Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a display device and a display control method. Background Technology

[0002] Currently, "bestie phones," as an emerging type of mobile smart terminal, typically integrate a large display screen, battery, and mobile stand, primarily for entertainment, fitness, and video calls. However, most existing products use traditional LCD screens as the display core. Structurally, the requirement for a backlight module results in a bulky device with a low screen-to-body ratio. Furthermore, the completely opaque screen obstructs the view behind the user, creating a visual disconnect between digital information and the real environment. In addition, these devices primarily focus on application-level software, lacking the ability to perceive and adapt to different usage scenarios. This leads to a high degree of homogenization in product form and experience, making it difficult to provide intelligent services tailored to specific scenarios.

[0003] The emergence of transparent OLED (Transparent Organic Light-Emitting Diode, T-OLED) display technology offers the possibility of improving the aforementioned problems due to its self-emissive, high-contrast, and high-transparency characteristics. However, current technologies simply integrate transparent OLEDs into mobile devices, failing to effectively resolve the inherent technical contradictions of transparent displays: namely, a significant decrease in transparency when displaying light-colored or white content, affecting the clarity of the view behind; and users have different needs for screen states in different usage scenarios, such as requiring a completely opaque immersive experience when watching movies, while wanting a highly transparent screen to observe the countertop when referring to recipes in the kitchen. Existing "best friend phones" cannot freely switch between "transparent" and "opaque" identities, thus failing to simultaneously meet these two mutually exclusive user experience needs on a single device. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a display device and a display control method to overcome at least one of the above-mentioned defects.

[0005] In a first aspect, embodiments of this application provide a display device, the device comprising: a transparent OLED display screen; an adjustable light-shielding layer, stacked on top of the transparent OLED display screen; and a control unit connected to the adjustable light-shielding layer; wherein the control unit controls the adjustable light-shielding layer to switch between a transparent state and an opaque state, thereby enabling the display device to switch between a transparent mode and an immersive mode.

[0006] In one optional embodiment of this application, an ambient light sensor is further included, which is connected to the control unit. The control unit is configured to: when the ambient light sensor is detected to be in an on state, determine whether the ambient light intensity detected by the ambient light sensor is greater than a preset threshold; if the ambient light intensity detected by the ambient light sensor is greater than the preset threshold, control the display device to be in an immersive mode, wherein the immersive mode indicates that the adjustable light-shielding layer is opaque; if the ambient light intensity detected by the ambient light sensor is not greater than the preset threshold, control the display device to be in a transparent mode, wherein the transparent mode indicates that the adjustable light-shielding layer is transparent.

[0007] In one optional embodiment of this application, a distance sensor is further included, which is connected to the control unit. The control unit is configured to: control the display device to switch to immersive mode when the distance sensor is turned on and detects that the user is within a preset distance; and control the display device to switch to transparent mode when the distance sensor is turned on and does not detect that the user is within the preset distance.

[0008] In one optional embodiment of this application, a protective glass is further included, which is disposed parallel to the transparent OLED display screen. The outline dimensions of the protective glass are adapted to the outline dimensions of the transparent OLED display screen. The adjustable light-shielding layer is disposed between the transparent OLED display screen and the protective glass, or the adjustable light-shielding layer is disposed on the side of the transparent OLED display screen opposite to the protective glass, forming a stacked structure.

[0009] In one optional embodiment of this application, a touch sensing layer is further included, the touch sensing layer being disposed on the side of the protective glass closer to the user, wherein the control unit is further configured to: adjust the voltage applied to the adjustable light-shielding layer in response to a manual command received via a touch interface or a physical button, and control the state switching of the adjustable light-shielding layer.

[0010] In one optional embodiment of this application, a sound pickup module is further included, which is connected to the control unit. The control unit is configured to: control the display device to switch to immersive mode when it detects that the voice information received by the sound pickup module contains a first keyword; and control the display device to switch to transparent mode when it detects that the voice information received by the sound pickup module contains a second keyword.

[0011] In one optional embodiment of this application, a gesture recognition module is further included. The gesture recognition module is connected to the control unit, wherein the control unit is configured to: when the gesture recognition module recognizes a first preset gesture, control the adjustable light-blocking layer to switch to an opaque state, thereby switching the display device to an immersive mode; and when the gesture recognition module recognizes a second preset gesture, control the adjustable light-blocking layer to return to a transparent state, thereby switching the display device to a transparent mode.

[0012] In one optional embodiment of this application, the control unit is further configured to: when it detects that the currently running application belongs to a first preset type, control the adjustable light-blocking layer to switch to an opaque state, wherein the first preset type is an audio-visual playback application; and when it detects that the currently running application belongs to a second preset type, control the adjustable light-blocking layer to switch to a transparent state, wherein the second preset type is an information browsing application or a video call application.

[0013] Secondly, embodiments of this application also provide a display control method applied to the display device described in any of the above claims. The method includes: detecting mode switching conditions; based on the mode switching conditions, controlling the application or cessation of applying a working voltage to an adjustable light-shielding layer to control the transparency state of the adjustable light-shielding layer; and switching the state of the adjustable light-shielding layer to enable the display device to switch between a transparent mode and an immersive mode.

[0014] In one optional embodiment of this application, the mode switching conditions include at least one of the following: ambient light intensity is greater than or lower than a preset threshold; a change in the distance relationship between the user and the display device is detected; voice information containing a first keyword or a second keyword is received; a first preset gesture or a second preset gesture of the user is recognized; and a currently running application of a preset type is detected.

[0015] The display device and display control method provided in this application embodiment dynamically adjust the transparency state of the light-shielding layer by the control unit, so as to realize the intelligent switching between transparent mode and immersive mode of the device, thus overcoming the technical problem that a single device cannot take into account both transparent display and immersive display.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0020] First, the applicable scenarios for this application will be introduced. This application can be applied to the field of display technology.

[0021] Research has found that "bestie phones," as a new type of mobile smart terminal in recent years, typically refer to touch-screen all-in-one devices integrating a large screen, battery, and mobile stand, used for entertainment, fitness, video calls, etc. Current technologies mostly rely on traditional LCD screens, which have the following inherent drawbacks: (1) Bulky form and lack of technological feel: LCD requires a backlight module, which makes the device bulky, with a low screen ratio and no transparent display, resulting in insufficient visual immersion and futuristic feel.

[0022] (2) Serious homogenization of functions: Most are enlarged versions of "tablet + stand", with functions concentrated at the App application layer, lacking the ability to deeply interact with the environment and users.

[0023] (3) Single interaction method: It mainly relies on touch and voice, lacks the perception and understanding of the scene, and cannot provide "proactive" intelligent services.

[0024] (4) Separation from the environment: When using an opaque screen, it will completely block the space behind it, making it impossible to present digital information and real-world scenes at the same time.

[0025] The emergence of transparent OLED (T-OLED) technology has provided a foundation for solving the above problems, possessing characteristics such as self-illumination, high contrast, and high transparency. However, simply integrating T-OLED into mobile devices has not fully realized its technological potential, nor has it creatively addressed the new challenges brought about by the integration of mobility, interactivity, and multiple functions.

[0026] Transparent screens perform exceptionally well when displaying dark content, but their transparency is somewhat affected when displaying light / white content. Users sometimes need an immersive experience with complete opacity (such as watching a movie), and at other times they need an environment blending experience with high transparency (such as viewing a kitchen countertop while browsing a recipe).

[0027] Based on this, embodiments of this application provide a display device and a display control method to solve the problem that existing display devices cannot dynamically switch between transparent mode and immersive mode.

[0028] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of the display device provided in the embodiments of this application. For example... Figure 1 As shown in the figure, the display device 10 provided in this application embodiment includes a protective glass 11, a touch sensing layer 12, an adjustable light-shielding layer 13, and a transparent OLED display screen 14.

[0029] The adjustable light-shielding layer 13 and the transparent OLED display screen 14 are stacked together.

[0030] The control unit is connected to the adjustable light-shielding layer 13; wherein the control unit controls the adjustable light-shielding layer 13 to switch between a transparent state and an opaque state, thereby enabling the display device 10 to switch between a transparent mode and an immersive mode.

[0031] The protective glass 11 is arranged parallel to the transparent OLED display 14, and the outline size of the protective glass 11 is adapted to the outline size of the transparent OLED display 14.

[0032] In the first embodiment, as Figure 1 The adjustable light-shielding layer 13 is disposed between the transparent OLED display screen 14 and the protective glass 11.

[0033] Alternatively, further, in the second embodiment, please refer to Figure 2 , Figure 2 This is one of the structural schematic diagrams of the display device provided in the embodiments of this application. For example... Figure 2As shown, the adjustable light-shielding layer 13 is disposed on the side of the transparent OLED display 14 away from the protective glass 11, forming a stacked structure.

[0034] The touch-sensitive layer 12 is disposed on the side of the protective glass 11 closer to the user. The control unit is also configured to adjust the voltage applied to the adjustable light-shielding layer in response to a manual command received via a touch interface or physical button, and to control the state switching of the adjustable light-shielding layer.

[0035] In the first embodiment, the structure consists of a protective glass (L1), a touch-sensing layer (L2), an adjustable light-shielding layer (L3), and a transparent OLED display (L4). The adjustable light-shielding layer 13 is in close contact with the transparent OLED display 14. When the adjustable light-shielding layer 13 is switched to an opaque state, it can serve as a direct, gapless background for the OLED pixels. This minimizes internal light reflection and scattering, resulting in purer blacks, higher contrast, and more vibrant and solid colors displayed in immersive mode, providing optimal visual immersion.

[0036] The fragile transparent OLED display 14 is placed in the innermost layer and protected by the outer protective glass 11 and the adjustable light-shielding layer 13, which reduces the risk of the OLED screen being damaged by direct impact or scratch.

[0037] In transparent mode, all layers (protective glass, touch layer, light-shielding layer, OLED screen) are transparent, giving users a sense of overall transparency from the surface, enhancing the sense of technology and unity.

[0038] In the second embodiment, the structure consists of a protective glass (L1), a touch-sensing layer (L2), a transparent OLED display (L4), and an adjustable light-shielding layer (L3). In transparent mode, the user's line of sight passes sequentially through the protective glass, the touch layer, and the transparent OLED screen, directly revealing the real world without any other optical layers in between. This provides potentially higher transparency and a more unobstructed field of view, resulting in a more realistic AR experience that blends the virtual and real worlds. This structure is also easier to implement. The transparent OLED display and the adjustable light-shielding layer can be assembled as two independent modules, reducing the difficulty of the full lamination process and potential yield losses. The adjustable light-shielding layer (especially PDLC) may generate heat during operation. Placing it at the rear facilitates heat dissipation to the back of the device, preventing heat accumulation inside the screen structure and affecting the performance and lifespan of the OLED screen.

[0039] Furthermore, an ambient light sensor is connected to a control unit, wherein the control unit is configured as follows: When the ambient light sensor is detected to be in the on state, it is determined whether the ambient light intensity detected by the ambient light sensor is greater than a preset threshold.

[0040] If the ambient light sensor detects an ambient light intensity greater than a preset threshold, the display device is controlled to enter immersion mode. Immersion mode indicates that the adjustable light-shielding layer is opaque.

[0041] If the ambient light intensity detected by the ambient light sensor is not greater than the preset threshold, the display device is controlled to be in transparent mode. Transparent mode indicates that the adjustable light-shielding layer is transparent.

[0042] When the ambient light is strong, the device automatically switches to immersive mode to ensure optimal display quality; when the ambient light is dim, it automatically switches to transparent mode to blend in with the environment. This logic simulates the natural needs of humans in different lighting conditions, thus achieving device intelligence.

[0043] Here, the material of the adjustable light-shielding layer can be a PDLC polymer-dispersed liquid crystal film or an EC electrochromic film.

[0044] In an optional embodiment, the adjustable light-shielding layer is specifically an electrochromic film.

[0045] The control unit is configured to: apply a DC operating voltage (e.g., +2V to +4V) to the electrochromic film when switching to immersion mode is required; and stop applying the operating voltage (i.e., the voltage is 0V) or apply a reverse voltage when switching to transparency mode is required.

[0046] EC membranes are electrochemical devices. When a positive voltage is applied, ions migrate within the membrane, causing a redox reaction that discolors the material and makes it opaque. When the voltage is turned off or a reverse voltage is applied, the ions migrate back, and the material fades and returns to a transparent state.

[0047] In another alternative embodiment, the adjustable light-shielding layer is specifically a polymer-dispersed liquid crystal film.

[0048] The control unit is configured to: stop applying a working voltage (i.e., 0V) to the polymer-dispersed liquid crystal film when it is necessary to switch to immersion mode; and apply an AC working voltage (e.g., AC 50V-100V) to the polymer-dispersed liquid crystal film when it is necessary to switch to transparent mode.

[0049] Here, in the power-off state, the liquid crystal molecules inside the PDLC film are arranged randomly, and light is scattered in large quantities, so the film appears opaque and milky white.

[0050] When a voltage is applied, the electric field causes the liquid crystal molecules to align in an orderly manner, allowing light to pass through directly, and the film instantly becomes transparent.

[0051] By introducing the aforementioned intelligent control logic based on ambient light sensors and combining it with adjustable shading technologies such as PDLC or EC, the embodiments of this application successfully resolve the fundamental technical contradiction of the inability to simultaneously achieve "transparent display" and "immersive display" on a single device, enabling the product to adapt to diverse application scenarios. The device no longer relies entirely on passive commands and can intelligently select the most suitable display mode by sensing ambient light, providing an "active" intelligent service experience and overcoming the shortcomings of existing technologies such as homogeneous functions and single interaction. Whether utilizing the low static power consumption of EC film or the high-speed response of PDLC film, the energy efficiency and user experience of the product are significantly improved.

[0052] Immersive Mode: Turns the adjustable light-blocking layer into an opaque milky white or dark color, acting as a "virtual background wall" for the transparent OLED display, providing deep blacks and vibrant colors indistinguishable from traditional screens, suitable for audio-visual entertainment.

[0053] Transparent Mode: The adjustable light-blocking layer restores high transparency, making objects behind the screen clearly visible, achieving an AR-like experience that combines virtual and real elements, suitable for information browsing, video calls, fitness guidance, etc.

[0054] The adjustable light-shielding layer consists of two layers of electrodes. Adjusting the voltage changes the voltage value between the electrodes, thereby further controlling the rotation angle of the internal liquid crystal and other polarized light materials, and controlling the degree of brightness and darkness of the product.

[0055] Specifically, it also includes a distance sensor connected to a control unit, wherein the control unit is configured to: When the distance sensor is on and detects that the user is within a preset distance, the control display device switches to immersive mode.

[0056] When the distance sensor is on and no user is detected within the preset distance, the control display device switches to transparent mode.

[0057] This implementation integrates a distance sensor (such as an infrared distance sensor or a time-of-flight sensor) into the display device. Its core control logic is as follows: when a user is detected within a preset distance, it automatically switches to immersive mode to provide a private and focused visual experience; when the user leaves and is no longer within the preset distance, it automatically switches to transparent mode, allowing the device to blend seamlessly with its environment. This logic endows the device with the ability to sense the user's presence, achieving a leap from "human-driven agility" to true "environmental awareness."

[0058] Here, the distance sensor continuously or intermittently detects whether there is an object within a certain conical area directly in front of it and measures the distance between the sensor and the object. The control unit compares the measured distance value with a preset distance (e.g., 0.5 meters to 1.5 meters, which can be adjusted according to the application scenario).

[0059] User Approach: When the sensor detects a user entering the preset distance range, the control unit determines that the user intends to operate or view the device and triggers a mode switch. It sends a command to the adjustable light-blocking layer, causing it to switch to an opaque state, thereby setting the entire display device to immersive mode.

[0060] User Departure: When the sensor detects that the user has left the preset distance range for a period of time (e.g., 3-5 seconds, to prevent false alarms), the control unit determines that the user has finished using the device. It then controls the adjustable light-shielding layer to switch to a transparent state, restoring the display device to transparent mode.

[0061] Scenario 1: A user walks towards the "best friend's phone" placed on the desk, ready to watch a video. When the user is half a meter away, the device senses the user, and the screen automatically switches to an opaque immersive mode. After the user leaves the desk, the device automatically returns to transparency, revealing the decorative items placed behind it.

[0062] Scenario 2: In the kitchen, a user stands in front of the device to view a complex recipe. The screen is in immersive mode to ensure clear text. When the user turns to retrieve ingredients from the refrigerator and leaves the detection range, the screen automatically becomes transparent, allowing a clear view of the entire countertop. Upon returning to the device after retrieving the ingredients, the screen automatically switches back to immersive mode.

[0063] In summary, by integrating a distance sensor and implementing the aforementioned control logic, this application transforms the display device from a passive tool into an intelligent environmental terminal capable of sensing context, proactively adapting, and providing privacy protection. This fundamentally solves the problem of the device being disconnected from its environment when not in use and enhances the naturalness and intelligence of the interaction.

[0064] Furthermore, it also includes a microphone module, which is connected to a control unit, wherein the control unit is configured as follows: When the voice information received by the microphone module is detected to contain the first keyword, the control display device switches to immersive mode.

[0065] When the voice information received by the microphone module is detected to contain a second keyword, the control display device switches to transparent mode.

[0066] This implementation integrates a sound pickup module (microphone array and related voice processing circuitry) into the display device. Its core control logic is that users can directly instruct the display device to switch between "immersive mode" and "transparent mode" by speaking specific, predefined voice keywords. This provides a hands-free, efficient, and direct natural interaction method.

[0067] The device has a built-in microphone module for capturing user voice. The voice processing chip inside the control unit or connected to it contains the voice recognition algorithm.

[0068] The system has two core voice commands pre-set: the first keyword is used to trigger "immersive mode". For example: "Turn on immersive mode", "Opaque screen", "I want to watch a movie".

[0069] The second keyword is used to trigger "transparency mode". For example: "Enable transparency mode", "Transparent screen", "Show background".

[0070] The voice pickup module continuously monitors ambient sounds. When it detects a voice that matches the wake-up characteristics, it begins recording and recognition. The acquired voice signal is converted into a digital signal and parsed by a voice recognition algorithm, which then matches it against a preset first and second keyword lexicon.

[0071] When the recognized voice command matches the first keyword, the control unit immediately sends a control signal to the adjustable light-shielding layer, switching it to an opaque state, and the entire display device enters immersive mode.

[0072] When the recognized voice command matches the second keyword, the control unit controls the adjustable light-shielding layer to switch to a transparent state, and the display device enters transparent mode.

[0073] This application, by integrating a voice pickup module and enabling voice control switching, not only improves the convenience and efficiency of operation, but also reflects the development of the device towards intelligent, natural, and humanized interaction. It solves the pain point of inconvenient touch and gesture interaction in specific scenarios, enabling the product to better integrate into diverse user life scenarios.

[0074] Specifically, it also includes a gesture recognition module, which is connected to a control unit, wherein the control unit is configured as follows: When the gesture recognition module detects the first preset gesture, it controls the adjustable light-blocking layer to switch to an opaque state, causing the display device to switch to immersive mode.

[0075] When the gesture recognition module detects a second preset gesture, it controls the adjustable light-blocking layer to return to a transparent state, causing the display device to switch to transparent mode.

[0076] This implementation integrates a gesture recognition module into the display device. Its core control logic is that users can control the display device to switch between "immersive mode" and "transparent mode" without contact by making specific, predefined gestures. This creates an intuitive and futuristic interactive experience.

[0077] The device integrates a gesture recognition module, which may include a time-of-flight sensor, a 3D camera, or a regular camera combined with visual algorithms. Time-of-flight (ToF) sensors are the preferred solution for achieving high-precision gesture recognition due to their ability to accurately capture depth information.

[0078] The system has two preset core gesture commands: The first preset gesture is used to trigger "immersive mode". For example, clenching a fist or swinging the palm inward. This gesture symbolizes "grabbing the content" or "blocking distractions".

[0079] The second preset gesture is used to trigger "transparency mode". For example, opening your palm or pushing your palm outward. This gesture symbolizes "open space" or "revealing the background".

[0080] The gesture recognition module continuously monitors the preset recognition area. When a hand is detected entering, it uses infrared light or image capture to build a depth model or skeletal model of the hand in real time. The algorithm extracts key features from the model (such as finger joint angles, palm orientation, and movement trajectory) and compares and matches them with the feature libraries of the first and second preset gestures.

[0081] When the recognized gesture matches the first preset gesture, the control unit sends a control signal to the adjustable light-shielding layer, causing it to switch to an opaque state, and the entire display device enters immersive mode.

[0082] When the recognized gesture matches the second preset gesture, the control unit controls the adjustable light-shielding layer to switch to a transparent state, and the display device enters transparent mode.

[0083] This application, by integrating a gesture recognition module, not only solves the pain points of interaction in specific scenarios (such as dirty hands or noisy environments), but more importantly, by creating a "hands-free control" experience, it significantly enhances the product's differentiated competitiveness and the user's enjoyment, making device interaction more natural and humanized.

[0084] In this embodiment of the application, the control unit is further configured to: When it is detected that the currently running application belongs to the first preset type, the adjustable light-blocking layer is controlled to switch to an opaque state. The first preset type is an audio-visual playback application.

[0085] When it is detected that the currently running application belongs to the second preset type, the adjustable light-blocking layer is controlled to switch to a transparent state. The second preset type is an information browsing application or a video call application.

[0086] The core control logic of this implementation is that the display device can intelligently identify the type of application currently running and automatically switch the screen to the display mode most suitable for the application's usage scenario. This achieves intelligent adaptive matching between device functions and display form without any manual intervention from the user.

[0087] Establish an application type library: Pre-define application type classification rules at the system level.

[0088] First preset type: Video and audio playback applications. Examples include: Tencent Video, iQiyi, YouTube, Netflix, local video players, etc.

[0089] The second preset type: Information browsing or video calling applications. Examples include: browsers, news apps, e-books, WeChat, Zoom, Skype, etc.

[0090] The control unit continuously monitors the identity of applications running in the foreground (such as application package name and process name); the system matches the currently running application with the preset type library to determine whether it belongs to the first preset type or the second preset type.

[0091] When a user launches an application identified as belonging to the first preset type (audio-visual playback), the control unit immediately (or when video playback is detected to begin) sends a command to the adjustable light-blocking layer, causing it to switch to an opaque state. At this time, the display device enters immersive mode, providing the user with a deep background and focused viewing environment similar to that of a movie theater.

[0092] When a user launches an application identified as belonging to the second preset type (information browsing or video call), the control unit switches the adjustable light-shielding layer to a transparent state. At this time, the display device enters transparent mode. For information browsing, users can see both the screen information and the real-world environment; for video calls, it allows for natural eye contact with the other party and allows them to see their surroundings, enhancing the sense of presence in the communication.

[0093] This application implements an automatic control strategy based on application type, ensuring perfect synergy between hardware capabilities and software services. This fundamentally enhances the practical value and intelligent image of the product, and is a key technological path to solve functional homogenization and achieve differentiated competition.

[0094] This application achieves automatic or manual switching between two modes by using ambient light sensor data or user voice (with a sound pickup module) / gesture commands (with a gesture recognition module, such as ToF), or by setting the underlying algorithm of the currently running application (such as automatically switching to immersive mode when launching the "iQiyi" APP).

[0095] This application integrates a display system that can dynamically switch between transparent and opaque states into a mobile phone, resolving the contradiction between transparent and immersive display in practical application scenarios, and enabling the product to achieve more diversified market applications.

[0096] The dual modes in this application refer to immersive mode (opaque state) and transparent mode (transparent state), with adjustable light-blocking layers (regardless of stacking structure). Figure 1 and structural form Figure 2The first is the hardware foundation for achieving dual modes (two stacked structures, the materials can be the same), and the second is the bridge between them, which is the sensor / voice pickup module / gesture module.

[0097] Please see Figure 3 , Figure 3 A flowchart illustrating the display control method provided in an embodiment of this application. Figure 3 As shown in the embodiments of this application, the display control method applied to any of the above-described display devices includes: S101, Detection mode switching conditions.

[0098] For example, mode switching conditions include at least one of the following: The ambient light intensity is greater than or less than a preset threshold; a change in the distance relationship between the user and the display device is detected; voice information containing a first keyword or a second keyword is received; the user's first preset gesture or second preset gesture is recognized; and a currently running application of a preset type is detected.

[0099] In this step, the control unit monitors the environment and user status in parallel through multiple sensing channels, specifically including: Ambient light monitoring: Ambient light intensity data is collected in real time by an ambient light sensor and compared with a preset threshold for judgment.

[0100] User distance perception: Detects the relative position of the user and the display device through a distance sensor.

[0101] Voice command recognition: The voice signal is received through the sound pickup module, and the keywords in it are parsed through the voice recognition algorithm.

[0102] Gesture motion capture: Captures user gestures through a gesture recognition module and identifies specific gestures through an image recognition algorithm.

[0103] Application monitoring: Monitors the types of applications currently running in the foreground via the operating system interface.

[0104] These detection conditions can work independently or in combination. The system uses "OR" logic for judgment, meaning that mode switching can be triggered when any condition is met.

[0105] This step establishes a complete environmental perception system, enabling the device to understand user needs from multiple dimensions such as light, distance, voice, and gestures; it provides sufficient decision-making basis for subsequent mode switching, ensuring that each mode switch has clear contextual rationality; different detection conditions are applicable to different usage scenarios, ensuring that appropriate interaction methods can be provided in various usage environments. S102. Based on the mode switching conditions, control the application or cessation of the working voltage to the adjustable light-shielding layer to control the transparency state of the adjustable light-shielding layer.

[0106] In this step, the control unit sends precise control commands to the adjustable light-shielding layer based on the detection results of S101: Voltage control strategy: When it is necessary to switch to immersion mode, depending on the type of adjustable light-shielding layer material: for PDLC film: stop applying the working voltage; for EC film: apply the working voltage.

[0107] When switching to transparent mode is required: For PDLC films: apply operating voltage; For EC films: stop applying operating voltage.

[0108] Intelligent priority handling: When multiple switching conditions are met simultaneously, the system can set priority logic, such as manual commands taking precedence over automatic detection.

[0109] This application provides precise voltage control for different material properties to ensure the reliability of state switching; it can automatically select the most suitable display mode according to different triggering conditions; and through precise voltage control, it avoids unnecessary energy consumption.

[0110] S103. By switching the state of the adjustable light-shielding layer, the display device is switched between transparent mode and immersive mode.

[0111] When the adjustable light-shielding layer is in a transparent state, the display device operates in transparent mode; when the adjustable light-shielding layer is in an opaque state, the display device operates in immersive mode.

[0112] In this step, when the adjustable light-shielding layer is in an opaque state, it provides a pure background for the transparent OLED display: completely blocking interference from objects behind it; providing a deep black background; and significantly improving contrast and color saturation.

[0113] When the adjustable light-blocking layer is in a transparent state: it maintains high screen transparency; it integrates digital information with the real scene; it eliminates visual obstruction and expands the sense of space.

[0114] This application provides visual performance comparable to traditional displays during audio-visual entertainment, maintains information interaction with the environment during information browsing and video calls, automatically adapts to different user needs, and provides optimal display effects.

[0115] The display device and display control method provided in this application innovatively combine a transparent OLED display screen with an adjustable light-shielding layer and introduce intelligent control logic based on multiple sensing conditions. This enables the display device to intelligently and dynamically switch between transparent mode and immersive mode, overcoming the shortcomings of existing display devices such as bulky form, homogeneous functions, single interaction and disconnection from the environment. It also solves the fundamental technical problem that transparent display technology and immersive visual experience are difficult to achieve on a single device.

[0116] This application uses a transparent OLED screen to integrate signal display driver / signal system / power supply system / related peripherals (camera / microphone / touch, etc.) and sensor devices (light sensor / distance detection, etc.) to realize a transparent mobile phone product solution. It combines an adjustable light-shielding layer with a transparent OLED product to achieve a "dual-mode" display system architecture.
