Flexible circuit board ( FPC ) is widely used in smart phones, mainly reflected in the following aspects :
Display connection : Whether LCD, OLED or flexible AMOLED screens need to be connected via FPC. This flexible circuit can adapt to the bending requirements of the screen and ensure the stable transmission of signals and power.
Camera connection : Mobile phone cameras usually require FPC to connect to the motherboard to ensure that image data can be transmitted quickly. In addition, in order to achieve multi-camera function, FPC is also needed.
Touch screen induction circuit : Flexible FPC is used to realize the induction circuit of the touch screen, so that users can operate by touching the screen.
Battery connection : FPC is also used for the connection between the battery and the motherboard to ensure the stability and safety of battery power supply.
Antenna connection : In smartphones, the FPC helps to connect the antenna to ensure stable reception and transmission of signals.
Fingerprint module connection : With the development of smart phone technology, fingerprint unlocking has become a common function. FPC is used to connect the fingerprint module to achieve fast and accurate fingerprint recognition.
Key connection : the physical button or touch button on the smartphone may also be connected to the motherboard through the FPC to achieve the normal operation of the key function.
In addition, with the advent of 5G technology, FPC has been widely used in smart phones, especially in applications such as multi-cameras, under-screen fingerprint modules, RF antennas, folding screens, and flexible screens. The amount of FPC used in a single smartphone is also increasing to meet more complex and advanced functional requirements.
In general, due to its high flexibility and reliability, flexible circuit boards play a key role in the design and manufacture of smart phones, providing users with a richer and more convenient experience.
