It is a special circuit board designed and manufactured for flexible display devices. FDC circuit board uses flexible substrates, such as polyester film or polyimide film, which has high flexibility and bending properties and can adapt to complex bending and curving shapes. FDC circuit boards are often used for flexible display components in electronic products, such as flexible display screens, flexible electronic tags, etc. Compared with traditional rigid circuit boards, FDC circuit boards can better adapt to curved or bent shape requirements, and are more flexible in devices with large space constraints, making FDC circuit boards widely used in wearable devices, smart phones, tablets, and automotive display systems.
