TFT display screen is a display technology widely used in various electronic digital products, such as smartphones, tablet PCs, laptops and instrumentation displays. It can provide image quality with bright colors, high contrast and fast response time.TFT display is usually composed of several components, including glass substrate, driver IC, polarizer, backlight, and wiring.
Flexible Printed Circuit (FPC) is the bridge between the TFT screen and its control system, which is essential to ensure the proper functioning of the display.
Signal Transmission:
The FFC is used to connect the TFT screen to the motherboard or driver board, and is responsible for transmitting control signals and image data from the motherboard to the TFT screen. These signals contain information such as refresh rate, resolution, color depth, etc., and are the basis for realizing the screen display.
Customized connection:
According to different designs of electronic products motherboard connection, can change the TFT display wiring connection, interface type, bending form to be bent or folded to adapt to the compact design space.
Power supply:
In addition to signal transmission, the cable is also responsible for providing the necessary power support for the TFT display. This includes supplying power to the LED backlight module as well as providing operating voltage to the internal electronic components.
Structural dimensions:
Due to the flexible and flat nature of the row of wires, they allow the display module to be more compactly integrated inside the product and permit a certain degree of bending, which is important for applications that require special shapes or space constraints.
Reduced electromagnetic interference:
High-quality cabling design can effectively reduce electromagnetic interference (EMI) and ensure signal stability and integrity, thus improving display performance.
Material properties of the cable:
FPC wires need a certain degree of flexibility, the base material is made of calendered copper, this material is more resistant to bending, flexible. Polyimide (PI) copper foil is a common choice, it provides good flexibility and heat resistance.TFT panel ITO line line width mm, because some FPC is a TFT material quality is very critical components.
Conductivity is an important indicator of the ability of TFT materials to conduct current. Hongcai tft lcd display screen factory uses all high quality calendered copper materials, all of which have been tested for electrical properties, mechanical properties, temperature and humidity cycling, RoHS/REACH and other regulatory compliance, which in turn ensures the stability of the quality of the TFT displays we produce.
