Abstract: A display apparatus in one example can include a plurality of light emitting diodes, and a plurality of driving devices to output driving signals for driving the plurality of light emitting diodes. Each of the plurality of driving devices bypasses input common command data and outputs the common command data to an adjacent driving device. Accordingly, a transmission period of data transmitted to the plurality of driving devices can be reduced.
