Abstract: Disclosed are an image display device and an image processing method thereof. A signal processing method of the image display device according to the present invention is a signal processing method of an image display device configured to receive an image having a varied vertical synchronization signal, including detecting an input synchronization signal using an input image clock, extracting an input vertical synchronization signal from the input synchronization signal, delaying the input vertical synchronization signal by a reference value of an output clock, continuously tracking a falling region of the delayed input vertical synchronization signal, and finally generating an output synchronization signal in which a vertical front porch is varied.

Abstract: The present invention relates to a display device and a method for image processing thereof, in which an input image is enlarged and a part of the enlarged image is selected as an image to be displayed on the screen of a display panel, and it is possible to thereby prevent screen burn-in and to prevent a phenomenon in which pixel data is not present and thus a pixel appears black when an image is moved on the screen.

Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device and the image display apparatus including the same according to an embodiment of the present disclosure includes: a first decoder to reconstruct image data received from an external electronic device, an encoder to compress the image data reconstructed in the first decoder, a memory to store the image data compressed in the encoder, and a second decoder to reconstruct the image data stored in the memory. Accordingly, despite of the increases of the amount of the input image data and the bandwidth thereof, the image data may be stored in the memory efficiently.
