Abstract
An electronic device may have a housing with a lid that rotates relative to a base. A display in the lid may have a thin-film transistor layer. Display driver circuitry may be mounted to the thin-film transistor layer. A display timing controller integrated circuit may be mounted in the base. A rigid flex printed circuit may have a rigid portion in the base to which the display timing controller integrated circuit is mounted and may have a rigid portion in the lid. A flexible printed circuit portion of the rigid flex printed circuit may be used to couple the rigid printed circuit portion in the lid to the thin-film transistor layer. A flexible printed circuit portion of the rigid flex printed circuit that extends between the lid and the base may be formed from a double-shield-layer single-signal-line-layer flexible printed circuit.
