Data-processing apparatus

摘要

A notebook PC has a main unit and a display unit. The main unit incorporates a power-supply circuit and a display control circuit. The display unit comprises an LCD panel and a backlight. The main unit and display unit are electrically connected by an LCD harness. The LCD harness extends through a hinge mechanism that couples the display unit to the main unit, allowing the display unit to rotate. The LCD harness comprises lines including power lines and signal lines. The power lines supply power from the power-supply circuit to the LCD panel and the backlight. The signal lines supply data from the display control circuit to the LCD panel. A ferrite core wraps only the signal lines.
