The gaze information includes the user's gaze direction. For example, the gaze direction refers to the direction V in which the user's pupils 200 point towards the object being gazed at 300. For example, the gaze direction can change dynamically with the movement of the user or the object being gazed at. For example, the object being gazed at 300 can be an object in the real world that the user is paying attention to.
[0081] For example, in conjunction with the examples described later, an eye-tracking module can be used to obtain the user's gaze information.
[0082] For example, after obtaining the user's gaze direction, methods such as triangulation can be used to determine the edge of the gaze area.
[0083] For example, refer to Figure 3 When a user is looking at the object 300, the light-transmitting area P1 in the dimming pattern P can be set at the position corresponding to the viewing area Z1, and the light-blocking area P2 can be used to block the light from the non-viewing area Z2. For example, the viewing area Z1 is the area where the user can see the object 300 in the viewing direction V.
[0084] Figures 5 to 8 A schematic diagram of a display screen showing different dimming patterns in a near-eye display device provided in at least one embodiment of this disclosure.
[0085] refer to Figure 5 In the shading area P2, different regions have the same light transmittance. For example, any two sub-pixels in the shading area P2 have the same light transmittance. Therefore, the boundary between the shading area P2 and the light-transmitting area P1 is clearer, and a more obvious contrast can be formed between them. Consequently, the shading area P2 can better reduce the interference of ambient light from the non-focused area on the ambient light of the user's focused area, resulting in greater viewing comfort when the user looks at the object within the light-transmitting area P1.
[0086] refer to Figure 6The light-blocking area P2 includes a first area P21 and a second area P22. The first area P21 surrounds the light-transmitting area P1, and the second area P22 is located on at least one side of the first area P21. The light transmittance of the first area P21 is less than that of the second area P22. For example, the second area can be located on one side of the first area. For example, the second area can be located on both sides of the first area. For example, the second area can be located around the periphery of the first area, that is, the second area can surround the first area.
[0087] refer to Figure 6 Since the first zone P21 surrounds the light-transmitting zone P1, setting the light transmittance of the first zone P21 in the shading zone P2 to be smaller can increase the contrast between the first zone P21 and the light-transmitting zone P1, making the object being viewed in the light-transmitting zone P1 stand out more. Furthermore, setting the light transmittance of the second zone P22 to be larger allows the user to view other objects through the second zone P22, such as the user's surrounding environment in the real world.
[0088] refer to Figure 6 , Figure 6 The diagram schematically illustrates that the first area P21 and the second area P22 in the light-shielding area P2 have a transmittance that linearly varies in direction X. In some examples, the transmittance of the light-shielding area P2 is gradually varied. Along direction X, parallel to the display surface 1200 of the display screen 120, the transmittance of the light-shielding area P2 gradually increases from the side of the first area P21 away from the second area P22 towards the side of the first area P21 closer to the second area P22. For example, direction X can be the arrangement direction of the first area P21 and the second area P22. Setting the transmittance of the first area P21 to the second area P22 to gradually increase facilitates a natural transition between the first area P21 and the second area P22. This reduces eye discomfort when facing areas with large differences in brightness, improving user comfort.
[0089] However, this disclosure is not limited thereto. For example, the first region may have a regionally varying transmittance. For example, the second region may have a regionally varying transmittance. For example, the transmittance of the first region may be uniform. For example, the transmittance of the second region may be uniform.
[0090] For example, the regional gradient referred to in the embodiments of this disclosure means that a certain region (e.g., the first region or the second region) may include a plurality of sub-regions arranged in sequence, each sub-region having uniform light transmittance, and the light transmittance of the plurality of sub-regions gradually changing in the arrangement direction of the plurality of sub-regions.
[0091] For example, the arrangement direction of multiple sub-regions can be the same as the arrangement direction of the first and second regions.
[0092] It should be noted that the embodiments disclosed herein use a planar display surface as an example. However, this disclosure is not limited to this. For example, when the display surface is curved, a plane parallel to the tangent of the curved surface can be used as a reference plane, that is, the direction parallel to the display surface can be a direction parallel to the reference plane.
[0093] For example, the display surface of the screen can be used to display a dimming pattern. However, this disclosure is not limited to this; for example, the display surface of the screen can also display other content, such as virtual information in the examples described later.
[0094] refer to Figure 7 and Figure 8 The light transmittance of the light-blocking area P2 gradually decreases from the edge of the light-transmitting area P1 closer to the edge of the light-transmitting area P1 further away from the light-transmitting area P1. This allows for a natural transition between the light-blocking area P2 and the light-transmitting area P1, reducing discomfort for the user's eyes when facing areas with large differences in brightness and improving user comfort.
[0095] For example, Figure 7 The diagram schematically illustrates that the light-blocking area P2 is located to one side of the light-transmitting area P1, and the light transmittance of the light-transmitting area P1 is uniform. For example, Figure 8 The diagram schematically shows that the light-blocking area P2 surrounds the light-transmitting area P1 circumferentially, and the light transmittance of the light-transmitting area P1 is uniform.
[0096] However, this disclosure is not limited to this. For example, the light transmittance of the light-transmitting area can also be set to be non-uniform. For example, the light transmittance of the light-transmitting area can gradually decrease from the edge away from the shading area to the edge closer to the shading area.
[0097] By setting the shape of the light-transmitting area and the relative position of the light-transmitting and light-blocking areas in the dimming pattern, information can be conveyed to the user using the dimming pattern. This will be explained in detail with the following example.
[0098] refer to Figure 1 Step S1 includes: acquiring a dimming control signal based on the user's dimming command. The dimming command includes at least one of a target voice command and a target gesture command. For example, the dimming command may only include a target voice command. For example, the dimming command may only include a target gesture command. For example, the dimming command may include both a target voice command and a target gesture command.
[0099] For example, if a user issues a target voice command, a dimming control signal can be determined based on the target voice command to cause the display screen to show the desired dimming pattern. For example, the target voice command may include keywords preset by the user.
[0100] refer to Figure 5For example, a user can preset the keyword "shooting mode" and a corresponding dimming pattern P. For example, the dimming pattern P corresponding to the keyword "shooting mode" may include a rectangular light-transmitting area P1. For example, the rectangular light-transmitting area P1 can be considered as a viewfinder in the shooting mode. For example, the viewfinder can dynamically change according to the user's gaze information, thereby achieving dynamic capture of the gazed object using the viewfinder.
[0101] Therefore, in shooting mode, the near-eye display device can use the light-transmitting area to define the range of the shooting scene, and can also provide composition assistance for the user's shooting process, providing the user with better visual guidance and immersive experience.
[0102] For example, users can preset the keyword "XX mode" and preset the dimming pattern corresponding to the keyword "XX mode".
[0103] refer to Figure 6 For example, the dimming pattern P corresponding to the keyword "XX mode" may include a triangular light-transmitting area P1. For example, the triangular light-transmitting area P1 can be used to indicate direction, thereby guiding the user's route. For example, in... Figure 6 In the center, the triangular light-transmitting area P1 points upwards, thus guiding the user forward. Of course, the shape of the light-transmitting area is not limited to this. Figure 6 The triangle shown can also be in the shape of a rhombus, an arrow, or something else, as long as the direction can be determined by the light-transmitting area. This disclosure does not impose any restrictions on this.
[0104] refer to Figure 7 For example, the dimming pattern P corresponding to the keyword "XX mode" may include a light-transmitting area P1 and a light-blocking area P2 located on one side of the light-transmitting area P1. For example, Figure 7 The diagram schematically illustrates a light-transmitting area P1 and a light-blocking area P2 arranged in the Y direction, with the light transmittance of the light-blocking area P2 gradually decreasing along the direction indicated by the arrow in the Y direction. Therefore, the relative positional relationship between the light-transmitting area P1 and the light-blocking area P2 can guide the user's direction of travel. For example, in... Figure 7 In the middle, the light-transmitting area P1 is located to the left of the light-blocking area P2, thus guiding the user to turn left.
[0105] For example, the target gesture instruction may include an instruction generated after a user performs a gesture on the near-eye display device. For instance, if the user's gesture on the near-eye display device is detected, a dimming control signal can be determined based on the gesture to cause the display screen to show the desired dimming pattern.
[0106] For example, users can pre-set a "grab" gesture and a dimming pattern corresponding to the keyword "grab". For example, the "grab" gesture could be the user's five fingers together. Of course, other gestures can also be set according to actual needs, and this disclosure does not limit them.
[0107] refer to Figure 8 For example, the dimming pattern P corresponding to the keyword "grab" could include a circular light-transmitting area P1. For instance, the circular light-transmitting area P1 could highlight objects within the area, making it easier for the user to focus on the object within P1 and reducing interference from other objects within the shaded area P2. For example, in... Figure 8 In the center of the screen, a circular light-transmitting area P1 is positioned to highlight objects in the user's field of vision. Of course, the shape of this light-transmitting area is not limited to this. Figure 8 The circle shown can also be a shape such as a rhombus, triangle, or rectangle, as long as the light-transmitting area can be used to obtain a highlight effect, and this disclosure does not limit it in this regard.
[0108] It is understood that the near-eye display device may also be equipped with modules such as touch sensors and voice sensors to detect and recognize the aforementioned target voice commands or target gesture commands, and this disclosure does not impose any restrictions on this.
[0109] Figure 9 A schematic diagram of a display screen in a near-eye display device displaying virtual information is provided in at least one embodiment of this disclosure.
[0110] refer to Figure 9 In some examples, the dimming method also includes displaying virtual information A on the display surface 1200 of the display screen 110 to provide more information to the user.
[0111] For example, near-eye display devices can connect wirelessly to other electronic devices to enable interaction between them. Taking a mobile phone as an example, when a user's phone receives a push notification, the near-eye display device can display virtual information on its screen to notify the user that their phone has received the notification.
[0112] For example, the wireless technology can be Bluetooth, Wi-Fi, or other wireless protocols to enable real-time and rapid interaction between the near-eye display device and other electronic devices. It is understood that this disclosure does not limit the specific implementation of the wireless technology, as long as it enables interaction between the near-eye display device and other electronic devices.
[0113] For example, Figure 9The illustration shows that the virtual information A is circular in shape. However, this disclosure is not limited to this; for example, the virtual information can also be other shapes. For example, the virtual information can also be such as numbers, letters, text, images, etc.
[0114] For example, the size of the virtual information and its display position on the display surface can be preset, and this disclosure does not impose any restrictions on this.
[0115] For example, virtual information can be displayed on the screen based on user display commands. These user display commands can be commands such as voice commands or gesture commands.
[0116] For example, Figure 9 The illustration schematically shows virtual information A in a dark state, and the area outside of virtual information A in a bright state. However, this disclosure is not limited to this. For example, the area outside of virtual information can be set to a dark state, and the virtual information can be set to a bright state, that is, the ambient light can be dimmed to make the virtual information stand out more. This helps to make the virtual information look more realistic.
[0117] For example, the dimming method provided in this disclosure can also dim based on conditions such as ambient light adaptation, dynamic dimming, and contrast enhancement.
[0118] For example, regarding ambient light adaptation, transmittance can be reduced in bright light environments (such as outdoors) to decrease glare and improve display contrast. Simultaneously, transmittance can be increased in low light environments (such as indoors) to enhance the user's environmental perception.
[0119] For example, regarding dynamic light attenuation, local dimming can be used to enhance the clarity of virtual information, thereby reducing the interference of ambient light on the displayed content.
[0120] For example, to enhance visual contrast, light intensity can be adjusted by regulating transmittance, thereby improving the readability of displayed content and optimizing the user experience.

These APIs allow developers to use specific functionalities. For instance, a developer can use an SDK to control an LCD to display different content (such as dimming patterns). Similarly, a controller can obtain external instructions or data through an API.
