The rear displays are located in the back of the driver and front passenger seats. The rear seatback display screens show video from the disc player.
The seatback displays receive power and ground from the vehicle harness. A discrete control circuit from the disc player is used to control the power state of the displays.
The displays receive all other video, audio, and control information via the Low Voltage Differential Signaling (LVDS) cable. The LVDS cable connected to the disc player contains two pairs of data circuits, one pair for each of the rear displays. A splitter cable is used to separate the data circuits to each individual display, providing separate information to each display.
