Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including a plurality of scan lines, a plurality of pixels, and a plurality of readout lines;
a scan driver connected to the plurality of scan lines; and
a sensing circuit connected to the plurality of readout lines,
wherein each of the plurality of pixels comprises:
a light emitting element; and
a pixel circuit connected to the light emitting element at a first node,

wherein the pixel circuit drives the light emitting element in response to a corresponding driving scan signal among a plurality of driving scan signals during a display period,
wherein the pixel circuit is connected to a corresponding readout line among the plurality of readout lines at a second node,
the sensing circuit senses a potential of the first node through the corresponding readout line during a blank period,
each of a plurality of frames comprises the display period and the blank period,
the plurality of driving scan signals respectively comprise a plurality of rewriting periods,
at least one rewriting period of at least one driving scan signal among the plurality of driving scan signals is activated during the blank period, and
the plurality of rewriting periods have different durations from each other,
wherein the sensing circuit comprises:
an initialization circuit unit which initializes a potential of the second node during an initialization period in response to an initialization control signal,

wherein a time point at which each of the rewriting periods starts precedes a time point at which the initialization period corresponding thereto starts.
