Description

Technical Field

[0001] The invention belongs to the technical field of automobile intelligent column plates, and in particular relates to an intelligent column plate with electronic ink luminous display. Background Art

[0002] As the market share of electric vehicles increases, all products that need to emit light in electric vehicles will use electricity. If electronic ink (E-lnk) technology is used, the trim can display different patterns, and there is no need to worry about using it when the electric vehicle mileage is insufficient. Here, take the B-pillar board of the car as an example. In the welcoming mode, when the owner walks towards the door from a distance, the B-pillar board dynamically emits light and flows to welcome the owner's arrival; when the door is exited, the pattern on the B-pillar board also emits light to send off the owner. When the electric car is in charging mode, different luminous colors on the B-pillar board can represent different charging states: such as charging start, charging, charging end, and charging failure, etc.; However, some existing exterior luminous displays on the market use LCD display screens, light strips, optical fibers, LEDs, etc. as the light source, and the light source module is large, requiring more space to be arranged on the back of the product, and the light mode using LCD display screens, light strips, optical fibers, LEDs, etc. has relatively high power consumption, so it is necessary to design a new intelligent column board with luminous display. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent column panel with electronic ink luminous display in response to the current status of the prior art. By adopting electronic ink (E-lnk) technology, the electronic ink is printed on a membrane, and natural light is projected on the membrane and displayed through reflected brightness, thereby achieving ultra-low power consumption function and solving the product layout space requirements.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an intelligent column panel with electronic ink luminous display, characterized in that it includes an outer panel, an inner panel, an electronic ink luminous display module and an electronic control module, a display area is provided between the outer panel and the inner panel, the electronic ink luminous display module is installed in the display area, the electronic ink luminous display module is electrically connected to the electronic control module, and the electronic control module controls the electronic ink luminous display module to display different patterns on the intelligent column panel.

[0005] Preferably, in the above-mentioned smart column panel with electronic ink luminous display, the electronic ink luminous 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 of the electronic ink layer. The upper protective film layer is arranged on the front of the upper electrode layer and the lower protective film layer is arranged on the back of the lower electrode layer.

[0006] Here, this patent mainly uses electronic ink (E-lnk) technology. By printing the electronic ink layer on the membrane layer, the main function of the upper protective membrane layer and the lower protective membrane layer is encapsulation protection. Since the electronic ink (E-lnk) technology uses natural light to project on the membrane layer and display through reflected brightness, the backlight source can be eliminated and replaced with the lighting method of the luminous light source. The upper electrode layer and the lower electrode layer can form a conductive circuit with the electronic control module when in use. The electronic ink layer in this patent is mainly composed of a large number of microcapsules. These microcapsules are only the size of the diameter of human hair. The black and white balls 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 controls different voltages through the driver IC chip. After loading different voltages through the electrode layer, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. Microcapsules of different colors form various texts and patterns. The power consumption is only about 8% of the light source, thereby achieving ultra-low power consumption. After combining with the column plate component, there is no need to worry about the mileage anxiety caused by power consumption for light emission.

[0007] In the above-mentioned smart column board with electronic ink luminous display, the electronic control module is electrically connected with a flexible flat cable FPC tape, and the positive and negative electrodes of the upper electrode layer and the lower electrode layer are led out and then electrically connected to the electronic control module through the flexible flat cable FPC tape.

[0008] Here, the soft cable FPC tape can be used to easily lead out the positive and negative poles of the upper electrode layer and the lower electrode layer for connection with the electronic control module, so that different voltages can be controlled by the driver IC chip inside the electronic control module, and different patterns can be displayed after loading different voltages through the electrode layer.

[0009] Preferably, in the above-mentioned smart column board with electronic ink light-emitting 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. Here, any pattern can be printed on the back of the electronic ink layer through the conductive ink pattern layer, so that the appearance effect is better in actual use.

[0010] Preferably, in the above-mentioned smart column panel with electronic ink luminous display, the outer panel is made of glass, the inner side of the outer panel is printed or sprayed with a weather-resistant ink layer, the upper protective layer has a bonding surface that matches the inner side of the outer panel, and the bonding surface has a glue layer, and the electronic ink luminous display module is attached to the back of the weather-resistant ink layer through the glue layer.

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

[0012] Preferably, in the above-mentioned smart column panel with electronic ink luminous display, the outer panel is made of plastic, the upper protective layer has a fitting surface matching the inner side of the outer panel, the fitting surface has a glue layer, and the electronic ink luminous display module is attached to the display area on the inner side of the outer panel through the glue layer.

[0013] As another embodiment, in the above-mentioned smart column panel with electronic ink luminous display, the outer panel is made of plastic, and the electronic ink luminous 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 the electronic ink luminous display module is to directly form it in the form of an insert or install it through a glue layer. Similarly, the glue layer here can be OCA glue or OCR glue.

[0015] In the above-mentioned smart column board with electronic ink luminous display, the outer surface of the outer plate has a hardened coating. When plastic material is used here, the hardened coating plays a protective role on the one hand, and can also isolate ultraviolet rays that are harmful to the electronic ink layer on the other hand.

[0016] In the above-mentioned smart column board with electronic ink luminous display, the outer surface of the outer plate has a PUR layer. Here, the PUR layer can replace the paint on one hand, and can also block the ultraviolet rays that are harmful to the electronic ink layer on the other hand.

[0017] In the above-mentioned smart column panel with electronic ink luminous display, the electronic ink luminous display module can display black and white, black and white and red, black and white, red and yellow, and multi-color. Here, by loading different voltages in the same mode, different colors can be displayed to meet the car owner's car use needs under different working conditions.

[0018] In the above-mentioned smart column board with electronic ink luminous display, a sealing cover plate for protecting the electronic ink luminous display module is also provided on the upper back of the display area, and the sealing cover plate is installed and connected to the inner plate. The sealing cover plate can prevent the electronic ink luminous display module from entering with water vapor, which may cause product failure.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The overall power consumption is low, and it can display black and white, black and white and red, black and white, red and yellow, and multi-color. Due to the cancellation of the backlight source, the power consumption of electronic ink accounts for up to 8% of the luminous mode. After combining with the column plate, there is no need to worry about the mileage anxiety caused by power consumption for luminous.

[0021] 2. Electronic ink can completely replace LCD screens, light strips, optical fibers, LEDs, etc. with light sources. It has a wide range of application scenarios and requires little space for product layout and structure;

[0022] 3. The overall package has two layers of protective film to prevent moisture from entering the electronic ink layer, which would cause product failure. The ink pattern layer can also be integrated to display a dynamic welcome pattern / charging status, making users feel at home and improving their car-using experience.

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] In the figure, 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; glue layer 1001; weather-resistant ink layer 1002; conductive ink pattern layer 1003; sealing cover plate 1004; hardened coating 1005; PUR layer 1006; butyl rubber 1007; glue 1008; electronic ink light-emitting display module 1009.

[0031] like Figure 1 and Figure 2As shown, the smart column plate of the electronic ink luminous display can be an A column, a B column or a C column. In this embodiment, the B column plate is taken as an example, which mainly includes an outer plate 100, an inner plate 200, an electronic ink luminous display module 1009 and an electronic control module 300. The outer plate 100 and the inner plate 200 are bonded by glue 1008. There is a display area 400 between the outer plate 100 and the inner plate 200. The electronic ink luminous display module 1009 is installed in the display area 400. The electronic ink luminous display module 1009 is mainly used to display patterns. Therefore, the inner plate 200 at the display pattern position needs to be designed to avoid air, and a space that can fit the electronic ink luminous display module 100 is reserved. 9 display area 400, for the convenience of control, the electronic ink light-emitting display module 1009 is electrically connected to the electronic control module 300, and the electronic control module 300 controls different voltages through the driving IC chip so that different patterns are displayed on the electronic ink light-emitting display module 1009. The electronic ink light-emitting display module 1009 can display black and white, black and white and red, black and white, red and yellow, and multiple colors. Here, different voltages are loaded in the same mode to display different colors, which can meet the car owner's car use needs under different working conditions. The light-emitting display pattern can be a dynamic flow from top to bottom - and then present the display pattern as a whole, or it can directly present the display pattern.

[0032] Specifically, the inner panel 200 is mainly made of plastic material, and the outer panel 100 can be made of plastic or glass. The different materials of the outer panel 100 are described below.

[0033] like Figure 3 as well as Figure 4As shown, when the outer panel 100 is made of glass, as the core of the light-emitting display, the electronic ink light-emitting display module 1009 in this patent 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 arranged on the front and back of the electronic ink layer 500 respectively. The upper protective film layer 800 is arranged on the front of the upper electrode layer 600 and the lower protective film layer 900 is arranged on the back of the lower electrode layer 700. The electronic control module 300 is installed on the inner panel 200. The sub-control module 300 is electrically connected to a flexible flat cable FPC tape 1000, and the upper electrode layer 600 and the lower electrode layer 700 lead out positive and negative electrodes and then electrically connect to the electronic control module 300 through the flexible flat cable FPC tape 1000. Here, the flexible flat cable FPC tape 1000 can facilitate the upper electrode layer 600 and the lower electrode layer 700 to lead out positive and negative electrodes and connect to the electronic control module 300, so that different voltages are controlled by the driving IC chip inside the electronic control module 300, and different patterns are displayed after different voltages are loaded on the electrode layer. A weather-resistant ink layer 1002 is printed or sprayed on the inner side of the glass, and the upper protective layer has a connection with the inner side of the outer plate 100. The mating surface has a glue layer 1001 on the mating surface. The electronic ink light-emitting display module 1009 is attached to the back of the weather-resistant ink layer 1002 through the glue layer 1001. When the outer plate 100 is made of glass, it is first necessary to print or spray the weather-resistant ink layer 1002. The weather-resistant ink layer 1002 can be used to shield and isolate the ultraviolet rays that are harmful to the electronic ink layer 500. Then, the glue layer 1001 is attached to the back of the weather-resistant ink layer 1002 for installation. Here, the glue layer 1001 can be made of OCA glue or OCR glue. As a further optimization, the electronic ink layer 500 and the lower electrode layer 700 A conductive ink pattern layer 1003 is arranged 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 for protecting the electronic ink light-emitting display module 1009 is also provided on the upper back of the display area 400. The sealing cover plate 1004 is installed and connected to the inner plate 200. Here, the sealing cover plate 1004 can prevent the electronic ink light-emitting display module 1009 from entering with water vapor, which causes product failure.

[0034] like Figure 3 as well as Figure 5As shown, when the outer plate 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 arranged on the front and back of the electronic ink layer 500, respectively. The upper protective film layer 800 is arranged on the front of the upper electrode layer 600 and the lower protective film layer 900 is arranged on the back of the lower electrode layer 700. The electronic control module 300 is installed on the inner plate 200, the electronic control module 300 is electrically connected with the soft flat cable FPC tape 1000, the upper electrode layer 600 and the lower electrode layer 700 lead out the positive and negative electrodes and then electrically connect the electronic control module 300 through the soft flat cable FPC tape 1000, here, the soft flat cable FPC tape 1000 can facilitate the upper electrode layer 600 and the lower electrode layer 700 to lead out the positive and negative electrodes and connect them to the electronic control module 300, so that different voltages can be controlled by the driving IC chip inside the electronic control module 300 , different patterns are displayed after different voltages are loaded on the electrode layer. When plastic material is used here, there are two ways to combine with the outer panel 100. One is that the upper protective layer has a fitting surface that matches the inner side of the outer panel 100, and a glue layer 1001 is provided on the fitting surface. The electronic ink light-emitting display module 1009 is attached to the display area 400 on the inner side of the outer panel 100 through the glue layer 1001. As another way, the outer panel 100 is made of plastic material, and the electronic ink light-emitting display module 1009 is formed at the display area 400 on the inner side of the outer panel 100 by insert injection molding. It can be seen that one way of the electronic ink light-emitting display module 1009 is to form it directly in the form of an insert or to install it through the glue layer 1001. Similarly, the glue layer 1001 here can be made of OCA glue or OCR glue. There is a hardening coating 1005 on the outer surface of the outer panel 100. When plastic material is used here, the hardening coating 1005 plays a protective role on the one hand, and on the other hand, it can also isolate ultraviolet rays that are harmful to the electronic ink layer 500, such as Figure 6As shown, or by setting a PUR layer 1006 on the outer surface of the outer plate 100, the PUR layer 1006 can replace the paint on the one hand, and can also block the ultraviolet rays that are harmful to the electronic ink layer 500 on the other hand. 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. 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 for protecting the electronic ink light-emitting display module 1009 is also provided on the upper back of the display area 400. The sealing cover plate 1004 is installed and connected to the inner plate 200. Here, the sealing cover plate 1004 can prevent the electronic ink light-emitting display module 1009 from entering with water vapor, which causes product failure.

[0035] Here, no matter whether the outer plate 100 is made of glass or plastic, the electronic ink (E-lnk) technology is mainly used in this patent. By printing the electronic ink layer 500 on the film layer, the upper protective film layer 800 and the lower protective film layer 900 mainly serve as packaging protection. Since the electronic ink (E-lnk) technology uses natural light to project on the film layer and display the brightness through reflection, the backlight source can be eliminated and replaced by the lighting method of the luminous light source. In addition, the upper electrode layer 600 and the lower electrode layer 700 can form a conductive circuit with the electronic control module 300 when in use. The electronic ink in this patent Layer 500 is mainly composed of a large number of microcapsules, which are only the size of the diameter of human hair. The black and white balls 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 loading different voltages through the electrode layer, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. Microcapsules of different colors form various texts and patterns. The power consumption is only about 8% of the light source, thereby achieving ultra-low power consumption. After combining with the column plate components, there is no need to worry about mileage anxiety caused by power consumption for light emission.

[0036] The process of making the entire smart column plate is as follows:

[0037] 1: First, the capsule electronic ink layer 500 is coated on the PC / PET film, and the conductive ink pattern layer 1003 is printed on the back of the electronic ink layer 500, such as any pattern such as the M logo, by printing the upper electrode layer 600 and the lower electrode layer 700, the upper electrode layer 600 and the lower electrode layer 700 are not limited to silver paste, ink and other conductive materials, and the positive and negative electrodes are led out; then the electronic control module 300 is connected through the flexible cable FPC tape 1000; the electronic control module 300 uses a driver IC chip to control different voltages to display different patterns.

[0038] 2: The outer panel 100 and the inner panel 200 of the smart column are combined by injection molding or gluing; if the outer panel 100 is made of glass, a weather-resistant ink layer 1002 is formed by printing and spraying on the inner side; if a plastic outer panel is used, the initial state of the plastic outer panel is transparent. In order to facilitate the display of patterns, 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 a luminous display pattern area, or a corresponding rectangular luminous 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 qualitative; the inner panel 200 is made of plastic, and the inner panel 200 needs to avoid air at the display pattern position, and a space is reserved for the electronic ink luminous display module 1009. The luminous display pattern here can be a dynamic flow from top to bottom-and then the display pattern is presented as a whole, or the display pattern can be presented directly.

[0039] 3: The electronic ink PC / PET film is encapsulated with two layers of protective films, the upper protective film layer 800 and the lower protective film layer 900, to prevent the electronic ink layer from entering with water vapor, which may cause product failure; the bonding surface is covered with OCA glue and affixed to the back of the outer panel 100; or the electronic ink film is directly affixed with OCR glue;

[0040] 4: The pasted electronic ink light-emitting display module 1009 can be glued to the sealing cover plate 1004 by glue or butyl adhesive 1007, which can once again prevent water vapor from entering and ensure that the product will not fail.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
