Abstract

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.

Dependent claims

A media device, comprising:

a display screen;
and
a backlight apparatus, comprising:
a first light-emitting diode (LED) bar comprising a first communications port disposed at a proximal end of the first LED bar and a first power port disposed at a distal end of the first LED bar, wherein the first LED bar further comprises a first integrated circuit (IC) control device disposed on the first LED bar;
a second LED bar disposed substantially parallel to the first LED bar, wherein the second LED bar comprises a second communications port disposed at a proximal end of the second LED bar and a second power port disposed at a distal end of the second LED bar, wherein the first LED bar and the second LED bar are disposed in a similar orientation and wherein the second LED bar further comprises a second IC control device disposed on the second LED bar;
a power cable coupled to the first power port and the second power port;
a communications cable coupled to the first communications port and the second communications port;
and
a control circuit board coupled to the communications cable.
