Abstract
A display driving device includes a low-speed communication circuit configured to receive configuration data at a first data rate in a first mode; a high-speed communication circuit configured to train a communication clock signal for communication at a second data rate in a second mode, to receive image data and first control data using the communication clock signal in a third mode, and to receive second control data using the communication clock signal in a fourth mode; a control circuit configured to switch the first mode to the second mode upon completion of the first mode, to switch the second mode to the third mode upon completion of the second mode, to switch the third mode to the second mode when an abnormal state is detected in the third mode, and to switch the fourth mode to the first mode when an abnormal state is detected in the fourth mode; and a circuit configured to control pixels of a display panel to be driven according to the image data, thereby easily managing operation modes of a data driving device and a data processing device and minimizing a recovery time when an error occurs.
