Display apparatus including driving devices that bypass input common command data, and image display apparatus including same

A display apparatus comprising:

• a plurality of light emitting diodes;
• and
• a plurality of driving devices to output driving signals for driving the plurality of light emitting diodes,
• wherein each of the plurality of driving devices bypasses input common command data and outputs the common command data to an adjacent driving device,
• wherein each of the plurality of driving devices includes:
• a first shift register to store command data among data input through a data input terminal, and
• a second shift register to store image data among the data input through the data input terminal, and
• wherein in case in which the common command data is input through the data input terminal, each of the plurality of driving devices outputs the common command data to an outside through a first path without passing through the first shift register, and stores the common command data in the first shift register through a second path.
