Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a circular liquid crystal panel, a circular LCD module, and a watch. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of display used in digital clocks and many portable computers. An LCD display uses two polarized materials with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to rearrange, blocking light from passing through them. Thus, each crystal acts like a Venetian blind, both allowing light to pass through and blocking it.

[0003] like Figure 11 and Figure 12 The LCD module shown is used in wearable watches. It displays segmented content in a circular shape and mainly consists of LCD1-5 and a backlight 1-1. Because the liquid crystal inlet 1-4 of the LCD is at the top, LCD1-5 cannot be designed in a circular shape there, and a sealing adhesive 1-3 needs to be applied. Since the sealing adhesive 1-3 is raised, a window 1-2 needs to be opened in the backlight 1-1 to avoid obstructing the sealing adhesive 1-3 of the LCD1-5; otherwise, it will be damaged by pressure, and the display function of the LCD1-5 will also be affected. However, opening a window 1-2 in the backlight 1-1 not only poses a risk of light leakage, but also allows dust and foreign objects to easily enter, affecting the display effect. Furthermore, the display area of ​​LCD1-5 cannot be designed in a circular shape, affecting its aesthetics. Utility Model Content

[0004] Therefore, it is necessary to address the aforementioned technical problems by providing a circular LCD panel, a circular LCD module, and a watch, which places the liquid crystal packaging port on the bottom of the traditional LCD, thus solving the problems of easy dust ingress, light leakage, and the inability to achieve a circular design.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A circular liquid crystal panel includes a circular liquid crystal assembly;

[0007] The circular liquid crystal assembly includes an upper glass and a lower glass that are bonded together. A sealed space for liquid crystal filling is formed between the upper glass and the lower glass. A liquid crystal filling port is provided on one side of the bonding area on the circular liquid crystal assembly, and the liquid crystal filling port is connected to the sealed space for liquid crystal filling.

[0008] Furthermore, the liquid crystal filling port is coated with sealing adhesive.

[0009] Furthermore, LCD driving signal pin one and LCD driving signal pin two are respectively provided on both sides of the bonding area, wherein the liquid crystal filling port is located at the center between LCD driving signal pin one and LCD driving signal pin two.

[0010] Furthermore, the bonding area is located on one side of the upper glass and is integrally formed therewith.

[0011] Furthermore, the bonding area is located on one side of the lower glass and is integrally formed therewith.

[0012] A circular LCD module includes a circular liquid crystal panel and a backlight module, wherein the backlight module has a receiving groove for inserting the circular liquid crystal component therein.

[0013] An LCD FPC is bonded to the circular liquid crystal component, and a backlight FPC is bonded to the backlight module.

[0014] One end of the backlight FPC is bonded to the back of the LCD FPC.

[0015] Furthermore, the LCD FPC includes an LCD FPC body, one end of which has a first bonding end and the other end has a second bonding end.

[0016] Furthermore, a clearance groove is provided in the middle of the first binding end at the position corresponding to the liquid crystal filling port;

[0017] The clearance slot separates the first binding end into a first left binding end and a first right binding end, which are respectively bound to the corresponding LCD drive signal pin one and LCD drive signal pin two.

[0018] Furthermore, a stress-dispersing chamfer is formed at the inner corner of the avoidance groove.

[0019] A watch includes a circular LCD module and a housing. The circular LCD module is installed inside the housing. A cover plate is embedded on the surface of the housing. The area of ​​the cover plate outside the circular LCD module is screen-printed with ink. The ink on the cover plate can cover and shield the area outside the circular LCD module.

[0020] The top and bottom of the casing are both connected to watch straps.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This utility model provides a circular liquid crystal panel, a circular LCD module, and a watch. The liquid crystal filling port, which is traditionally placed at the top, is designed at the bottom of the circular liquid crystal component. This eliminates the need for a separate clearance design at the edge of the backlight module, thereby reducing the problems of dust infiltration and light leakage caused by clearance. At the same time, since the liquid crystal filling port in this application is specifically located on the bonding area, the circular liquid crystal component has an overall arc-shaped design, making its overall edges smoother and achieving a more aesthetically pleasing display area.

[0023] By designing the LCD FPC body and its clearance groove, the requirements for bonding and connecting LCD drive signal pin 1 and LCD drive signal pin 2 are met. At the same time, the clearance groove design allows the liquid crystal filling port to be exposed, which facilitates the assembly of the circular liquid crystal component. In addition, the stress-dispersing chamfer design allows the corners of the clearance groove to be rounded, avoiding stress concentration that could easily lead to tearing.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0042] As described in the background art, such as Figure 11 and Figure 12The LCD module shown is used in wearable watches. It displays segmented data in a circular format and mainly consists of LCD1-5 and a backlight 1-1. Because the liquid crystal inlet 1-4 of the LCD is at the top, LCD1-5 cannot be designed in a circular shape there, and a sealing adhesive 1-3 is required. Since the sealing adhesive 1-3 is raised, a window 1-2 needs to be created in the backlight 1-1 to avoid obstructing the sealing adhesive 1-3, otherwise it will be damaged and affect the display function of LCD1-5. However, creating a window 1-2 in the backlight 1-1 not only poses a risk of light leakage but also allows dust and foreign objects to easily enter, affecting the display effect. Furthermore, the display area of ​​LCD1-5 cannot be designed in a circular shape, affecting its aesthetics.

[0043] To solve this technical problem, this utility model provides a circular liquid crystal panel, a circular LCD module, and a watch, which are applied to liquid crystal displays.

[0044] For details, please refer to Figures 1-12 As shown, the circular liquid crystal panel specifically includes a circular liquid crystal assembly 1. The circular liquid crystal assembly 1 includes an upper glass 11 and a lower glass 12 that are bonded together. A sealed space for liquid crystal filling is formed between the upper glass 11 and the lower glass 12. A liquid crystal filling port 13 is provided on one side of the bonding area 14 on the circular liquid crystal assembly 1, and the liquid crystal filling port 13 communicates with the sealed space for liquid crystal filling.

[0045] This utility model provides a circular liquid crystal panel, a circular LCD module, and a watch. The liquid crystal filling port 13, which is traditionally placed at the top, is designed at the bottom of the circular liquid crystal component 1. This eliminates the need for a separate clearance design at the edge of the backlight module 2, thereby reducing the problems of dust infiltration and light leakage caused by clearance. At the same time, since the liquid crystal filling port 13 in this application is specifically located on the bonding area 14, the circular liquid crystal component 1 has an overall arc-shaped design, making its overall edges smoother and achieving a more aesthetically pleasing display area.

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0049] Example 1

[0050] Please refer to Figures 1-12 As shown, a circular liquid crystal panel includes a circular liquid crystal assembly 1. The circular liquid crystal assembly 1 includes an upper glass 11 and a lower glass 12 that are bonded together. A sealed space for liquid crystal filling is formed between the upper glass 11 and the lower glass 12. A liquid crystal filling port 13 is provided on one side of the bonding area 14 on the circular liquid crystal assembly 1. Figure 10 The upper glass 11 and the lower glass 12 are provided with a frame 19 to form a closed space, and the liquid crystal filling port 13 is connected to the sealed space for filling liquid crystal.

[0051] like Figure 5 As shown, the liquid crystal filling port 13 is coated with sealing adhesive 18. The two sides of the bonding area 14 are respectively provided with LCD driving signal pin 15 and LCD driving signal pin 2 16. The liquid crystal filling port 13 is located at the center between the LCD driving signal pin 15 and the LCD driving signal pin 2 16. This allows the liquid crystal filling port 13 to be located at the bottom of the circular liquid crystal component 1, making the display area of ​​the circular liquid crystal component 1 smoother and improving the overall aesthetics.

[0052] like Figure 9 As shown, the bonding area 14 is located on one side of the lower glass 12 and is integrally formed with it; or, as... Figure 10 As shown, the bonding area 14 is located on one side of the upper glass 11 and is integrally formed with it;

[0053] This embodiment uses the following method: Figure 9 The design shown depicts the binding area 14 being located on the lower glass 12. However, in actual applications, the binding area 14 can also be located on the upper glass 11 depending on the specific circumstances. This embodiment does not elaborate further on the design of the binding area 14 on the upper glass 11.

[0054] like Figure 11 and Figure 12 The diagram shows a conventional LCD filling port design, with LCD filling ports 1-4 located at the top of LCD1-5. Therefore, as shown... Figure 11 The positions of the liquid crystal filling ports 1-4 shown are flat, which results in the overall shape of LCD1-5 not being very smooth, and the aesthetics are greatly reduced compared to this application.

[0055] The liquid crystal filling port 13 is coated with sealing adhesive 18, which can seal and seal the liquid crystal filling port 13 after liquid crystal is injected.

[0056] Meanwhile, since the liquid crystal filling port 13 is designed at the bottom of the circular liquid crystal component 1 in this embodiment, and the liquid crystal filling port 13 is still located in the lower middle position of the whole machine, there is still some distance from the edge. Therefore, after the outer cover plate 41 is covered, the liquid crystal filling port 13 can be effectively covered and protected. At the same time, there is no need to open a window at the edge of the backlight module 2, which would easily cause the problem of light leakage and dust ingress (because when a window is opened at the edge of the backlight module 2, the edge of the cover plate is too close to the opening position, which may not be able to effectively cover and block the opening).

[0057] The circular liquid crystal assembly 1 in this embodiment also includes an upper polarizer 110 attached to the surface of the upper glass 11 and a lower polarizer 120 attached to the surface of the lower glass 12. A color filter (not shown in the figure) is also provided between the upper glass 11 and the lower glass 12. The related structures, which are not shown, are known structures used to meet the normal display requirements of the circular liquid crystal assembly 1, and need not be further described in this embodiment.

[0058] Example 2

[0059] This embodiment is based on Embodiment 1. Please refer to the following for details. Figures 1-10 As shown, a circular LCD module includes a circular liquid crystal panel and a backlight module 2. The backlight module 2 has a receiving groove 22 for inserting the circular liquid crystal component 1 therein.

[0060] An LCD FPC3 is bonded to the circular liquid crystal component 1, and a backlight FPC21 is bonded to the backlight module 2.

[0061] One end of the backlight FPC21 is bonded to the back of the LCD FPC3;

[0062] The LCD FPC3 includes an LCD FPC body 31, one end of which has a first bonding end 32 and the other end has a second bonding end 33;

[0063] An avoidance groove 34 is provided at the middle of the first binding end 32 corresponding to the position of the liquid crystal filling port 13;

[0064] The clearance slot 34 causes the first binding end 32 to be divided into a first left binding end 35 and a first right binding end 36. The first left binding end 35 and the first right binding end 36 are respectively bound and connected to the corresponding LCD driving signal pin 15 and LCD driving signal pin 26.

[0065] In this embodiment, an avoidance groove 34 is designed at the position corresponding to the liquid crystal filling port 13, so as to avoid obstruction between the LCD FPC3 and the liquid crystal filling port 13 when the LCD FPC3 is bonded to the circular liquid crystal component 1, thus affecting the overall assembly of the module.

[0066] like Figure 6 As shown, as a further optimization of this embodiment, a stress-dispersing chamfer 17 is formed at the inner corner of the relief groove 34. Through the design of the stress-dispersing chamfer 17, the concentrated stress at the corner inside the relief groove 34 can be dispersed. By dispersing the stress, the problem of the LCD FPC body 31 being easily torn due to excessive stress concentration can be avoided.

[0067] Example 3

[0068] This embodiment is based on Embodiment 2, with further optimizations to the circular LCD module. Please refer to the following for details. Figures 1-10 As shown, a watch includes a circular LCD module and a housing 4. The circular LCD module is installed inside the housing 4, and a cover plate 41 is embedded on the surface of the housing 4.

[0069] The area outside the circular liquid crystal component 1 corresponding to the cover plate 41 is screen-printed with ink 43. The area outside the circular liquid crystal component 1 can be covered and blocked by the ink 43 on the cover plate 41. The top and bottom of the housing 4 are connected to the watch strap 42.

[0070] like Figure 3 The receiving slot 22 shown is used for the placement of the circular liquid crystal component 1. The circular liquid crystal component 1 placed inside is bonded to the LCD FPC body 31 by the backlight FPC 21, and then the bonded whole is placed inside the housing 4. After the circuit board and power supply components (not shown in the figure) inside are connected, the cover plate 41 is sealed. Since the cover plate 41 has ink 43, the ink 43 can block the area outside the display area of ​​the circular liquid crystal component 1, thereby further improving the overall aesthetics.
