What is FPC of projected capacitive touch screens?

Hi everyone! Does anybody know how to connect a touch screen with device? Yes, it needs FPC, controller, USB or other cables. This is Shenzhen Xinlilai Touch Technology Co., Ltd., a source factory specializing in the research and production of touch screens, LCD screens, and displays. Today, Let's talk to you about a very critical but often overlooked "small component" in projected capacitive touch screens - the FPC (flexible circuit board).

As an important component of projected capacitive touch screens, ribbon cables are responsible for accurately converting every touch and slide of fingers on the screen into electrical signals, and quickly and stably transmitting them to the main control chip. The wiring of the touch screen is like human nerves, transmitting signals to the brain. Imagine that without this' nerve ', even the most sensitive touch screen would be' paralyzed'.
 

Cable laying plays an important role and plays a crucial role:
1. Signal transmission: The position information of all touch points relies on the precise internal circuit transmission of the ribbon cable. Unreasonable circuit design, poor material or poor shielding can all lead to signal interference, delay, and even malfunction, directly manifested as poor touch, jumping points, and chaotic points.
 

2. Connect the screen and motherboard: One end of the ribbon cable is firmly fixed on the ITO (indium tin oxide) film or glass of the touch screen, and the other end is connected to the device's motherboard. This connection must be extremely stable and reliable, any virtual soldering or poor contact will render the entire touch function ineffective.
 

3. Resilience to withstand "bending" tests: In many devices, especially flip covers, sliding covers, or devices that require internal wiring, ribbon cables often need to be bent. A high-quality cable must have excellent flexibility and bending resistance to ensure stable operation, without breakage or aging, even after thousands of bends during the equipment's lifecycle.
 

As the source factory of projected capacitive touch screens, Xinlilai Touch is well aware of the decisive impact of wiring on the overall screen quality. We strive for excellence in every step from material selection, precision etching process, to strict impedance control and bending resistance testing. Because we understand that this small cable carries the user's smooth operation experience every time.
