Abstract
Disclosed is an LED driving circuit and a driving method thereof, an LED display system. The LED driving circuit includes a main input terminal, a backup input terminal, and an output terminal. The LED driving circuit receives a configuration signal and a data signal from a preceding LED driving circuit via the main input terminal, or from any of previous LED driving circuits via the backup input terminal. The LED driving circuit forwards the configuration signal and the data signal of the LED driving circuits that are cascaded after the current LED driving circuit to a next LED driving circuit and/or to a following LED driving circuit that is connected to the current LED driving circuit across the next LED driving circuit via the output terminal. The present disclosure can ensure normal operation of following circuits even in case of continuous damage of some circuits.
