FLEXIBLE PRINTED CIRCUIT BOARD OF LARGE CAPACITY SIGNAL TRANSMISSION MEDIUM

摘要

A flexible printed circuit board of a large capacity signal transmission medium is provided to maintain signal transmission quality by keeping up impedance suitable for large signal transmission such as LVDS(Low-Voltage Differential Signaling). In a flexible printed circuit board of a large capacity signal transmission medium, a first pad(312), a second pad(314) are arranged on a copper signal layer alternately. A first pad has a positive phase and a second pad has a negative phase. The copper signal layer transmits the large signal from TV main board to a display. A copper grounding layer(320) grounds the large signal from the display. An insulating layer insulates the copper large signal layer and the copper grounding layer.
