Detailed Implementation

[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0041] Foldable phones satisfy both the small-screen portability needs of smart mobile devices and the large-screen requirements of everyday office work, leading to their increasing application in consumer electronics. They have extremely high demands in terms of overall lifespan, camera imaging experience, and battery life. Current foldable phone solutions, based on the requirements of ultra-thin form factor and large battery capacity, typically place the camera and main chip on opposite sides of the folding hinge, connected by a flexible printed circuit board (FPC) across the hinge. This design has the following problems:

[0042] Because it crosses the hinge, it will be fully opened and closed by the user. After long-term and frequent bending, it is prone to reliability issues such as breakage, which will affect the lifespan of the folding device, as well as its functionality and user experience.

[0043] To minimize this impact, the number of connection pins between the camera module and the main chip is typically reduced in the early stages of design, thereby reducing FPC traces. A reduced pin count limits the camera's MIPI data transfer rate, which in turn affects the camera's resolution and frame rate, impacting camera functionality and user experience.

[0044] The screen module and mobile terminal of the present application are described below with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the structure of a screen module device provided in an embodiment of this application, as shown below. Figure 1 As shown, the screen module includes:

[0046] The first body 10 is equipped with a first optical communication module 11;

[0047] The second body 20 is rotatably connected to the first body 10. The second body rotates relative to the first body 10 to switch between an unfolded state and a folded state. The second body is provided with a second optical communication module 21.

[0048] The first optical communication module and the second optical communication module 21 are used to communicate in a wireless optical communication mode to transmit data between the first body 10 and the second body.

[0049] In this embodiment, the screen module includes a first body 10 and a second body. A first optical communication module is mounted on the first body 10. The second body is rotatably connected to the first body 10, allowing it to freely switch between an unfolded and folded state. A second optical communication module 21 is mounted on the second body. The first optical communication module 11 and the second optical communication module 21 communicate using a wireless optical communication mode, achieving efficient and stable data transmission between the first body 10 and the second body 20. This design abandons the traditional wired connection method, utilizing optical signals as the transmission medium. This not only improves the flexibility and reliability of the screen module during folding and unfolding, avoiding maintenance costs and usage risks caused by cable damage, but also provides more space for the thinner and smaller design of the device. Furthermore, the wireless optical communication mode has advantages such as high transmission speed and strong anti-electromagnetic interference capability, meeting the needs of modern electronic devices for high-speed and stable data transmission, and providing users with a smoother and more convenient user experience.

[0050] In one possible embodiment, the first body 10 and the second body 20 are rotatably connected by a pivot 40, which can be any of the following:

[0051] The teardrop-shaped hinge, by increasing the bending radius, reduces the pressure on the screen caused by folding, thus slowing down the deepening of creases. Its structure is relatively complex, typically composed of multiple layers and containing numerous precision parts, generally numbering 150-200 components, with some parts having a precision of up to 0.01 millimeters. This significantly reduces the difficulty of implementing foldable screens, lowers the requirements for the screen, and reduces stress concentration caused by mechanical movement, thereby improving the tightness and durability of the screen closure. It also effectively controls costs to some extent and allows the phone to achieve an almost completely closed state when folded, while also helping to improve the dust resistance of the device.

[0052] A U-shaped hinge, with a U-shaped shaft, is similar in shape to a teardrop hinge and also consists of multiple layers. However, compared to a teardrop hinge, it places higher demands on the screen, requiring a smaller bending radius when folded. This allows for a tighter folding effect, making the phone smaller and easier to carry when folded.

[0053] The keel hinge employs a multi-link design, such as a three-stage linkage hinge, with multiple movable joints. Through structural reconstruction, it significantly enhances the hinge's freedom of movement, perfectly conforming to the screen's curvature and firmly encasing the inner screen, transforming the inner screen from a "line contact" to a "surface contact." It supports large-angle free hovering, greatly improving the overall reliability and drop resistance of the device, extending its folding lifespan, and effectively preventing excessive deformation of the screen during drops, reducing the risk of screen damage.

[0054] A hinge-type swivel consists of two or more rotatable arms connected by a hinge, allowing the phone to rotate when folded and unfolded. It has a relatively simple structure, low cost, and enables basic folding functionality. The folding angle can be adjusted as needed, thus satisfying user habits to some extent.

[0055] Gear-type hinges utilize gear meshing to control the rotation angle. By precisely designing parameters such as the gear module and number of teeth, accurate control of the hinge's rotation angle can be achieved. This high precision in rotation angle control enables multi-angle hovering functionality, providing users with a more flexible experience. For example, users can watch videos and take photos even when the foldable phone is in a semi-folded state.

[0056] In one possible embodiment, a portion of the rotating shaft 40 is pre-defined as a light-guiding area for transmitting optical signals. No objects obstructing light are present within this light-guiding area, ensuring smooth transmission of the optical signal. Optionally, the light-guiding area can be a cavity, acrylic, glass, or other light-guiding materials.

[0057] In one possible embodiment, the outer shells of the first and second bodies have light-transmitting holes to allow light signals to be transmitted between the first and second bodies.

[0058] Optionally, the device further includes:

[0059] The light guide module 30 is disposed in the first body 10 and the second body 20, and is used to guide the optical signal to be transmitted between the first optical communication module 11 and the second optical communication module 21.

[0060] In this embodiment, the light guiding module is respectively disposed in the first body 10 and the second body 20. Its core function is to guide the optical signal to be transmitted accurately and efficiently between the first optical communication module 11 and the second optical communication module 21. In practical applications, optical signals are easily affected by various factors during transmission, such as scattering, refraction, and attenuation, which can lead to problems such as unstable signal transmission and data loss.

[0061] By incorporating a light guide module, optical signals can be effectively converged, guided, and shaped, ensuring accurate transmission from the transmitter to the receiver along a predetermined path. This significantly enhances the stability and accuracy of optical signal transmission. It's akin to laying a dedicated high-speed channel for the optical signal, reducing transmission loss and interference and ensuring data integrity. Whether the screen module is unfolded or folded, the light guide module 30 effectively maintains stable and reliable signal connections between optical communication modules, further optimizing the communication performance of the screen module in different states. This improves the user experience and operational efficiency of the device, providing strong technical support for the use of screen modules in various complex application scenarios.

[0062] Optionally, one of the first optical communication module 11 and the second optical communication module 21 serves as the transmitter of the optical signal, and the other of the first optical communication module 11 and the second optical communication module 21 serves as the receiver of the optical signal; the light guiding module 30 includes:

[0063] A first light guide module 31 is disposed in the first body 10, and the first light guide module 31 includes a first semi-transparent and semi-reflective surface;

[0064] The second light guide module 32 is disposed in the second body 20. The first light guide module 31 includes a second semi-transparent and semi-reflective surface. The first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321 are perpendicular to each other.

[0065] In the unfolded state, the light signals of the first light guide module 31 and the second light guide module 32 are opposite to each other, and the light signal emitted by the transmitter is transmitted through the first semi-transparent and semi-reflective surface and the second semi-transparent and semi-reflective surface so that the receiver receives the transmitted light signal.

[0066] In the folded state, the optical signals of the first light guide module 31 and the second light guide module 32 are parallel to each other. The optical signal emitted by the transmitter is reflected on the first semi-transparent and semi-reflective surface and the second semi-transparent and semi-reflective surface 321 so that the receiver receives the reflected optical signal.

[0067] Figure 2 This is a schematic diagram of the structure of a screen module provided in an embodiment of this application, as shown below. Figure 2 As shown, in this embodiment, the light guide module 30 includes a first light guide submodule 31 and a second light guide submodule 32, which are respectively disposed in the first body 10 and the second body 20. The first light guide submodule 31 has a first semi-transparent and semi-reflective surface 311, and the second light guide module 32 has a second semi-transparent and semi-reflective surface 321.

[0068] A semi-transparent, semi-reflective optical element is an optical component that allows light to pass through and reflect partially simultaneously. Its key lies in the design of the coating and the selection of materials. The following coatings can be used to achieve a semi-transparent, semi-reflective effect:

[0069] Metal thin film coatings commonly use metals such as aluminum (Al), silver (Ag), and chromium (Cr). Silver is often chosen due to its high reflectivity, but aluminum and chromium are also widely used due to their good optical properties and stability. Metal thin film coatings have high reflectivity and a certain degree of transmittance, enabling light segmentation. However, the optical properties of metal thin films are greatly affected by their thickness, and their reflection and transmission characteristics vary at different wavelengths.

[0070] Dielectric coatings, typically made of materials including silicon oxide (SiO2), titanium dioxide (TiO2), zirconium oxide (ZrO2), and aluminum oxide (Al2O3), can achieve desired optical properties through multilayer stacking. Dielectric coatings control light reflection and transmission through the interference effect of multilayer thin films. They possess high damage thresholds, good optical stability, and customizable spectral characteristics, enabling high-precision reflectance / transmittance ratios.

[0071] Metal-dielectric hybrid coatings combine a metal thin film and a dielectric thin film, for example, coating a dielectric layer (such as SiO2 or TiO2) on both sides of a metal layer (such as silver or aluminum). This type of coating combines the high reflectivity of the metal with the interference effect of the dielectric, achieving stable reflection and transmission characteristics over a wide wavelength range while reducing the thickness of the metal layer to improve transmittance.

[0072] Nanostructured coatings are structured surfaces created using nanotechnology, such as nanoparticles, nanopores, or nanopillars. These coatings can achieve a semi-transparent, semi-reflective effect by controlling the interaction of light with the nanostructure. They possess unique optical properties, such as high transmittance and high reflectance over a wide wavelength range, as well as good angular stability.

[0073] When the screen module is in the unfolded state, the light signals of the first light guide module 31 and the second light guide module 32 are opposite each other. At this time, the light signal emitted by the transmitter can be smoothly transmitted through the first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321. The light path of the light signal is straight, so that the receiver can clearly receive the transmitted light signal, thereby achieving efficient data transmission.

[0074] When the screen module is folded, the light signals of the first light guide module 31 and the second light guide module 32 are parallel to each other as the first body 10 and the second body 20 move together. The light signal emitted by the transmitter will be reflected by the first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321. The receiver can still accurately receive the reflected light signal, ensuring the continuity and stability of data transmission.

[0075] Optionally, the first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321 are perpendicular to each other, which ensures that the light signal emitted from the transmitter can be parallel to the light signal emitted from the transmitter after being reflected by the first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321, thus ensuring that the light signal can enter the receiver.

[0076] In one possible embodiment, the first semi-transparent and semi-reflective surface 311 forms a 45° angle with the optical signal emitted by the transmitter, the first semi-transparent and semi-reflective surface 311 and the second semi-transparent and semi-reflective surface 321 are perpendicular to each other, and the second semi-transparent and semi-reflective surface 321 forms a 45° angle with the optical signal received by the receiver.

[0077] This ingenious optical structure design fully utilizes the transmission and reflection characteristics of a semi-transparent, semi-reflective surface. It automatically adjusts the transmission path of the optical signal according to different physical states of the screen module, eliminating the need for additional mechanical adjustments or complex control operations. This achieves seamless switching between the unfolded and folded states of the optical communication module. This not only improves the overall integration and reliability of the screen module but also significantly enhances the adaptability and flexibility of optical signal transmission, ensuring high efficiency and stability of data transmission in different usage scenarios. It provides important innovative ideas and technical support for the development of optical communication technology in new electronic devices such as foldable screens.

[0078] Optionally, the first light guide submodule 31 further includes a first blocking unit 312 and a first driving unit 313, and the second light guide submodule 32 further includes a second blocking unit 322 and a second driving unit 323;

[0079] The first driving unit 313 is used to drive the first blocking unit 312 away from the first semi-transparent and semi-reverse surface 311 in the unfolded state; and to drive the first blocking unit 312 to cover the first semi-transparent and semi-reverse surface 311 in the folded state.

[0080] The second driving unit 323 is used to drive the second blocking unit 322 away from the second semi-transparent and semi-reverse surface 321 in the unfolded state; and to drive the second blocking unit 322 to cover the second semi-transparent and semi-reverse surface 321 in the folded state.

[0081] Figure 3This is a schematic diagram of the structure of a screen module provided in an embodiment of this application, as shown below. Figure 3 As shown, in this embodiment, when the screen module is in the unfolded state, the first driving unit 313 can drive the first blocking unit 312 away from the first semi-transparent and semi-reflective surface 311, and drive the second blocking unit 322 away from the second semi-transparent and semi-reflective surface 321. This design ensures that the semi-transparent and semi-reflective surface does not obstruct the light path in the unfolded state, providing a direct channel for the transmission of light signals and ensuring that the light signals can be transmitted normally between the two light guide sub-modules and accurately received by the receiver.

[0082] When the screen module is folded, the first driving unit 313 drives the first blocking unit 312 to block the first semi-transparent and semi-reflective surface 311. Similarly, the second driving unit 323 drives the second blocking unit 322 to cover the second semi-transparent and semi-reflective surface 321. The main purpose of this design is to allow the semi-transparent and semi-reflective surfaces to reflect as much light as possible when folded. Since the semi-transparent and semi-reflective surfaces allow some light to pass through and reflect some light, when the screen module is folded, the light signal loses some power during reflection from the first and second semi-transparent and semi-reflective surfaces 311 and 321. By blocking the first and second semi-transparent and semi-reflective surfaces 311 and 322, the light signal that should have passed through can be reflected back, reducing power loss and improving the reliability of optical communication.

[0083] Optionally, the surfaces of the first shielding unit 312 and the second shielding unit 322 may be coated with at least one of the following coatings:

[0084] Aluminum Coating: Aluminum is a commonly used coating material for the back of mirrors due to its high reflectivity, relatively low cost, and good corrosion resistance and processing performance. An aluminum coating can be applied to the surface of an object using a vacuum metallization process, forming a uniform aluminum film with excellent reflective and protective properties.

[0085] Silver coating: Silver has a very high reflectivity, reaching over 90%. However, silver is expensive and easily oxidizes and discolors, requiring a protective layer to prevent oxidation. It can be used in special scenarios where extremely high reflectivity is required.

[0086] Chromium coating: Chromium coating has good reflective properties and corrosion resistance, and its high hardness provides a certain degree of wear protection. It is often used to manufacture high-quality mirrors, especially in applications requiring long service life and good durability, such as car rearview mirrors.

[0087] Metal-dielectric hybrid coatings combine the high reflectivity of metals with the optical properties and stability of dielectrics. For example, coating the surface of a metal layer (such as aluminum or silver) with one or more layers of dielectric materials, such as silicon dioxide (SiO2) or titanium dioxide (TiO2), can further improve the mirror's reflectivity, optimize spectral characteristics, and enhance the coating's durability and scratch resistance. By precisely controlling the thickness and combination of the metal and dielectric layers, coatings tailored to specific optical requirements can be created.

[0088] Dielectric coatings achieve desired optical properties primarily through the interference effect of multilayer thin films. Common dielectric materials include silicon oxide (SiO2), titanium dioxide (TiO2), and zirconium oxide (ZrO2). These materials can be stacked into multilayer structures to form coatings with specific reflectivities and transmittances. For example, by designing the thickness and sequence of dielectric layers with different refractive indices, high reflectivity or high transmittance can be achieved over a wide wavelength range, while also controlling optical properties such as polarization. Dielectric coatings offer advantages such as high damage thresholds and good optical stability, and are commonly used in high-precision optical mirrors, such as laser mirrors and astronomical telescope lenses. However, their fabrication process is relatively complex and costly.

[0089] Whether in complex indoor lighting environments or outdoor usage scenarios, it can minimize the impact of ambient light on optical signal transmission, ensuring that the data transmission performance of the screen module remains at its best in both unfolded and folded states, thus enhancing the adaptability and robustness of the screen module in practical applications.

[0090] Optionally, the terminal further includes:

[0091] The sensor module 50 is connected to the first optical communication module 11; the first optical communication module 11 is used to convert the electrical signal sent by the sensor module into an optical signal.

[0092] In this embodiment, a sensor module is introduced and connected to the first optical communication module 11. Sensor modules play a crucial role in modern electronic devices, capable of sensing various physical, chemical, or biological quantities in real time and converting them into electrical signals. In this screen module, the sensor module may include, but is not limited to, ambient light sensors, pressure sensors, temperature sensors, and proximity sensors.

[0093] By connecting the sensor module to the first optical communication module 11, the electrical signals collected by the sensor module can be efficiently converted into optical signals for transmission via the first optical communication module 11. This design is significant. On the one hand, the introduction of the sensor module enriches the functionality of the screen module, enabling it not only to function as a display device but also to perceive information such as the surrounding environment and the user's operating status in real time, and to quickly and accurately transmit this information to other relevant modules or devices for processing and analysis. For example, in a foldable phone, the ambient light sensor can monitor the ambient light intensity in real time and transmit the signal to the processor via the optical communication module. The processor automatically adjusts the screen brightness based on the received signal, thereby achieving intelligent dimming, which improves the user's visual experience and reduces the device's power consumption. On the other hand, using the optical communication module for sensor signal transmission has advantages such as high transmission speed, strong anti-electromagnetic interference capability, and high signal integrity. It ensures that the weak signals collected by the sensor are not affected by external interference during transmission, maintaining the original characteristics and accuracy of the signal. This provides a high-quality signal source for the intelligent control and data processing of the device, further enhancing the application value and user experience of the screen module in smart terminal devices.

[0094] Optionally, the terminal further includes:

[0095] Processor 60, which is connected to the second optical communication module 21, is used to process data received via optical signals;

[0096] The second optical communication module 21 is used to convert the electrical signal sent by the processor into an optical signal.

[0097] In this embodiment, the processor, as the core component, is responsible for performing complex calculations, processing, and analysis on various data. However, traditional data transmission methods often suffer from problems such as transmission speed bottlenecks and electromagnetic interference when connecting the processor to external modules, which affect the processor's performance and data processing efficiency.

[0098] This design achieves efficient bidirectional data transmission through the close integration of the optical communication module and the processor. When receiving data, the second optical communication module 21 rapidly converts the received optical signal into an electrical signal and transmits it to the processor for processing. The processor can analyze, calculate, and make decisions on the received data immediately, significantly shortening the data processing response time and improving the real-time performance of the device. When sending data, the processor converts the processed electrical signal back into an optical signal via the second optical communication module 21 for transmission. The high-speed transmission characteristics of optical signals ensure that the data output by the processor can be quickly and accurately transmitted to the target module or device, achieving efficient data interaction. This integration fully leverages the advantages of the optical communication module, not only improving the data transmission rate and quality between the processor and the optical communication module but also enhancing the overall performance and intelligence of the device. This allows the screen module to better collaborate with other devices, meeting the high-performance and multi-functional requirements of modern electronic devices. It provides a solid technical foundation for complex multi-device collaborative work and intelligent control scenarios, further expanding the application areas and market prospects of the screen module.

[0099] Optionally, the first optical communication module 11 includes a first optical transmitting module and a first optical receiving module;

[0100] The first optical transmitting module is used to transmit optical signals;

[0101] The first optical receiving module is used to receive optical signals.

[0102] In this embodiment, the first optical transmission module focuses on transmitting optical signals. It can efficiently convert electrical signals into optical signals and transmit them through a specific optical interface or path, ensuring that the transmission strength, frequency, wavelength, and other parameters of the optical signal meet communication standards and requirements. It employs advanced signal modulation technology and optical transmitting devices, such as laser diodes or light-emitting diodes, to achieve high-speed and stable optical signal transmission.

[0103] Meanwhile, the first optical receiving module is specifically designed to receive optical signals. It is equipped with highly sensitive photodetectors, such as photodiodes, capable of accurately capturing weak optical signals and converting them into electrical signals. The optical receiving module also incorporates signal amplification, filtering, and demodulation circuits to process the converted electrical signals, eliminating noise interference, restoring the original data signal, and ensuring the integrity and accuracy of the received data.

[0104] By dividing the first optical communication module 11 into independent transmitting and receiving sections, bidirectional data transmission is achieved. In screen module application scenarios, such as between the inner and outer screens of dual-screen interactive devices or foldable phones, data interaction is bidirectional. The first optical transmitting module can send locally generated data, such as user-inputted commands and updated display content, to the other optical communication module; simultaneously, the first optical receiving module can also receive data carried by the optical signals from the other party, such as sensor data and processor-processed results. This enables real-time, bidirectional data flow between the two entities, improving the communication flexibility and interactivity of the screen module. It better meets various complex application scenarios and user needs, providing strong support for the multifunctionality and intelligent development of the device.

[0105] Optionally, the second optical communication module 21 includes a second optical transmitting module and a second optical receiving module;

[0106] The second optical transmission module is used to transmit optical signals;

[0107] The second optical receiving module is used to receive optical signals.

[0108] In this embodiment, the second optical transmitting module functions similarly to the first optical transmitting module, responsible for converting electrical signals into optical signals and transmitting them. Based on the specific communication requirements of the device where the screen module is located, it employs appropriate optical transmitting devices and signal modulation techniques to ensure that the emitted optical signal has sufficient strength and stability, maintaining good signal quality within the specified transmission distance. The second optical receiving module is specifically responsible for receiving optical signals. Through a high-sensitivity photodetector and advanced signal processing circuitry, it converts the received optical signals into electrical signals and performs amplification, filtering, demodulation, and other processing to extract valid data information.

[0109] This independent transmit and receive module design enables the second optical communication module 21 to achieve bidirectional data transmission, forming an efficient communication link with the first optical communication module 11. In practical applications, such as in foldable laptops, the two bodies of the screen module serve as the display screen and keyboard area, respectively. The second optical transmit module can convert the electrical signals input from the keyboard into optical signals and send them to the display screen body. After receiving the optical signals, the display screen body uses the first optical receive module to restore them to electrical signals and display the corresponding character content. At the same time, the first optical transmit module of the display screen body can also send data generated by screen touch operations to the second optical receive module of the keyboard body, realizing bidirectional data interaction. This bidirectional communication capability greatly enhances the applicability and practicality of the screen module in different usage scenarios, ensures that data can flow efficiently and stably between the two bodies, improves the overall performance of the device and the user experience, and lays a solid foundation for the widespread application and technological innovation of screen modules.
