Detailed Implementation

[0044] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0045] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0046] In the context of the rapid evolution of intelligent vehicle technology, innovation in vehicle control, entertainment systems, and display interfaces has become a key driving force for the development of the automotive industry. Traditional car keys mostly use purely mechanical structures or are equipped with basic liquid crystal displays (LCDs). The screen-to-body ratio of these products is only up to 80%, leaving considerable room for improvement. Moreover, the display module includes, in sequence, a cover layer, a transparent adhesive layer, a touch layer, a transparent adhesive layer, a polarizer, a substrate, a color filter, a liquid crystal layer, a liquid crystal control layer, a substrate, a polarizer, a backlight layer, an adhesive backing layer, and a support layer, leaving considerable room for improvement in the thickness of the display module.

[0047] In contrast, Organic Light-Emitting Diode (OLED) display technology, especially the integration of flexible OLEDs, can significantly improve the overall performance and user experience of car keys. OLEDs, with their unique self-emissive properties, do not require a backlight, achieving better contrast, color saturation, and a wider viewing angle, while also reducing energy consumption. The thin and flexible form factor of flexible OLEDs allows for unprecedented design flexibility, easily adapting to various complex curved surfaces, bringing higher integration and aesthetics to key designs, aligning with the trend of lightweight and fashionable smart wearable devices. This technological transformation not only responds to the trend of comprehensive penetration of in-vehicle intelligence but also brings a breakthrough direction to the design concept of intelligent in-vehicle displays.

[0048] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of the present disclosure. Figure 2 This is a top view schematic diagram of a display module provided in an embodiment of the present disclosure. The first aspect of the present disclosure provides a display module including a display panel 10, a support layer 21, a first flexible circuit board 31, and a first connecting component 40. The support layer 21 is disposed on the side of the display panel 10 opposite to the display side. The bonding end of the first flexible circuit board 31 is electrically connected to the display panel 10, and the connecting end of the first flexible circuit board 31 is disposed on the side of the support layer 21 opposite to the display panel 10 by bending. The first connecting component 40 is fixed to the side of the support layer 21 opposite to the display panel 10. The first connecting component 40 is adapted to be detachably connected to one of a device or a wearable adapter component, including an electrical device or a vehicle-mounted device. The orthographic projection of the first connecting component 40 on the support layer 21 does not overlap with the orthographic projection of the connecting end of the first flexible circuit board 31 on the support layer 21.

[0049] In the above embodiments, the display module includes a display panel 10, a support layer 21, a first flexible circuit board 31, and a first connecting component 40. The support layer 21 is disposed on the side of the display panel 10 away from the display side, and the first connecting component 40 is fixed to the side of the support layer 21 away from the display panel 10. The first connecting component 40 is adapted to be detachably connected to one of a device or a wearable adapter component. The device includes a device or a vehicle-mounted device. By adding the first connecting component, the display module can be detachably connected to the device or the wearable adapter component, improving the convenience of display screen integration. Moreover, the bonding end of the first flexible circuit board 31 is electrically connected to the display panel 10. By bending the connecting end of the first flexible circuit board 31 and placing it on the side of the support layer 21 away from the display panel 10, although the connecting end of the first flexible circuit board 31 and the first connecting component 40 are located on the same side of the support layer 21, the orthographic projection of the first connecting component 40 on the support layer 21 does not overlap with the orthographic projection of the connecting end of the first flexible circuit board 31 on the support layer 21. Therefore, the added first connecting component 40 will not affect the normal display of the display screen.

[0050] The first flexible circuit board 31 can be a flexible printed circuit (FPC), a chip-on-flex (COF) film, or a main flexible printed circuit (MFPC). FPCs are thin, light, and flexible, suitable for products with limited space or requiring bending. COF involves directly attaching integrated circuit chips onto a thin film, which facilitates product miniaturization and efficient interconnection.

[0051] Electrical appliances may include refrigerators, washing machines, air conditioners, and televisions, while vehicle-mounted devices may include steering wheels, dashboards, and rearview mirrors.

[0052] The first connecting component 40 may include one of a magnetic element, a snap-fit ​​element, a plug-in element, or a clamp element, and can be adapted to different devices or wearable adapter components. For example, if the first connecting component 40 includes a magnetic element, the display module can automatically attach to electrical appliances such as refrigerators, washing machines, and water heaters. Alternatively, if the first connecting component 40 includes a snap-fit ​​element or a clamp element, the display module can be fixed to a vehicle-mounted device such as a steering wheel, hung on a rearview mirror, or installed in a wearable adapter component. Furthermore, if the first connecting component 40 includes a plug-in element, the display module can be plugged into a vehicle-mounted device such as a dashboard or steering wheel, or into an electrical appliance such as a television.

[0053] The first connecting component 40 can be made of metal, silicone, or other materials.

[0054] In practical applications, the display module can be unlocked via a button on the outer casing, a fingerprint sensor on the display panel 10, or other methods. The display module can also be locked when not locked to prevent accidental touches.

[0055] For example, the outer contour of the display module can be square (e.g., Figure 3 As shown, Figure 3 (This is a schematic diagram of another display module provided in an embodiment of the present disclosure), and it can also be circular (e.g., Figure 4 As shown, Figure 4 (This is a schematic diagram of the structure of another display module provided in the embodiments of this disclosure), and it can also be in other shapes.

[0056] In some instances, the display panel 10 may include a flexible display panel that is bent or flexed to fit the shape of a device or wearable adapter component.

[0057] For example, see Figure 1 , Figure 3 and Figure 4 The display panel 10 may include a display layer 11 and a substrate layer 12. The substrate layer 10 is connected to the support layer 21 via a double-sided adhesive layer 13. The display layer 11 may include display units and matching drive control circuitry.

[0058] The first flexible circuit board 31 can also be connected to the support layer 21 via the double-sided adhesive layer 13.

[0059] Double-sided adhesive layer 13 can be a thermally conductive adhesive.

[0060] For example, the support layer 21 can be a metal plate. The support layer 21 includes a patterned structure, which includes multiple grooves and / or multiple cutouts. The openings of the grooves face the side of the support layer 21 away from the display panel 10, and the cutouts extend through the support layer 21. By forming a patterned structure with multiple grooves and / or multiple cutouts on the metal plate, the support layer 21 is flexible and can be bent or flexed to fit the shape of the device or wearable adapter component, facilitating the fixing of the display module to the device or wearable adapter component.

[0061] In some embodiments, see Figure 2 The support layer 21 includes a first region 211 and a second region 212. The orthographic projection of the first connecting component 40 onto the support layer 21 falls into the first region 211, and the orthographic projection of the first flexible circuit board 31 onto the support layer 21 falls into the second region 212. The density of the patterned structure in the first region 211 is less than the density of the patterned structure in the second region 212.

[0062] For example, the graphic structure of the first region 211 includes multiple grooves, and the graphic structure of the second region 212 includes multiple grooves and / or multiple cutouts.

[0063] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The display module may also include a cover plate 22, which is disposed on the side of the display panel 10 away from the support layer 21.

[0064] For example, the plane on which the display side of the display panel is located is the first plane, and the orthographic projections of the display panel 10, the support layer 21, the first flexible circuit board 31 and the first connecting component 40 on the first plane are all located within the orthographic projection of the cover plate 22 on the first plane.

[0065] In practical applications, the cover plate 22 can be a hard and transparent protective layer covering the display side of the display panel 10. The material of the cover plate 22 can be glass or plastic, which can resist scratches and impacts and meet the special needs of car keys in practical application scenarios, such as high weather resistance for long-term outdoor use and high scratch resistance under frequent operation.

[0066] For example, see Figure 1 The cover plate 22 may have an ink area 220 on the side near the display panel 10, and the ink area 200 is located at the edge of the cover plate 22. The ink area 220 is coated with special ink on the surface of the cover plate 22, which can enhance the functions of wear resistance and anti-glare, and can also be used to print touch circuits, brand logos, etc.

[0067] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The display module may also include a biosensor 51, which is disposed between the cover plate 22 and the support layer 21. The biosensor 51 is used to sense biological characteristic parameters of an organism, such as body temperature, heart rate, blood pressure, and blood saturation. By adding the biosensor 51, biological characteristic parameters can be provided for monitoring the driver's health status, which is beneficial for setting up a fatigue driving warning system, monitoring and analyzing the driver's physiological data in real time, realizing all-weather health management, and improving driving safety.

[0068] In one possible embodiment, the orthographic projection of the biosensor 51 on the cover plate 22 does not overlap with the orthographic projection of the display panel 10 on the cover plate 21.

[0069] For example, the orthographic projection of the biosensor 51 on the cover plate 22 at least partially surrounds the orthographic projection of the display panel 10 on the cover plate 22.

[0070] In another possible embodiment, the orthographic projection of the biosensor 51 on the cover plate 22 does not overlap with the orthographic projection of the display area of ​​the display panel 10 on the cover plate 22.

[0071] For example, the orthographic projection of the biosensor 51 on the cover plate 22 at least partially surrounds the orthographic projection of the display area of ​​the display panel 10 on the cover plate 22.

[0072] In the two possible embodiments described above, see [reference] Figure 2 The orthographic projection of the biosensor 51 on the cover plate 22 does not overlap with the orthographic projection of the first flexible circuit board 31 on the cover plate 22.

[0073] For example, see Figure 2 The biosensor 51 can be arranged around the edge of the cover plate 22 and has an opening, and the connection end of the first flexible circuit board 31 passes through the opening of the biosensor 51.

[0074] For example, see Figure 2 The orthographic projection of the biosensor 51 on the cover plate 22 does not overlap with the orthographic projection of the first connecting component 40 on the cover plate 22.

[0075] In some embodiments, see Figure 5 , Figure 5 This is a schematic diagram of the distribution area of ​​a biosensor provided in an embodiment of this disclosure. The non-overlapping area of ​​the orthographic projection of the biosensor 51 on the cover plate 22 and the orthographic projection of the support layer 21 on the cover plate 22 is a first area S. The ratio of the first area S to the area of ​​the support layer 21 is less than or equal to 10%. Most of the area of ​​the biosensor 51 overlaps with the orthographic projection of the support layer 21 on the cover plate 22, which is beneficial for fixing the biosensor 51 between the support layer 21 and the cover plate 22.

[0076] For example, see Figure 6 , Figure 6 This is a schematic diagram of the structure of a display module provided in an embodiment of the present disclosure. The biosensor 51 is connected to the side of the cover plate 22 near the display panel 10 via double-sided adhesive tape 511, and the biosensor 51 is connected to the side of the support layer 21 near the display panel 10 via double-sided adhesive tape 511.

[0077] In one possible embodiment, see [reference] Figure 7 , Figure 7 The following is a schematic diagram of another display module provided in an embodiment of the present disclosure. The display module may also include a barrier adhesive 512, which is connected to the biosensor 51 and the cover plate 22 respectively.

[0078] For example, see Figure 7The barrier adhesive 512 is connected to the side of the biosensor 51 away from the display panel 10 and the surface of the cover plate 22 near the biosensor 51.

[0079] In another possible embodiment, see Figure 8 , Figure 8 This is a schematic diagram of another display module provided in an embodiment of the present disclosure. The display module may further include a barrier adhesive 512, which is connected to the biosensor 51 and the support layer 21 respectively.

[0080] For example, see Figure 8 The barrier adhesive 512 is connected to the side of the biosensor 51 away from the display panel 10 and the side of the support layer 21 that is thicker than the display panel 10.

[0081] In yet another possible embodiment, see [reference] Figure 9 , Figure 9 This is a schematic diagram of another display module provided in an embodiment of the present disclosure. The display module may further include two barrier adhesives 512. One barrier adhesive 512 is connected to the biosensor 51 and the cover plate 22 respectively, and the other barrier adhesive 512 is connected to the biosensor 51 and the support layer 21 respectively.

[0082] For example, see Figure 9 One barrier adhesive 512 is connected to the side of the biosensor 51 away from the display panel 10 and the surface of the cover plate 22 close to the biosensor 51, respectively. Another barrier adhesive 512 is connected to the side of the biosensor 51 away from the display panel 10 and the thickness side of the support layer 21, respectively.

[0083] In the three possible embodiments described above, the barrier adhesive 512 can be a waterproof adhesive or a flame-retardant adhesive.

[0084] In some embodiments, see Figure 10 , Figure 10 This is a top view of a display module provided in an embodiment of the present disclosure. The display module may also include a second flexible circuit board 32. The bonding end of the second flexible circuit board 32 is electrically connected to the biosensor 51. The connecting end of the second flexible circuit board 51 is disposed on the side of the support layer 21 away from the display panel 10 by bending.

[0085] For example, see Figure 10 The orthographic projection of the second flexible circuit board 32 on the support layer 21 does not overlap with the orthographic projection of the first connecting component 40 on the support layer 21.

[0086] For example, see Figure 10 The display module may include multiple second flexible circuit boards 32, each of which is located on a different side of the support layer 21.

[0087] In one possible embodiment, the first flexible circuit board 31 includes a driver chip, and the second flexible circuit board 32 is electrically connected to the first flexible circuit board 31.

[0088] In another possible embodiment, the display panel 10 includes a display driver chip, which is electrically connected to the first flexible circuit board 31, and the second flexible circuit board 32 is electrically connected to the first flexible circuit board 31.

[0089] In yet another possible embodiment, see [reference] Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of another display module provided in an embodiment of the present disclosure. Figure 12 This is a top view schematic diagram of another display module provided in an embodiment of the present disclosure. The display module may further include a printed circuit board 33, which is disposed on the side of the support layer 21 away from the display panel 10. Electronic components 330 are disposed on the side of the printed circuit board 33 away from the support layer 21. The first flexible circuit board 31 and the second flexible circuit board 32 are both electrically connected to the printed circuit board 33.

[0090] For example, see Figure 11 The first flexible circuit board 31 can be connected to the display panel 10 and the printed circuit board 33 respectively via anisotropic conductive adhesive 62. The anisotropic conductive adhesive 62 conducts electricity only in the vertical direction and is insulated in the horizontal direction, which is beneficial for precise thermo-press bonding processes.

[0091] For example, see Figure 12 The orthographic projection of the printed circuit board 33 on the support layer 21 does not overlap with the orthographic projection of the first connecting component 40 on the support layer 21.

[0092] For example, see Figure 11 In the first direction, the height of the first connecting component 40 is greater than the maximum height of the printed circuit board 33, and the first direction is the direction perpendicular to the plane where the display panel 10 is located.

[0093] For example, the printed circuit board 23 can be a control motherboard or a flexible circuit board. When the printed circuit board is a flexible circuit board, the control motherboard can be located inside the device.

[0094] In some embodiments, see Figure 13 , Figure 13 This is a schematic diagram of another display module provided in an embodiment of the present disclosure. The display module may further include a functional film layer 52, which is disposed on the side of the cover plate 22 away from the display panel 10. The area of ​​the functional film layer 52 is less than or equal to the area of ​​the cover plate 22.

[0095] For example, the functional film layer can be an AMF antibacterial film, or other functional film layers, such as fingerprint film, anti-scratch film, etc. AMF antibacterial film is a special thin film that covers the surface of the display module. It contains antibacterial substances such as silver ions, which can effectively inhibit bacterial growth, keep the screen surface hygienic, and at the same time maintain light transmittance and touch sensitivity, providing users with a safe and clean user experience.

[0096] For example, see Figure 14 , Figure 14 This is a partial structural schematic diagram of another display module provided in an embodiment of the present disclosure. The overlapping area of ​​the orthographic projection of the functional film layer 52 on the cover plate 22 and the orthographic projection of the biosensor 51 on the cover plate 22 is the second area, and the area of ​​the orthographic projection of the biosensor 51 on the cover plate 22 is the third area. The ratio of the second area to the third area is greater than or equal to 95%.

[0097] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The display module may also include a polarizer 53, which is disposed between the display panel 10 and the cover plate 22. The polarizer can filter out light with a specific polarization direction, enabling the display module to present a clear black and white contrast.

[0103] In yet another possible embodiment, see [reference] Figure 18 , Figure 18 This is a partial structural diagram of another display module provided in an embodiment of the present disclosure. The display panel 10 may further include a third touch layer, which is located on the display side of the display panel 10, that is, the display layer 11 is disposed between the third touch layer and the substrate layer 12.

[0104] In the above embodiments, the touch layer is located inside the display panel 10, with a small overall thickness and low implementation cost.

[0105] In the above three possible embodiments, the first touch layer, the second touch layer 54, and the third touch layer can be provided with multiple touch sensors, or at least two touch electrode layers can be provided, with multiple touch electrodes provided in each touch electrode layer.

[0106] For example, see Figure 19 , Figure 19 This is a partial structural diagram of another display module provided in an embodiment of the present disclosure. The display module may further include two touch electrode layers, each of which is disposed on a touch substrate layer. The touch electrode layer near the cover plate 22 is connected to the cover plate 22 via an OCA, and the touch substrate layer disposed on the touch electrode layer near the polarizer 53 is connected to the polarizer 53 via an OCA.

[0107] In one possible embodiment, the display module may further include a Near Field Communication (NFC) component, which is suitable for external communication interaction.

[0108] See Figure 1 In another possible embodiment, the display module may further include an electrical connector 55, one end of which is electrically connected to the display panel 10 or the first flexible circuit board 31, and the other end of which is used to connect to a device or wearable connection component. The reserved electrical connector facilitates electrical connection to the device or wearable connection component.

[0109] In another possible embodiment, the display module may further include a near-field communication component and an electrical connector 55. One end of the electrical connector 55 is electrically connected to the display panel 10 or the first flexible circuit board 31, and the other end of the electrical connector 55 is used to connect to a device or wearable connection component. In this way, the electrical connector 55 can serve as a backup interface to ensure the normal use of the display module.

[0110] See Figure 20 , Figure 20 This is a schematic diagram of the structure of a display device provided in an embodiment of the present disclosure. In a second aspect of the present disclosure, a display device is provided, which includes a control motherboard 100 and a display module 200 as provided in any embodiment of the first aspect.

The first connecting component is adapted to be detachably connected to one of the equipment or wearable adapter components. The equipment includes a device or an in-vehicle device. By adding the first connecting component, the display module can be detachably connected to the equipment or wearable adapter component, improving the convenience of display screen integration. Moreover, the bonding end of the first flexible circuit board is electrically connected to the display panel. By bending the connecting end of the first flexible circuit board and disposing it on the side of the support layer away from the display panel, although the connecting end of the first flexible circuit board and the first connecting component are located on the same side of the support layer, the orthographic projection of the first connecting component on the support layer and the orthographic projection of the connecting end of the first flexible circuit board on the support layer do not overlap. Therefore, the added first connecting component will not affect the normal display of the display screen.

[0114] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
