Display apparatus and driving method thereof

A display apparatus comprising:

• a display panel configured to display an image;
• a gate driver configured to apply a gate signal to the display panel;
• a driving circuit including a signal generating circuit configured to generate a clock signal for driving the gate driver and a frequency generating circuit configured to generate an internal oscillator signal to allow the clock signal to be generated with an internally set frequency band;
• and
• a jitter correction circuit configured to correct a jitter of the clock signal, based on the internal oscillator signal and the clock signal fed back from the signal generating circuit,
• wherein the jitter correction circuit is configured to correct the jitter of the clock signal, and
• wherein the jitter correction circuit comprises:
• a jitter detection circuit configured to detect the jitter of the clock signal;
• a jitter selection circuit configured to generate a jitter selection value based on the jitter of the clock signal;
• a jitter integral circuit configured to accumulate and integrate the jitter selection value to generate an integral jitter value;
• and
• a jitter comparison circuit configured to compare the integral jitter value with the internal oscillator signal.
