Abstract
An organic light emitting display (OLED) apparatus including a power driver for applying a driving voltage to a display panel, a driver driving unit for applying a driving signal to the power driver, and a processor for applying a display data signal, which corresponds to a value of data displayed on the display panel, to the power driver. The power driver is configured to apply the driving voltage to the display panel when the driving signal and display data signal are each in an active state.
Claims18
An organic light emitting display apparatus comprising:
- a power driver configured to supply a driving voltage to a display panel;
- a driver driving unit configured to apply a driving signal to the power driver;
- and
- a processor configured to apply a display data signal to the power driver, the display data signal corresponding to a value of data to be displayed on the display panel,
- wherein the power driver is configured to supply the driving voltage to the display panel when the driving signal and the display data signal are both in an active state.
A method of operating an organic light emitting display apparatus comprising a power driver for a display panel, the method comprising:
- using a processor to generate a display data signal corresponding to a value of data to be displayed on the display panel, and to apply the display data signal to the power driver;
- using a driver driving unit to apply a driving signal to the power driver;
- and
- using the power driver to generate a driving voltage for the display panel according to the driving signal and the display data signal, wherein the power driver generates the driving voltage for the display panel when the driving signal and the display data signal are both in an active state.
A method of operating an organic light emitting display apparatus comprising a power driver for a display panel, the method comprising:
- using a processor to generate a driver control signal comprising display data to display on the display panel, and to apply the driver control signal to a driver driving unit;
- using the driver driving unit to apply a driving signal to the power driver according to the driver control signal;
- and
- using the power driver to receive the driving signal and to generate a driving voltage for the display panel,
- wherein the driver control signal comprises a dummy frame that is in a converting period after the driving signal is applied to the power driver and before the display data is in an active state.
