Driving circuit unit, display device including the same, and method of driving the same

A driving circuit unit driven in a first mode and a second mode, comprising:

• a driver configured to receive a driving voltage when driven in the first mode and does not receive the driving voltage when driven in the second mode;
• and
• a first storage unit disposed outside the driver and configured to receive and store driving data of the driver when changed from the first mode to the second mode,
• wherein a second storage unit in the driver receives the driving data from the first storage unit when changed from the second mode to the first mode.

A display device comprising:

• pixels connected to display scan lines, self-scan lines, emission control lines, and data lines;
• at least one display scan driver configured to supply a scan signal to the display scan lines during an active period of one frame;
• at least one self-scan driver configured to supply the scan signal to the self-scan lines during the active period and a blank period of the one frame;
• a data driver configured to supply a data signal to the data lines during the active period;
• an emission driver configured to supply an emission control signal to the emission control lines during the active period and the blank period;
• and
• a driving circuit unit configured to control the display scan driver, the self-scan driver, the data driver, and the emission driver,
• wherein the driving circuit unit comprises:
• a first driver configured to be driven during a display scan period included in the active period;
• a second driver configured to be driven during at least one self-scan period included in the blank period;
• a first switch connected between a driving power line to which driving power is supplied and the first driver, configured to be turned on in the active period and configured to be turned off in the blank period in response to control of a controller included in the second driver;
• and
• a first storage unit configured to receive and store driving data from the first driver before the first switch is turned off.

A method of driving a display device, the method comprising:

• generating output data and a display driving control signal using a first driver during an active period of one frame;
• generating a self-driving control signal using a second driver during a blank period of the one frame;
• storing driving data for driving the first driver in a first storage unit disposed outside the first driver after the active period;
• cutting off driving power supplied to the first driver during the blank period;
• and
• transferring the stored driving data from the first storage unit to a second storage unit in the first driver after the blank period.
