Abstract: An image display apparatus is disclosed. The image display apparatus includes a panel, a plurality of light sources to output light to the panel, a plurality of switching elements to switch the light sources, and a processor to control the switching elements, wherein the processor controls a current having a variable level to flow into each light source string among the light sources, based on local dimming data, thereby improving contrast in displaying images.

Abstract: An image display apparatus may include a panel, a backlight lamp to output light to the panel, and a drive controller to control current flowing in the backlight lamp. When a level of the current flowing in the backlight lamp during a first period is a first level, the drive controller controls the level of the current flowing in the backlight lamp during a second period (after the first period) to be a second level. A deviation of power consumption may be reduced.

Abstract: An image display device and a method for operating the same are disclosed. The method for operating the image display device including a plurality of backlight lamps arranged on upper and lower sides of a rear surface of a display panel includes receiving a 3-Dimensional (3D) image, alternately aligning a left-eye image and a right-eye image of the 3D image, and alternately displaying the aligned left- and right-eye images. In the displaying step, the backlight lamps arranged on the upper side of the panel and the backlight lamps arranged on the lower side of the panel are turned on in a portion of a period of the left-eye image or the right-eye image.
