Abstract
An organic light emitting display device comprising: a source device configured to output image data; and a sink device configured to perform a displaying operation based on the image data, wherein the source device is configured to change a frame rate of an image frame composing the image data while the displaying operation is performed, wherein the sink device is configured to change a frame rate of a panel driving frame for the displaying operation as the frame rate of the image frame is changed, and wherein the source device is configured to change the frame rate of the image frame while satisfying a condition in which an emission duty ratio of the panel driving frame is not changed.
Claims14
An electronic device comprising:
- a source device configured to output image data;
- and
- a sink device configured to perform a displaying operation based on the image data, the sink device comprising a display panel including a pixel circuit that includes a light emitting element configured to emit light in response to an emission on-off clock and a display panel driving circuit configured to drive the display panel,
- wherein the source device is configured to change a frame rate of an image frame composing the image data while the displaying operation is performed,
- wherein the sink device is configured to receive the image frame, to change a frame rate of a panel driving frame in response to a change of the frame rate of the image frame, and to perform the displaying operation based on the image frame by applying the emission on-off clock to the panel driving frame,
- wherein the sink device is configured to perform the displaying operation during a first panel driving frame having a first frame rate and a second panel driving frame following the first panel driving frame and having a second frame rate that is different from the first frame rate, each of the first and second panel driving frames including a plurality of off-periods of the emission on-off clock, and
- wherein an emission duty ratio of the first panel driving frame is equal to an emission duty ratio of the second panel driving frame even when a number of the off-periods included in the first panel driving frame is different from a number of the off-periods included in the second panel driving frame.
