Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a circular display screen structure. Background Art

[0002] At present, the traditional circular display screen is a display screen module designed with circular TFT. For this type of circular TFT, the panel factory has opened molds in relatively few sizes, which cannot meet the personalized design needs of customers, and the cost is relatively high. In many cases, the TFT panel factory has never opened molds for the circular display screen required by customers, and there are no ready-made products to correspond. It is necessary to customize the mold according to customer needs, and the mold fee is very expensive, more than 100,000 US dollars; and there are MOQ requirements, depending on the size. If the size is large, the MOQ requires dozens of K, and if the size is small, the MOQ requires hundreds of K. In addition, the delivery time of the newly opened TFT sample is relatively long, which will delay the customer's product development cycle and delay the product launch. Utility Model Content

[0003] The utility model provides a circular display screen structure, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A circular display screen structure comprises an LCM display screen, a window, a cover plate, a first connection contact, a single-layer PCB board and a second connection contact, wherein the LCM display screen is adhered with a cover plate, a window is provided on the cover plate, a first connection contact is provided on the bottom end of the cover plate, the cover plate is electrically connected to the single-layer PCB board via the first connection contact, and a second connection contact is provided on the bottom end of the single-layer PCB board.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

OCA has good optical properties and can effectively reduce the optical distortion between the display screen and the cover plate 3. This helps to improve the display quality and visual effects of the product, making the displayed content clearer and more realistic. OCA or double-sided tape can achieve uniform force distribution during the lamination process to ensure uniform pressure between the display screen and the cover plate 3. This design can avoid bubbles or gaps caused by uneven lamination and ensure the tightness and stability of the connection. OCA or double-sided tape has good adhesion properties and can firmly bond the display screen and the cover plate 3 together. This bonding method can effectively prevent the display screen and the cover plate 3 from loosening or falling off, and improve the reliability and durability of the product. The use of OCA or double-sided tape can simplify the manufacturing process, reduce the complex assembly steps and the required equipment. Compared with the traditional mechanical fixing method, this bonding method can improve production efficiency and reduce manufacturing costs. The cover plate 3 is made of glass, PS, PV, PMMA or PET materials, which usually have good transparency and can effectively transmit the light of the display screen to provide a clear and bright display effect. In particular, materials such as glass and PMMA (plexiglass) have excellent transparency and can present the content of the display screen to the greatest extent.Materials such as glass and PV have high hardness and wear resistance, can effectively resist scratches and wear, and extend the service life of the product. This is especially important for frequently touched devices such as display screens, which can keep their appearance clear and stable. Compared with glass, materials such as PS (polystyrene), PV (polyvinyl chloride), PMMA (plexiglass) and PET (polyester) are usually lighter, which helps to reduce the weight of the product and reduce the cost of carrying and installation. These materials are usually easy to process and can meet the needs of different shapes and sizes. Whether it is a flat surface or a curved surface design, these materials can flexibly meet the requirements of designers and provide more possibilities for product appearance customization. Compared with glass, materials such as PS, PV, PMMA and PET usually have lower manufacturing costs because their production process is simpler and the cost of raw materials is relatively low. This helps to reduce the manufacturing cost of the product and improve the competitiveness of the product. The cover plate 3 is round or other polygons. Compared with the traditional rectangular or square cover plate 3, the round or polygonal design is more unique and attractive. This non-traditional shape design can add a personality and creativity to the product and attract more consumers' attention. The round or polygonal cover plate 3 design can bring a more beautiful appearance to the product. This shape may be more coordinated with the overall design style of the product, making the product look smoother and simpler. The circular or polygonal design can produce a stronger visual impact and attract the user's attention. It stands out from many similar products and helps to enhance the competitiveness and brand image of the product. Compared with the rectangular or square design, the circular or polygonal cover plate 3 has more flexibility. Designers can use their imagination more freely to create a more colorful product appearance to meet the personalized needs of different users. In some application scenarios, the circular or polygonal design may reduce the complexity and manufacturing cost of the mechanical structure. Compared with the rectangular or square design that requires a right-angle structure, the circular or polygonal structure is easier to manufacture and assemble. A window 2 is provided on the cover plate 3, and the size of the window 2 is adapted to the size of the LCM display screen 1. The window 2 is adapted to the size of the LCM display screen 1, ensuring that all the contents of the display screen can be fully displayed in the window 2, maximizing the display effect. Users can make full use of the entire screen area to obtain a clear and bright display experience. The adaptation of the window 2 to the display screen size can reduce unnecessary blank areas and avoid the waste of screen area caused by the window 2 being too large or too small. This design can make the appearance of the product more compact and improve the screen utilization rate. The window 2 fits tightly to the surface of the display screen, and can effectively protect the display screen from damage by the external environment, such as scratches, dirt, etc. The window 2 of the adapted size can provide better protection and extend the service life of the display screen. The window 2 is adapted to the size of the LCM display screen 1, making it more convenient and comfortable for the user to operate the device.Users do not need to adjust the viewing angle or adapt to display areas of different sizes, and can interact with the screen more directly, which improves the consistency and comfort of the user experience. Window 2 is adapted to the size of the display screen, making the product look neater and more unified. This design can give people a sense of coordination and consistency, enhance the visual appeal and quality of the product, and the center of the circle of window 2 coincides with that of the cover plate 3. The coincidence of the center of the circle of window 2 and the cover plate 3 can create a symmetrical beauty, making the product look neater and more beautiful. This symmetrical design can attract the user's eyeballs and improve the appearance quality of the product. The design of the coincidence of the center of the circle allows the user's line of sight to focus more naturally on the screen. The alignment of the center of the circle of window 2 and the cover plate 3 makes the user's visual focus more concentrated, which helps to improve the usability and user experience of the product. The coincidence of the center of the circle of window 2 and the cover plate 3 can simplify the design and manufacturing process. In the design stage, the position of window 2 can be more easily determined, thereby simplifying the complexity of layout and arrangement. In the manufacturing stage, it can also reduce the errors and adjustments that may occur in manufacturing.
