Abstract
Description
Technical Field
[0001] This utility model relates to the field of display technology, and in particular to a novel dual-view display screen and vehicle. Background Technology

[0010] The privacy film is applied to the dual-view display panel;
[0011] The privacy film has a visible angle of 20°-90° from both the left and right sides, and a non-visible angle of less than 20°.
[0012] The privacy film is used to display the content of the dual-view display panel normally within the viewing angle, and to block the content of the dual-view display panel from the non-viewing angle to present a blackening effect.

[0027] Furthermore, in the novel dual-view display screen, the optical adhesive layer is an OCA adhesive layer.
[0028] Furthermore, the novel dual-view display also includes an ambient light sensor;
[0029] The ambient light sensor is electrically connected to the backlight and is used to detect the ambient light intensity, thereby automatically adjusting the brightness of the backlight.
[0030] Furthermore, the novel dual-view display also includes a protective film;

[0038] This invention provides a novel dual-view display screen and vehicle. By incorporating a privacy film on the dual-view display panel, it cleverly solves the problem of existing dual-view displays displaying content from one perspective when viewed from an angle of less than 20°. The privacy film allows the dual-view display panel to display content normally within a viewing angle of 20°-90°, ensuring that users at both viewing angles can clearly see their respective information. At non-viewing angles within 20°, the film obscures the display content, creating a blacked-out effect and effectively preventing incorrect information display. This innovative design significantly improves the privacy protection performance of the dual-view display screen while optimizing the user's viewing experience and avoiding the risk of information interference and leakage due to viewing angle issues.

[0065] Example 1
[0066] In view of the deficiencies in the existing technology, the applicant, based on years of practical experience and professional knowledge in this field, and in conjunction with theoretical application, has actively conducted research and innovation in order to create a technology that can solve the deficiencies in the existing technology. After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.
[0067] Please refer to Figure 1-2 This utility model provides a novel dual-view display screen, including a dual-view display panel 100 and a privacy film 200;
[0068] The dual-view display panel 100, as the core carrier of information display, possesses a unique multi-view display function. Specifically, it can independently and accurately present different display content from two distinctly different viewing angles. This feature enables the dual-view display panel 100 to fully meet the personalized information acquisition needs of diverse user groups in multi-view scenarios. For example, in a vehicle's in-vehicle information display system, it can provide drivers and passengers with their own exclusive driving information and entertainment content; in financial transaction terminal equipment, it can simultaneously display different transaction information and prompts to operators and customers.
[0069] The privacy screen protector 200, a key component ensuring the security and privacy of displayed information, is cleverly positioned on the dual-view display panel 100. This privacy screen protector 200 is meticulously designed and optimized, possessing specific viewing angle control characteristics. In the two different viewing directions (left and right), its visible angle range is strictly limited to 20°-90°, while the corresponding non-visible angle range is within 20°.
[0070] The privacy film 200 plays a crucial role in practical applications. When the user's viewing angle is within the 20°-90° viewing angle range, the privacy film 200 ensures that all content displayed on the dual-view display panel 100 is presented to the user with a normal and clear visual effect. This feature guarantees that users with different viewing angles on the left and right can accurately obtain the corresponding display information within their respective effective viewing areas, thereby achieving efficient and convenient information interaction.
[0071] However, when the user's viewing angle is within 20° of the non-visual angle range, the privacy film 200 will obscure the content displayed on the dual-view display panel 100, giving it a distinct blackened effect. This unique design effectively prevents information from being displayed incorrectly at unexpected viewing angles, fundamentally eliminating the risk of information errors and leaks caused by viewing angle issues, and providing a solid guarantee for the user experience and privacy.
[0072] This invention, through the innovative placement of a privacy film 200 on the dual-view display panel 100, successfully overcomes the problem of information interference and leakage in existing dual-view displays when viewed at angles within 20°. Within a viewing angle range of 20°-90°, the privacy film 200 ensures that the content of the dual-view display panel 100 is presented with optimal visual effect, allowing users from both left and right viewing angles to obtain clear and accurate visual information. Within a non-viewing angle range of 20°, the blackout masking function effectively prevents incorrect display and leakage of information. This innovative design not only significantly improves the privacy protection performance of the dual-view display but also greatly optimizes the user's viewing experience, laying a solid foundation for the application and development of dual-view display technology in a wider range of fields.
[0073] Please refer to Figure 3 In one embodiment of this invention, the dual-view display panel 100 employs a meticulously designed multi-layer composite structure, whose detailed components include a backlight 1, a lower polarizer 2, a TFT panel 3, an optical adhesive layer 4, a lens structure 5, an upper polarizer 6, and a glass cover 7. The arrangement, connection method, and structural characteristics of each component will be described in detail below.
[0074] Regarding the arrangement of components, the backlight 1, lower polarizer 2, TFT panel 3, LENS structure 5, upper polarizer 6, and glass cover 7 are stacked tightly from bottom to top, forming a highly integrated display module. This layered stacking structure not only ensures close cooperation and collaborative work between the components, but also provides stable physical support and optical foundation for the dual-view display panel 100.
[0075] Regarding the connection method of the components, an optical adhesive layer 4 is provided between the TFT panel 3 and the LENS structure 5. This optical adhesive layer 4 is uniformly filled between the two through a precise coating process, achieving a strong bond and seamless connection between them. Similarly, another optical adhesive layer 4 is also provided between the upper polarizer 6 and the glass cover plate 7, further enhancing the overall structural strength and stability of the display module. These two optical adhesive layers 4 not only serve an adhesive function but also have good optical transmittance performance, ensuring smooth light transmission between the components.
[0076] In terms of structural characteristics, the LENS structure 5, as a key optical element in the dual-view display panel 100, has two opposing surfaces designed as continuous waves. This unique wave-shaped surface structure is achieved through a precise mold-forming process, resulting in accurate geometric shape and dimensional control. The wave-shaped surface of the LENS structure 5 can effectively refract and reflect light, thereby enabling clear imaging of the dual-view display panel 100 from different viewing angles. Specifically, when light is emitted from the backlight 1 and passes sequentially through the lower polarizer 2 and the TFT panel 3, it reaches the wave-shaped surface of the LENS structure 5. The light undergoes specific refraction and reflection phenomena according to the surface geometry, allowing users at the left and right viewing angles to receive optimized light signals respectively, thus seeing clear and independent display content within their respective viewing ranges.
[0077] The dual-view display panel 100 provided in this embodiment achieves clear and independent display functions from two different viewing angles by adopting the aforementioned carefully designed multi-layer composite structure and combining it with the unique wave-shaped surface design of the LENS structure 5. This innovative design not only improves the display performance and user experience of the dual-view display panel 100, but also provides strong technical support for the application and development of dual-view display technology in a wider range of fields.
[0078] Please refer to Figure 4 In another embodiment of this invention, the dual-view display panel 100 may also employ a different multi-layer composite structure, the core components of which include a backlight 1, a lower polarizer 2, a TFT panel 3, an optical adhesive layer 4, a lens structure 5, an upper polarizer 6, and a glass cover 7. The following will provide a detailed and in-depth description of the arrangement, connection method, and structural characteristics of each component in this embodiment.
[0079] In terms of component arrangement, the backlight 1, lower polarizer 2, TFT panel 3, upper polarizer 6, and glass cover 7 are stacked tightly in sequence from bottom to top, forming a highly integrated and stable display module. This layered stacking design not only ensures close cooperation and efficient operation between components, but also provides solid physical support and excellent optical foundation for the dual-view display panel 100, ensuring stable and clear display effects.
[0080] Regarding the connection method of the components, the TFT panel 3 features an ingenious structural design, comprising two TFT glass substrates 31. These two TFT glass substrates 31 are precisely stacked in a parallel manner and tightly bonded through advanced encapsulation technology. The LENS structure 5 is cleverly encapsulated between the two TFT glass substrates 31. This encapsulation method not only enhances the stability and reliability of the LENS structure 5 but also optimizes the light transmission path within the panel. Simultaneously, an optical adhesive layer 4 is disposed between the TFT glass substrate 31 and the upper polarizer 6, and another optical adhesive layer 4 is disposed between the upper polarizer 6 and the glass cover plate 7. These two optical adhesive layers 4, with their excellent adhesion and optical transmittance, ensure a firm connection between the components and smooth light transmission, further enhancing the overall performance of the display module.
[0081] In terms of structural characteristics, the LENS structure 5, as a key optical element in the dual-view display panel 100, has its two opposing surfaces meticulously designed as continuous waves. This unique wave-shaped surface structure is manufactured through a high-precision mold forming process, achieving precise geometric shape and dimensional control. The wave-shaped surface of the LENS structure 5 can perform complex and precise refraction and reflection of light, thereby achieving excellent imaging effects of the dual-view display panel 100 at different viewing angles. Specifically, when light is emitted from the backlight 1 and passes sequentially through the lower polarizer 2 and the TFT panel 3, it reaches the wave-shaped surface of the LENS structure 5. The light undergoes specific refraction and reflection phenomena according to the surface geometry. The light processed by the LENS structure 5 forms clear and independent images at two different viewing angles, allowing users at the left and right viewing angles to receive optimized light signals respectively, thus seeing clear and accurate display content within their respective viewing ranges.
[0082] Furthermore, the parallel stacking of the two TFT glass substrates 31 provides the TFT panel 3 with greater design space and higher performance potential. By rationally arranging circuits and components between the two TFT glass substrates 31, precise control and efficient driving of the display pixels can be achieved, further improving key performance indicators such as display resolution, color reproduction, and response speed of the dual-view display panel 100.
[0083] The dual-view display panel 100 provided in this embodiment achieves clear and independent display functions from two different viewing angles by adopting the above-mentioned innovative multi-layer composite structure, combined with the unique wave-shaped surface design of the LENS structure 5 and the double-layer glass substrate structure of the TFT panel 3.
[0084] In one embodiment of this invention, the two opposing surfaces of the LENS structure 5 exhibit a highly complex and sophisticated optical design feature, namely, a continuous wave-like structure composed of several closely connected arcs. This wave-like structure is not a simple undulating shape, but rather a result of precise calculation and optimized design to ensure that light can achieve accurate refraction and reflection when passing through the LENS structure 5, thereby achieving an ideal dual-view display effect.
[0085] Specifically, the endpoints of each arc seamlessly connect with the endpoints of adjacent arcs, forming a continuous, smooth, and highly regular surface profile. This design allows the surface of the LENS structure 5 to exhibit a periodic change similar to a sine or cosine wave at the microscopic level, but at the macroscopic level, it appears as a smoothly transitioning wave-like surface. This unique surface morphology not only provides a rich selection of paths for light propagation but also enables independent control of light from two different perspectives by precisely controlling the refraction angle and reflection direction.
[0086] During light propagation, as light is emitted from the backlight and passes sequentially through the lower polarizer and the TFT panel, reaching the wavy surface of the LENS structure 5, the curved shape of each arc produces a specific refraction effect on the light. Because the curvature radius of the arcs and the transition between adjacent arcs are carefully designed, the light undergoes a slight deflection as it passes through each arc. These subtle deflections accumulate, allowing the light to form clear and independent images from two different viewing angles. Simultaneously, the continuous design of the wavy surface ensures the stability and uniformity of light propagation, avoiding optical defects such as light spots and dark lines caused by surface discontinuities.
[0087] Furthermore, this continuous wave-shaped structure, composed of several interconnected arcs, possesses excellent mechanical properties and thermal stability. The smooth transitions between the arcs reduce stress concentration, improving the impact resistance and durability of the LENS structure 5. Simultaneously, the wave-shaped design also helps improve the thermal conductivity of the LENS structure 5, enabling it to maintain stable optical performance even at high temperatures.
[0088] The LENS structure 5 design used in this embodiment achieves precise control and efficient utilization of light by cleverly utilizing the continuity of arcs and the regularity of wave-shaped structures.
[0089] In one embodiment of this example, the optical adhesive layer 4 is an OCA adhesive layer.
[0090] It should be noted that OCA adhesive, as a high-performance optically transparent adhesive, plays a crucial role in the dual-view display panel 100.
[0091] The OCA adhesive layer possesses exceptional optical transparency and extremely high light transmittance, ensuring smooth light transmission between the components of the dual-view display panel 100 with virtually no light loss or optical distortion. This characteristic is crucial for the display performance of the dual-view display panel 100, as it guarantees that users at both the left and right viewing angles can receive clear, accurate, and vibrant image information.
[0092] Please refer to Figure 5-6 In another embodiment of this invention, the novel dual-view display screen further expands its functions based on the original structure by adding an ambient light sensor 8 as a key component.
[0093] The ambient light sensor 8 plays a crucial role in the circuit system of the dual-view display, establishing a stable electrical connection with the backlight 1. This electrical connection is not a simple physical contact, but is achieved through a carefully designed circuit layout and reliable connection technology, ensuring the accuracy and stability of signal transmission between the two.
[0094] The core function of the ambient light sensor 8 is to accurately detect ambient light intensity. It employs advanced photoelectric conversion technology and a highly sensitive photosensitive element, enabling it to sense changes in ambient light in real time and convert these changes into electrical signals for transmission. During the operation of the dual-view display, the ambient light sensor 8 continuously monitors the ambient light intensity, accurately capturing subtle differences in light intensity in both bright outdoor environments and dimly lit indoor spaces.
[0095] Based on the ambient light intensity information detected by the ambient light sensor 8, the control system of the dual-view display can automatically adjust the brightness of the backlight 1. This automatic adjustment mechanism is achieved through advanced control algorithms and precise drive circuits. When the ambient light intensity is high, the control system will correspondingly reduce the brightness of the backlight 1 to avoid the screen being too bright and causing eye strain to the user, while also effectively reducing energy consumption and extending the lifespan of the dual-view display. Conversely, when the ambient light intensity is low, the control system will automatically increase the brightness of the backlight 1 to ensure that the screen content remains clearly visible in dim environments, providing the user with a comfortable visual experience.
[0096] The addition of ambient light sensor 8 enables the new dual-view display to have intelligent brightness adjustment capabilities. This feature not only enhances the adaptability and practicality of the dual-view display, allowing it to automatically adjust the display effect according to different usage environments, but also...
[0097] Please refer to Figure 7-8 In another embodiment of this invention, the novel dual-view display screen is further optimized based on the original structure, and a protective film 9 is added as an important component.
[0098] The protective film 9 occupies a crucial position in the overall structure of the dual-view display screen, precisely covering the outer surface of the glass cover plate 7. This covering method is not a simple physical adhesion, but rather employs advanced bonding technology and precise positioning techniques to ensure a seamless fit between the protective film 9 and the glass cover plate 7, free of bubbles and wrinkles, providing all-round, comprehensive protection for the glass cover plate 7. The presence of the protective film 9 effectively prevents the glass cover plate 7 from being damaged by scratches, collisions, and other external forces during daily use, thereby extending the lifespan of the dual-view display screen and ensuring the stability of its display performance.
[0099] Please refer to Figure 9 In another embodiment of this invention, the protective film 9 of the novel dual-view display screen undergoes further structural optimization and functional expansion. The protective film 9 is designed as a multi-layer composite structure. This structural design fully considers the synergistic effect and performance complementarity between different functional layers, aiming to provide users with a better and more comprehensive user experience.
[0100] Specifically, the multi-layered composite structure of the protective film 9 includes a base layer 91 and a functional layer 92. The base layer 91, as the fundamental support layer of the protective film 9, possesses excellent mechanical properties and stability, providing solid structural support for the entire protective film 9. Based on the base layer 91, the functional layer 92 is carefully designed to further enhance the functionality and practicality of the protective film 9.
[0101] The functional layers 92 are arranged in a bottom-up layered manner, with each layer cooperating and working together to achieve excellent performance. The bottom layer is a blue light blocking coating 921. In today's digital age, people spend long hours in front of electronic displays, and the harmful effects of blue light on the eyes are receiving increasing attention. The blue light blocking coating 921 uses advanced blue light blocking technology to effectively filter out harmful blue light emitted from the display screen, reducing the stimulation and damage to the eyes, thereby protecting the user's visual health.
[0102] An anti-reflective layer 922 is applied over the anti-blue light coating 921. The anti-reflective layer 922 possesses excellent optical properties, reducing the reflectivity of the glass cover 7 surface and minimizing interference from external light reflections on the screen surface. This design not only improves the visibility of the dual-view display under different ambient lighting conditions but also makes the screen content clearer and more vibrant, providing users with a more comfortable visual experience.
[0103] The top layer is an oleophobic layer 923. Oleophobic layer 923 uses special oleophobic materials and processing techniques, giving the protective film 9 surface excellent oleophobic properties. During daily use, fingerprints, oil stains, and other contaminants are difficult to leave on the surface of the protective film 9, and even small amounts of dirt can be easily wiped clean. This design not only maintains the cleanliness and aesthetics of the dual-view display but also improves user convenience.
[0104] In summary, the novel dual-view display screen provided in this embodiment, by adding a protective film 9 and designing it with a multi-layer composite structure, not only provides all-round protection for the glass cover 7, but also endows the protective film 9 with a variety of practical functions such as anti-blue light, anti-reflection, and oleophobicity.
[0105] In another innovative implementation presented in this embodiment, the backlight 1 innovatively adopts zone dimming technology, which brings significant advantages to the performance improvement and functional expansion of the dual-view display.
[0106] Local dimming technology is an advanced display technology based on fine-grained area division and independent brightness control. Specifically, the backlight 1 is divided into multiple independent yet collaborative dimming zones, each equipped with an independent brightness adjustment device and control circuit. This division is not arbitrary but rather the result of in-depth optical research and precise calculations to ensure that each zone can accurately adjust its brightness according to actual display needs.
[0107] In practical applications, when there are differences in the content displayed from the left and right viewing angles of a dual-view display, local dimming technology can respond and adjust quickly. It analyzes the displayed content in each area in real time to determine the required brightness level for that area, and then dynamically adjusts the backlight brightness of the corresponding area. For example, when an area displays a bright image or text, local dimming technology automatically increases the backlight brightness of that area to ensure the content is clearly visible; conversely, when an area displays a dark scene with low brightness, the technology reduces the backlight brightness accordingly to avoid visual discomfort and energy waste caused by excessive brightness.
[0108] The advantages of local dimming technology are not only reflected in the precision and flexibility of brightness adjustment, but also in its significant improvement on the overall performance of dual-view displays. Firstly, it effectively enhances the contrast and depth of the dual-view display, making the displayed content more vivid, realistic, and three-dimensional. Secondly, this technology significantly reduces energy consumption by precisely controlling the brightness of each area, avoiding unnecessary energy waste and aligning with modern green and environmentally friendly development concepts. Furthermore, local dimming technology extends the lifespan of dual-view displays, reducing the risk of component aging and damage caused by prolonged high-brightness operation.
[0109] In summary, the local dimming technology employed in this embodiment brings revolutionary changes to the backlight 1. It not only improves the display performance and user experience of the dual-view display, but also provides strong support for the energy-saving and intelligent development of display technology. Through the application of local dimming technology, the dual-view display can more intelligently adapt to the needs of different display scenarios, bringing users a higher quality and more comfortable visual experience.
[0110] Although this application frequently uses terms such as dual-view display panel and privacy film, 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.
[0111] This utility model provides a novel dual-view display screen. By incorporating a privacy film on the dual-view display panel, it cleverly solves the problem of existing dual-view displays displaying content from one perspective when viewed from an angle of less than 20°. The privacy film allows the content of the dual-view display panel to be displayed normally within a viewing angle of 20°-90°, ensuring that users at both viewing angles can clearly see their respective information. However, within a non-viewing angle of less than 20°, the display content is obscured, presenting a blacked-out effect, effectively preventing incorrect information display. This innovative design significantly improves the privacy protection performance of the dual-view display screen while optimizing the user's viewing experience, avoiding the risk of information interference and leakage caused by viewing angle issues.
