The present disclosure describes devices, components, connectors, and cables that provide backlight for a display screen. Some embodiments describe a light-emitting diode (LED) bar or a plurality of LED bars. The LED bars can include a communications port on a first end of each LED bar that is configured to receive a driving voltage, data signals, and/or some combination of power and data from a control source. The LED bars can include a power port on a second end of each LED bar that is configured to receive power from a power source. The light bars can be arranged substantially parallel to one another and in a matching orientation.
