Abstract
A LED display system includes a display controller including an output port having a first output terminal and a second output terminal; a plurality of LED sets; and a plurality of driving circuits, coupled in series and coupled between the display controller and the plurality of LED sets, respectively. Each of the driving circuits includes a first signal-input terminal, a first signal-output terminal, a second signal-input terminal, and a second signal-output terminal, wherein the first signal-input terminal of a first one of the driving circuits is coupled to the first output terminal, the second signal-input terminal of the first one of the driving circuits is coupled to the second output terminal. The display controller asserts a transition period for switching the driving circuits from a first operation mode to a second operation mode by manipulating a first signal outputted to the driving circuits through the first output terminal.
