Claim 11:
12. A driving controller comprising:
a controller which:
receives an image signal and a control signal,
divides a display panel into a first display area and a second display area during a multi-frequency mode, and
outputs a start signal for indicating a start of one frame and a masking signal for indicating a start of the second display area,
wherein the start signal comprises a first frame having a first duration and a second frame consecutive to the first frame having a second duration during the multi-frequency mode, the second duration is shorter than the first duration, and
wherein the start signal comprises a third frame having a third duration during a single-frequency mode, the first duration is longer than the third duration,
wherein the controller outputs image data signals corresponding to the first display area and the second display area during the first frame of the multi-frequency mode, and provides an image data signal corresponding to the first display area to a data driving circuit during the second frame of the multi-frequency mode.
