Streaming media rearview mirror TECHNICAL FIELD
[0001] The present application relates to the technical field of rearview mirror, and in particular to a streaming media rearview mirror. BACKGROUND
[0002] The vehicle rearview mirror is generally installed on the vehicle for observing the situation behind the vehicle, and the streaming media rearview mirror mainly comprises a shell, a display module, a backlight module and a mounting bracket. The backlight module is used for emitting light to enable the display module to display normally. Then, a cover glass is used as a lens at the front end of the display module. The common lens assembly on the market is an EC mirror or an LC mirror.
[0003] The existing display module and backlight module are basically bonded by a plastic shell. Thus, a large bonding surface needs to be formed on the shell, and a large amount of glue is required. However, more importantly, if the bonding structure is attached to the plastic shell, the stress of the plastic shell will be increased, and the plastic shell is prone to falling off, thereby affecting the overall structural stability. SUMMARY
[0004] In order to overcome at least one of the defects of the prior art described above, the present application provides a streaming media rearview mirror. During assembly, a display screen is bonded to the back plate of a backlight module, and then a cover glass is bonded to the outside of the display screen and is attached to the opening end surface of the shell, so as to realize a frameless rearview mirror structure. When bonding, the cover glass peripheral edge is bonded to the opening peripheral wall end surface of the shell, thereby reducing the bonding amount on the shell.
[0005] The technical solution adopted by the present application to solve the problems is as follows:
[0006] A streaming media rearview mirror comprises:
[0007] A shell is provided with a cavity, and the cavity has an opening.
[0008] A display assembly comprises a backlight module, a display screen and a cover glass. The back plate of the backlight module is installed in the cavity. The display screen covers the end surface of the backlight module away from the back plate, and the peripheral edge of the display screen is bonded to the peripheral edge of the backlight module. The peripheral edge of the cover glass is bonded to the peripheral wall end surface of the opening, so that the cover glass can cover the peripheral wall of the shell after covering the opening, thereby realizing a frameless structure. The cover glass, the display screen and the backlight module are sequentially assembled into the cavity from the outside to the inside.
[0009] The present application has the following technical effects:
[0010] The cover glass is bonded to the outside of the display screen, while the periphery of the cover glass is bonded to the peripheral wall end face of the opening. In other words, after the display modules are assembled in sequence, they only need to be bonded to the housing through the periphery of the cover glass, reducing the bonding surface between the cover glass and the housing and reducing the plastic fixation of the housing. The main assembly structure relies on the internal structure of the housing, making the assembly structure more stable.
[0011] Furthermore, since the periphery of the cover glass fits into the end face of the opening's peripheral wall, the cover glass can cover the peripheral wall of the housing after the opening is sealed, thus preventing the peripheral wall of the housing's opening from being exposed by the cover glass and achieving a frameless structure.

Embodiments of the application
[0032] For better understanding and implementation, the technical solutions in the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application.
[0033] Referring to FIGS. 1-4, the application discloses a streaming media rearview mirror, comprising a shell 10 and a display assembly, wherein the shell 10 is provided with a cavity 101, and the cavity 101 is provided with an opening 103. The specific display assembly comprises a backlight module 20, a display screen 30 and a cover glass 40. When assembling the display assembly, the back plate 201 of the backlight module 20 is installed in the cavity 101, the display screen 30 is capped on the end face of the backlight module 20 away from the back plate 201 and adhered to the backlight module 20, and the periphery of the display screen 30 is adhered to the periphery of the backlight module 20. The cover glass 40 is capped on the end face of the display screen 30 away from the backlight module 20, that is, the cover glass 40, the display screen 30 and the backlight module 20 of the display assembly are sequentially assembled into the cavity 101 of the shell 10 from outside to inside, and the cover glass 40 is capped at the position of the opening 103, and the periphery of the cover glass 40 is adhered to the end face of the periphery wall of the opening 103.
[0034] Alternatively, the cover glass 40 is capped on the end face of the display screen 30 away from the display screen 30 and adhered to the periphery of the display screen 30; or the cover glass 40 is capped on the end face of the display screen 30 away from display screen 30 and adhered to the entire end face of the display screen 30; or the cover glass 40 is arranged opposite to the display screen 30 but not directly assembled and connected.
[0035] On the basis of the above structure, when the streaming media rearview mirror of the application is used, the backboard 201 of the backlight module 20 is installed into the cavity 101 through the opening 103 of the shell 10, and is supported by the internal structure of the cavity 101. The display screen 30 and the cover glass 40 are sequentially attached. The display screen 30 is connected to the backlight module 20 by adhesion. Specifically, the periphery of the display screen 30 is adhered to the periphery of the backlight module 20. At the same time, the cover glass 40 is optionally adhered to the periphery of the display screen 30 or is attached to the outer side surface of the display screen 30. The periphery of the cover glass 40 is adhered to the end surface of the periphery wall of the opening 103. That is to say, after the display module is sequentially assembled, only the periphery of the cover glass 40 needs to be adhered to the shell 10, the adhesion surface of the cover glass 40 and the shell 10 is reduced, and the plastic fixing of the shell 10 is reduced. The assembly structure mainly relies on the structure inside the shell 10, and the assembly structure is more stable.
[0036] In addition, since the periphery of the cover glass 40 is attached to the end surface of the periphery wall of the opening 103, the cover glass 40 can cover the periphery wall of the shell 10 after covering the opening 103. Therefore, the periphery wall of the opening 103 of the shell 10 can be prevented from being exposed by the cover glass 40, and a frameless structure is realized.
[0037] Further, a first limiting piece can be arranged in the cavity 101, and a second limiting piece is arranged on the backboard 201 of the backlight module 20. After the backboard 201 of the backlight module 20 is assembled into the cavity 101, the second limiting piece and the first limiting piece abut to form an adhesion interval between the periphery of the cover glass 40 and the end surface of the periphery wall of the opening 103. That is to say, after the backlight module 20 is assembled into the cavity 101 of the shell 10, the assembly position and the assembly height of the backlight module 20 in the cavity 101 remain consistent due to the abutment of the first limiting piece and the second limiting piece. Therefore, the assembly height and the assembly position of the display screen 30 and the cover glass 40 assembled on the basis of the backlight module 20 are relatively fixed after the backlight module 20 is assembled in place. Therefore, the cover glass 40 can form an adhesion interval with the end surface of the periphery wall of the opening 103 of the shell 10. The adhesion interval can have an adhesion material layer, so that the cover glass 40 can be adhered by the adhesion material layer on the periphery after being attached to the display screen 30.
[0038] It should be noted that the adhesion material layer is a foam adhesive layer 50. After the foam adhesive layer 50 is filled between the cover glass 40 and the periphery wall of the opening 103 of the shell 10, adhesion can be realized, and dust and water can be prevented from entering the inside through the adhesion interval between the cover glass 40 and the end surface of the shell 10.
[0039] Further, the first limiting member is a limiting groove 1011, and the second limiting member is a limiting column 2011, so that after the backlight module 20 is assembled to the cavity 101, the back plate 201 of the backlight module 20 can be inserted into the limiting groove 1011 of the cavity 101 through the limiting column 2011 to achieve positioning.
[0040] Of course, the first limiting member can also be a positioning groove, and the corresponding second limiting member is a positioning column, so that the mutual abutting limiting of the positioning column and the positioning groove can also be achieved. In addition, the first limiting member and the second limiting member can also be implemented in the manner of mutual insertion of a limiting sleeve and a limiting rod, which can be selected according to actual needs.
[0041] Further, the first circular arc chamfer 401 is arranged on the outer side of the peripheral edge of the cover plate glass 40, which can form a circular arc surface on the peripheral edge of the glass to prevent the peripheral edge of the cover plate glass 40 from being sharp and cutting hands. After the peripheral edge formed by the circular arc surface of the cover plate 40 is attached to the end surface of the peripheral wall of the opening 103 of the shell 10, it smoothly connects towards the peripheral wall of the shell 10 and does not protrude from the structure of the shell 10.
[0042] More specifically, the second circular arc chamfer 102 can also be arranged on the outer side of the peripheral wall of the opening 103, which can also form a circular arc surface on the peripheral edge of the shell 10, so that the peripheral edge of the shell 10 is not sharp. The radius of the circular arc surface of the second circular arc chamfer 102 can be greater than or less than the radius of the circular arc surface of the first circular arc chamfer 401, so that the two circular arc chamfers are not easy to protrude after the cover plate glass 40 is sealed, and the overall visual effect is consistent.
[0043] If the radius of the second circular arc chamfer of the peripheral wall of the opening 103 of the shell 10 is greater than the radius of the circular arc surface of the first circular arc chamfer of the cover plate glass 40, the greater the radius, the longer the arc length relative to the radius, and the steeper the circular arc curve. Thus, the edge of the opening 103 of the shell 10 below is steeply inwardly recessed, and the edge of the cover plate glass 40 above is gently curved, so that the visual effect of the peripheral edge of the cover plate glass 40 is gentle and is not easily affected by the peripheral edge of the shell 10 below.
[0044] If the radius of the second circular arc chamfer of the peripheral wall of the opening 103 of the shell 10 is less than the radius of the circular arc surface of the first circular arc chamfer of the cover plate glass 40, the edge of the opening 103 of the shell 10 below is gently curved, and the edge of the cover plate glass 40 above is steeply curved, so that the visual effect of "no frame" is presented above the gently curved circular arc.
[0045] Further, the peripheral edge of the display screen 30 and the peripheral edge of the backlight module 20 are bonded by a double-sided adhesive layer 60, so that double-sided fixation can be achieved and the amount of glue used can be reduced.
[0046] Further, the double-sided adhesive layer 60 is a VHB double-sided adhesive, i.e., a double-sided adhesive tape made of polyacrylate, which has high adhesive strength.
[0047] Further, the inner circumferential wall of the cavity 101 is provided with a plurality of reinforcing ribs 104 which are distributed at intervals. Since the cavity 101 has a certain installation space inside, the strength of the shell 10 will be affected, especially the circumferential wall of the cavity 101 is easily affected by external factors and is prone to damage. Therefore, a plurality of reinforcing ribs 104 can be distributed on the inner circumferential wall of the cavity 101. The plurality of reinforcing ribs 104 at intervals can strengthen the inner circumferential wall of the shell 10, bear and disperse the force acting on the circumferential wall of the shell 10, so that the shell 10 has better strength and is more durable.
[0048] Referring to FIGS. 5-9, in the preferred embodiment of the present application, the cover glass 40 includes a protective layer 4 and a lens 2. Specifically, the protective layer 4 is arranged opposite to the lens 2, and the lens 2 is arranged opposite to the display screen 1. A first optical adhesive layer 3 is arranged between the display screen 1 and the lens 2.
[0049] In the preferred embodiment of the present application, the lens 2 has a first bonding surface, the display screen 1 has a second bonding surface, and the two sides of the first optical adhesive layer 3 are bonded to the first bonding surface and the second bonding surface, respectively. The first optical adhesive layer 3 covers the first bonding surface and the second bonding surface.
[0050] On the basis of the above structure, during assembly, the first optical adhesive layer 3 can be arranged on the second bonding surface of the display screen 1, and the first optical adhesive layer 3 covers the second bonding surface. Then, the first bonding surface of the lens 2 is arranged close to the second bonding surface and bonded to the first optical adhesive layer 3. During the bonding process, air bubbles and impurities are excluded to ensure the bonding effect and display effect.
[0051] When the streaming rearview mirror of the present application is used, the display screen 1 of the streaming rearview mirror emits light rays, which contain real-time image information of the rear of the vehicle. The light rays emitted by the display screen 1 first pass through the first optical adhesive layer 3 which is closely bonded to the display screen 1. After the light rays pass through the first optical adhesive layer 3, they reach the lens 2, which allows the light rays from the display screen 1 to pass through and continue to propagate forward.
[0052] It should be noted that there is a significant difference in refractive index between the air layer and the lens 2 or the display screen 1. When the light rays enter the air layer from the display screen 1 or enter the lens 2 from the air layer, the propagation direction of the light rays will be deflected due to the change in refractive index, i.e., refraction phenomenon occurs. This refraction phenomenon will cause the transmission path of the light rays to deviate, thereby affecting the transmission efficiency and accuracy of the light rays. Therefore, by arranging the first optical adhesive layer 3, the present application can eliminate the direct contact between the air layer and the lens 2 or the display screen 1, thereby reducing the influence of the difference in refractive index on the transmission of light rays.
[0053] Specifically, the first optical adhesive layer 3 can be an OCA, OCR or the like, which generally has high transparency, stable refractive index, excellent optical performance and the like. Since the refractive index of the first optical adhesive layer 3 is generally between the air and the lens 2 or the display screen 1, it plays a transitional role. When the light enters the optical adhesive layer from the display screen 1, due to the gradual change of the refractive index, the degree of refraction of the light will decrease; when the light enters the lens 2 from the optical adhesive layer, due to the gradual change of the refractive index, the degree of refraction of the light will further decrease. In this way, by setting the first optical adhesive layer 3, the refraction phenomenon of the light in the transmission process can be effectively reduced.
[0054] In addition, scattering phenomenon refers to the phenomenon that light is scattered in all directions when encountering non-uniform medium or interface in the transmission process. Non-uniform factors such as small particles, dust or bubbles that may exist in the air layer will cause scattering of light. The first optical adhesive layer 3 generally has high purity and uniformity, which can effectively reduce the influence of these non-uniform factors on light, thereby reducing the occurrence of scattering phenomenon.
[0055] Therefore, the refraction and scattering phenomena of light in the transmission process can be reduced, thereby improving the clarity and contrast of the image. The display effect of the streaming rearview mirror is significantly improved, and the driver can more clearly see the road condition information behind the vehicle. In addition, the display screen 1 and the lens 2 are tightly combined by full bonding, which enhances the connection stability and reduces the occurrence of color difference and glare problems.
[0056] Further, the thickness of the first optical adhesive layer 3 is H, and the value range of H is 0.2-0.5mm.
[0057] It should be noted that this value range is not randomly set, and it needs to consider the connection effect of the display screen 1 and the lens 2 and the display effect of the streaming rearview mirror.
[0058] Specifically, since the main role of the first optical adhesive layer 3 is to eliminate the air layer between the display screen 1 and the lens 2 to reduce the refraction and scattering phenomena of light in the transmission process. Therefore, the thickness H of the adhesive layer needs to be thin enough to ensure that the light can pass smoothly without excessive optical distortion. However, if the thickness H is set to be less than 0.2mm, the too thin adhesive layer may cause insufficient adhesion strength, affecting the stability of the display screen 1 and the lens 2. Therefore, it is necessary to ensure that the adhesive layer has sufficient adhesion strength while ensuring the optical performance.
[0059] Correspondingly, if the thickness H is set to be greater than 0.5 mm, the excessively thick adhesive layer can increase the amount of adhesive used, which not only increases the cost but also increases the weight. In addition, the excessively thick adhesive layer can cause the focal length to be too long, so that the imaging position of the rearview mirror is moved backward, thereby increasing the depth of field. The increase in the depth of field can affect the clarity of the image, resulting in a decrease in image quality.
[0060] Therefore, when the value of H is in the range of 0.2-0.5 mm, the adhesion strength between the display screen 1 and the lens 2 is ensured, and at the same time, the depth of field is not excessively increased, thereby ensuring the display effect of the image.
[0061] Preferably, H is 0.25 mm. The adhesive layer thickness of 0.25 mm provides sufficient adhesion strength. This makes the connection between the display screen 1 and the lens 2 more secure, which can avoid loosening or falling off due to vibration or impact. At the same time, the adhesive layer thickness of 0.25 mm is thin enough to ensure that the light remains smooth when passing through the adhesive layer, reducing optical distortion caused by refraction and scattering. This helps to maintain the consistency of optical transmission between the display screen 1 and the lens 2, improving the clarity of the image. Moreover, the adhesive layer thickness of 0.25 mm does not significantly change the focal length of the entire optical system, thereby maintaining the stability of the imaging position of the rearview mirror and avoiding the decrease in image quality caused by the increase in the depth of field.
[0062] Further, the lens 2 comprises a first glass substrate, and a first reflective polarizer is arranged on one side of the first glass substrate, and the first adhesive surface is formed on the first reflective polarizer. Referring to FIG. 6, the display screen 1 comprises a second glass substrate 11, and a first polarizer 12 is arranged on one side of the second glass substrate 11 facing the first glass substrate, and the second adhesive surface is formed on the first polarizer 12. The two sides of the first optical adhesive layer 3 are respectively bonded to the first reflective polarizer and the first polarizer 12.
[0063] On the basis of this structure, when the pixel points on the display screen 1 emit light and generate an image, the light passes through the first polarizer 12 to ensure the clarity and contrast of the image. The light then passes through the first optical adhesive layer 3 and the first reflective polarizer, and finally enters the driver's eyes.
[0064] When the streaming rearview mirror is used as a reflector, the light from the rear of the vehicle directly irradiates the first reflective polarizer of the streaming rearview mirror. The first reflective polarizer has a specific polarization direction, and only allows light with the same polarization direction to pass through and reflect. When the light irradiates the first reflective polarizer, the light with the same polarization direction is reflected. Finally, the reflected light enters the driver's eyes to form the image of the rear.
[0065] The first optical adhesive layer 3 can effectively bond the first reflective polarizer and the first polarizer 12 together to form a flat and stable optical interface, prevent them from loosening or falling off due to vibration, temperature change or external impact, and prevent warping.
[0066] It should be noted that the first reflective polarizer can be an RPM lens.
[0067] Further, the display screen 1 comprises a second polarizer 13, and the second polarizer 13 is attached to the side of the second glass substrate 11 away from the first glass substrate.
[0068] Therefore, through the joint action of the two layers of polarizers, only the light rays meeting the two polarization directions can be observed by the driver. This helps to reduce the interference of stray light and improve the color saturation and contrast of the image.
[0069] Further, the backlight module 20 comprises a backlight film, and the backlight film is attached to the side of the second polarizer 13 away from the second glass substrate 11.
[0070] On this basis, when the streaming rearview mirror needs to display an image during use, the backlight film starts to emit light. The light emitted by the backlight film passes through the second polarizer 13, the pixel points of the display screen 1 and the first polarizer 12, and finally projects onto the first reflective polarizer to form the image observed by the driver.
[0071] The backlight film can be a diffusion film, a brightness enhancement film (prism film), etc., which can provide stable and uniform backlight illumination for the display screen 1, so that the display can normally display images under the irradiation of the backlight.
[0072] Therefore, the backlight film is the main source of light emission of the display screen 1. The light emitted by it is modulated by the pixel points of the display screen 1, and under the joint action of the two layers of polarizers, a clear and distinct image can be formed.
[0073] In addition, the lens 2 can also be an LC lens or an EC lens. The application preferably adopts an LC mirror as the lens 2; specifically, in the LC mirror, it comprises two oppositely arranged first glass substrates, and a liquid crystal layer is arranged between the two first glass substrates. In use, the arrangement of liquid crystal molecules can be controlled by electronic signals to change the propagation path of light, thereby realizing various optical effects.
[0074] It should be noted that the display screen 1 also includes two layers of oppositely arranged second glass substrates 11, and a liquid crystal layer is also arranged between the two layers of second glass substrates 11, and in use, the arrangement direction of the liquid crystal molecules can be controlled by an electronic signal to change the light transmission degree, so as to realize the change of brightness and color of the pixels. Among them, the first glass substrate and the second glass substrate 11 can be light-transmitting glass.
[0075] Further, the display screen 1 and the lens 2 are arranged in the shell 10. Among them, the opening 103 is provided with a protective layer 4, and the periphery of the protective layer 4 is connected with the shell 10; and the protective layer 4 is arranged opposite to the lens 2.
[0076] Among them, the protective layer 4 can be a protective glass, which is usually made of transparent and wear-resistant materials to ensure good light transmission and durability.
[0077] Further, referring to FIGS. 7 and 8, a second optical adhesive layer 5 is arranged between the lens 2 and the protective layer 4. Specifically, the side of the lens 2 facing the protective layer 4 is provided with a third adhesive surface, and the protective layer 4 has a fourth adhesive surface. Among them, the two sides of the second optical adhesive layer 5 are respectively bonded with the third adhesive surface and the fourth adhesive surface.
[0078] On the basis of this structure, after the lens 2 is connected with the display screen 1, the second optical adhesive layer 5 can be arranged on the third adhesive surface of the lens 2, and then the fourth adhesive surface of the protective layer 4 is close to the third adhesive surface and bonded with the second optical adhesive layer 5.
[0079] Since the second optical adhesive layer 5 has excellent optical performance, it can ensure that the light transmission between the lens 2 and the protective layer 4 does not have obvious refraction, reflection or scattering phenomenon, so as to maintain the clarity and accuracy of the image. At the same time, through the bonding effect of the second optical adhesive layer 5, the lens 2 and the protective layer 4 can form a firm combination, improve the durability and stability of the entire streaming rearview mirror. In addition, the second optical adhesive layer 5 can also play a sealing role, effectively preventing water vapor and dust and other impurities from invading from the gap between the lens 2 and the protective layer 4, and protecting the electronic components and optical components inside the streaming rearview mirror from damage.
[0080] Among them, the second optical adhesive layer 5 can also be an OCA, OCR or other adhesive layer, and the setting thickness is 0.2-0.5mm, preferably 0.25mm. Thus, the lens 2 and the protective layer 4 have firm connection strength and appropriate depth of field.
[0081] Further, the side of the first glass substrate away from the second glass substrate 11 is provided with a third polarizer, and a third adhesive surface is formed on the third polarizer; wherein the protective layer 4 is a light-transmitting glass, and the two sides of the second optical adhesive layer 5 are respectively bonded with the light-transmitting glass and the third polarizer; in addition, the second optical adhesive layer 5 covers the third adhesive surface.
[0082] The third polarizer can control the polarization direction of light, reduce the reflection and scattering of light inside the streaming rearview mirror, and thus improve the clarity and contrast of the image. The second optical adhesive layer 5 has excellent bonding performance, which can firmly bond the light-transmitting glass (protective layer 4) and the third polarizer together, thereby improving the overall stability and durability of the streaming rearview mirror.
[0083] Therefore, the streaming rearview mirror provided by the present application has the following technical effects:
[0084] The first optical adhesive layer 3 fully bonds the first adhesive surface and the second adhesive surface, thereby eliminating the air layer between the lens 2 and the display screen 1. Since the refractive index of the first optical adhesive layer 3 is between the air and the lens 2 or the display screen 1, it plays a transitional role and can effectively reduce the refraction of light during transmission. At the same time, the display screen 1 and the lens 2 are tightly combined by full bonding, which not only enhances the connection stability, but also reduces the occurrence of chromatic aberration and glare problems.
[0085] Referring to FIGS. 10-16, in the preferred embodiment of the present application, the cover glass 40 includes an EC lens 100, specifically, the EC lens 100 and the display screen 300 are arranged adjacent to each other.
[0086] The EC lens 100 includes a third glass substrate 1001 and a fourth glass substrate 1002, and a gap is provided between the third glass substrate 1001 and the fourth glass substrate 1002, which is filled with an electrochromic liquid. The electrochromic liquid can undergo reversible color change when an external current is turned on, which is used to play a color adjusting role to change its optical properties such as reflectivity, transmittance and absorptivity, so that the streaming rearview mirror realizes automatic anti-glare function. In particular, the size of the gap between the third glass substrate 1001 and the fourth glass substrate 1002 is preferably 0.1 mm.
[0087] The display screen 300 is arranged adjacent to the EC lens 100, and the display screen 300 is arranged on the side of the fourth glass substrate 1002 away from the third glass substrate 1001. The backlight module 20 creates a uniform, suitable brightness and stable backlight environment for the display screen 300 by light source lighting, so that the display screen 300 can normally display clear and colorful images.
[0088] Referring to FIG. 10, the EC mirror 100 is provided with a second reflective polarizer 1003 on the side facing the display screen 300, and at least one second reflective polarizer 1003 is attached to the surface of the fourth glass substrate 1002 away from the third glass substrate 1001. Among them, the second reflective polarizer 1003 has high transmittance to the polarized light emitted by the display screen 300 in the working state. In the technical solution of the present application, when the display screen 300 does not emit polarized light, at this time the streaming rearview mirror is in the non-streaming mode (i.e. the mirror mode), the EC mirror 100 has high reflectivity, which can play the role of a mirror, and reflects the image behind the vehicle in a physical mirror mode. When the display screen 300 is working and emitting polarized light, at this time the streaming rearview mirror is in the streaming mode, the second reflective polarizer 1003 has high transmittance (theoretically up to 100%) to the polarized light emitted by the display screen 300, thereby presenting the rear image of the vehicle in a video mode.
[0089] Therefore, the EC mirror 100 of the present application cancels the coating film on any inner surface between the two glass substrates, and instead attaches the second reflective polarizer 1003 to the lower surface of the fourth glass substrate 1002. Under the premise of meeting the high transmittance of the streaming rearview mirror and meeting the high screen brightness index, without increasing the brightness of the display screen 300, the power consumption can be significantly reduced, and the surface temperature and screen temperature rise of the streaming rearview mirror can be greatly reduced. Further, since the second reflective polarizer 1003 is arranged on the surface of the fourth glass substrate 1002 away from the third glass substrate 1001, compared with the scheme of coating a reflective film on the inner surface between the two glass substrates of the traditional EC mirror, the design method of the present application can paste the second reflective polarizer 1003 after assembling the EC mirror 100 according to actual needs, or assemble the two glass substrates 1 after pasting the second reflective polarizer 1003, which is simple and flexible to operate, and can avoid the interference or influence of the reflective polarizer by the electrochromic liquid, thereby improving the stability of the EC mirror 100 during long-term use.
[0090] Preferably, the second reflective polarizer 1003 of the present application can adopt any one of RPM film, APF film or DBEF film, and preferably adopts RPM film.
[0091] The working principle of RPM film (Reflective Polarizing Mirror) determines that it can have both high reflectivity and high transmittance: its biggest difference from ordinary polarizers is that its surface has high reflectivity. When no light passes through the back of the RPM film, it can have a reflectivity of more than 40%, while ordinary polarizers are generally below 5%. When the display screen 300 behind the RPM film emits light, the RPM film can transmit the light emitted by the display screen 300. Since the emitted light is polarized, when the polarization direction of the RPM film is completely parallel to the polarization direction of the upper polarizer of the display screen 300, the RPM film can have a transmittance of nearly 100% for the polarized light of the display screen 300.
[0092] In a preferred embodiment of this application, a first conductive layer is provided on the side of the third glass substrate 1001 facing the electrochromic liquid, and a second conductive layer is provided on the side of the fourth glass substrate 1002 facing the electrochromic liquid. The first and second conductive layers are respectively attached to the inner sides of the third glass substrate 1001 and the fourth glass substrate 1002, and are in direct contact with the electrochromic liquid between the two glass substrates. Their main function is to ensure the passage of polarized light while connecting to an external power source or circuit. When an external current is applied, they provide electrical energy to the electrochromic liquid, causing a reversible color change, thus achieving a color-adjusting effect and altering its optical properties such as reflectivity, transmittance, and absorptivity. This enables the streaming media rearview mirror of this application to achieve functions such as automatic anti-glare.
[0093] Furthermore, both the first conductive layer and the second conductive layer are transparent conductive coatings, which are used to ensure that the polarized light emitted by the display screen 300 can pass through the third glass substrate 1001 and the fourth glass substrate 1002 while changing color after an applied current is applied.
[0094] Preferably, the electrochromic liquid described in this application may include organic electrochromic materials, inorganic electrochromic materials, and composite electrochromic materials, with composite electrochromic materials being the most preferred. The first conductive layer and the second conductive layer described in this application may preferably be transparent conductive layers formed from indium tin oxide (ITO) conductive glass.
[0095] In a preferred embodiment of this application, the display screen 300 includes a TFT module, and the TFT module and the EC lens 100 are arranged adjacent to each other. The main function of the TFT module is to convert the natural light generated by the backlight into polarized light, and then control the voltage of the liquid crystal layer to change the deflection direction of the liquid crystal, thereby controlling the "amount" of light passing through, ultimately forming an image. Specifically, after the assembly of the streaming media rearview mirror of this application is completed, the EC lens 100 is located at the opening 103 of the streaming media rearview mirror housing 10, and the TFT module is located in the inner cavity of the streaming media rearview mirror housing 10. The polarized light generated and converted by the TFT module, combined with the EC lens 100, achieves the image display effect.
[0096] In a preferred embodiment, the size of the second reflective polarizer 1003 is greater than or equal to the size of the TFT module, thereby ensuring that all polarized light generated and converted by the TFT module can be covered by the second reflective polarizer 1003. When the TFT module is working and emitting polarized light, the second reflective polarizer 1003 has a high transmittance effect on the polarized light emitted by the TFT module (theoretically up to 100%), thereby presenting the rear driving image in the form of a video image.
[0097] It is worth mentioning that the size of the second reflective polarizer 1003 and the TFT module mentioned in this application refers to their size in the plane extension direction, that is, their size in the length and width directions, rather than their thickness.
[0098] Referring to Figure 10, in the technical solution of this application, the EC lens 100 also includes an electrode sheet 400, which includes a positive electrode sheet and a negative electrode sheet, located on the same side of the EC lens 100. Specifically, the streaming media rearview mirror includes a display area and a non-display area (i.e., a black border area). If the positive and negative electrode sheets are placed on different sides of the EC lens 100, at least two black border areas need to be set for the installation positions of the two electrode sheets, resulting in poor overall display effect of the streaming media rearview mirror and inconvenience for processing and assembly. This application places the positive and negative electrode sheets on the same side of the EC lens 100, so that this side can be designated as the side with the wider black border area during installation, eliminating the need for other black border areas and optimizing the mirror display effect. Furthermore, placing the EC lens 100 on the same side also provides a wider area for the welding area of the FPC (flexible current plate), which is beneficial to the overall design and production operation of the EC lens 100.
[0099] Preferably, as shown in Figures 10-12, the positive electrode and the negative electrode are located on the same long side of the EC lens 100, which further facilitates the layout of components such as the circuit board and the overall space design of the streaming media rearview mirror.
[0100] Referring to Figures 11-13, in a preferred embodiment, the electrode sheet 400 is an L-shaped electrode sheet, which includes a first end and a second end. The end of the first end is connected to a first conductive layer, thereby electrically connecting the first conductive layer to the electrochromic liquid between the third glass substrate 1001 and the fourth glass substrate 1002. Specifically, the external circuit provides electrical energy to the electrochromic liquid through the L-shaped electrode sheet, causing the electrochromic liquid to undergo a reversible color change, which serves to adjust the color and change its optical properties such as reflectivity, transmittance, and absorptivity, thereby enabling the streaming media rearview mirror of this application to achieve functions such as automatic anti-glare.
[0101] Preferably, the first end can be connected to the first conductive layer by conductive adhesive, and the second end can be connected to the side surface of the fourth glass substrate 1002 away from the third glass substrate 1001 by double-sided adhesive.
[0102] Preferably, as shown in FIG13, the size of the third glass substrate 1001 is larger than the size of the fourth glass substrate 1002, so that the third glass substrate 1001 extends relative to the fourth glass substrate 1002 to form a connecting portion 10011, and the first end of the L-shaped electrode sheet is connected to the first conductive layer at the connecting portion 10011. The connecting portion 10011, formed by the third glass substrate 1001 extending relative to the fourth glass substrate 1002, serves two purposes: firstly, it provides a connection area for the electrical connection between the two L-shaped electrode sheets and the first conductive layer; secondly, it can be used to connect with the opening 103 of the rearview mirror housing 10 to realize the assembly of the EC lens 100. In specific installation, the connecting portion 10011 corresponds to the opening 103 of the rearview mirror housing 10, and the two are bonded and fixed together using optical adhesive.
[0103] Furthermore, the EC lens 100 also includes at least two flexible circuit boards, which are connected to the other side of the second end of the L-shaped electrode sheet via an ACF hot-pressing process, that is, connected to the side of the second end of the L-shaped electrode sheet away from the fourth glass substrate 1002. After connection, the two flexible circuit boards and the two electrode sheets 400 are positioned correspondingly on the same side of the EC lens 100 (that is, the side with a wider black border area), providing a wider area for the welding area of the flexible circuit boards, which is beneficial for optimizing the display effect, overall design and production operation of the EC lens 100.
[0104] Therefore, the streaming media rearview mirror provided in this application has the following technical effects:
[0105] 1) The EC lens 100 includes a third glass substrate 1001, a fourth glass substrate 1002, and an electrochromic liquid filled between the two. The electrochromic liquid undergoes a reversible color change when an external current is applied, which is used to adjust the color and change its optical properties such as reflectivity, transmittance and absorptivity to achieve functions such as automatic anti-glare.
[0106] 2) A second reflective polarizer 1003 is provided between the EC lens 100 and the display screen 300. When the polarized light of the display screen 300 is turned off, the rearview mirror is in non-streaming media mode. The EC lens 100 has high reflectivity and can act as a reflector to reflect the rear view image in a physical mirror manner.
[0107] 3) When the display screen 300 is working and emits polarized light, the rearview mirror is in streaming media mode. The second reflective polarizer 1003 has a high transmittance (theoretically up to 100%) effect on the polarized light emitted by the display screen 300, thereby presenting the rear driving image in the form of a video image. Therefore, this application achieves high transmittance performance of the rearview mirror and meets the high screen brightness index without increasing the backlight brightness, which can significantly reduce power consumption and greatly reduce the outer surface temperature and screen temperature rise of the streaming media rearview mirror.
[0108] 4) The second reflective polarizer 1003 is disposed on the surface of the fourth glass substrate 1002 away from the third glass substrate 1001. Compared with the traditional EC lens scheme of coating a reflective film on the surface between two glass substrates, the design of this application can attach the second reflective polarizer 1003 after assembling the EC lens 100 according to actual needs, or attach the second reflective polarizer 1003 and then assemble the two glass substrates. The operation is simple and convenient, and it can avoid the interference or influence of the electrochromic liquid on the second reflective polarizer 1003, thereby improving the stability of the EC lens 100 during long-term use.
[0109] Referring to Figures 14-16, in a preferred embodiment of this application, a third optical adhesive layer 200 is provided between the second reflective polarizer 1003 and the display screen 300. The second reflective polarizer 1003 has a fifth adhesive surface, and the display screen 300 has a sixth adhesive surface. The fifth and sixth adhesive surfaces are arranged opposite to each other, and the two sides of the third optical adhesive layer 200 are bonded to the fifth and sixth adhesive surfaces, respectively. The third optical adhesive layer 200 covers the fifth and sixth adhesive surfaces, so that it completely fills the gap between them, i.e., the gap between the EC lens 100 and the display screen 300. Through this structural design, seamless bonding between the opposite sides of the EC lens 100 and the display screen 300 can be achieved, eliminating the air layer between them and avoiding problems such as water fogging and large color differences between the display area and the non-display area caused by the presence of the air layer. Furthermore, compared to the frame-mount process, since the EC lens 100, display screen 300 and third optical adhesive layer 200 in the full-lamination solution are integrated into a whole, the refraction and reflection that occur at the bonding interface between the bonding surface of the third optical adhesive layer 200 and the EC lens 100 and between the bonding surface of the third optical adhesive layer 200 and the display screen 300 can be almost ignored. Therefore, no obvious discontinuity or color difference is visible to the naked eye, achieving a better integrated color visual effect and further optimizing the mirror display effect of the streaming media reflector.
[0110] Furthermore, compared to the frame-mounted solution, the EC lens 100 and the display screen 300 of this application can achieve a tight bond through the full bonding of the third optical adhesive layer 200, which enhances the connection stability between the two, makes the overall structure of the streaming media rearview mirror more compact, and improves the strength of the lens. Moreover, compared to the frame-mounted solution, the thickness of the third optical adhesive layer 200 in the full bonding solution adopted in this application can be set to be thinner, which is conducive to achieving a thinner and lighter mirror body design.
[0111] In particular, the thickness of the third optical adhesive layer 200 in this application is preferably set to 0.25 mm.
[0112] In one alternative, the third optical adhesive layer 200 is a transparent optical adhesive layer, which serves to bond the fifth adhesive surface and the sixth adhesive surface while ensuring that the polarized light emitted by the display screen 300 can pass through the third optical adhesive layer 200 and then through the EC lens 100.
[0113] Furthermore, the third optical adhesive layer 200 can be either OCA or OCR. Specifically, when the third optical adhesive layer 200 is OCA, it is a transparent tape-like structure, and the bonding process includes peeling, bonding, debubbling, and UV curing. When the third optical adhesive layer 200 is OCR, since it is liquid, it needs to be left to cure for a period of time after bonding.
[0114] Referring to Figure 15, in a preferred embodiment, the EC lens 100 further includes at least two first flexible circuit boards 1004. The two first flexible circuit boards 1004 are connected to the positive electrode sheet and the negative electrode sheet respectively via an ACF thermoforming process. After connection, the positions of the two first flexible circuit boards 1004 and the two electrode sheets correspond to each other and are located on the same side of the EC lens 100 (i.e., the side with the wider black border area), providing a wider area for the welding area of the first flexible circuit boards 1004, which is beneficial for optimizing the display effect, overall design, and production operation of the EC lens 100.
[0115] Referring to Figure 16, in a preferred embodiment, the display screen 300 includes a TFT module. The TFT module includes an upper polarizer 3001, an upper glass 3002, a lower glass 3003, and a lower polarizer 3004 arranged sequentially. The upper polarizer 3001 is bonded to a third optical adhesive layer 200. A second gap is provided between the upper glass 3002 and the lower glass 3003, and the second gap is filled with liquid crystal. The main function of the TFT module is to convert the natural light generated by the backlight module 20 into polarized light. Then, the deflection direction of the liquid crystal is changed by controlling the voltage of the liquid crystal between the upper glass 3002 and the lower glass 3003, thereby controlling the "amount" of light passing through, and finally forming an image. Specifically, the polarization directions of the upper polarizer 3001 and the lower polarizer 3004 are 90 degrees to each other. The space between the upper glass 3002 and the lower glass 3003 is filled with liquid crystal. By deflecting the liquid crystal, light from the lower polarizer 3004 can pass through the upper polarizer 3001 to form an image.
[0116] Furthermore, since the EC lens 100 is provided with a second reflective polarizer 1003, when the polarization direction of the second reflective polarizer 1003 is completely parallel to the polarization direction of the upper polarizer 3001 of the TFT module, the second reflective polarizer 1003 can have a transmittance of nearly 100% for the polarized light of the display screen 300.
[0117] Referring to Figure 16, in a preferred embodiment, the display screen 300 further includes a second flexible circuit board 3005. One end of the second flexible circuit board 3005 is connected to the lower glass 3003 through an ACF hot-pressing process, and the other end of the second flexible circuit board 3005 is connected to the main circuit board to realize the communication function.
[0118] Therefore, the streaming media rearview mirror provided in this application has the following technical effects:
[0119] 1) The EC lens 100 and the second reflective polarizer 1003 are bonded together by a third optical adhesive layer 200. The third optical adhesive layer 200 completely covers the fifth and sixth adhesive surfaces of the two surfaces, ensuring that it completely fills the gap between them. This achieves seamless bonding between the EC lens 100 and the display screen 300, eliminating air gaps and preventing issues such as fogging and significant color differences between the display and non-display areas. Furthermore, compared to frame-mounted solutions, the EC lens 100, display screen 300, and third optical adhesive layer 200 are integrated into a single unit in this fully bonded solution. Refraction and reflection at the bonding interface between the third optical adhesive layer 200 and the two adhesive surfaces are negligible, resulting in no noticeable discontinuity or color difference to the naked eye. This achieves a superior unified color visual effect and further optimizes the mirror display effect of the reflector.
[0120] 2) The EC lens 100 and the display screen 300 are tightly bonded together by the full bonding of the third optical adhesive layer 200, which can enhance the connection stability between the two, make the overall structure of the streaming media rearview mirror more compact, and improve the strength of the lens; and compared with the frame bonding solution, the third optical adhesive layer 200 in the full bonding solution is thinner, which is conducive to achieving a thinner and lighter mirror body design.
[0121] It should be noted that the display screen 30, display screen 1 and display screen 300 described in this application are the same structure in the streaming media rearview mirror.
