Abstract

The present invention relates to a display apparatus to synchronize a synchronous signal and an inverter driving signal in response to a display mode, and a control method thereof. A back light unit of the display apparatus makes a back light to dim based on an inverter driving signal, and a dimming frequency of the back light varies in response to a synchronous signal frequency of the image. When a synchronous signal having an abnormal frequency is inputted to the back light unit for several seconds, the back light unit holds the frequency of the inverter driving signal and the frequency of the inverter driving signal varies smoothly in response to the display mode.
