More Information
Summary:A display device, including: pixels coupled to scan lines and data lines; a data driver configured to supply respective data signals to the data lines, including an amplifier disposed at an output terminal of the data driver, the amplifier including a first power terminal and a second power terminal; a switch unit configured to perform a power switching operation of alternately connecting the first power terminal and the second power terminal of the amplifier to a first driving power source and a second driving power source; and a driving controller configured to control the data driver and the switch unit, wherein the driving controller is configured to output a switch control signal to control the switch unit and interrupt the power switching operation during a blank period between source output periods, during which the data driver is configured to output the data signals of each frame.
