Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a dual-view EL display device. Background Art

[0002] As an information output device, the display screen is an important way of interaction between humans and machines. For example, the display screen equipped inside a vehicle is not only a key window for the driver to obtain important information such as vehicle status, navigation information, and driving data, but also an interface for the co-driver to obtain entertainment information such as music playback and video playback during the journey, thus affecting the driving safety and comfort to a certain extent.

[0003] However, in view of the actual application of current vehicle display screens, there are obvious limitations in their functional design and service objects. At present, the display screens on vehicles are mainly laid out and presented in terms of content around the usage needs of the driver. While giving priority to ensuring that the driver can clearly and accurately obtain various types of information required, the usage experience of the co-driver is ignored. When the display screen focuses on presenting driving-related content for the driver, it is often difficult for the co-driver to use the display screen for entertainment activities, which directly results in the co-driver being unable to obtain a good in-vehicle entertainment experience.

[0055] Please refer to Figure 1-2 Figure 1-2 , an embodiment of the present invention 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 placed on the display direction side of the EL display panel 1 and combined with it in a specific spatial position relationship to jointly construct a complete display function system;

[0057] Both opposite surfaces of the LENS structure 2 exhibit a unique geometric shape of continuous waviness, and 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 the embodiment of the present invention realizes the innovative function of dual-view display by carefully arranging the LENS structure 2 with a continuous wavy surface on the display direction side of the EL display panel 1. This technological breakthrough is of great significance for effectively solving the limitations in the functional design and service objects of existing vehicle display screens. Specifically, in the application scenarios of traditional vehicle display screens, it is often difficult to take into account the different usage requirements of the driver and the co-driver, resulting in a large limitation on the entertainment experience of the co-driver during the ride. However, in the dual-view EL display device designed in the present invention, the special design of the LENS structure 2 enables the display screen to present completely different contents at different viewing angles.

[0059] For the driver, the device can accurately meet his clear and accurate display requirements for driving-related information. During driving, the driver can obtain key driving data such as the vehicle driving status, navigation information, and road condition prompts through a specific viewing angle, thereby ensuring the safety and accuracy of driving operations. For the co-driver, the device can provide an independent and high-quality entertainment information display experience. The co-driver does not need to share the same display screen with the driver, but can adjust the viewing angle to enjoy a variety of entertainment contents such as music playback, video streaming, and gaming, greatly enriching the leisure time during the ride.

[0060] Through the special optical design of the LENS structure 2, the display screen realizes the dual-view function for the driver and the co-driver. This innovative design not only plays an important role in ensuring driving safety, enabling the driver to focus on driving information and reducing distractions caused by operating the display screen; at the same time, it also significantly improves the co-driver's in-vehicle entertainment experience and enhances the overall user experience and comfort of the vehicle. In the long run, the popularization and application of this technology are expected to promote the further development of vehicle display screen technology and bring more intelligent and user-friendly display solutions to the automotive industry.

[0061] Please refer to again Figure 2 ,In an implementation manner of this embodiment, both opposite surfaces of the LENS structure 2 exhibit a unique continuous wavy shape formed by a number of closely connected arcs. Specifically, the endpoints of each arc are precisely connected to the endpoints of the adjacent arcs. This design not only ensures the continuity and smoothness of the surface of the LENS structure 2, but also endows it with unique optical characteristics and functional advantages.

[0062] In terms of optical performance, the continuous wavy surface formed by the connection of the arc endpoints enables complex refraction and reflection phenomena to occur when light passes through the LENS structure 2. This optical effect not only enhances the focusing ability of light, improves the clarity and brightness of the display screen, but also provides a key optical basis for realizing the dual-view display function. By precisely controlling the radius, curvature of the arcs, and the connection angle between adjacent arcs, the optical performance of the LENS structure 2 can be further optimized, so that it presents different display effects at different viewing angles.

[0063] In terms of function realization, this special design of the LENS structure 2 enables the dual-view EL display device to present clear and independent display contents at two different viewing angles of the driver's seat and the passenger seat. For the driver, the display screen in his view mainly focuses on driving-related information, such as vehicle speed, navigation prompts, road condition warnings, etc., to ensure the safety and accuracy of driving operations. For the co-driver, by adjusting the viewing angle, he can enjoy entertainment contents that are completely different from the driver's view, such as music playback, video streaming media, game entertainment, etc., thus greatly enriching the leisure experience during the ride.

[0064] In addition, the continuous wavy design of the LENS structure 2 also has certain structural stability and durability. The connection method of the arc endpoints enables 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 a complex and changeable driving environment.

[0065] In summary, the opposite surfaces of the LENS structure 2 adopt a continuous wavy design formed by a number of connected arcs, which not only realizes the dual-view display function, but also optimizes the optical performance, enhances the structural stability and durability.

[0066] Please refer to Figure 3 ,In an implementation manner of this embodiment, the dual-view EL display device further adds a key component, the driver 3;

[0067] A professional electrical connection method is used to achieve a tight coupling between the driver 3 and the EL display panel 1. This electrical connection is not a simple physical contact, but is based on a specific circuit design and signal transmission protocol, aiming to ensure that the driver 3 can efficiently and stably transmit various control signals and power supplies to the EL display panel 1.

[0068] As the core control unit of the dual-view EL display device, the driver 3 plays a crucial role. It can not only precisely regulate key display parameters such as the display 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 requirements of the actual application scenario, such as the single-view display mode, dual-view display mode, etc.

[0069] In the dual-view display mode, through complex signal processing algorithms and precise timing control, the driver 3 can ensure that the EL display panel 1 presents clear, independent, and non-interfering display contents from two different perspectives of the driver's and passenger's seats. Specifically, the driver 3 will perform real-time segmentation and processing on the input video signal according to the preset perspective parameters and display contents, generate two different display data streams, and transmit them to the corresponding display areas of the EL display panel 1 respectively. At the same time, the driver 3 will also perform necessary preprocessing and correction on the display data stream according to the optical characteristics of the LENS structure 2 to ensure accurate and clear display effects from different perspectives.

[0070] In addition, the driver 3 also has strong compatibility and expandability. It can be seamlessly docked with various different types of signal sources, such as in-vehicle entertainment systems, navigation systems, intelligent driving assistance systems, etc., so as to achieve integrated display and interactive control of various information. At the same time, with the continuous development and upgrade of technology, the driver 3 can also introduce new functional features and optimized algorithms through software upgrades or hardware expansions to meet the increasingly diverse application requirements.

[0071] In summary, the addition of the driver 3 provides strong power support and intelligent control capabilities for the dual-view EL display device, significantly improving the display performance, functional features, and user experience of the device.

[0072] Please refer to Figure 4 In an implementation manner of this embodiment, the dual-view EL display device is further optimized and configured, and a key interactive component, the touchpad 4, is added;

[0073] The touchpad 4 is carefully arranged 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 combined through specific installation processes and structural fixing methods, ensuring both the stability and reliability of the touchpad 4 and that the optical synergy between it and the LENS structure 2 is not affected.

[0074] As an important interaction interface of the dual-view EL display device, the touchpad 4 undertakes the key tasks of information transmission and command input between the user and the device. It adopts advanced touch control technology and highly sensitive sensors, which can capture the user's touch actions and gesture operations in real time and accurately, and convert them into corresponding electrical signals for transmission to the driver 3 for processing.

[0075] In the dual-view display mode, the addition of the touchpad 4 provides a more intuitive and convenient operation experience for users. The driver and the co-driver can perform independent interaction operations through the touchpad 4 according to the display content in their respective perspectives. For example, the driver can quickly switch the navigation interface, adjust driving parameters, or answer calls through the touchpad 4; while the co-driver can browse entertainment programs, control music playback, or perform game operations through the touchpad 4. This design of partitioned touch control not only avoids operation interference between the driver and the co-driver, but also improves the efficiency and accuracy of interaction operations.

[0076] In addition, the touchpad 4 also has a high degree of customization and expandability. According to different actual application scenarios and user requirements, the touch control area, touch sensitivity, gesture recognition algorithm, etc. of the touchpad 4 can be customized and optimized. At the same time, with the continuous development and upgrading of technology, the touchpad 4 can also be combined with other interaction technologies such as voice recognition and gesture recognition to form a more diversified and intelligent interaction system.

[0077] In summary, the addition of the touchpad 4 adds powerful interaction capabilities to the dual-view EL display device, significantly improving the device in terms of user experience, operation convenience, and function expandability. This innovative design not only meets the user's needs for an intelligent and convenient interaction experience, but also opens up a new direction for the development of vehicle display screen technology.

[0078] Please refer to Figure 5 , in an implementation manner of this embodiment, the dual-view EL display device further optimizes the protection system and adds a key protection component, the 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 all-round and multi-level protection for the touchpad 4. The protective film 5 and the touchpad 4 are tightly combined through specific bonding processes and material selections, ensuring both the flatness and transparency of the protective film 5 and the touch sensitivity between it and the touchpad 4 without being affected.

[0080] As an important protective barrier of the dual-view EL display device, the protective film 5 undertakes the key task of resisting external physical damage, chemical corrosion, and environmental factor erosion. It is made of high-strength and high-toughness materials and has excellent scratch resistance, impact resistance, wear resistance, etc. At the same time, the protective film 5 also has special functions such as fingerprint resistance and anti-glare, which can effectively reduce the stain residue and light reflection on the surface of the touchpad 4 and improve the visual comfort of users under various lighting conditions.

[0081] In the 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 quick touch operations during driving or the co-driver conducts long-term touch interactions during leisure and entertainment, the protective film 5 can effectively resist various accidental damages and wear, ensuring the long-term stable operation and touch accuracy of the touchpad 4.

[0082] In addition, the protective film 5 also has the characteristics of being 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 beauty through simple cleaning operations; when the protective film 5 shows aging or damage due to long-term use, users can also 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 adds powerful protection capabilities to the dual-view EL display device, significantly improving the device in terms of durability, reliability, and user experience. This innovative design not only extends the service life of the touchpad 4 but also reduces the maintenance cost and usage risk for users.

[0084] Please refer to Figure 6 , in an implementation manner of this embodiment, the protective film 5 adopts an innovative multi-layer composite structure design, which aims to comprehensively improve the comprehensive performance of the protective film 5 and provide a more excellent protection effect for the dual-view EL display device.

[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. Among them, 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 mechanical properties such as tensile resistance and bending resistance, providing a stable attachment platform for the functional layer 502.

[0086] The functional layer 502 is carefully disposed on the base layer 501. Through specific process and material selection, the integration and optimization of multiple functions are achieved. The functional layer 502 successively includes a blue light blocking coating 5021, an anti-reflection layer 5022, and an oleophobic layer 5023 from bottom to top. Each layer undertakes specific functional tasks and jointly constitutes the multi-functional protection system of the protective film 5.

[0087] The blue light blocking coating 5021 is located at the bottommost layer of the functional layer 502 and is disposed closely against the base layer 501. This coating adopts advanced blue light filtering technology, which can effectively absorb and reflect light in the blue light band, reduce the harm of blue light to the eyes, and provide a healthier and more comfortable visual experience for users. Especially when using the dual-view EL display device for a long time, the blue light blocking coating 5021 can significantly reduce the irritation of blue light to the eyes and protect the visual health of users.

[0088] The anti-reflection layer 5022 is located above the blue light blocking coating 5021. It adopts special anti-reflection materials and processes, which can effectively reduce the reflection and scattering of external light on the surface of the protective film 5, and improve 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 highly oleophobic materials, which can effectively prevent the attachment and residue of contaminants such as fingerprints and oil stains on the surface of the protective film 5, and keep the protective film 5 clean and beautiful. At the same time, the oleophobic layer 5023 also has excellent self-cleaning performance, which can reduce the problem of unresponsive touch caused by hand oils and stains, and ensure the smoothness and accuracy of the user's touch operation.

[0090] Through the design of the protective film 5 with such a multi-layer composite structure, while providing the dual-view display function, the dual-view EL display device can further guarantee the user experience and health and safety. The protective film 5 not only provides physical protection for the touchpad 4, but also optimizes the use performance of the dual-view EL display device in different environments through its special design of the functional layer 502, significantly improving the overall user experience and comfort of the vehicle.

[0091] In an implementation manner of this embodiment, the dual-view EL display device further integrates an integrated controller, which serves as the core control hub of the device to achieve efficient collaborative management of the display logic and drive signals.

[0092] The controller constructs a bidirectional communication link with the EL display panel 1 and the driver 3 through a precise electrical connection architecture. Its hardware interface adopts high-speed serial bus protocols (such as MIPI DSI, eDP, etc.) to ensure real-time and stable transmission of display data and control instructions. At the software level, the controller has a dual-core processor architecture. The main core is responsible for running the display control algorithm based on RTOS (Real-Time Operating System), and the secondary core focuses on the 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 with the optical parameters of the LENS structure 2, it realizes the dynamic content separation of the main and co-pilot perspectives. The spatial light modulation (SLM) algorithm is used to encode the perspective of the original image, generating two independent sub-frame data streams, which respectively correspond to the driving information interface of the driver and the entertainment content interface of the co-pilot.

[0095] (2) Adaptive brightness adjustment system: Integrates an ambient light sensor and a vehicle status monitoring module to obtain parameters such as the external light intensity, vehicle speed, and battery power in real time. Based on the fuzzy PID control algorithm, it dynamically adjusts the light emission intensity of the EL display panel 1 and the supply voltage of the driver 3, achieving more than 20% energy consumption optimization while ensuring display clarity.

[0096] (3) Intelligent touch collaboration module: Establishes low-latency communication with the touchpad 4 through the I2C bus and uses machine learning algorithms to parse the touch trajectory in real time. When multi-finger gestures are detected, it automatically triggers the dual-screen interaction mode. For example, in the navigation scenario, it allows the co-pilot to mark points of interest through the touchpad 4, and synchronously displays the route planning suggestions on the driver's screen.

[0097] In terms of safety redundancy design, the controller adopts a dual-channel power supply 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. At the same time, its firmware supports the OTA (Over-the-Air) upgrade function, and can receive algorithm update packages pushed from the cloud through the in-vehicle T-BOX module to continuously optimize the display effect and interaction experience.

[0098] The introduction of this controller enables the dual-view EL display device to break through the functional boundaries of traditional in-vehicle display screens and realizes the intelligent leap from passive display to active interaction. Through the collaborative design of software and hardware, it not only meets the core requirements of the intelligent cockpit 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 implementation of this embodiment, to further enhance the functionality and intelligence level 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 is tightly electrically connected to the controller through a high-speed data bus to establish an efficient data interaction channel. This connection method not only ensures the stability and real-time nature of data transmission but also provides a solid hardware foundation for subsequent complex data processing and operations. 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 anti-seismic and anti-impact capabilities, and can perfectly adapt to the strict requirements of the vehicle environment for device reliability.

[0101] In terms of function implementation, the storage module undertakes multi-dimensional storage tasks for the display content of the EL display panel 1. On the one hand, as a local cache, it can temporarily store the image data to be displayed, video streams, and various interaction instructions received from the controller. During vehicle driving, when the network connection is unstable or there are short data transmission delays, the storage module can quickly respond and retrieve data from the cache to ensure that there are no phenomena such as freezing or screen distortion in the display content of the EL display panel 1, providing users with a smooth and stable visual experience.

[0102] On the other hand, the storage module also has a long-term data storage function. It can save user-defined display settings, such as brightness adjustment parameters, color mode preferences, dual-view display mode switching habits, etc. When the user starts the vehicle again, the controller can automatically read these personalized settings from the storage module and quickly apply them to the EL display panel 1 to achieve the convenient operation of "turn on and use immediately". In addition, for some important driving information, navigation records, and multimedia content, the storage module can also perform secure storage for users to view and playback at any time.

[0103] To meet the data storage requirements in different application scenarios, the storage module adopts a flexible partition management strategy. The storage space is divided into multiple logical areas such as a system partition, a cache partition, and a user data partition, and each partition is independently set with read and write permissions and data management according to its functional characteristics. For example, the system partition is mainly used to store key system files such as the operating system kernel and driver programs to ensure the stable operation of the device; the cache partition focuses on high-speed data caching to improve data access efficiency; the user data partition provides users with personalized storage space to ensure the security and privacy of user data.

[0104] Meanwhile, the storage module also has data encryption and security protection functions. Through the built-in encryption chip and security algorithm, the sensitive data stored therein is encrypted to prevent data leakage and illegal tampering. When the vehicle is under malicious attack or the system has anomalies, the storage module can automatically trigger the 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 has brought a qualitative leap to the dual-view EL display device in terms of data storage and management. It not only improves the overall performance and user experience of the device but also provides broad space for subsequent function expansion and intelligent upgrade. By working in coordination with the controller, the storage module will become the key support for the dual-view EL display device to play a greater role in the intelligent cockpit field.

[0106] In one implementation of this embodiment, to ensure the stability and reliability of the overall structure of the dual-view EL display device, a crucial component, the frame, is specially added to the device.

[0107] The frame is precisely set around the EL display panel 1 and the LENS structure 2. Its design fully considers the principles of structural mechanics and the requirements of installation technology. Through precise mold forming technology, the frame is seamlessly fitted with the edges of the EL display panel 1 and the LENS structure 2, forming a stable mechanical connection. In terms of the fixing method, the frame adopts a dual fixing mechanism combining snap and screw fastening. On the one hand, multiple elastic snaps are set on the inner side of the frame, which closely cooperate with the corresponding slots on the edges of the EL display panel 1 and the LENS structure 2 to achieve preliminary positioning and fixing. On the other hand, screw holes are reserved at the four corners and key connection parts of the frame, and high-strength screws are used for further reinforcement to ensure that during the vehicle's driving process, even in the face of severe vibrations and bumps, the EL display panel 1 and the LENS structure 2 can remain stable without loosening or displacement.

[0108] In terms of material selection, the frame offers two high-quality options: metal and high-strength plastic. The metal frame, such as an aluminum alloy frame, has the advantages of low density, high strength, and good heat dissipation performance. Its surface is treated by anodic oxidation, which not only gives the frame a fashionable appearance texture but also significantly improves its corrosion resistance and wear resistance, enabling it to adapt to the complex environmental conditions inside the vehicle. The high-strength plastic frame, such as a polycarbonate (PC) frame, has the characteristics of light weight, low cost, and strong plasticity. Through special injection molding technology and surface treatment technology, the high-strength plastic frame can also achieve high-strength structural support and good appearance effects, meeting the diverse needs of different users for product cost performance and appearance styles.

[0109] To further enhance the user experience and operation safety, anti-slip textures are carefully set on the surface of the border. These anti-slip textures adopt advanced die engraving technology, forming a fine and regular concave-convex structure on the border surface. When the user holds or touches the border, the anti-slip textures can effectively increase the friction between the fingers and the border, preventing the hand-slip phenomenon caused by sweating or the shaking during vehicle driving. At the same time, the design of the anti-slip textures also takes into account the principles of ergonomics, and its shape and distribution conform to the natural grasping habits of human fingers, making it more comfortable and convenient for users to operate the dual-view EL display device.

[0110] In addition, the edge part of the border is rounded to avoid accidental injuries to users caused by sharp corners. At the installation interface, the border is reserved with slots and connectors that match the vehicle interior, enabling the dual-view EL display device to be easily and firmly installed on the vehicle instrument panel or console, and perfectly integrated with the vehicle interior environment.

[0111] The addition of this border provides comprehensive structural protection and function 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 quality and user experience of the product through high-quality material selection and user-friendly design details.

[0112] In one implementation of this embodiment, to ensure the stable operation and efficient power supply of the dual-view EL display device, a key component, the power interface, is specially added as a bridge between the external power supply and the internal circuit.

[0113] The power interface is closely electrically connected to the driver 3 through carefully designed circuit traces, building a safe and stable power transmission channel. In the interface design, the complex electromagnetic environment and power supply characteristics inside the vehicle are fully considered, and an automotive-grade connector that meets international standards is adopted, which has excellent performance such as high reliability, high temperature resistance, and anti-vibration. Multiple contact spring pieces are set inside the connector to ensure stable electrical contact under frequent plugging and unplugging and severe vibrations during vehicle driving, avoiding voltage fluctuations or power outages caused by poor contact.

[0114] In terms of the power supply function, the power interface undertakes the important task of providing external power for the EL display panel 1. Its input voltage range is wide, and it can adapt to the common 12V or 24V power supply systems in vehicles. Through the built-in power conversion module, the input DC voltage is converted into the stable working voltages required by the EL display panel 1 and the driver 3. The power conversion module adopts efficient switching power supply technology, which has characteristics such as high conversion efficiency and low ripple noise. While providing sufficient electrical energy for the device, it effectively reduces power loss and heat generation, and improves the energy utilization efficiency of the entire device.

[0115] To ensure power supply safety, the power interface is equipped with multiple protection mechanisms. In terms of overvoltage protection, when the input voltage exceeds the set threshold, the protection circuit will quickly cut off the power supply to prevent damage to the EL display panel 1 and the driver 3 caused by excessive voltage; in terms of overcurrent protection, the output current is monitored in real time. 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 function. Even if the power supply polarity is reversed, it will not cause damage to the device, effectively improving the anti-misoperation ability of the device.

[0116] In terms of installation and wiring, the power interface adopts a modular design, which is convenient for quick docking with the vehicle power system. Its installation position is carefully planned and is usually set on the back or side of the dual-view EL display device, which is convenient for connecting the power cord and does not affect the overall aesthetics of the device. The power cord uses a highly flexible automotive special cable, which has good abrasion resistance, high temperature resistance and anti-interference ability, can adapt to the complex wiring environment inside the vehicle, and ensure the stability and reliability of power transmission.

[0117] The addition of this power interface provides reliable power guarantee for the dual-view EL display device. It not only meets the power supply requirements of the EL display panel 1 and the driver 3, but also ensures the safe and stable operation of the device in various complex environments through multiple protection mechanisms and high-quality design details. This innovative design enables the dual-view EL display device to better integrate into the vehicle electrical system, provides solid energy support for the display function of the intelligent cockpit, and promotes the development of in-vehicle display technology to a higher level.

[0118] Although terms such as EL display panel and LENS structure are used more frequently in this application, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0119] A dual-view EL display device provided by an embodiment of the present invention can provide a dual-view display function by setting a LENS structure with a continuous wavy surface on the display direction side of the EL display panel, thereby effectively solving the limitations of existing vehicle display screens in terms of function design and service objects. That is, this structural design can not only meet the clear and accurate display requirements of drivers for driving-related information, but also provide an independent and high-quality entertainment information display experience for the co-driver at the same time. Through the special design of the LENS structure, the display screen can present different contents at different viewing angles, realizing the dual-view function of the driver and co-driver, thereby while ensuring driving safety, significantly improving the co-driver's in-vehicle entertainment experience and enhancing the overall user experience and comfort of the vehicle.
