Description

Technical Field

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

[0002] As the market share of electric vehicles increases, all products on electric vehicles that require illumination will need electricity. Using electronic ink (E-ink) technology would allow trim pieces to display different patterns without the need for power when the electric vehicle's range is low. Taking the B-pillar panel of a car as an example, in welcome mode, the B-pillar panel dynamically illuminates with a flowing light as the owner approaches the car door; when the owner exits, the pattern on the B-pillar panel illuminates to bid farewell. When the electric vehicle is charging, different colors on the B-pillar panel can represent different charging states: such as charging start, charging in progress, charging complete, and charging failure. However, existing illuminated displays on exterior trims use LCD screens, LED strips, fiber optics, and LEDs as light sources. These light source modules are large, requiring more space on the back of the product for arrangement. Furthermore, the power consumption of these technologies is relatively high. Therefore, it is necessary to design a new type of intelligent illuminated pillar panel. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an intelligent column plate with electronic ink light emission display, which addresses the current state of the existing technology. By adopting electronic ink (E-ink) technology, electronic ink is printed on a film, and natural light is projected onto the film and displayed through reflected brightness, thereby achieving ultra-low power consumption and solving the product's layout space requirements.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a smart column plate with electronic ink light-emitting display, characterized in that it includes an outer plate, an inner plate, an electronic ink light-emitting display module and an electronic control module, a display area is provided between the outer plate and the inner plate, the electronic ink light-emitting display module is installed in the display area, the electronic ink light-emitting display module is electrically connected to the electronic control module, and the electronic control module controls the electronic ink light-emitting display module to display different patterns on the smart column plate.

[0005] As a priority, in the aforementioned smart column panel with electronic ink light emission display, the electronic ink light emission display module includes an electronic ink layer, an upper electrode layer, a lower electrode layer, an upper protective film layer, and a lower protective film layer. The upper electrode layer and the lower electrode layer are respectively arranged on the front and back sides of the electronic ink layer. The upper protective film layer is arranged on the front side of the upper electrode layer, and the lower protective film layer is arranged on the back side of the lower electrode layer.

[0006] This patent primarily utilizes electronic ink (E-ink) technology. By printing an electronic ink layer onto a film layer, the upper and lower protective films serve a sealing and protective function. Since E-ink technology projects natural light onto the film layer and displays brightness through reflection, a backlight is eliminated, replacing the traditional light-emitting method. Furthermore, the upper and lower electrode layers form a conductive circuit with the electronic control module during use. The electronic ink layer in this patent mainly consists 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-emitting source, achieving ultra-low power consumption. Therefore, when combined with a pillar plate component, range anxiety caused by power consumption issues related to light emission is eliminated.

[0007] In the aforementioned intelligent column panel with electronic ink luminescence display, the electronic control module is electrically connected to a flexible flat panel (FPC) strip. Positive and negative electrodes are led out from the upper and lower electrode layers and then electrically connected to the electronic control module via the FPC strip.

[0008] Here, the flexible flat panel cable (FPC) allows for easy connection of the positive and negative electrodes of the upper and lower electrode layers to the electronic control module. This enables the electronic control module to control different voltages via a driver IC chip, displaying different patterns after applying different voltages to the electrode layers.

[0009] As a preferred embodiment, in the aforementioned smart column panel with an electronic ink luminescent display, a conductive ink pattern layer is arranged between the electronic ink layer and the lower electrode layer, or between the lower electrode layer and the lower protective film 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 appearance during actual use.

[0010] As a preferred embodiment, in the aforementioned intelligent column panel with electronic ink luminescence display, the outer panel is made of glass, and the inner side of the outer panel is coated with a weather-resistant ink layer by printing or spraying. The upper protective film layer has a bonding surface that matches the inner side of the outer panel, and the bonding surface has an adhesive layer. The electronic ink luminescence display module is attached to the back of the weather-resistant ink layer through the adhesive layer.

[0011] When the outer panel is made of glass, a weather-resistant ink layer needs to be printed or sprayed first. The weather-resistant ink layer can shield and block ultraviolet rays that are harmful to the electronic ink layer. Then, an adhesive layer is attached to the back of the weather-resistant ink layer for installation. The adhesive layer can be OCA glue or OCR glue.

[0012] As a preferred embodiment, in the aforementioned intelligent column panel with electronic ink luminescent display, the outer panel is made of plastic, the upper protective film layer has a bonding surface that mates with the inner side of the outer panel, and an adhesive layer is provided on the bonding surface. The electronic ink luminescent display module is attached to the display area on the inner side of the outer panel through the adhesive layer.

[0013] In another embodiment, in the aforementioned smart column panel with electronic ink luminescence display, the outer panel is made of plastic, and the electronic ink luminescence display module is formed in the display area on the inner side of the outer panel by insert injection molding.

[0014] Of course, the outer panel can also be made of plastic. One way to form an electronic ink light-emitting display module is to directly form it as an insert or install it through an adhesive layer. Similarly, the adhesive layer here can be OCA adhesive or OCR adhesive.

[0015] In the aforementioned smart column panel with an electronic ink luminescent display, the outer surface of the outer panel has a hardened coating. When plastic is used, the hardened coating serves both a protective function and blocks harmful ultraviolet rays from reaching the electronic ink layer.

[0016] In the aforementioned smart column panel with an electronic ink luminescent display, the outer surface of the outer panel has a PUR layer. Here, the PUR layer serves two purposes: firstly, it replaces paint, and secondly, it blocks harmful ultraviolet rays from reaching the electronic ink layer.

[0017] In the aforementioned smart pillar panel with 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 different operating conditions.

[0018] In the aforementioned intelligent column panel for electronic ink luminescent display, a sealing cover is provided on the upper back of the display area to protect the electronic ink luminescent display module. This sealing cover is mounted on the inner panel. The sealing cover prevents moisture from entering the electronic ink luminescent display module, thus preventing product failure.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] 1. Low overall power consumption, capable of displaying black and white dual color, black and white three color, black and white four color, black and white four color, and multiple colors. Due to the elimination of the backlight, the power consumption of electronic ink accounts for a maximum of 8% of the light-emitting mode. After being combined with the column plate, there is no longer any range anxiety caused by power consumption due to light emission.

[0021] 2. Electronic ink can completely replace LCD displays, LED strips, optical fibers, LEDs, etc. with light sources. It has a wide range of applications and low requirements for product layout and structural space.

[0022] 3. The overall encapsulation features two protective films to prevent moisture from entering the electronic ink layer, which could lead to product failure. It can also integrate an ink pattern layer to display dynamic welcome patterns or charging status, making users feel at home and enhancing their driving experience. Attached Figure Description

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] In the diagram, outer panel 100; inner panel 200; electronic control module 300; display area 400; electronic ink layer 500; upper electrode layer 600; lower electrode layer 700; upper protective film layer 800; lower protective film layer 900; flexible flat cable FPC tape 1000; adhesive layer 1001; weather-resistant ink layer 1002; conductive ink pattern layer 1003; sealing cover 1004; hardened coating 1005; PUR layer 1006; butyl rubber 1007; adhesive 1008; electronic ink light-emitting display module 1009.

[0031] like Figure 1 and Figure 2As shown, this intelligent column panel with electronic ink luminescent display can be a column A, column B, or column C. In this embodiment, column B is taken as an example. It mainly includes an outer panel 100, an inner panel 200, an electronic ink luminescent display module 1009, and an electronic control module 300. The outer panel 100 and the inner panel 200 are bonded together with adhesive 1008. There is a display area 400 between the outer panel 100 and the inner panel 200. The electronic ink luminescent display module 1009 is installed in the display area 400. The electronic ink luminescent display module 1009 is mainly used to display patterns. Therefore, the inner panel 200 at the pattern display position needs to be designed with clearance to allow the electronic ink luminescent display module 1009 to be attached. For ease of control, the electronic ink luminescent display module 1009 is electrically connected to the electronic control module 300 in the display area 400 of the 9th section. The electronic control module 300 controls different voltages through a driver IC chip, thereby displaying different patterns on the electronic ink luminescent display module 1009. The electronic ink luminescent display module 1009 can display black and white dual colors, black and white three colors, black and white four colors, black and white four colors, and multiple colors. By applying different voltages in the same mode, different colors can be displayed, which can meet the needs of car owners under different working conditions. The luminescent display pattern can be a dynamic flow from top to bottom and then the overall display pattern is presented, or the display pattern can be presented directly.

[0032] Specifically, the inner panel 200 is mainly made of plastic, while the outer panel 100 can be made of plastic or glass. The following will explain the different materials of the outer panel 100.

[0033] like Figure 3 as well as Figure 4As shown, when the outer panel 100 is made of glass, the electronic ink light-emitting display module 1009 in this patent, as the core of the light-emitting display, includes an electronic ink layer 500, an upper electrode layer 600, a lower electrode layer 700, an upper protective film layer 800, and a lower protective film layer 900. The protective film layer can be made of PC / PET film. The upper electrode layer 600 and the lower electrode layer 700 are respectively arranged on the front and back sides of the electronic ink layer 500. The upper protective film layer 800 is arranged on the front side of the upper electrode layer 600, and the lower protective film layer 900 is arranged on the back side of the lower electrode layer 700. The electronic control module 300 is mounted on the inner panel 200. The sub-control module 300 is electrically connected to a flexible flat panel cable (FPC) strip 1000. Positive and negative terminals are led out from the upper electrode layer 600 and the lower electrode layer 700, and then electrically connected to the electronic control module 300 via the FPC strip 1000. The FPC strip 1000 facilitates the connection between the upper electrode layer 600 and the lower electrode layer 700 and the electronic control module 300. Thus, the electronic control module 300 internally controls different voltages via a driver IC chip. Different patterns are displayed after applying different voltages to the electrode layers. A weather-resistant ink layer 1002 is printed or sprayed on the inner side of the glass. The upper protective film layer has a connection with the inner side of the outer panel 100. The side-fitting bonding surface has an adhesive layer 1001. The electronic ink light-emitting display module 1009 is attached to the back of the weather-resistant ink layer 1002 via the adhesive layer 1001. When the outer panel 100 is made of glass, the weather-resistant ink layer 1002 needs to be printed or sprayed first. The weather-resistant ink layer 1002 can shield and block ultraviolet rays that are harmful to the electronic ink layer 500. Then, it is attached to the back of the weather-resistant ink layer 1002 via the adhesive layer 1001 for installation. Here, the adhesive layer 1001 can be OCA adhesive or OCR adhesive. As a further optimization, the electronic ink layer 500 and the lower electrode layer 700... A conductive ink pattern layer 1003 is arranged between or between the lower electrode layer 700 and the lower protective film layer 900. Here, any pattern can be printed on the back of the electronic ink layer through the conductive ink pattern layer 1003, so that the appearance effect is better in actual use. In order to protect the entire electronic ink light-emitting display module 1009, a sealing cover plate 1004 is also provided on the upper back of the display area 400 for protecting the electronic ink light-emitting display module 1009. The sealing cover plate 1004 is installed and connected to the inner plate 200. Here, the sealing cover plate 1004 can prevent moisture from entering the electronic ink light-emitting display module 1009, which would cause product failure.

[0034] like Figure 3 as well as Figure 5As shown, when the outer panel 100 is made of plastic, the electronic ink light-emitting display module 1009 also includes an electronic ink layer 500, an upper electrode layer 600, a lower electrode layer 700, an upper protective film layer 800, and a lower protective film layer 900. The upper electrode layer 600 and the lower electrode layer 700 are respectively arranged on the front and back sides of the electronic ink layer 500. The upper protective film layer 800 is arranged on the front side of the upper electrode layer 600, and the lower protective film layer 900 is arranged on the back side of the lower electrode layer 700. (Electronic control module) The electronic control module 300 is mounted on the inner board 200. It is electrically connected to a flexible flat panel cable (FPC) with a 1000 connector. Positive and negative terminals are led out from the upper electrode layer 600 and the lower electrode layer 700, and then electrically connected to the electronic control module 300 via the FPC with the 1000 connector. This FPC with the 1000 connector facilitates the connection of the upper electrode layer 600 and the lower electrode layer 700 with the electronic control module 300, allowing the electronic control module 300 to control different voltages via a driver IC chip. Different patterns are displayed by applying different voltages to the electrode layer. When using plastic material, there are two ways to integrate it with the outer panel 100. One way is that the upper protective film layer has a mating surface that mates with the inner side of the outer panel 100, with an adhesive layer 1001 on the mating surface. The electronic ink luminescent display module 1009 is attached to the display area 400 on the inner side of the outer panel 100 via the adhesive layer 1001. Another way is that the outer panel 100 is made of plastic, and the electronic ink luminescent display module 1009 is formed in the display area 400 on the inner side of the outer panel 100 through insert injection molding. It can be seen that the electronic ink luminescent display module 1009 is formed directly as an insert or installed via the adhesive layer 1001. Similarly, the adhesive layer 1001 can be OCA adhesive or OCR adhesive. The outer surface of the outer panel 100 has a hardened coating 1005. When using plastic material, the hardened coating 1005 serves both a protective function and can also block harmful ultraviolet rays from reaching the electronic ink layer 500. Figure 6As shown, or by providing a PUR layer 1006 on the outer surface of the outer panel 100, the PUR layer 1006 serves as a substitute for paint and also blocks harmful ultraviolet rays from the electronic ink layer 500. Similarly, a conductive ink pattern layer 1003 is arranged between the electronic ink layer 500 and the lower electrode layer 700 or between the lower electrode layer 700 and the lower protective film layer 900. The conductive ink pattern layer 1003 allows for printing any pattern on the back of the electronic ink layer, resulting in a better appearance in actual use. To protect the entire electronic ink light-emitting display module 1009, a sealing cover 1004 is also provided on the upper back of the display area 400 to protect the electronic ink light-emitting display module 1009. The sealing cover 1004 is installed and connected to the inner panel 200. The sealing cover 1004 prevents moisture from entering the electronic ink light-emitting display module 1009, which could lead to product failure.

[0035] Regardless of whether the outer panel 100 is made of glass or plastic, this patent primarily utilizes electronic ink (E-ink) technology. The electronic ink layer 500 is printed onto a film layer. The upper protective film layer 800 and the lower protective film layer 900 primarily serve an encapsulation and protection function. Since electronic ink (E-ink) technology uses natural light projection onto the film layer and displays brightness through reflection, a backlight can be eliminated, replacing the lighting method with an luminous source. Furthermore, the upper electrode layer 600 and the lower electrode layer 700 can form a conductive circuit with the electronic control module 300 during use. The electronic ink in this patent… Layer 500 is mainly composed of a large number of microcapsules, which are only the size of a human hair. The black and white spheres in the microcapsules are pigment particles with different charges. In the initial state, the pigment particles are suspended in the microcapsules. The electronic control module 300 controls different voltages through the driver IC chip. After different voltages are applied through the electrode layer, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. The microcapsules of different colors form various texts and patterns. The power consumption is only about 8% of that of the light source, thus achieving ultra-low power consumption. After being combined with the column plate component, there is no longer any range anxiety caused by power consumption due to light emission.

[0036] The entire process of creating the intelligent column panel is as follows:

[0037] 1. First, the capsule-type electronic ink layer 500 is coated onto a PC / PET film. Then, a conductive ink pattern layer 1003, such as any pattern like the letter M, is printed on the back of the electronic ink layer 500. The upper electrode layer 600 and the lower electrode layer 700 are printed. The upper electrode layer 600 and the lower electrode layer 700 are not limited to silver paste, ink, or other conductive materials, and the positive and negative electrodes are brought out. Then, the electronic control module 300 is connected through a flexible flat cable (FPC) 1000. The electronic control module 300 uses a driver IC chip to control different voltages, thereby displaying different patterns.

[0038] 2: The outer panel 100 and inner panel 200 of the intelligent column are injection molded or glued together; if the outer panel 100 is made of glass, a weather-resistant ink layer 1002 is formed by printing and spraying weather-resistant ink on the inside; if the outer panel is made of plastic, the plastic outer panel is initially transparent. To facilitate the display of the pattern, an outer panel with a transmittance of 90% is generally used. The outer panel can be made of PC or PMMA material. First, a masking black paint is sprayed on the back of the outer panel 100 to laser engrave the light-emitting display pattern area, or a corresponding rectangular light-emitting display pattern area is masked on the back of the outer panel 100 and then a masking black paint is sprayed. The outer surface of the outer panel 100 is sprayed with a hardening-resistant coating 1005; the pattern of the outer panel 100 can be fixed; the inner panel 200 is made of plastic. The inner panel 200 needs to be cleared at the position of the display pattern to reserve space for the electronic ink light-emitting display module 1009 to be attached. Here, the light-emitting display pattern can be a dynamic flow from top to bottom and then the overall display pattern is presented, or the display pattern can be presented directly.

[0039] 3: Two protective films, an upper protective film layer 800 and a lower protective film layer 900, are encapsulated on the electronic ink PC / PET film to prevent moisture from entering the electronic ink film and causing product failure; OCA adhesive is applied to the bonding surface and attached to the back of the outer board 100; or the electronic ink film can be directly attached with OCR adhesive.

[0040] 4. The glued electronic ink light-emitting display module 1009 can be covered with a sealing cover 1004 using glue or butyl glue 1007 to prevent moisture from entering and ensure that the product will not fail.

[0041] 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.

[0042] 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.
