Abstract
A channel detection device includes a disable circuit, LED pins, receivers and an error detection circuit. The disable circuit sends a disabling pulse to one or some LED pins of the plurality of LED pins, where the one or some LED pins are connected to the disable circuit. Each of the receivers is connected to one of the plurality of LED pins respectively and is capable of outputting an inhibiting signal when the LED pin connected receives the disabling pulse from the disable circuit. The error detection circuit is coupled to the receivers and the LED pins. The error detection circuit is configured to detect open-circuit of some LED pins of the plurality of LED pins, and bypass the detection of open-circuit of some other LED pin of which the receiver outputs the inhibiting signal.
