[0029] The present application is described below based on examples, but the present application is not limited to only these examples. In the following detailed description of the present application, some specific details are described in detail, in order to avoid confusion of the essence of the utility model, the well-known methods, processes, procedures, elements are not described in detail.

[0030] In addition, the drawings provided herein should be understood by those of ordinary skill in the art for illustrative purposes, and the drawings are not necessarily drawn to scale.

[0031] Unless the context clearly requires otherwise, throughout the description and the claims, "comprise", "comprise", and similar words such as "comprise" should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".

[0032] In the description of the present application, it should be understood that the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.

[0033] The present application provides a shockproof segment code display screen, such as Figures 1-4As shown, the system includes a first substrate 1, a second substrate 2, a first electrode layer 3, a second electrode layer 4, a liquid crystal layer 5, and shock-absorbing points 6. The first substrate 1 and the second substrate 2 are disposed opposite each other. The first electrode layer 3 is disposed on the side of the first substrate 1 facing the second substrate 2, and the second electrode layer 4 is disposed on the side of the second substrate 2 facing the first substrate 1. The liquid crystal layer 5 and the shock-absorbing points 6 are both disposed between the first electrode layer 3 and the second electrode layer 4. A display area 9 is etched on the first electrode layer 3 and / or the second electrode layer 4. The shock-absorbing points 6 are spaced at a preset distance from the edge of the display area 9, and the arrangement outline of the shock-absorbing points 6 is the same as the outer outline of the display area 9.

[0034] In one specific embodiment, such as Figure 1 As shown, the shockproof segment display screen includes, from top to bottom, a first substrate 1, a first electrode layer 3, a liquid crystal layer 5, a second electrode layer 4, and a second substrate 2. In specific implementations, the first substrate 1 and the second substrate 2 can have the same thickness, for example, the thickness of the first substrate 1 and the second substrate 2 is 0.7 mm. The first electrode layer 3 and the second electrode layer 4 are disposed on the surface of the first substrate 1 and the second substrate 2 on the side opposite to the liquid crystal layer 5 by a coating process, specifically, they can be indium tin oxide (ITO) layers, the thickness of which is preferably 135 nm. The shockproof points 6 can be formed between the first electrode layer 3 and the second electrode layer 4 by a UV offset printing process, and fixed by a pressing and UV curing process, thereby forming a stable support structure.

[0035] In this embodiment, by setting anti-vibration points 6 between the first electrode layer 3 and the second electrode layer 4, the stability of the segment code screen when subjected to external vibrations is improved, thereby enhancing its anti-vibration performance. Simultaneously, addressing the issue that elongated anti-vibration strips occupy a large area and create shadow areas, thus affecting display effects and aesthetics, this embodiment replaces the elongated anti-vibration strips with dot-shaped anti-vibration points 6. This reduces the space occupied by the anti-vibration points 6 and the shadow areas they create, effectively preventing direct exposure of the anti-vibration point 6 area when the screen is lit, thus improving the display effect and overall aesthetics of the segment code screen.

[0036] Furthermore, such as Figure 2As shown in FIG. 1, multiple shockproof points 6 are arranged between the first electrode layer 3 and the second electrode layer 4. Since the first electrode layer 3 and / or the second electrode layer 4 is etched with display areas 9, the shockproof points 6 need to be arranged away from the display areas 9. In order to improve the shockproof effect of the segment code screen, the shockproof points 6 can be arranged at the edges of the display areas 9 and keep a preset interval distance from the edges of the display areas 9, for example, the interval distance can be set to 0.5 mm, which is not limited in the embodiment. According to the distribution of the display areas 9, the arrangement profile of the shockproof points 6 is the same as the outer profile of the display areas 9, so as to provide a stable support structure while minimizing the impact on the display pattern, ensuring the coordination and unity of the structural stability and display performance of the segment code display screen.

[0037] In the embodiment, the display area 9 refers to an area with a display pattern. It can be understood that, in actual application, since there are multiple display areas 9 in the segment code screen and the shapes are different, when the shockproof points 6 are arranged, the arrangement profile of the shockproof points 6 can be determined in combination with the outer profiles of the multiple display areas 9, rather than being arranged in all non-display areas, so as to take into account the cost benefit and aesthetics. For example Figure 4 As shown in FIG. 1, the view includes multiple display areas 9, one of which is a circular area with a pattern such as a number for displaying vehicle speed information inside the circular area, and multiple shockproof points 6 are arranged outside the circular display area. In addition, since there are other display areas adjacent to the circular display area outside the circular display area, in order to take into account these other display areas outside the circular display area, the arrangement profile of the shockproof points 6 is close to a circle, but not a completely regular circle. Similarly, multiple shockproof points 6 are arranged along the profile of the gap in the circular display area.

[0038] In addition, the circular display area has a pattern such as a number for displaying vehicle speed information, so in order to ensure the display effect, multiple shockproof points 6 can be arranged on the side of the display area where the number is located. At this time, the arrangement profile of the multiple shockproof points 6 can be basically consistent with the profile of the display area where the number is located, which is also a square profile. The corners of the square profile of the shockproof points 6 can be chamfered to improve the shockproof effect and further optimize the display effect.

[0039] In an embodiment of the present application, the shockproof points 6 are circular in the orthographic projection of the display screen.

[0040] In a specific embodiment, any shockproof point 6 is circular in the orthographic projection of the display screen. Compared with a long strip-shaped shockproof strip, the circular shockproof point 6 occupies a smaller area and has better geometric symmetry, which can significantly reduce the shadow area generated, so that the area of the shockproof point 6 is not directly exposed when the screen is lit, and the display effect and aesthetics are better.

[0041] In one embodiment of this application, the diameter of the shock-absorbing point 6 is 0.23-0.27 mm.

[0042] As an example, the diameter of the anti-vibration point 6 can be 0.23mm, 0.24mm, 0.25mm, 0.26mm, or 0.27mm. In a specific embodiment, the diameter of the anti-vibration point 6 is 0.25mm. Compared to a long strip anti-vibration strip with a length of 0.75mm, this embodiment reduces the area occupied by the anti-vibration point 6 by reducing its diameter to the above range, thereby further improving the display effect and aesthetics of the segment code screen.

[0043] In one embodiment of this application, the shock-absorbing point 6 is one or more of a sphere, ellipsoid, or cylinder.

[0044] As an example, the anti-vibration point 6 has a dot-like structure, and its shape includes, but is not limited to, one or more of spheres, ellipsoids or cylinders. Different types of anti-vibration points 6 can be adopted according to specific application requirements. In a specific embodiment, the anti-vibration point 6 adopts a cylindrical anti-vibration point 6 with the same shape and size, so that any anti-vibration point 6 between the first electrode layer 3 and the second electrode layer 4 is subjected to the same external force, so as to ensure the uniformity of the cell thickness and enhance the structural stability of the segment code screen.

[0045] Of course, this is understandable. Figure 3 As shown, the shock-absorbing point 6 can also be frustum-shaped, meaning that the base area of ​​the shock-absorbing point 6 (i.e., the side of the shock-absorbing point 6 that contacts the second substrate 2) is larger than the top area of ​​the shock-absorbing point 6 (i.e., the side of the shock-absorbing point 6 that contacts the first substrate 1). Setting the shock-absorbing point 6 to a frustum shape, with a larger base area, can provide a better buffering effect, thereby improving the shock-absorbing effect of the shock-absorbing segment code screen.

[0046] In one embodiment of this application, the thickness of the shock-absorbing point 6 is 3.5 μm.

[0047] It should be noted that the thickness of the shock-absorbing point 6 is the height of the shock-absorbing point 6 in the direction perpendicular to the first electrode layer and the second electrode layer. In a specific embodiment, the thickness of the shock-absorbing point 6 is fixed at 3.5 μm.

[0048] In one embodiment of this application, a first polarizer and a second polarizer (not shown in the figure) are also included; the first polarizer is disposed on the side of the first substrate 1 facing away from the first electrode layer 3, and the second polarizer is disposed on the side of the second substrate 2 facing away from the second electrode layer 4.

[0049] In one specific embodiment, the first polarizer and the second polarizer are respectively attached to both sides of the first substrate 1 and the second substrate 2 to control the polarization direction of a specific light beam and ensure the normal display of the segment display screen.

[0050] In an embodiment of the present application, a third electrode layer 7 is further included, and the third electrode layer 7 is arranged between the first polarizer and the first substrate 1.

[0051] In a specific embodiment, static electricity is generated on the surface of the first polarizer during the manufacturing, assembling or using of the segment code screen. By adding the third electrode layer 7, the static electricity generated by the first polarizer can be quickly conducted and diffused through the third electrode layer 7, reducing the interference of static electricity on the display effect, thereby effectively avoiding the display residual phenomenon.

[0052] In an embodiment of the present application, a frame glue 8 is arranged along the outer periphery between the first substrate 1 and the second substrate 2 to seal the first substrate 1 and the second substrate 2.

[0053] In a specific embodiment, the first substrate 1 and the second substrate 2 are partially or entirely locally arranged with the frame glue 8 along the outer periphery, and the first substrate 1 and the second substrate 2 are tightly adhered by the frame glue 8 to form a closed and stable internal space, so as to block the liquid crystal layer 5 from the outside and prevent the overflow of liquid crystal molecules, thereby ensuring the normal display of the segment code screen image.

[0054] In an embodiment of the present application, a first flange is arranged on the outer periphery of the first substrate 1, and a second flange is arranged on the outer periphery of the second substrate 2; when the first substrate 1 and the second substrate 2 are attached, the first flange and the second flange are attached to arrange the frame glue between the first flange and the second flange.

[0055] In a specific embodiment, a first flange and a second flange are respectively arranged on the outer periphery of the first substrate 1 and the second substrate 2; when the first substrate 1 and the second substrate 2 are attached, the first flange and the second flange are also attached to each other and the frame glue 8 is arranged therebetween. By arranging the above flange structure, not only the glue injection through the first flange and the second flange is facilitated to ensure that the first substrate 1 and the second substrate 2 are stably attached, but also the use amount of the frame glue on the outer periphery of the substrate is effectively reduced, thereby reducing the material cost.

[0056] In an embodiment of the present application, a flexible circuit board and an integrated chip are further included; the flexible circuit board and the integrated chip are arranged on the second substrate 2 and electrically connected with the display area 9 through the etching line on the second substrate 2 to control the display of the display area 9.

[0057] In a specific embodiment, the area of the first substrate 1 is larger than the area of the second substrate 2, and when the first substrate 1 and the second substrate 2 are attached, there will be some non-display areas of the second substrate 2 which do not coincide with the first substrate 1, and the flexible circuit board and the integrated chip are carried on the above non-display area (film on glass, chip on glass).
