1. A display apparatus comprising:
a display panel including a display region that includes a first display area and a second display area;
a data driver configured to provide a data voltage to the display region;
a gate driver configured to provide a compensation gate signal and an initialization gate signal to the display region, the gate driver including a first stage and a second stage; and
a driving controller configured to control the gate driver and the data driver,
wherein the driving controller is configured to determine a first driving frequency for the first display area and a second driving frequency for the second display area,
wherein the first and second stages are each configured to receive an input signal having a pulse-on state and a pulse-off state; and
wherein the second stage is configured to provide the compensation gate signal having a pulse duration shorter than a pulse duration of the compensation gate signal provided to the display region by the first stage when the first and second stages both receive the pulse-off state.
