Description
Technical Field
[0001] This utility model belongs to the field of automotive intelligent display technology, specifically relating to an electronic ink light-emitting display module for automotive intelligent displays. Background Technology
[0002] As the market share of electric vehicles increases, all products in electric vehicles that require illumination will consume electricity. Consumers demand not only aesthetically pleasing and personalized appearances, but also certain luminous functionalities, such as on smart front fascias or pillar panels. Existing luminous displays use LCD screens, COB, light guides, light strips, optical fibers, and LEDs as their light sources. This not only places high demands on product placement space and has limited compatibility with various exterior decorations, but also results in relatively high power consumption. If electronic ink (E-ink) technology is used, the power consumption is only about 8% of that of products with light sources, and it has ultra-low power consumption. This allows for the display of different patterns on the decorative parts and eliminates concerns about use when the electric vehicle's range is insufficient. However, current electronic ink (E-ink) technology is mainly used in devices such as e-readers and there is no corresponding solution for integration with smart front fascias or pillar panels. Therefore, it is necessary to develop an electronic ink luminous display module that can provide intelligent displays on smart front fascias or pillar panels. Utility Model Content

[0019] Figure 2 This is a schematic diagram of the second implementation of the electronic ink luminescent display module for automotive intelligent display;
[0020] Figure 3 This is a schematic diagram of the third implementation method of the electronic ink luminescent display module for automotive intelligent display. Detailed Implementation
[0021] 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.
[0022] In the figure, the electronic ink layer is 100; the upper electrode layer is 200; the lower electrode layer is 300; the upper protective film layer is 400; the lower protective film layer is 500; the ink pattern layer is 600; the UV coating is 700; and the adhesive layer is 800.
[0023] Example 1
[0024] like Figure 1 As shown, the electronic ink luminescent display module of this automotive intelligent display mainly includes an electronic ink layer assembly and an encapsulation film layer. The encapsulation film layer encapsulates the electronic ink layer assembly. The electronic ink layer assembly includes an electronic ink layer 100, an upper electrode layer 200, and a lower electrode layer 300. The upper electrode layer 200 and the lower electrode layer 300 are respectively arranged on the front and back sides of the electronic ink layer 100. The upper electrode layer 200 and the lower electrode layer 300 can form a conductive circuit. Here, the electronic ink layer 100 is usually made into a thin film composed of a large number of microcapsules. These microcapsules are only the diameter 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. After applying different voltages through the electrode layer, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. Microcapsules form various texts and patterns. Since electronic ink emits light through reflection, its overall power consumption is low. Therefore, when combined with automotive components, there is no longer any range anxiety caused by power consumption due to light emission. In this patent, the electronic ink layer 100 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. The encapsulation film layer includes an upper protective film layer 400 and a lower electrode layer 300. The upper protective film layer 400 is arranged on the front side of the upper electrode layer 200, and the lower protective film layer 500 is arranged on the back side of the lower electrode layer 300 for encapsulation. Here, the encapsulation is achieved through a sandwich structure formed by the upper protective film layer 400 and the lower protective film layer 500, which can prevent moisture from entering the electronic ink layer 100 and causing product failure. Since it can be in the form of a thin film, it has a wide range of applications and low requirements for product layout space.
[0025] Example 2
[0026] Most of the structure in this embodiment is the same as in embodiment 1. The difference is that, as a further optimization, an ink pattern layer 600 is also arranged between the electronic ink layer 100 and the lower electrode layer 300, or the ink pattern layer 600 is arranged between the lower electrode layer 300 and the lower protective film layer 500. Here, the ink pattern layer 600 can initially set the corresponding pattern, so that the appearance effect is better in actual use. Here, the ink pattern layer 600 is a conductive ink pattern layer, which makes it convenient to combine with the electrode layer for use.
[0027] Example 3
[0028] Most of the structure in this embodiment is the same as in embodiment 2. The difference is that a UV coating 700 is added on the basis of embodiment 2. Here, the UV coating 700 can be arranged on the front of the upper protective layer or between the upper protective layer and the upper electrode layer 200. Here, the UV coating 700 serves two purposes: protection and blocking specific ultraviolet rays to prevent specific ultraviolet rays from damaging the electronic ink layer 100. The entire electronic ink light-emitting display module can be used as an insert with other components or after being glued. When using the adhesive method, the upper or lower protective layer also has an adhesive layer 700. The adhesive layer 700 is an OCA adhesive layer or an OCR adhesive layer. It can be directly attached to the corresponding automotive parts using the OCA adhesive layer or the OCR adhesive layer.
[0029] 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.
[0030] 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.
