Abstract
The present disclosure provides a light emitting display apparatus including a display panel displaying an image, a power supply supplying a driving voltage to the display panel, a data driver supplying a data voltage to the display panel, a timing controller controlling the power supply and the data driver, and a sensing circuit unit receiving a feedback component of the driving voltage as a feedback voltage and selectively sensing an electrically stabilized period in the feedback voltage based on an internal control signal of the power supply.
Claims12
A light emitting display apparatus comprising:
- a display panel displaying an image;
- a power supply supplying a driving voltage to the display panel;
- a data driver supplying a data voltage to the display panel;
- a timing controller controlling the power supply and the data driver;
- and
- a sensing circuit unit receiving a feedback component of the driving voltage as a feedback voltage and selectively sensing an electrically stabilized period in the feedback voltage based on an internal control signal of the power supply.
A driving method of a light emitting display apparatus, the driving method comprising:
- driving a power supply to output a driving voltage for driving a display panel;
- receiving a feedback component of the driving voltage as a feedback voltage and detecting a rising time of a control signal of the power supply;
- and
- sensing the feedback voltage after a certain delay time elapses from a rising time of the control signal, for selectively sensing an electrically stabilized period in the feedback voltage.
