Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, and more specifically, to a liquid crystal display screen structure with a dual driving IC. Background Art

[0002] With the continuous progress of display technology and the increasing requirements of consumers for display effects, the liquid crystal display screen (LCD), as one of the mainstream display technologies, has been widely used in various electronic devices. While pursuing higher resolutions and larger display areas, how to optimize the design of the LCD module, improve the display performance, and reduce the production cost has become the focus of attention in the industry; in the traditional LCD module design, in order to meet the requirements of high resolutions and large-scale display dot matrices, usually one driving IC is bound at each end of the LCD. This design effectively improves the driving ability and display effect of the LCD by increasing the number of driving ICs, making the display picture more delicate and smooth. However, this design method also brings a series of technical challenges and limitations;

[0003] First of all, since FPCs need to be designed at both ends of the LCD to connect the driving ICs and the main board respectively, two corresponding connectors must be equipped on the main board to fix these FPCs. This not only increases the design complexity and space occupation of the main board, but also makes the layout of the entire display module more compact and complex. During the design process, factors such as the routing, length, and bending degree of the FPCs need to be carefully considered to ensure the stability and reliability of signal transmission; secondly, due to the existence of two FPC plug-in points, the number of plug-in operations in the production and assembly process also increases accordingly. This not only prolongs the production cycle, increases the production cost, but also increases the risks of poor contact and damage that may occur during the plug-in process. These potential problems not only affect the quality and stability of the product, but also may have an adverse impact on the user experience. Therefore, we make improvements in this regard and propose a liquid crystal display screen structure with a dual driving IC. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiments of the utility model is that the FPC used in the traditional dual-driving IC display screen requires the main board to be equipped with two connectors, and the number of plug-in operations increases, affecting the production cycle.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The mention of "embodiment" in this text means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of this utility model. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0027] As described in the background art, since it is necessary to design FPCs at both ends of the LCD to connect the driving IC and the main board respectively, two corresponding connectors must be provided on the main board to fix these FPCs. This not only increases the design complexity and space occupation of the main board, but also makes the layout of the entire display module more compact and complex. During the design process, factors such as the routing, length, and curvature of the FPCs need to be carefully considered to ensure the stability and reliability of signal transmission; secondly, due to the existence of two FPC plug-in points, the number of plug-in operations during the production and assembly process also increases accordingly. This not only prolongs the production cycle, increases the production cost, but also increases the risks of poor contact and damage that may occur during the plug-in process. These potential problems not only affect the quality and stability of the product, but may also have an adverse impact on the user experience.

[0031] The liquid crystal display screen structure of the dual-drive IC provided by the present utility model. In this application, by connecting the first FPC2 between the two second FPCs 201, the two second FPCs 201 can be combined together. Through the design of combining the two second FPCs 201, the two connectors originally required to be designed on the main board can be simplified into one, greatly simplifying the layout design of the main board, reducing the design complexity and space occupation. The combined FPC reduces the number of pluggings, from the original two pluggings to one, significantly improving the production and assembly efficiency, reducing the labor cost and time cost. By simplifying the design and improving the assembly efficiency, the production cost can be reduced to a certain extent, and the market competitiveness of the product can be improved.
