Detecting short connections in a plurality of led channels

A method for detecting one or more short connections in a plurality of light-emitting diode (LED) channels, wherein the method comprises:

• controlling, by processing circuitry, a plurality of driving devices in order to cause a pair of LED channels of the plurality of LED channels to operate in a first state during a first period of time and operate in a second state during a second period of time;
• comparing, by the processing circuitry, a first electrical signal corresponding to the first state of the pair of LED channels and a second electrical signal corresponding to the second state of the pair of LED channels;
• and
• determining, by the processing circuitry based on the comparison of the first electrical signal and the second electrical signal, if a short connection exists between the pair of LED channels.

A system comprising:

• a plurality of light-emitting diode (LED) channels;
• and
• a circuit for detecting one or more short connections in the plurality of LED channels, wherein the circuit comprises processing circuitry configured to:
• control a plurality of driving devices in order to cause a pair of LED channels of the plurality of LED channels to operate in a first state during a first period of time and operate in a second state during a second period of time;
• compare a first electrical signal corresponding to the first state of the pair of LED channels and a second electrical signal corresponding to the second state of the pair of LED channels;
• and
• determine, based on the comparison of the first electrical signal and the second electrical signal, if a short connection exists between the pair of LED channels.
