Abstract
Description
Technical Field
[0001] This utility model relates to the field of CTP (capacitive touch screen) technology, and more specifically to a CTP touch screen with a housing. Background Technology
[0002] Existing CTP touchscreens typically involve bonding the Sensor FOG (Flexible Printed Circuit) to the cover plate through multiple processes, and then fixing it to the housing material using adhesive or double-sided tape. This process has the following drawbacks:
[0003] The production process is complex: the Sensor FOG and cover plate must be bonded together first, and then assembled into the shell, resulting in redundant processes.
[0004] Inefficient: Multiple bonding and curing steps extend the production cycle;
[0005] Higher costs: Additional materials (such as double-sided tape and glue) and labor increase costs. Utility Model Content
[0006] The main objective of this invention is to propose a CTP touchscreen with a shell, in order to solve the technical problems existing in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A CTP touch screen with a shell includes a main body and touch function components. The main body is integrally formed with a cover plate, and the outer side of the main body has a protruding structure.
[0009] The touch function component includes a Sensor FOG that is directly attached to the main display touch area for implementing touch functionality;
[0010] The Sensor FOG is electrically connected to an external circuit via an FPC;
[0011] The main body is fixedly connected to external equipment through a protruding structure.
[0012] In some embodiments, the side of the main body is also provided with a buckle to enhance the connection stability between the shell and the external device.
[0013] In some embodiments, the Sensor FOG is directly fixed to the display touch area of the body via an adhesive layer and matches the interface of the FPC.
[0014] In some embodiments, the integral molding of the body and the cover plate is performed using injection molding or in-mold inlay.
[0015] In some embodiments, the size and position of the protruding structure are matched with the corresponding interface of the external device to enable rapid assembly.
[0016] In some embodiments, the protruding structure is a mounting hole with a protrusion.
[0017] The advantages of this utility model compared with the prior art are:
[0018] Simplified process: The bonding step between the cover plate and the shell material is omitted, and the integration of the main body and the cover plate is completed directly through a one-piece molding process;
[0019] Cost reduction: Reduced consumption of materials such as glue and double-sided tape, and shorter production cycle;
[0020] Improved assembly efficiency: The mounting holes match the interfaces of external devices, and combined with snap-fit or protruding structures, rapid assembly is achieved;
[0021] Enhanced structural stability: One-piece molding process and mechanical locking design (such as snap-fit and protruding structures) improve overall reliability. Attached Figure Description

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0028] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0029] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.
[0030] The following will describe in detail, with reference to the accompanying drawings, a CTP touchscreen with a housing material according to an embodiment of this application. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.
[0031] Example 1:
[0032] See Figure 1-3 As shown, a CTP touchscreen with a housing includes: a main body and a touch function component; the touch function component includes a Sensor FOG directly attached to the display touch area of the main body for implementing touch function; the outer side of the main body has a protruding structure for forming a mechanical lock with an external device, typically the protruding structure being a mounting hole.
[0033] The main body 2 and the cover plate are integrally molded: the shell material and the cover plate are directly molded into a single part by injection molding or in-mold embedding process, eliminating the traditional bonding process;
[0034] Sensor FOG3 bonding: The Sensor FOG3 is directly fixed to the display touch area 1 of the main body 2 using optical adhesive (OCA) or hot pressing process, and is soldered to the FPC4 for conduction;
[0035] Mounting hole 5 for connection with external equipment: Mounting hole 5 is opened on the outer side of the main body 2, and is fixed to external equipment (such as display frame) by screws or clips.
[0036] Example 2
[0037] In another embodiment, a buckle 6 is added to the side of the main body 2 to connect with external equipment through a flexible snap-fit method, further simplifying the assembly steps.
[0038] By comparing traditional processes with this utility model:
[0039] Process reduction: The original 6 processes (Sensor cover plate application → cover plate adhesive application → shell bonding → curing → FPC welding → testing) have been reduced to 3 processes (integrated molding → direct sensor bonding → FPC welding).
[0040] Cost reduction: Material costs are reduced by approximately 20%, and labor costs are reduced by 30%;
[0041] Improved yield: Due to simplified processes, the defect rate decreased by 15%.
[0042] The above description is only a preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
