    Abstract: An image display apparatus is disclosed. The image display apparatus includes a panel configured to display an image, a backlight including a plurality of light sources configured to output light to the panel, a light source driver configured to drive the plurality of light sources, and a processor configured to control the light source driver, wherein the processor changes the turn on duty of a light source corresponding to a moving object area in an input image and changes the level of current flowing in the light source. Consequently, the definition and luminance of an image including a moving object may be improved.

    Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate an source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.
