Claim 0:
1. A driving controller comprising:
a controller which receives an image signal and a control signal, and outputs a data control signal and a scan control signal,
wherein the controller which
divides a display panel into a first display region, a second display region and a boundary region,
outputs data control signal and the scan control signal to drive the first display region at a first driving frequency, to drive the second display region at a second driving frequency lower than the first driving frequency and to drive the boundary region at a plurality of third driving frequencies during a multi-frequency mode, and
sets the plurality of third driving frequencies respectively corresponding to a plurality of horizontal lines in the boundary region during the multi-frequency mode,
wherein the plurality of third driving frequencies corresponding to the plurality of horizontal lines have different frequency levels,
wherein the boundary region is defined between the first display region and the second display region,
wherein the boundary region includes H horizontal lines including a first horizontal line to an H-th horizontal line sequentially arranged from a position adjacent to the first display region, wherein H is a natural number, and
wherein the controller drives or masks each of the H horizontal lines every A frames during the multi-frequency mode, wherein A is a natural number.
