ABSTRACT:
This invention discloses a flexible flat cable (FFC) which has a characteristic impedance (Z0) of 100Ω±5% and is used in a low voltage differential signaling (LVDS) signal transmission system for reducing the quantity of components of the LVDS signal transmission system and its costs, and the LVDS signal transmission system is a high-frequency signal transmission system between a liquid crystal display (LCD) interface and a system board interface, which comprises a low voltage differential signal (LVDS) receiver, a flexible flat cable (FFC) having an characteristic impedance (Z0) of 100Ω±5%, an accessory insert board, and a lift-up connector; wherein the LVDS receiver constitutes the signal transmission interface for the LCD and the lift-up connector constitutes the signal transmission interface for the system board interface, and one end of the flexible flat cable having the characteristic impedance (Z0) of 100Ω±5% together with the accessory insert board constitute a structure similar to an LVDS connector and electrically connects the LVDS connector, and the other end of the flexible flat cable with the characteristic impedance (Z0) of 100Ω±5% electrically connects the lift-up connector.
