Abstract
Embodiments of the present disclosure relate to a display device and a driving method of the same. A display device according to embodiments of the present disclosure may include a comparison circuit for comparing the source driving voltage and a reference driving voltage and outputting a second control signal, and a discharge circuit for comparing the first control signal and the second control signal output from the comparison circuit and discharging the source driving voltage, thereby stably controlling a voltage.
Claims20
A display device comprising:
- a display panel on which a plurality of subpixels are disposed;
- a data driving circuit for driving the display panel;
- a power management integrated circuit for supplying a source driving voltage to the data driving circuit;
- a controller configured to output a first control signal through a first signal line;
- a comparison circuit configured to compare the source driving voltage and a reference driving voltage and output a second control signal through a second signal line based on the comparing the source driving voltage and the reference driving voltage;
- and
- a discharge circuit configured to form a discharge path for discharging the source driving voltage based on the first control signal and the second control signal.
