After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.
[0055] Please refer to Figure 1-2 This utility model provides a dual-view EL (Electroluminescent) display device, including an EL display panel 1 and a LENS structure 2; wherein,
[0056] The LENS structure 2 is precisely positioned on one side of the EL display panel 1 in the display direction, and combined with it in a specific spatial relationship to jointly construct a complete display function system;
[0057] The two opposing surfaces of the LENS structure 2 exhibit a unique geometric shape with continuous wave-like patterns. This special surface structure design endows the LENS structure 2 with unique optical properties and functional characteristics.
[0058] The dual-view EL display device proposed in this embodiment cleverly achieves the innovative function of dual-view display by carefully setting a LENS structure 2 with a continuous wave-shaped surface on one side of the EL display panel 1 in the display direction. This technological breakthrough is of great significance for effectively solving the limitations of existing vehicle displays in terms of functional design and target audience. Specifically, in the application scenarios of traditional vehicle displays, it is often difficult to meet the different usage needs of the driver and the front passenger, resulting in a significant limitation on the front passenger's entertainment experience during the ride. However, the dual-view EL display device designed in this invention, with its special design of the LENS structure 2, allows the display screen to present drastically different content from different viewing angles.
[0059] For drivers, this device precisely meets their need for clear and accurate display of driving-related information. During driving, drivers can obtain key driving data such as vehicle status, navigation information, and road condition alerts from a specific perspective, ensuring the safety and accuracy of driving operations. For the passenger, the device provides an independent and high-quality entertainment experience. Instead of sharing the same screen with the driver, the passenger can adjust their viewing angle to enjoy a variety of entertainment content, including music playback, streaming video, and games, greatly enriching their leisure time during the journey.
[0060] Through the unique optical design of the LENS structure 2, the display screen achieves dual-view functionality for both the driver and front passenger. This innovative design not only plays a crucial role in ensuring driving safety, allowing the driver to focus on driving information and reducing distractions caused by operating the display screen, but also significantly enhances the in-car entertainment experience for the front passenger, improving the overall user experience and comfort of the vehicle. In the long run, the promotion and application of this technology is expected to drive the further development of vehicle display technology, bringing more intelligent and user-friendly display solutions to the automotive industry.
[0061] Please refer to this again. Figure 2 In one embodiment of this invention, the two opposing surfaces of the LENS structure 2 exhibit a unique continuous wave-like shape composed of several closely connected arcs. Specifically, the endpoint of each arc is precisely connected to the endpoint of the adjacent arc. This design not only ensures the continuity and smoothness of the LENS structure 2 surface but also endows it with unique optical properties and functional advantages.
[0062] In terms of optical performance, the continuous wavy surface formed by the connecting arc ends allows for complex refraction and reflection of light as it passes through the LENS structure 2. This optical effect not only enhances the focusing ability of light and improves the clarity and brightness of the displayed image, but also provides a crucial optical foundation for achieving dual-view display functionality. By precisely controlling the radius, curvature, and connection angle between adjacent arcs, the optical performance of the LENS structure 2 can be further optimized, enabling it to present different display effects from different viewing angles.
[0063] In terms of functionality, the unique design of the LENS structure 2 allows the dual-view EL display to present clear and independent content from both the driver's and passenger's perspectives. For the driver, the display primarily focuses on driving-related information such as vehicle speed, navigation prompts, and road condition warnings, ensuring the safety and accuracy of driving operations. For the passenger, by adjusting their viewing angle, they can enjoy entertainment content entirely different from the driver's perspective, such as music playback, streaming video, and games, greatly enriching the leisure experience during the ride.
[0064] Furthermore, the continuous wave-shaped design of the LENS structure 2 also provides a certain degree of structural stability and durability. The circular arc-shaped connection method allows the LENS structure 2 to better disperse stress when subjected to external forces, reducing structural damage caused by stress concentration. At the same time, this design also helps to improve the impact resistance of the LENS structure 2, enabling it to maintain a stable display effect in complex and changing driving environments.
[0065] In summary, the two opposing surfaces of LENS structure 2 adopt a continuous wave-shaped design composed of several connected arcs, which not only realizes the dual-view display function, but also optimizes optical performance and enhances structural stability and durability.
[0066] Please refer to Figure 3 In one embodiment of this invention, the dual-view EL display device further includes a key component called driver 3.
[0067] The driver 3 and the EL display panel 1 are tightly coupled through a specialized electrical connection method. This electrical connection is not a simple physical contact, but is based on a specific circuit design and signal transmission protocol, designed to ensure that the driver 3 can efficiently and stably transmit various control signals and power supply to the EL display panel 1.
[0068] As the core control unit of the dual-view EL display device, driver 3 plays a crucial role. It can not only precisely control key display parameters such as brightness, color saturation, and contrast of the EL display panel 1 to achieve the best visual presentation effect, but also flexibly switch the display mode of the EL display panel 1 according to the needs of the actual application scenario, such as single-view display mode and dual-view display mode.
[0069] In dual-view display mode, the driver 3, through complex signal processing algorithms and precise timing control, ensures that the EL display panel 1 presents clear, independent, and non-interfering display content from both the driver and passenger viewing angles. Specifically, the driver 3 performs real-time segmentation and processing of the input video signal based on preset viewing angle parameters and display content, generating two different display data streams, which are then transmitted to the corresponding display areas of the EL display panel 1. Simultaneously, the driver 3 performs necessary preprocessing and correction of the display data streams based on the optical characteristics of the LENS structure 2 to ensure accurate and clear display effects from different viewing angles.
[0070] Furthermore, Driver 3 boasts strong compatibility and scalability. It can seamlessly interface with various signal sources, such as in-vehicle entertainment systems, navigation systems, and intelligent driving assistance systems, enabling integrated display and interactive control of various information. Simultaneously, with continuous technological development and upgrades, Driver 3 can continuously introduce new features and optimized algorithms through software upgrades or hardware expansions to meet increasingly diverse application needs.
[0071] In summary, the addition of driver 3 provides powerful power support and intelligent control capabilities for the dual-view EL display device, resulting in significant improvements in display performance, functional characteristics, and user experience.
[0072] Please refer to Figure 4 In one embodiment of this example, the dual-view EL display device is further optimized by adding a touchpad 4 as a key interactive component.
[0073] The touchpad 4 is carefully positioned on the side of the LENS structure 2 away from the EL display panel 1. This layout design fully considers the convenience and rationality of human-computer interaction. The touchpad 4 and the LENS structure 2 are tightly integrated through a specific installation process and structural fixing method, which not only ensures the stability and reliability of the touchpad 4, but also ensures that the optical synergy between it and the LENS structure 2 is not affected.
[0074] As a crucial interactive interface for the dual-view EL display device, the touchpad 4 plays a key role in facilitating information transmission and command input between the user and the device. It employs advanced touch technology and a high-sensitivity sensor, enabling it to capture user touch actions and gestures in real time and accurately, converting them into corresponding electrical signals that are then transmitted to the driver 3 for processing.
[0075] In dual-view display mode, the addition of touchpad 4 provides users with a more intuitive and convenient operating experience. The driver and front passenger can independently interact with the content displayed from their respective perspectives using touchpad 4. For example, the driver can quickly switch navigation interfaces, adjust driving parameters, or answer phone calls using touchpad 4; while the front passenger can browse entertainment programs, control music playback, or play games. This partitioned touch control design not only avoids operational interference between the driver and front passenger but also improves the efficiency and accuracy of interactive operations.
[0076] Furthermore, the touchpad 4 boasts a high degree of customizability and expandability. Depending on the specific application scenario and user needs, the touchpad 4's touch area, touch sensitivity, and gesture recognition algorithm can be customized and optimized. Simultaneously, with continuous technological development and upgrades, the touchpad 4 can be combined with other interactive technologies such as voice recognition and gesture recognition to form a more diversified and intelligent interactive system.
[0077] In conclusion, the addition of touchpad 4 significantly enhances the interactive capabilities of the dual-view EL display device, resulting in substantial improvements in user experience, ease of operation, and functional expandability. This innovative design not only meets users' demands for intelligent and convenient interactive experiences but also opens up new directions for the development of vehicle display technology.
[0078] Please refer to Figure 5 In one embodiment of this invention, the dual-view EL display device further optimizes the protection system by adding a key protective component, a protective film 5.
[0079] The protective film 5 is precisely covered on the outer surface of the touchpad 4. This layout design aims to provide the touchpad 4 with all-round, multi-layer protection. The protective film 5 and the touchpad 4 are tightly bonded through a specific bonding process and material selection, which ensures both the flatness and transparency of the protective film 5 and the touch sensitivity between it and the touchpad 4.
[0080] As a crucial protective barrier for the dual-view EL display device, the protective film 5 plays a vital role in resisting external physical damage, chemical corrosion, and environmental erosion. It is made of high-strength, high-toughness materials, possessing excellent scratch resistance, impact resistance, and wear resistance. Simultaneously, the protective film 5 also features anti-fingerprint and anti-glare functions, effectively reducing dirt residue and light reflection on the touchpad 4 surface, thus improving user visual comfort under various lighting conditions.
[0081] In dual-view display mode, the addition of the protective film 5 provides a safer and more reliable operating environment for the touchpad 4. Whether the driver performs rapid touch operations while driving or the passenger engages in prolonged touch interactions during leisure and entertainment, the protective film 5 can effectively resist various accidental damage and wear, ensuring the long-term stable operation and touch accuracy of the touchpad 4.
[0082] In addition, the protective film 5 is easy to clean and replace. When stains or scratches appear on the surface of the protective film 5, users can restore its original clarity and appearance through simple cleaning. When the protective film 5 ages or is damaged due to long-term use, users can easily replace it with a new protective film without disassembling or repairing the entire dual-view EL display device.
[0083] In summary, the addition of the protective film 5 enhances the protection of the dual-view EL display device, significantly improving its durability, reliability, and user experience. This innovative design not only extends the lifespan of the touchpad 4 but also reduces maintenance costs and usage risks for users.
[0084] Please refer to Figure 6 In one embodiment of this invention, the protective film 5 adopts an innovative multi-layer composite structure design, which aims to comprehensively improve the overall performance of the protective film 5 and provide a more superior protective effect for dual-view EL display devices.
[0085] Specifically, the multi-layer composite structure of the protective film 5 includes two core parts: a base layer 501 and a functional layer 502. The base layer 501, as the basic support layer of the entire protective film 5, is made of high-strength and high-toughness materials and has excellent tensile and bending resistance, providing a stable attachment platform for the functional layer 502.
[0086] The functional layer 502 is carefully positioned on top of the base layer 501. Through specific processes and material selection, it integrates and optimizes multiple functions. From bottom to top, the functional layer 502 includes an anti-blue light coating 5021, an anti-reflective layer 5022, and an oleophobic layer 5023. Each layer undertakes a specific functional task, together forming the multifunctional protective system of the protective film 5.
[0087] The anti-blue light coating 5021 is located at the bottom of the functional layer 502, closely attached to the base layer 501. This coating employs advanced blue light filtering technology, effectively absorbing and reflecting blue light wavelengths to reduce eye strain and provide users with a healthier and more comfortable visual experience. Especially during prolonged use of dual-view EL displays, the anti-blue light coating 5021 significantly reduces eye strain from blue light, protecting the user's visual health.
[0088] The anti-reflective layer 5022 is located on top of the anti-blue light coating 5021. It uses special anti-reflective materials and processes to effectively reduce the reflection and scattering of external light on the surface of the protective film 5, thereby improving the display clarity and readability of the dual-view EL display device under various lighting conditions.
[0089] The oleophobic layer 5023, as the outermost layer of the functional layer 502, is made of a highly oleophobic material. It effectively prevents fingerprints, oil stains, and other contaminants from adhering to and remaining on the surface of the protective film 5, maintaining its cleanliness and aesthetics. Simultaneously, the oleophobic layer 5023 also possesses excellent self-cleaning properties, reducing touch sensitivity issues caused by hand oils and stains, ensuring smoothness and accuracy for users during touch operations.
[0090] Through this multi-layered composite protective film 5 design, the dual-view EL display device not only provides dual-view display functionality but also further ensures user experience and health safety. The protective film 5 not only provides physical protection for the touchpad 4 but also optimizes the performance of the dual-view EL display device in different environments through its special functional layer 502 design, significantly improving the overall user experience and comfort of the vehicle.
[0091] In one embodiment of this invention, the dual-view EL display device further integrates an integrated controller, which serves as the core control hub of the device, enabling efficient collaborative management of display logic and drive signals.
[0092] The controller establishes a bidirectional communication link with the EL display panel 1 and the driver 3 through a sophisticated electrical connection architecture. Its hardware interface employs high-speed serial bus protocols (such as MIPI DSI, eDP, etc.) to ensure real-time and stable transmission of display data and control commands. At the software level, the controller incorporates a dual-core processor architecture, where the primary core runs the display control algorithm based on an RTOS (Real-Time Operating System), while the secondary core focuses on timing management and signal modulation of the driver 3.
[0093] This controller has three core functional modules:
[0094] (1) Multi-mode display scheduling engine: By parsing the composite video stream from the in-vehicle infotainment system (IVI) and combining the optical parameters of LENS structure 2, dynamic content separation of the driver's and passenger's perspectives is achieved. The spatial light modulation (SLM) algorithm is used to encode the perspective of the original image, generating two independent sub-frame data streams, corresponding to the driver's driving information interface and the passenger's entertainment content interface, respectively.
[0095] (2) Adaptive brightness adjustment system: Integrates an ambient light sensor and a vehicle status monitoring module to acquire parameters such as ambient light intensity, vehicle speed, and battery power in real time. Based on a fuzzy PID control algorithm, it dynamically adjusts the luminous intensity of the EL display panel 1 and the power supply voltage of the driver 3, achieving energy consumption optimization of more than 20% while ensuring display clarity.
[0096] (3) Intelligent Touch Collaboration Module: It establishes low-latency communication with the touchpad 4 via the I2C bus and uses machine learning algorithms to analyze the touch trajectory in real time. When a multi-finger gesture is detected, the dual-screen interaction mode is automatically triggered. For example, in a navigation scenario, the passenger can mark points of interest on the touchpad 4, and route planning suggestions are displayed on the driver's screen simultaneously.
[0097] In terms of safety redundancy design, the controller adopts a dual-channel power architecture and a watchdog timer. When a system anomaly is detected, it can automatically switch to the backup power supply and trigger a hardware reset. Meanwhile, its firmware supports OTA (over-the-air) upgrades, allowing it to receive algorithm update packages pushed from the cloud via the in-vehicle T-BOX module, continuously optimizing display effects and interactive experience.
[0098] The introduction of this controller enables dual-view EL display devices to break through the functional boundaries of traditional in-vehicle displays, achieving an intelligent leap from passive display to active interaction. Through collaborative hardware and software design, it not only meets the core requirements of intelligent cockpits for multi-view display, low-power operation, and high-reliability operation, but also lays a solid technical foundation for the innovative development of future in-vehicle HMI (Human-Machine Interface) systems.
[0099] In one embodiment of this invention, to further enhance the functionality and intelligence of the dual-view EL display device, a storage module is specially added as the core component for data storage and management.
[0100] The storage module and the controller are tightly electrically connected via a high-speed data bus, establishing an efficient data interaction channel. This connection method not only ensures the stability and real-time performance of data transmission but also provides a solid hardware foundation for subsequent complex data processing and computation. The storage module adopts advanced solid-state storage technologies, such as eMMC or UFS storage chips. Compared with traditional storage media, it has higher read and write speeds, lower power consumption, and stronger shock and vibration resistance, perfectly adapting to the stringent reliability requirements of the automotive environment.
[0101] In terms of functionality, the storage module undertakes the multi-dimensional storage task of the content displayed on the EL display panel 1. On one hand, as a local cache, it can temporarily store the image data to be displayed, video streams, and various interactive commands received from the controller. During vehicle operation, when the network connection is unstable or there is a brief data transmission delay, the storage module can respond quickly, retrieve data from the cache, and ensure that the display content of the EL display panel 1 does not experience stuttering, screen tearing, or other phenomena, providing users with a smooth and stable visual experience.
[0102] On the other hand, the storage module also features long-term data storage capabilities. It can save user-defined display settings, such as brightness adjustment parameters, color mode preferences, and dual-view display mode switching habits. When the user restarts the vehicle, the controller can automatically read these personalized settings from the storage module and quickly apply them to the EL display panel 1, achieving convenient "out-of-the-box" operation. Furthermore, the storage module can also securely store important driving information, navigation records, and multimedia content, allowing users to easily access and play them back at any time.
[0103] To meet the data storage needs of different application scenarios, the storage module adopts a flexible partitioning management strategy. The storage space is divided into multiple logical areas, such as a system partition, a cache partition, and a user data partition. Each partition has independent read / write permission settings and data management based on its functional characteristics. For example, the system partition is mainly used to store critical system files such as the operating system kernel and drivers, ensuring the stable operation of the device; the cache partition focuses on high-speed data caching to improve data access efficiency; and the user data partition provides personalized storage space for users, ensuring the security and privacy of user data.
[0104] Meanwhile, the storage module also features data encryption and security protection. Through a built-in encryption chip and security algorithms, sensitive data stored within it is encrypted to prevent data leakage and unauthorized tampering. In the event of a malicious attack on the vehicle or a system malfunction, the storage module can automatically trigger a security protection mechanism to back up and restore critical data, ensuring the data security and system stability of the dual-view EL display device.
[0105] The addition of this storage module represents a significant leap forward in data storage and management for dual-view EL display devices. It not only enhances the overall performance and user experience of the device but also provides ample room for future functional expansion and intelligent upgrades. Working in conjunction with the controller, the storage module will become a key support for dual-view EL display devices to play a greater role in the smart cockpit field.
[0106] In one embodiment of this invention, to ensure the stability and reliability of the overall structure of the dual-view EL display device, a key component called a bezel is specially added to the device.
[0107] The frame is precisely positioned around the EL display panel 1 and the LENS structure 2, and its design fully considers structural mechanics principles and installation process requirements. Through precise mold forming technology, the frame seamlessly fits the edges of the EL display panel 1 and the LENS structure 2, forming a stable mechanical connection. For fixing, the frame employs a dual fixing mechanism combining clips and screws. On one hand, multiple elastic clips are provided on the inner side of the frame, tightly engaging with corresponding slots on the edges of the EL display panel 1 and the LENS structure 2 to achieve initial positioning and fixation. On the other hand, screw holes are pre-drilled at the four corners and key connection points of the frame, further reinforcing the structure with high-strength screws. This ensures that even during severe vibrations and bumps while the vehicle is in motion, the EL display panel 1 and the LENS structure 2 remain stable and will not loosen or shift.
[0108] In terms of material selection, the frame offers two high-quality options: metal and high-strength plastic. Metal frames, such as aluminum alloy frames, offer advantages such as low density, high strength, and good heat dissipation. Their anodized surface treatment not only gives them a stylish appearance but also significantly improves their corrosion resistance and wear resistance, enabling them to withstand the complex environmental conditions inside vehicles. High-strength plastic frames, such as polycarbonate (PC) frames, are lightweight, low-cost, and highly malleable. Through special injection molding processes and surface treatment technologies, high-strength plastic frames can also achieve high-strength structural support and a good aesthetic effect, meeting the diverse needs of different users for product cost-effectiveness and appearance.
[0109] To further enhance the user experience and operational safety, the bezel surface is meticulously designed with an anti-slip texture. These textures are created using advanced molding techniques, forming a fine and regular concave-convex structure on the bezel surface. When users hold or touch the bezel, the anti-slip texture effectively increases the friction between their fingers and the bezel, preventing slippage caused by sweaty hands or shaking during vehicle operation. Furthermore, the anti-slip texture design incorporates ergonomic principles; its shape and distribution conform to the natural gripping habits of human fingers, making the operation of dual-view EL display devices more comfortable and convenient.
[0110] In addition, the edges of the frame are rounded to prevent sharp corners from causing accidental injury to users. At the installation interface, the frame has pre-drilled slots and connectors that match the vehicle's interior, allowing the dual-view EL display device to be easily and securely installed on the vehicle's dashboard or center console, perfectly blending into the vehicle's interior environment.
[0111] The addition of this bezel provides comprehensive structural protection and functional enhancement for the dual-view EL display device. It not only ensures the stable installation and reliable operation of the EL display panel 1 and the LENS structure 2, but also improves the overall product quality and user experience through the selection of high-quality materials and user-friendly design details.
[0112] In one embodiment of this invention, to ensure the stable operation and efficient power supply of the dual-view EL display device, a key component called a power interface is specially added to the device, serving as a bridge between the external power supply and the internal circuitry.
[0113] The power interface achieves a tight electrical connection with the driver 3 through carefully designed circuit wiring, establishing a safe and stable power transmission channel. The interface design fully considers the complex electromagnetic environment and power supply characteristics inside the vehicle, employing an automotive-grade connector that conforms to international standards, possessing excellent performance such as high reliability, high temperature resistance, and vibration resistance. The connector internally incorporates multiple contact springs to ensure stable electrical contact even under frequent plugging and unplugging and severe vibrations during vehicle operation, preventing voltage fluctuations or power outages due to poor contact.
[0114] In terms of power supply, the power interface plays a crucial role in providing external power to the EL display panel 1. It has a wide input voltage range, adapting to common 12V or 24V power systems in vehicles. Through a built-in power conversion module, it converts the input DC voltage into a stable operating voltage required by the EL display panel 1 and driver 3. The power conversion module employs efficient switching power supply technology, featuring high conversion efficiency and low ripple noise. While providing sufficient power to the equipment, it effectively reduces power loss and heat generation, improving the overall energy efficiency of the device.
[0115] To ensure power supply safety, the power interface is equipped with multiple protection mechanisms. For overvoltage protection, when the input voltage exceeds a set threshold, the protection circuit will quickly cut off the power supply to prevent damage to the EL display panel 1 and driver 3 due to excessive voltage. For overcurrent protection, the output current is monitored in real time, and when the current exceeds the rated value, the current output is automatically limited to avoid safety accidents caused by short circuits or overloads. In addition, it also has reverse connection protection; even if the power polarity is reversed, it will not damage the equipment, effectively improving the device's resistance to misoperation.
[0116] In terms of installation and wiring, the power interface adopts a modular design for easy and quick integration with the vehicle's power system. Its installation location is carefully planned, typically situated on the back or side of the dual-view EL display device, facilitating power cable connection without compromising the overall aesthetics of the device. The power cable uses highly flexible automotive-grade cable, possessing excellent abrasion resistance, high-temperature resistance, and anti-interference capabilities, adapting to the complex wiring environment inside the vehicle and ensuring stable and reliable power transmission.
[0117] The addition of this power interface provides reliable power for the dual-view EL display device. It not only meets the power supply requirements of EL display panel 1 and driver 3, but also ensures the safe and stable operation of the device in various complex environments through multiple protection mechanisms and excellent design details. This innovative design allows the dual-view EL display device to be better integrated into the vehicle's electrical system, providing robust energy support for the display functions of the smart cockpit and driving the development of in-vehicle display technology to a higher level.
[0118] Although this application uses terms such as EL display panel and LENS structure frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
[0119] This utility model provides a dual-view EL display device. By setting a LENS structure with a continuous wave-shaped surface on one side of the EL display panel in the display direction, it can provide dual-view display functionality, thereby effectively solving the limitations of existing vehicle displays in terms of functional design and target audience. This structural design not only meets the driver's need for clear and accurate display of driving-related information, but also provides the front passenger with an independent and high-quality entertainment information display experience. Through the special design of the LENS structure, the display screen can present different content from different viewing angles, realizing dual-view functionality for both the driver and front passenger. This significantly improves the front passenger's in-vehicle entertainment experience while ensuring driving safety, enhancing the overall user experience and comfort of the vehicle.
[0120] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
