Description

Technical Field

[0001] This utility model belongs to the field of automotive intelligent front face technology, specifically relating to an intelligent front face with electronic ink luminescent display. Background Technology

[0002] Illuminated grilles are a combination of traditional air intake grilles and lighting modules. Traditional grilles primarily provide air to the engine, facilitating oxygen supply and heat dissipation. With the development of electrification, the air intake grille's role has shifted to decorative elements. Consumers demand not only aesthetic appeal and personalization but also a degree of illumination functionality. Therefore, illuminated grilles have emerged as a trend in modern automotive design. As the market share of electric vehicles increases, illuminated grilles and bumpers are increasingly used. Each product is large, employing numerous LEDs, resulting in high power consumption and impacting the vehicle's range to some extent. However, by employing electronic ink (E-Ink) technology, the front of the car can be illuminated with low energy consumption, and different personalized lighting modes can be implemented, such as welcome greetings, flowing water effects, jumping water effects, and music show modes. Currently available exterior lighting displays use LEDs, COBs, optical fibers, light guides, and displays as light sources. Moreover, the light source modules are large, requiring more space on the back of the product for arrangement. Existing lighting displays use LED, COB, and optical fiber solutions for their light sources, resulting in a large internal space for the overall product layout on the front and lower adaptability to grilles. Furthermore, the power consumption of existing LED, COB, and optical fiber lighting technologies is relatively higher than that of electronic inks. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a smart front face with electronic ink light-emitting display that is simple in structure, low in power consumption, and has low requirements for product layout space, in light of the current state of the technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a smart front face with electronic ink light-emitting display, comprising a front face body, characterized in that an electronic ink light-emitting display module is installed on the front face body, the electronic ink light-emitting display module comprising an electronic ink layer, an upper electrode layer and a lower electrode layer, the upper electrode layer and the lower electrode layer being respectively arranged on the front and back of the electronic ink layer, positive and negative lines being led out from the upper electrode layer and the lower electrode layer and electrically connected to an internal control module, the control module controlling the electronic ink light-emitting display module to display different patterns on the smart front face.

[0005] This patent primarily utilizes electronic ink (E-ink) technology. Since E-ink technology projects natural light onto a film layer and displays brightness through reflection, it eliminates the need for a backlight and replaces traditional lighting methods with light sources. Furthermore, the upper and lower electrode layers can form a conductive circuit with the control module during use. The electronic ink layer in this patent is mainly composed of numerous microcapsules, each only the size of a human hair. The black and white spheres within the microcapsules are pigment particles with different charges. Initially, these pigment particles are suspended within the microcapsules. The electronic control module controls different voltages via a driver IC chip. Applying different voltages through the electrode layers pushes the corresponding pigment particles to the top, causing the microcapsules to display different colors. These different colored microcapsules form various texts and patterns. The power consumption is only about 8% of that of a light source, achieving ultra-low power consumption. Therefore, when combined with the front panel, there is no longer any range anxiety caused by power consumption issues related to light emission.

[0006] In the aforementioned smart front panel with an electronic ink luminescent display, a conductive ink pattern layer is arranged between the electronic ink layer and the lower electrode layer. This conductive ink pattern layer allows for the printing of any pattern on the back of the electronic ink layer, resulting in a better aesthetic appearance during actual use.

[0007] In the aforementioned smart front panel with an electronic ink luminescent display, positive and negative leads from the upper and lower electrode layers are electrically connected to FPC flexible flat cables. These leads are then electrically connected to an internal control module via the FPC flexible flat cables. By applying different voltages to the leads via the FPC flexible flat cables, the electronic ink luminescent display module can display different patterns, enabling various luminous modes such as welcoming and farewell displays, flowing water effects, jumping water effects, and music show modes.

[0008] In the aforementioned smart front panel with an electronic ink luminescent display, the electronic ink luminescent display module is formed on the surface of the front panel body by insert injection molding.

[0009] As another approach, in the aforementioned smart front panel with an electronic ink luminescent display, the electronic ink luminescent display module further includes an upper protective film layer and a lower protective film layer. The upper protective film layer is disposed on the front side of the upper electrode layer, and the lower protective film layer is disposed on the back side of the lower electrode layer. Here, the upper and lower protective film layers encapsulate and protect the electronic ink layer, ensuring the reliability of the pattern display.

[0010] In the aforementioned smart front panel with an electronic ink luminescent display, an adhesive layer is further provided on the back of the lower protective film layer. The electronic ink luminescent display module is attached to the surface of the front panel body via this adhesive layer. Here, the adhesive layer can be made of OCA adhesive or OCR adhesive and directly bonded to the surface of the front panel body.

[0011] In the aforementioned smart front panel of an electronic ink luminescent display, a PUR coating is also provided on the front surface of the upper electrode layer. Here, the PUR coating serves two purposes: firstly, it replaces paint, encapsulating the electronic ink luminescent display module and preventing moisture from entering and causing the electronic ink to fail; secondly, it also blocks harmful ultraviolet rays from reaching the electronic ink layer.

[0012] In the aforementioned smart front panel with an electronic ink luminescent display, a hardened coating is also provided on the front surface of the upper electrode layer. When a plastic material is used, the hardened coating serves both a protective function and blocks harmful ultraviolet rays from reaching the electronic ink layer.

[0013] In the aforementioned smart front fascia featuring an electronic ink luminescent display, the electronic ink luminescent display module can display two colors (black and white), three colors (black and white with red), four colors (black and white with red and yellow), and multiple colors. By applying different voltages under the same mode, different colors can be displayed, meeting the needs of car owners under various operating conditions.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. Low power consumption: Electronic ink is printed on the film, and it uses natural light to project onto the film and displays the brightness through reflection. The power consumption accounts for about 8% of the light source.

[0016] 2. High adaptability: Electronic ink films can be adapted to products with different curvatures and can be directly bonded to the product surface;

[0017] 3. Small footprint: The thin e-ink luminescent display film can be used even in limited spaces. Intelligent front fascias are often used for front-end decoration, improving vehicle recognition and adding a sense of style and dynamism. Intelligent front fascias use LED beads as the light source, featuring high brightness to enhance vehicle visibility and ensure driving safety. However, they are characterized by high power consumption and require a large space. Using e-ink technology for the luminescent display eliminates the need for an LED backlight, alleviating concerns about power consumption, range anxiety, and environmental issues.

[0024] Example 1

[0025] like Figure 1 , Figure 2 as well as Figure 3 As shown, the intelligent front panel of this electronic ink luminescent display includes a front panel body 100, on which an electronic ink luminescent display module 200 is mounted. In this embodiment, the electronic ink luminescent display module 200 is formed on the surface of the front panel body 100 by insert injection molding. The electronic ink luminescent display module 200 includes an electronic ink layer 300, an upper electrode layer 400, and a lower electrode layer 500, which are respectively arranged on the front and back sides of the electronic ink layer 300. The upper electrode layer 400 and the lower electrode layer 500 lead out positive and negative wires and are electrically connected to an internal control module. The control module controls different voltages through a driver IC chip, thereby causing different patterns to be displayed on the electronic ink luminescent display module 200. A conductive ink pattern layer 1000 is arranged between the electronic ink layer 300 and the lower electrode layer 500. This conductive ink pattern layer 1000 allows for the printing of any pattern on the back of the electronic ink layer, resulting in a better appearance during actual use. Positive and negative leads from the upper electrode layer 400 and the lower electrode layer 500 are electrically connected to an FPC flexible flat cable 600. These leads are electrically connected to the internal control module via the FPC flexible flat cable 600. Different voltages can be applied to the positive and negative leads via the FPC flexible flat cable 600 to enable the electronic ink luminescent display module 200 to display different patterns, achieving different luminescent modes such as welcoming and farewell, left and right flowing water, jumping flowing water, and music show modes.

[0026] In addition, a PUR coating 700 is provided on the front side of the upper electrode layer 400. Here, the PUR coating 700 serves two purposes: firstly, it replaces paint, encapsulating the electronic ink light-emitting display module 200 and preventing moisture from entering and causing the electronic ink to fail; secondly, it can also block harmful ultraviolet rays from the electronic ink layer 300. Alternatively, a hardened coating 800 can be used instead. When plastic material is used, the hardened coating 800 serves two purposes: firstly, it provides protection, and secondly, it can block harmful ultraviolet rays from the electronic ink layer 300.

[0027] This patent primarily utilizes electronic ink (E-ink) technology. Since E-ink technology projects natural light onto a film layer and displays brightness through reflection, it eliminates the need for a backlight and replaces the traditional lighting method with a light source. Furthermore, the upper electrode layer 400 and lower electrode layer 500 can form a conductive circuit with the control module during use. The electronic ink layer 300 in this patent is mainly composed of numerous microcapsules, each only the size of a human hair. The black and white spheres within the microcapsules are pigment particles with different charges. Initially, the pigment particles are suspended within the microcapsules. The electronic control module controls different voltages via a driver IC chip. Applying different voltages through the electrode layers pushes the corresponding pigment particles to the top, causing the microcapsules to display different colors. These different colored microcapsules form various texts and patterns. The power consumption is only about 8% of that of a light source, achieving ultra-low power consumption. This eliminates range anxiety caused by power consumption when integrated with the front panel. The electronic ink light-emitting display module 200 can display black and white dual-color, black and white three-color, black and white four-color, and multi-color displays. By applying different voltages under the same mode, different colors can be displayed to meet the needs of car owners under different operating conditions.

[0028] Example 2

[0029] like Figure 4As shown, most of the structure in this embodiment is the same as in Embodiment 1. The difference is that the electronic ink light-emitting display module 200 also includes an upper protective film layer 1001 and a lower protective film layer 1002. The upper protective film layer 1001 is arranged on the front side of the upper electrode layer 400, and the lower protective film layer 1002 is arranged on the back side of the lower electrode layer 500. Here, the upper protective film layer 1001 and the lower protective film layer 1002 are used to encapsulate and protect the electronic ink layer 300, ensuring the reliability of the pattern display. In addition, an adhesive layer 900 is also provided on the back side of the lower protective film layer 1002. The electronic ink light-emitting display module 200 is attached to the surface of the front body 100 through the adhesive layer 900. Here, the adhesive layer 900 can... The upper electrode layer 300 can be directly attached to the surface of the front body 100 using OCA glue or OCR glue. Similarly, a PUR coating 700 is also provided on the front side of the upper electrode layer 400. Here, the PUR coating 700 serves two purposes: firstly, it replaces paint, encapsulating the electronic ink light-emitting display module 200 and preventing moisture from entering and causing the electronic ink to fail; secondly, it can also block ultraviolet rays that are harmful to the electronic ink layer 300. Alternatively, a hardened coating 800 can be used instead. A hardened coating 800 is also provided on the front side of the upper electrode layer 400. When plastic material is used, the hardened coating 800 serves two purposes: firstly, it provides protection, and secondly, it can block ultraviolet rays that are harmful to the electronic ink layer 300.

[0030] During manufacturing, the capsule-encapsulated electronic ink layer 300 is first coated onto a PC / PET film. Any pattern, such as the letter M, is printed on the back of the electronic ink layer. The upper electrode layer 400 is printed on the upper layer of the electronic ink layer. The conductive ink pattern layer 1000 and the lower electrode layer 500 are printed on the lower layer. The upper and lower electrodes form a conductive circuit, leading out the positive and negative electrodes.

[0031] 2: The electronic ink light-emitting display module 200 can be inserted into the body of PC or PMMA by injection molding; the outer surface is filled with PUR coating 700 by injection molding. The function of PUR coating 700 is to encapsulate the electronic ink light-emitting display module 200 assembly, prevent moisture from entering the interior and causing the electronic ink layer 300 to fail; it can also provide the electronic ink film with UV resistance and abrasion resistance to meet automotive-grade performance requirements.

[0032] 3: The positive and negative terminals can be loaded with different voltages through the FPC flexible flat cable 600 to make the electronic ink light-emitting display module 200 assembly display different patterns, and can realize different light-emitting modes such as: welcoming guests, left and right flowing water, jumping flowing water, and music show mode.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
