Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a display screen module, a display screen device, and a vehicle. Background Art

[0002] With the development of automotive smart cockpit technology and people's increasing requirements for the interactive experience of automotive smart cockpits, higher and higher demands are being placed on the appearance of in-vehicle displays.

[0003] Existing display screens mainly have two solutions: installing front and rear shells as the appearance parts of the screen module, and directly using the die-casting parts in the screen module as the appearance parts.

[0004] The former will make the display screen bulky due to the existence of the front and rear shells, while the latter is not easy to customize in shape and cannot meet people's demands for the appearance of the display screen. Summary of the Invention

[0046] In the embodiments of the present application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of the features.

[0047] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0048] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0049] In the embodiments of the present application, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0050] The present application provides a display terminal, which can be a mobile phone, tablet computer, television, vehicle, advertising screen, industrial equipment, etc. The display terminal can be a display device for displaying information. The display terminal can also serve as a display carrier for mounting and carrying a display device to express and convey information. The present application describes the embodiment in detail using a vehicle as the display terminal.

[0051] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. The vehicle 1000 may be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, an extended-range electric vehicle, a fuel vehicle, etc. The vehicle 1000 may also be a car, a van, a bus, a truck, a trailer, a special operation vehicle, etc.

[0052] The vehicle 1000 may include a body 100 and wheels 200. The body 100 is used for passengers to sit and carry items, and the wheels 200 are installed under the body 100 to carry the body 100 and can roll on the road to enable the vehicle 1000 to travel.

[0053] The present application also provides a display screen device 300 that can be mounted on the vehicle body 100. In some possible structural designs, the display screen device 300 can be mounted on the exterior of the vehicle body 100 to display information to the outside world, such as on an advertising vehicle displaying advertising information or on a bus displaying route information. In other possible structural designs, the display screen device 300 can be mounted inside the cab of the vehicle body 100 to display driving information of the vehicle 1000, such as the driving status of the vehicle 1000 and navigation information, to the driver and passengers.

[0054] Please refer to Figure 2 , Figure 2 This is a structural diagram of a display screen device 300 provided in an embodiment of the present application. The display screen device 300 may include a display screen module 01 . The display screen module 01 is mainly used to process light source information and display information.

[0055] Please refer to Figure 3 , Figure 3 This is a structural schematic diagram of a display screen module 01 provided in an embodiment of the present application. The display screen module 01 provided in an embodiment of the present application may include a screen structure 1 and a light guide structure 2, and the light guide structure 2 is used to transmit light to the screen structure 1.

[0056] In order to support and protect the screen structure 1 and the light guide structure 2, the display screen module 01 may also include a support member 4, which is provided with a accommodating cavity and an opening connected to the accommodating cavity. The light guide structure 2 and the screen structure 1 can be arranged in the accommodating cavity through the opening, thereby protecting the light guide structure 2 and the screen structure 1 and preventing the light guide structure 2 and the screen structure 1 from being bumped or damaged during production, transportation and use.

[0057] In display module 01, a middle frame 3 is typically disposed between screen structure 1 and light guide structure 2. At least a portion of this middle frame 3 is disposed between the two structures, and a communication channel is provided between the light guide structure 2 and the screen structure 1, allowing light from the light guide structure 2 to pass through this communication channel and be displayed on the screen structure 1. This middle frame 3 can be disposed at the edge of the screen structure 1 and the light guide structure 2 to block light emitted from the edge of the light guide structure 2, preventing it from being transmitted to the screen structure 1. This reduces the possibility of light leakage at the edge of the display and improves the display yield.

[0058] In addition, the middle frame 3 is arranged between the light guide structure 2 and the screen structure 1. After the middle frame 3 is installed and fixed, the light guide structure 2 can be positioned to prevent the light guide structure 2 from being displaced during production and transportation, causing the display screen to fail, thereby improving the reliability of the display screen.

[0059] Please refer to Figure 4 , Figure 4 This is a structural diagram of a display screen module 01 in the prior art. The screen structure 1, the light guide structure 2, and the middle frame 3 are all arranged in the accommodating cavity of the support member 4. At least a portion of the support member 4 is arranged around the light guide structure 2 and the screen structure 1 to form the frame of the display screen module 01. Compared with the prior art method of providing a separate shell as a frame member, the number of parts of the display screen module 01 can be reduced, and the frame size of the display screen module 01 can be directly determined by the size of the support member 4. Since the support member 4 is a single structural member, it can directly serve as the frame of the display screen module 01 without the need to provide a connecting structure or other components to cooperate. The thickness of the frame of the display screen module 01 can be reduced to achieve a lightweight design. However, as the frame of the display screen module 01, the support member 4 is limited by the surface process. The support member 4 cannot meet the user's requirements for two-color or high-gloss matte styling, and the appearance effect is poor.

[0060] Please continue to refer to Figure 3 The middle frame 3 of the display screen module 01 provided in the embodiment of the present application is arranged at the opening of the support member 4. The middle frame 3 can be connected between the support member 4 and the screen structure 1, and at least part of the middle frame 3 is arranged around the screen structure 1.

[0061] In this way, at least a portion of the middle frame 3 is connected to the support member 4 and is arranged around the screen structure 1. Together with the support member 4, it can form the frame of the display screen module 01. Compared with the existing technology, the shell can be reduced, and a lightweight design of the display screen module 01 can be achieved. Since at least a portion of the middle frame 3 is arranged around the screen structure 1 and the middle frame 3 is connected to the support member 4, no other matching structure is required. Therefore, the frame thickness of the display screen module 01 is determined by the first spacing. The first spacing is the distance between the surface of the middle frame 3 and the support member 4 away from the screen structure 1 and the surface of the screen structure 1 close to the middle frame 3. By reducing the size of the middle frame 3 and the support member 4, the frame size of the display screen module 01 can be reduced. In this way, while retaining the middle frame 3 to improve the reliability of the display screen module 01, a narrow frame design of the display screen module 01 can be achieved.

[0062] In addition, the middle frame 3 and the support member 4 can be surface-treated separately to achieve customized design of the appearance, meeting the user's needs for dual colors and other appearance solutions such as highlight processing.

[0063] In some embodiments of the present application, the middle frame 3 may include a light blocking portion 31 and a first connecting portion 32, the light blocking portion 31 is arranged between the screen structure 1 and the light guiding structure 2, and the light blocking portion 31 is provided with a light-transmitting channel connected to the accommodating cavity; the first connecting portion 32 surrounds the light blocking portion 31 and is connected between the support member 4 and the screen structure 1, and part of the first connecting portion 32 surrounds the screen structure 1.

[0064] The light blocking portion 31 can be arranged between the screen structure 1 and the light guiding structure 2, and is provided with a light-transmitting channel connected to the accommodating cavity, so that the light of the light guiding structure 2 arranged in the accommodating cavity can be displayed on the screen structure 1 through the light-transmitting channel, and the light of the light guiding structure 2 cannot be transmitted to the screen structure 1 through the light blocking portion 31, thereby blocking part of the light and reducing light leakage at the edge of the screen.

[0065] The first connecting portion 32 is arranged around the light blocking portion 31 and is connected between the support member 4 and the screen structure 1. In this way, the light blocking portion 31 can be positioned through the connection of the first connecting portion 32, so that the light blocking portion 31 can position the light guiding structure 2. Part of the first connecting portion 32 is arranged around the screen structure 1, and the first connecting portion 32 can form a frame of the display screen module 01, thereby protecting the screen structure 1. By selecting the material of the first connecting portion 32 and performing appearance treatment on the first connecting portion 32, the first connecting portion 32 and the support member 4 can present different appearance schemes to meet the user's appearance requirements.

[0066] In addition, since the first connecting portion 32 is connected between the support member 4 and the screen structure 1, and part of the first connecting portion 32 surrounds the screen structure 1, by reducing the size of the first connecting portion 32 along the direction from the screen structure 1 to the first connecting portion 32, the size of the frame of the display screen module 01 can be reduced, making the display screen module 01 lighter and thinner.

[0067] In some embodiments, the first connecting portion 32 and the light shielding portion 31 are integrated into one structure, thereby reducing the number of parts, simplifying the structure of the display screen module 01, and making it easier to install and maintain.

[0068] In some embodiments, the first connecting portion 32 may include a first portion 321 and a second portion 322 . The first portion 321 is connected between the support member 4 and the screen structure 1 . The second portion 322 is connected to a side of the first portion 321 facing the screen structure 1 and surrounds the screen structure 1 .

[0069] The first portion 321 can be used to position and connect the first connection portion 32 to prevent displacement of the first connection portion 32 . The second portion 322 surrounds the screen structure 1 to form an exterior component of the display screen module 01 and protect the screen structure 1 .

[0070] In some embodiments, the display screen module 01 further includes an adhesive member 5 , which is connected between the first portion 321 and the screen structure 1 .

[0071] The first portion 321 and the screen structure 1 are connected by the adhesive 5 , and no redundant connection structure is required between the middle frame 3 and the screen structure 1 , which can simplify the structure of the components and make the installation of the display screen module 01 easier.

[0072] In some embodiments, the adhesive 5 comprises hot melt adhesive. Hot melt adhesive has good compatibility and strong adhesion to a variety of materials, including metal, glass, and plastic. Hot melt adhesive also offers fast connection speeds, high connection strength, and is less susceptible to temperature and humidity effects after connection, ensuring long-term stability of the connection quality. Therefore, using hot melt adhesive as the adhesive 5 can ensure connection reliability of the screen structure 1 and improve product yield.

[0073] Since the hot melt adhesive has a high melting temperature, if the melting point of the middle frame 3 is low, the middle frame 3 will be easily melted or deformed when the hot melt adhesive is applied to the surface of the first portion 321 .

[0074] In the prior art, cast aluminum can be used as a dispensing station on the surface of the first portion 321. However, since the cast aluminum and the first portion 321 need to be connected via a connecting structure, when applying hot melt adhesive, the hot melt adhesive may leak through the connecting gap between the cast aluminum and the first portion 321 and onto the first portion 321. To achieve the required connection strength and connection range, the surface area of the hot melt adhesive coating and the amount of hot melt adhesive must be increased. This will increase the distance from the edge of the screen structure 1 to the edge of the frame of the display module 01. The increased amount of hot melt adhesive will also increase the weight, which is not conducive to the lightweight and thin design of the display screen.

[0075] Therefore, in some embodiments, the material of the middle frame 3 may include a heat-resistant material. For example, the middle frame 3 may be made of polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), thermoplastic polyurethane (TPU), or the like.

[0076] In this way, the hot melt adhesive can be directly applied to the surface of the first part 321, and the size of the screen structure 1 exceeding the light guide structure 2 can be equal to the size of the first part 321 exceeding the second part 322. There is no need to set the additional coating size of the hot melt adhesive, thereby reducing the size of the black border of the screen.

[0077] It should be noted that since the light transmitted by the light-guiding structure 2 cannot pass through the middle frame 3 to the screen structure 1, and the light-blocking portion 31 of the middle frame is arranged between the light-guiding structure 2 and the screen structure 1, the first portion 321 is arranged between the support member 4 and the screen structure 1, and the second portion 322 is arranged around the screen structure 1, therefore, on the screen surface of the display screen, the area that displays optical information through the light-transmitting channel of the middle frame 3 is the display area, the light-blocking portion 31 and the first portion 321 are located below the screen structure 1, and are not transparent and are displayed as black edges, and the second portion 322 surrounds the screen structure 1 to form at least part of the frame. Therefore, there is no need to set the additional coating size of the hot melt adhesive, and the size of the light-blocking portion 31 and the first portion 321 along the plane of the screen structure 1 can be reduced, thereby reducing the size of the black edge of the screen.

[0078] In this way, the size of the black border of the screen is reduced, and the overall size of the middle frame 3 can also be reduced, thereby reducing the frame size of the display screen module 01.

[0079] In some other embodiments, the middle frame 3 may also be a sheet metal part or a metal casting, etc. For example, the material of the middle frame 3 may be aluminum alloy, stainless steel, aluminum oxide or nickel-chromium plated metal, etc.

[0080] In this way, the reliability of the middle frame 3 can be enhanced, and the middle frame 3 can be prevented from being deformed during installation or use.

[0081] In some embodiments, the screen structure 1 may include a glass cover plate 11 and a touch panel 12 . The touch panel 12 is connected to a side of the glass cover plate 11 facing the light guide structure 2 .

[0082] The light guide structure 2 can transmit the light source to the screen structure 1. By setting the touch panel 12, human-computer interaction of the display screen can be realized, and the convenience of the display screen module 01 is increased. A glass cover plate 11 is set on the side of the touch panel 12 away from the light guide structure 2, that is, a glass cover plate 11 is set on the outside of the display screen module 01, which can protect the surface of the display screen module 01. The glass cover plate 11 has good light transmittance, making the screen information clearer.

[0083] In some embodiments, the glass cover plate 11 is connected to the first portion 321. By connecting the glass cover plate 11 to the first portion 321, the glass cover plate 11 can be connected to the middle frame 3, thereby protecting the screen structure 1 and light guide structure 2 disposed between the glass cover plate 11 and the support member 4. Furthermore, since at least a portion of the middle frame 3 is connected between the screen structure 1 and the light guide structure 2, and the middle frame 3 can be connected to the support member 4, the glass cover plate 11 connected to the first portion 321 can secure the components between the glass cover plate 11 and the middle frame 3, preventing displacement during production, transportation, and use.

[0084] In addition, in some embodiments, an upper polarizer and a lower polarizer 14 are respectively provided on both sides of the touch panel 12. The upper polarizer 13 is provided on the side of the touch panel 12 close to the glass cover plate 11, and the lower polarizer 14 is provided on the side of the touch panel 12 away from the glass cover plate 11. The lower polarizer 14 can be used to convert the light beam generated by the backlight module into polarized light in a single direction, and the upper polarizer 13 is used to analyze the polarized light modulated by the liquid crystal, generating light and dark contrast through orthogonal polarization directions, thereby producing a display image.

[0085] In some embodiments, an optically transparent adhesive 15 may be filled between the glass cover 11 and the upper polarizer 13 to stably connect the upper polarizer 13 to the glass cover 11. The optically transparent adhesive 15 may be stable and highly transparent, allowing for precise light transmission, reducing scattering losses, and ensuring image clarity.

[0086] Please continue to refer to Figure 3 In some embodiments of the present application, the surface of the second portion 322 facing away from the first portion 321 is the first surface 3221 , and the distance between the first surface 3221 and the surface of the glass cover 11 facing the light guide structure 2 is less than or equal to the thickness of the glass cover 11 .

[0087] When the distance between the first surface 3221 and the surface of the glass cover plate 11 facing the light guide structure 2 is less than the thickness of the glass cover plate 11, the outer surface of the glass cover plate 11 protrudes beyond the first surface 3221 of the second portion 322. When the distance between the first surface 3221 and the surface of the glass cover plate 11 facing the light guide structure 2 is equal to the thickness of the glass cover plate 11, the outer surface of the glass cover plate 11 is flush with the first surface 3221. In this case, the outer frame of the display module 01 can be made thinner and lighter, avoiding the increase in the size of the display screen due to the larger size of the second portion 322.

[0088] In some embodiments, the first portion 321 is provided with a first connection structure, the support member 4 is provided with a second connection structure, and the first connection structure is connected to the second connection structure.

[0089] By connecting the first connecting structure and the second connecting structure, the middle frame 3 and the support member 4 can be connected, thereby stabilizing the structure of the middle frame 3 and enhancing the reliability of the display screen module 01.

[0090] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of another display screen module 01 provided in an embodiment of the present application. In one possible structural design, the first connecting structure and the second connecting structure can be adhesive, and the middle frame 3 and the support member 4 can be connected by adhesive bonding. For example, the middle frame 3 and the support member 4 can be fixed by glue or double-sided tape.

[0091] In another possible structural design, the first connecting structure and the second connecting structure may be a slot and a buckle, and the middle frame 3 and the support member 4 are connected by snapping.

[0092] In some other possible structural designs, the middle frame 3 and the support member 4 may also be connected by welding or riveting.

[0093] Please continue to refer to Figure 3 In some embodiments, one of the first connection structure and the second connection structure is a snap-fit groove 323 , and the other is a snap-fit protrusion 421 , and the snap-fit protrusion 421 is snap-fitted into the snap-fit groove 323 .

[0094] In this way, through the connection between the snap-fit groove 323 and the snap-fit protrusion 421, the middle frame 3 can be stably connected to the support 4, thereby positioning and pressing the screen structure 1 and the light-guiding structure 2, preventing displacement during production and transportation, and improving the reliability of the display screen assembly.

[0095] In some embodiments, the engaging groove 323 may include a first groove portion 323a and a second groove portion 323b. The first groove portion 323a is recessed along a first direction, which is consistent with the arrangement direction of the screen structure 1 and the light guide structure 2. The second groove portion 323b is recessed along a second direction perpendicular to the first direction from the inner wall surface of the first groove portion 323a. The engaging protrusion 421 may include a first protrusion portion 421a and a second protrusion portion 421b. The first protrusion portion 421a is located in the first groove portion 323a, and the second protrusion portion 421b is located in the second groove portion 323b.

[0096] Since the first groove portion 323a is recessed along the first direction and the second groove portion 323b is recessed along the second direction, the first direction is perpendicular to the second direction. In this way, the first groove portion 323a is perpendicular to the second groove portion 323b, and the first protrusion portion 421a of the snap-fitting protrusion 421 is provided in the first groove portion 323a, and the second protrusion portion 421b is provided in the second groove portion 323b. Then the first protrusion portion 421a and the second protrusion portion 421b are perpendicular. In this way, the connection between the second protrusion portion 421b and the second groove portion 323b can limit the first protrusion portion 421a, thereby reducing the looseness between the snap-fitting groove 323 and the snap-fitting protrusion 421.

[0097] In order to facilitate the second protrusion 421b to smoothly pass through the first groove portion 323a and enter the second groove portion 323b for fixation, in some embodiments, the inner surface of the snap-fitting groove 323 may include a first guide surface 3233, and the first guide surface 3233 is used to guide the snap-fitting protrusion 421 to be snapped into the snap-fitting groove 323; and / or, the snap-fitting protrusion 421 is provided with a second guide surface 4213, and the second guide surface 4213 is used to guide the snap-fitting protrusion 421 to be snapped into the snap-fitting groove 323.

[0098] In this way, when the engaging groove 323 and the engaging protrusion 421 are engaged, the engaging protrusion 421 can slide along the first guide surface 3233 and the second guide surface 4213 toward the inside of the engaging groove 323, making the connection between the engaging groove 323 and the engaging protrusion 421 smoother.

[0099] For details, please refer to Figure 3 and Figure 5 , Figure 5 for Figure 3 The enlarged partial view of the display screen module 01 shown in FIG. In some embodiments, the middle frame 3 is provided with a snap-in groove 323, and the support member 4 is provided with a snap-in protrusion 421. The middle frame 3 includes a first wall 3231 and a second wall 3232 connected to each other. The first wall 3231 is the inner wall of the snap-in groove 323. The first guide surface 3233 includes a first end and a second end. The first end is located on the first wall 3231 and is located away from the second wall 3232. The second end is located on the second wall 3232 and is located away from the first wall 3231. This forms a connecting surface between the first wall 3231 and the second wall 3232. This connecting surface can smooth the connection between the first wall 3231 and the second wall 3232 and guide the movement of the snap-in protrusion 421. For example, the first guide surface 3233 can be a first guiding slope or a first guiding arc.

[0100] Please continue to refer to Figure 3 and Figure 5 In some embodiments, the second protrusion 421b may include a third wall 4211 and a fourth wall 4212 connected to each other, and the second guide surface 4213 may include a third end and a fourth end, wherein the third end is located on the third wall 4211 and away from the fourth wall 4212, and the fourth end is located on the fourth wall 4212 and away from the third wall 4211. In this way, a connecting surface may be formed between the third wall 4211 and the fourth wall 4212, and the connecting surface may make the connection between the third wall 4211 and the fourth wall 4212 smoother, thereby guiding the engaging protrusion 421 to smoothly enter the engaging groove 323. Exemplarily, the second guide surface 4213 may be a second guiding inclined surface or a second guiding arc surface.

[0101] In some embodiments, the support member 4 includes a supporting portion 41 and a second connecting portion 42. The supporting portion 41 is arranged on the side of the light-guiding structure 2 facing away from the screen structure 1. The second connecting portion 42 is connected to the side of the supporting portion 41 facing the light-guiding structure 2 and surrounds the light-guiding structure 2. The second connecting portion 42 is connected to the middle frame 3.

[0102] The support member 4 can be a metal die-casting and provides a sturdy metal frame for the display module 01 to support the overall structure of the display module 01. The support member 4 can include a supporting portion 41 and a second connecting portion 42. The supporting portion 41 is located on the side of the light guide structure 2 facing away from the screen structure 1, that is, at the bottom of the display module 01. The supporting portion 41 can provide support for the display module 01. The second connecting portion 42 is connected to the side of the supporting portion 41 facing the light guide structure 2 and is disposed around the light guide structure 2. The second connecting portion 42 can form the outer frame of the display module 01 and protect the light guide structure 2.

[0103] In some embodiments, the outer surface of the middle frame 3 is flush with the outer surface of the second connection portion 42. In this way, the outer surfaces of the middle frame 3 and the second connection portion 42 can form a complete plane to constitute the outer surface of the display module 01.

[0104] The middle frame 3 and support member 4 can be made of different materials and surface-treated separately to achieve different colors and surface characteristics, thereby satisfying the user's varying appearance requirements. As mentioned above, the middle frame 3 can be made of plastic, sheet metal, or metal casting. The support member 4 can also be made of plastic, sheet metal, or metal casting. This is not further limited in this application; the selection can be based on the specific requirements of the display module 01.

[0105] For example, the middle frame 3 can be made of plastic, and the support member 4 can be made of alloy die-casting. Each of the middle frame 3 and support member 4 can be treated separately. This application does not limit the color or surface treatment of the middle frame 3 and support member 4. For example, spraying, printing, anodizing, and other processes can be used for surface treatment. Since both surface treatment technologies are mature and easy to operate, they can reduce production costs and improve product yield.

[0106] When the middle frame 3 is a plastic part and the support member 4 is an alloy die-casting part, the middle frame 3 and the support member 4 can be connected by a snap-fit method, such as Figure 3 As shown, the middle frame 3 and the support member 4 can also be connected by glue point, such as Figure 6 shown.

[0107] For example, Figure 7 As shown, Figure 7 This is a structural diagram of another display screen module 01 provided in an embodiment of the present application. The middle frame 3 can be made of sheet metal, and the support member 4 can be made of die-casting. The middle frame 3 and the support member 4 can be fixedly connected by gluing.

[0108] In some embodiments, the light guide structure 2 may include a light guide plate 25 , which may convert a linear light source (eg, a light source emitted by an LED) into a surface light source, thereby guiding the light to diffuse evenly.

[0109] In some embodiments, the light guide structure 2 may further include a reflective film 24, which is disposed on a side of the light guide plate 25 away from the screen structure 1. The reflective film 24 can recycle light leaking from the bottom of the light guide plate 25 and reflect it back to the light source path, thereby improving light utilization.

[0110] In some embodiments, the light guide structure 2 may further include a diffusion film 23, which is disposed on the side of the light guide plate 25 close to the screen structure 1. The diffusion film 23 may refract and scatter the light output by the light guide plate 25, eliminate hot spots, form a uniform surface light source, and increase the light emission angle, thereby improving the side view brightness and color performance.

[0111] In some embodiments, the light guide structure 2 may further include a brightness enhancement film 22 and a dual brightness enhancement film 21. Both the brightness enhancement film 22 and the dual brightness enhancement film 21 are used to enhance display brightness without increasing power consumption. The brightness enhancement film 22 is disposed on the side of the diffusion film 23 close to the screen structure 1, and the dual brightness enhancement film 21 is disposed on the side of the brightness enhancement film 22 close to the screen structure 1. The brightness enhancement film 22 may be a prism that can converge scattered light, improve light extraction efficiency, and optimize viewing angles. The dual brightness enhancement film 21 may be a DBEF that has a bidirectional electronic filtering effect (Double Brightness Enhancing Film), which recycles scattered light and converts it into an effective light source to enhance brightness.

[0112] In some embodiments, a gap is provided between the light blocking portion 31 and the light guiding structure 2. Since the membrane in the light guiding structure 2 can be made of a flexible material, providing a gap between the light blocking portion 31 and the light guiding structure 2 can prevent the light blocking portion 31 from squeezing the light guiding structure 2 and causing damage to the light guiding structure 2.

[0113] In some embodiments, the display screen module 01 may further include a flexible material disposed between the light shielding portion 31 and the light guide structure 2. This flexible material can form a buffer between the light shielding portion 31 and the light guide structure 2, thereby preventing the light shielding portion 31 and the light guide structure 2 from being directly connected, thereby preventing the light guide structure 2 from being crushed due to bumps during transportation or use.

[0114] Please continue to refer to Figure 2 In some embodiments of the present application, the display screen device 300 further includes a driving board 02 , which is connected to the side of the support member 4 facing away from the screen structure 1 and is electrically connected to the screen structure 1 and the light guide structure 2 .

[0115] The driver board 02 serves as the control unit of the display screen module 01. It can be electrically connected to the screen structure 1 and the light guide structure 2 in the display screen module 01, thereby transmitting display signals and control instructions to the display screen module 01. For example, by being electrically connected to the touch panel 12, the touch response of the display screen can be achieved; by being electrically connected to the upper polarizer 13 and the lower polarizer 14, the optical properties of the polarizer can be adjusted to optimize the display contrast; by being electrically connected to the light guide plate 25, the display brightness can be adjusted.

[0116] Connecting the driving board 02 to the side of the support member 4 facing away from the screen structure 1 can facilitate the connection between the driving board 02 and the screen structure 1 and the light guide structure 2 without causing interference to the displayed content.

[0117] In a possible structural design, the drive plate 02 can be connected to the support member 4 by bolts, so as to facilitate the disassembly, assembly and maintenance of the drive plate 02 .

[0118] In some embodiments, the display screen device 300 may further include a fixing bracket 03 , which is connected to a side of the support member 4 facing away from the screen structure 1 , and the driving board 02 is disposed between the fixing bracket 03 and the support member 4 .

[0119] The fixing bracket 03 can connect the display screen module 01 to the display carrier and fix the display screen device 300, making it easy for the driver and passengers to view and use it. In a possible structural design, the fixing bracket 03 and the support member 4 can also be connected by bolts to facilitate the disassembly and maintenance of the multi-display module.

[0120] In the description of the embodiments of the present application, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0121] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
