Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a rearview mirror and a vehicle. Background Technology

[0002] Streaming rearview mirrors, as a type of automotive accessory that integrates image capture and display technology, are gradually replacing traditional optical rearview mirrors as a key component of intelligent driving and driver assistance systems. They capture real-time images of the area behind the vehicle using a wide-angle camera mounted at the rear or top of the vehicle and transmit them to a display screen located within the driver's line of sight.

[0003] However, most of the related technologies for streaming media rearview mirrors suffer from one or more of the following problems: excessive overall weight, high cost, low processing yield, and obvious color difference at the splicing point between the glass cover and the LCD display module, resulting in poor visual integration and affecting aesthetics and unity. Utility Model Content

[0004] The purpose of this utility model is to provide a rearview mirror and vehicle to solve the problems in related technologies, such as obvious color difference at the splicing point between the glass cover and the liquid crystal display module of the streaming media rearview mirror, low processing yield, and high cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a rearview mirror, which includes: a liquid crystal display module, comprising an upper polarizing structure, a liquid crystal display body, and a lower polarizing structure arranged sequentially from top to bottom; the upper polarizing structure includes a brightness enhancement polarizer for transmitting and reflecting light; the brightness enhancement polarizer includes a layered composite brightness enhancement layer, a polarizing layer, and a substrate layer; the polarizing layer is disposed on the upper or lower surface of the substrate layer; and the brightness enhancement layer is disposed on the upper surface of the composite structure of the polarizing layer and the substrate layer; and a light-transmitting cover plate, the lower surface of which is fixedly attached to the upper surface of the brightness enhancement layer.

[0007] In one embodiment, the brightening layer includes a mirror film, which is laminated to the lower surface of the light-transmitting cover.

[0008] In one embodiment, the lower surface of the light-transmitting cover is bonded to the upper surface of the brightening layer via an adhesive layer.

[0009] In one embodiment, the adhesive layer is a polyvinyl alcohol-based resin aqueous solution adhesive layer or an aqueous two-component urethane emulsion adhesive layer.

[0010] In one embodiment, the brightening polarizer is an APF polarizer.

[0011] In one embodiment, the circumferential profile dimension of the light-transmitting cover is larger than the circumferential profile dimension of the liquid crystal display module to form a flange.

[0012] In one embodiment, a reflective layer is provided on a portion of the lower surface of the light-transmitting cover, the reflective layer being used to reflect incident light from above the reflective layer.

[0013] In one embodiment, the reflective layer extends circumferentially along the flange in a ring shape, and the width of the reflective layer is equal to or greater than the width of the flange.

[0014] In one embodiment, the reflective layer is a reflective coating or a reflective film.

[0015] Secondly, this utility model provides a vehicle that includes the rearview mirror of any of the above-mentioned solutions.

[0016] The beneficial effects of this utility model are as follows:

[0017] The rearview mirror and vehicle provided by this utility model are designed with an upper polarizing structure of the liquid crystal display module as a brightness-enhancing polarizer. The brightness-enhancing layer in the brightness-enhancing polarizer can effectively reflect light, and the polarization layer can effectively manage the polarization state of light entering and leaving the liquid crystal display body, reducing the reflection of ambient light, improving image contrast, and facilitating the provision of high transmittance and clear images in the bright screen state. The brightness-enhancing layer allows some of the light reflected by the polarization layer to be redirected and re-enter the display system by changing its polarization state, realizing light recycling. This not only improves brightness but also enhances the management of reflected light without significantly reducing transmittance, achieving higher light efficiency and better display effect, making the background scene clearly visible and facilitating clear observation of the situation inside and outside the vehicle. At the same time, it reduces the impact on the intensity of transmitted light, making it easier to display images from the external camera in high definition, improving the balance between reflectivity and transmittance. The upper polarizing structure facilitates the achievement of high reflectivity and high transmittance. In the off state, the upper polarizing structure is bonded to the light-transmitting cover through the brightening layer, allowing light to be reflected or passed through more evenly, reducing scattering. This effectively reduces color difference or boundaries, improving the overall aesthetics and visual integration of the product. The interior and rear exterior environments can be clearly observed in both on and off states. This reduces the cost increase and yield loss caused by applying RPM film to the glass cover, simplifies the process, reduces material costs, and improves production efficiency and product yield.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] In the design process of the streaming media rearview mirror, the inventors attempted to use a double-layer glass cover with an RPM film sandwiched between the upper and lower glass covers. This double-layer glass cover with RPM film was positioned above the LCD module, with the back of the lower glass cover bonded to the LCD module. However, due to the need for two glass covers, the overall weight was excessive, increasing costs. Furthermore, there was a noticeable color difference at the joint between the glass cover and the LCD module, resulting in poor visual integration and affecting aesthetics and overall unity.

[0033] If the lower glass cover is reduced and an RPM film is bonded to the back of the upper glass cover, the RPM film is directly bonded to the back of the upper glass cover, while the LCD module is bonded to the RPM film with a full-bonding adhesive. However, defects are easily generated during the bonding process, which leads to a decrease in the overall product yield. The RPM film is expensive and has a low yield, which increases the processing cost.

[0034] like Figures 1 to 2 As shown, based on the above, an embodiment of the first aspect of this utility model provides a rearview mirror, which includes a liquid crystal display module 1 and a light-transmitting cover plate 2. The liquid crystal display module 1 includes an upper polarizing structure 11, a liquid crystal display body 12, and a lower polarizing structure 13 arranged sequentially from top to bottom. The upper polarizing structure 11 includes a brightness enhancement polarizer 111, which is used to transmit and reflect light. The brightness enhancement polarizer 111 includes a layered composite brightness enhancement layer 111a, a polarizing layer 111c, and a substrate layer 111b. The polarizing layer 111c is disposed on the upper or lower surface of the substrate layer 111b, and the brightness enhancement layer 111a is disposed on the upper surface of the composite structure of the polarizing layer 111c and the substrate layer 111b. The lower surface of the light-transmitting cover plate 2 is fixedly attached to the upper surface of the brightness enhancement layer 111a of the upper polarizing structure 11.

[0035] The liquid crystal display module 1 refers to the core component forming the liquid crystal display, including components arranged sequentially from top to bottom such as the upper polarizing structure 11, the liquid crystal display body 12, the lower polarizing structure 13, and the backlight unit. The liquid crystal display module 1 requires the upper polarizing structure 11 and the lower polarizing structure 13 to work together. In related technologies, the upper polarizing structure 11 and the lower polarizing structure 13 typically use ordinary polarizers to control the polarization direction of a specific light beam. When natural light passes through the polarizer, light whose vibration direction is perpendicular to the transmission axis of the polarizer is absorbed, leaving only polarized light whose vibration direction is parallel to the transmission axis of the polarizer. In the liquid crystal display module 1, the upper polarizing structure 11 and the lower polarizing structure 13 are respectively attached to both sides of the liquid crystal display body 12. The lower polarizing structure 13 is used to convert the light beam generated by the backlight into polarized light, and the upper polarizing structure 11 is used to analyze the polarized light after being electro-modulated by the liquid crystal in the liquid crystal display body 12, generating contrast between light and dark, thereby producing the displayed image. The imaging of the liquid crystal display module 1 relies on the polarized light converted by the upper polarization structure 11 and the lower polarization structure 13 to display the image.

[0036] The liquid crystal display body 12 may include a glass substrate, a color filter and a black frame, a protective film, a common electrode, an alignment film, liquid crystal and thin film transistors and pixel electrodes. The liquid crystal display body 12 is used to modulate polarized light through liquid crystal. The structure and modulation principle of the liquid crystal display body 12 are similar to those of the liquid crystal display body 12 in the liquid crystal display module 1 in the prior art. It is sufficient to modulate polarized light through liquid crystal, and will not be described in detail here.

[0037] The substrate layer 111b serves as the basic support layer for the brightness-enhancing polarizer 111. It can be a transparent polymer film, such as polyethylene terephthalate or polycarbonate. The substrate layer 111b provides stable support and protection for the brightness-enhancing layer 111a without affecting light transmission. The polarization layer 111c is the core component of the brightness-enhancing polarizer 111, responsible for converting natural light into polarized light. Through a specific arrangement, the polarization layer 111c allows light of one polarization direction to pass through while reflecting or absorbing light of another polarization direction, achieving a polarization effect. The polarization layer 111c can be disposed on the upper or lower surface of the substrate layer 111b. The brightness-enhancing layer 111a can be disposed on the upper surface of the composite structure of the polarization layer 111c and the substrate layer 111b, reflecting light to improve reflectivity. Furthermore, the brightness-enhancing layer 111a can redirect some of the light reflected by the polarization layer 111c, changing its polarization state and allowing it to pass through the polarization layer 111c again, achieving light recycling and improving brightness and transmittance.

[0038] The light-transmitting cover 2 refers to the protective layer located above the liquid crystal display module 1. It has high light transmittance and a certain mechanical strength, and is used to protect the liquid crystal display module 1 from external damage. At the same time, it has good light transmission performance, and is made of materials such as glass or plastic. The lower surface of the light-transmitting cover 2 is fixedly attached to the upper surface of the brightness enhancement layer 111a. This means that the upper surface of the brightness enhancement layer 111a and the lower surface of the light-transmitting cover 2 can be physically contacted and optically connected by using adhesives, bonding adhesives or other methods. This ensures that there are no air gaps between the two, avoids light scattering and loss at the interface, and improves the display effect.

[0039] In this embodiment, the upper polarizing structure 11 of the liquid crystal display module 1 can be designed as a brightness enhancement polarizer 111. The brightness enhancement polarizer 111 can be a sheet structure used for transmitting and reflecting light, and has sufficient supporting strength. The brightness enhancement layer 111a in the brightness enhancement polarizer 111 can effectively reflect light, and the polarization layer 111c can effectively manage the polarization state of light entering and leaving the liquid crystal display body 12, reduce the reflection of ambient light, improve image contrast, and facilitate the provision of high transmittance and clear images in the bright screen state. The brightness enhancement layer 111a makes the part reflected by the polarization layer 111c more transparent. The light can be redirected and re-enter the display system by changing its polarization state, achieving light recycling. This not only improves brightness but also enhances the management of reflected light without significantly reducing transmittance, resulting in higher luminous efficiency and better display effects. This makes the background clearly visible, facilitating clear observation of the interior and rear environment of the vehicle. Simultaneously, it reduces the impact on the intensity of transmitted light, making it easier to display images from the exterior camera in high definition. The upper polarizing structure 11 facilitates a balance between reflectivity and transmittance, achieving both high reflectivity and high transmittance. In the screen-off state, the upper polarizing structure 11 is bonded to the light-transmitting cover 2 through the brightening layer 111a, allowing light to be reflected or passed through more evenly, reducing scattering and effectively minimizing color difference or boundaries. This improves the overall aesthetics and visual integration of the product, ensuring clear observation of the interior and rear environment of the vehicle in both screen-on and screen-off states. This embodiment reduces the cost increase and yield loss caused by applying RPM film to the glass cover, simplifies the process, reduces material costs, improves production efficiency and product yield, and solves the problems of obvious color difference, low processing yield and high cost at the splicing point between the glass cover and the liquid crystal display module of the streaming media rearview mirror in related technologies.

[0040] In one optional embodiment, the brightening layer 111a includes a mirror film, which is laminated on the lower surface of the light-transmitting cover plate 2. That is, the mirror film is located on the top layer of the brightening polarizer 111, which helps to reduce color difference or boundaries, improves the overall aesthetics and visual integration of the product, and the high reflectivity of the mirror film can effectively reflect ambient light, making the background scene clearly visible and facilitating clear observation of the situation inside and outside the vehicle. At the same time, it reduces the impact on the intensity of transmitted light, which is conducive to balancing the image of the high-definition display of the vehicle's external camera and improving the balance between reflectivity and transmittance. The upper polarizing structure 11 facilitates the achievement of high reflectivity and high transmittance.

[0041] like Figures 1 to 2 As shown, in some embodiments, the lower surface of the light-transmitting cover plate 2 is bonded to the upper surface of the brightness enhancement layer 111a via an adhesive layer 3, resulting in a strong connection. This improves the structural integrity and stability between the components and reduces the risk of displacement or separation due to vibration or external impact during vehicle operation. The adhesive layer 3 reduces the air gap between the light-transmitting cover plate 2 and the brightness enhancement polarizer 111, reducing light reflection and scattering at the interface, thereby improving optical transparency and display effect. It also helps maintain the polarization state of the light, facilitating the consistency of the distance and optical performance between the light-transmitting cover plate 2 and the brightness enhancement polarizer 111.

[0042] Optionally, the adhesive layer 3 can be a polyvinyl alcohol-based resin aqueous solution adhesive layer or a water-based two-component urethane emulsion adhesive layer, both of which have high transparency and good optical properties, can minimize the reflection and refraction loss of light at the interface, improve the display effect and reflection clarity of the rearview mirror, and have high bonding strength and stable connection.

[0043] like Figures 1 to 2 As shown, in some embodiments, the brightness-enhancing polarizer 111 can be an APF polarizer (Advanced Polarizer Film, multilayer reflective polarizer). Through its unique multilayer optical structure, the APF polarizer enhances the brightness of the screen at wide viewing angles, maintaining good readability even in strong sunlight, thus improving driving safety. The APF polarizer can recover and reuse light that would otherwise be wasted, improving display efficiency. The thin design of the APF polarizer allows for a thinner and lighter overall structure for the rearview mirror, reducing wind resistance and energy consumption, and improving the portability and installation flexibility of the device. By improving light utilization efficiency and controlling polarized light, the APF polarizer can enhance image clarity and color saturation, providing a higher quality and more realistic visual experience. The upper polarization structure 11 of the liquid crystal display module 1, by employing an APF polarizer, reduces the additional RPM film application steps, improving production yield and reducing manufacturing costs.

[0044] Optionally, the APF polarizer may include a stacked composite phase retardation layer, a polarization layer 111c, and a semi-transparent, semi-reflective layer. The phase retardation layer may serve as a substrate layer 111b, and the semi-transparent, semi-reflective layer may serve as a brightness enhancement layer 111a. The semi-transparent, semi-reflective layer, phase retardation layer, and polarization layer 111c may be arranged sequentially from top to bottom. The polarization layer 111c controls the polarization direction of the backlight, ensuring the clarity of the displayed image and performing initial polarization filtering on ambient light. The phase retardation layer adjusts the polarization phase of the reflected light to avoid interference with the transmitted light, reducing ghosting or blurring. The semi-transparent, semi-reflective layer balances the intensity of the transmitted and reflected light, making both distinguishable to the human eye. Additionally, the APF polarizer may include an anti-reflective coating to reduce light reflection loss on the surface of the APF polarizer and improve the reflection efficiency of the background scene.

[0045] An APF (Aspect-Reflecting Power Filter) polarizer uses a combination of multiple optical films, including a phase retardation layer, a polarization layer 111c, and a semi-transparent / semi-reflective layer, to separate light into transmitted and reflected light. Transmitted light refers to the polarized light from the backlight source, which is modulated by the APF to form the displayed image. Reflected light refers to ambient light (unpolarized or with a different polarization direction) from the background scene, which is processed by the semi-transparent / semi-reflective layer, repolarized, and then enters the eye to present the background image. The APF polarizer, by incorporating a phase retardation layer, ensures a 90° phase difference between the polarization directions of the reflected and transmitted light, preventing image confusion caused by the overlap of reflected and transmitted light in the human eye. For example, the backlight light becomes vertically polarized (transmission imaging) after passing through the polarization layer 111c; the background reflected light becomes horizontally polarized after reflection by the APF. Because their polarization directions are perpendicular, the two are separated in the human eye, forming independent visual signals. APF polarizers, by setting a semi-transparent and semi-reflective film, can adjust their transmittance and reflectance (e.g., 70% transmittance and 30% reflectance), so that the transmitted light and reflected light are superimposed on the human eye's retina, forming a composite visual effect of the displayed image and background scene.

[0046] like Figures 1 to 3 As shown, in some embodiments, the circumferential profile dimension of the light-transmitting cover 2 is larger than that of the liquid crystal display module 1 to form a flange 21. The flange 21 can be used for fixed connection with external components. The flange 21 provides additional physical support, enhances the connection strength between the light-transmitting cover 2 and external components, reduces the impact of external impacts such as vehicle vibration and collisions on the liquid crystal display module 1, and ensures the stability of the overall structure of the rearview mirror and the safety of the display module.

[0047] like Figures 1 to 3As shown, in some embodiments, a reflective layer 22 is provided on a portion of the lower surface of the light-transmitting cover plate 2. The reflective layer 22 is used to reflect incident light from above the reflective layer 22, so that light can be reflected even when the screen is off, thereby improving the overall visual effect of the display area of ​​the liquid crystal display module 1 below the light-transmitting cover plate and the non-display area outside the liquid crystal display module 1 when the screen is off.

[0048] In one optional embodiment, the reflective layer 22 extends circumferentially along the flange 21 in a ring shape, and the width of the reflective layer 22 is equal to or greater than the width of the flange 21. The ring-shaped reflective layer 22 provides a uniform reflection effect when the screen is off, making the entire rearview mirror surface appear more consistent and smooth. This reduces potential visual differences between the liquid crystal display module 1 and the light-transmitting cover 2, improving the aesthetics and overall appearance of the rearview mirror when the display function is not in use. The ring-shaped reflective layer 22 also reduces the amount of external light entering the device through the edge of the light-transmitting cover 2, reducing display interference caused by oblique light, such as halos or stray light phenomena, thus improving display quality. The matching width of the reflective layer 22 with the flange 21 ensures that the reflection and display effects of the rearview mirror surface remain consistent when viewed from multiple angles, reducing visual abruptness and improving the user's visual experience and comfort.

[0049] The reflective layer 22 can be a reflective coating or a reflective film. The reflective coating can be deposited on the lower surface of the light-transmitting cover plate 2, which is stable and easy to process.

[0050] Optionally, the reflective coating can be a cadmium coating. Cadmium coating has high reflectivity, allowing the lower surface of flange 21 and the display area of ​​the liquid crystal display module 1 to blend seamlessly when the screen is off, achieving a superior visual aesthetic. Cadmium coating exhibits good chemical and physical stability under various environmental conditions, such as temperature changes and humidity fluctuations, and will not easily oxidize or corrode, ensuring that the reflective layer 22 maintains high performance over a long period and extending the service life of the rearview mirror. Cadmium coating has good conductivity, which can be used for electrostatic protection, reducing the potential damage of static electricity to the liquid crystal display module 1 and internal electronic components, improving the reliability and stability of the equipment. Cadmium coating can be processed using various coating processes such as electroplating and vacuum coating, exhibiting good process adaptability and facilitating large-scale production and processing control. The smooth surface of the cadmium coating does not easily attract dust and stains, making the rearview mirror easier to clean during use and maintaining good visual effects and reflective performance. The uniform reflective characteristics of the cadmium coating reduce light scattering and unevenness in edge areas, providing a more consistent reflective effect, thereby improving the overall visual experience of the rearview mirror. In the event of a collision, the cadmium coating can provide a certain degree of impact resistance, reducing the risk of fragments flying after the light-transmitting cover 2 breaks, thus improving the safety performance of the equipment.

[0051] Optionally, the reflective layer 22 may also be an aluminum-plated layer or a silver-plated layer, or a reflective film layer, for example, a mirror film layer.

[0052] A second aspect of this utility model provides a vehicle including the rearview mirror of any of the above embodiments.

[0053] Since the vehicle of this utility model embodiment includes the aforementioned rearview mirror, it possesses all the advantages and beneficial effects of the above embodiments, which will not be repeated here.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
