Description

FPC structure, touch screen and terminal equipment for single-layer multi-touch screen

technical field

The invention relates to a touch screen device, in particular to an FPC structure for a single-layer multi-point touch screen, a touch screen with the FPC structure and a terminal device.

Background technique

At present, smart phones occupy the vast share of the mobile phone market by virtue of their powerful functional advantages. Touch screen is an indispensable human-computer interaction tool for smart phones, and its performance directly affects the actual experience of consumers. The cost of the touch screen also accounts for a large proportion of the cost of the mobile phone. In order to reduce the cost of the touch screen under the premise of ensuring the performance of the touch screen, major solution manufacturers have introduced single-layer multi-touch technology. Single-layer multi-touch technology, that is, there is only one layer of touch screen sensing layer (sensorfilm), and there is no need for bridging. Both Tx and Rx channels are made on the same side of the sensing layer, and the junction of the channels is etched by ITO (indium tin oxide). Go to the FPC (flexible circuit board), and connect it through copper traces on the FPC. This technology saves one of the two sensing layers in the traditional structure, saves the manufacturing process, improves the manufacturing yield, and thus reduces the cost. When the traditional touch screen is used for mobile phone structure design, the FPC bonding area of the touch screen is small, the wiring is less, and the requirements for the FPC area are small, and the structure of the mobile phone can also be easily satisfied. Area 3, bending area 7, and routing area 2. The component area 3 and the FPC routing area 2 are connected through the bending area 7. By bending the FPC, the component area can be bent and assembled on the structural parts of the whole machine. However, if a single-layer multi-touch screen is used for the structural design of the mobile phone, compared with the traditional touch screen structure, the FPC Bonding area and wiring of the single-layer multi-touch screen will increase a lot, and the wiring area and component area of the FPC are required to be larger than the traditional structure. , the traditional width of the bending area as shown in Figure 1 cannot meet the requirements, and the overall structure of the mobile phone cannot meet this design requirement.

Contents of the invention

The invention aims to solve the problem that the FPC structure of the touch screen cannot meet the space requirements when a single-layer multi-point touch screen structure is adopted.

To achieve the above object, the present invention adopts the following technical solutions:

An FPC structure for a single-layer multi-point touch screen, including a wiring area, a wiring area and a component area connected in sequence, the upper edge of the component area is lower than the upper edge of the touch screen glass cover, and the wiring area is distributed on the lower side and at least one side of the element area.

Preferably, the present invention can further adopt the following technical solutions:

The element area is located in the upper left area of the glass cover of the touch screen, and the wiring area is distributed on the lower side and the right side of the element area.

At least a part of the FPC structure is attached to the glass cover plate of the touch screen by double-sided adhesive tape.

The element area is attached to the glass cover plate of the touch screen by double-sided adhesive tape.

The FPC structure also includes an extension area extending beyond the upper edge of the touch screen glass cover and a joint area connected to an end of the extension area.

The FPC structure is an FPC structure used in a touch screen mobile phone.

To achieve the above object, the present invention also adopts the following technical solutions:

A single-layer multi-point touch screen includes the FPC structure.

The single-layer multi-touch screen is a touch screen for mobile phones.

A terminal device includes the single-layer multi-touch screen.

The terminal device is a mobile phone.

The beneficial technical effects of the present invention are:

The present invention cancels the bending area in the traditional FPC, and arranges the element area so that its upper edge is lower than the upper edge of the touch screen glass cover, that is, the element area does not bend to the back as in the traditional design during installation, but on the contrary. As a rule of thumb, it is set to be on the same plane as the wiring area connecting the element area. At the same time, the wiring area is distributed on the lower side and at least one side of the element area, such as its right side. In this way, the side and the lower side of the element area Both sides can be used for routing, and there are more routing paths than traditional bending areas, so there is no need to increase the size of the FPC routing area and component area. Since the size of the relevant area of the FPC can be controlled to be smaller, the present invention not only solves the problem of insufficient wiring space on the FPC when a single-layer multi-touch screen structure is adopted, meets the size requirements of its design structure, but also ensures the use of This design structure of the touch screen monomer and the reliability of the whole machine.
