Claim 2:
3. The display device according to claim 1,
wherein the control circuit includes:
a shift register circuit configured to serially output selection signals to select pixel rows one by one from the plurality of pixels;
a timing controller;
a trimming controller; and
a trimming width calculator,

wherein a pulse width of the selection signals defines a length of the threshold compensation period in a selected pixel row,
wherein the timing controller is configured to output a start pulse signal having a fixed pulse width,
wherein the trimming width calculator is configured to determine a trimming width based on the statistic,
wherein the trimming controller is configured to trim the pulse width of the start pulse signal output from the timing controller by the trimming width, and
wherein the shift register circuit is configured to output the selection signals having a pulse width equal to the trimmed pulse width.
