Abstract: In a display apparatus, a display panel is divided into dimming areas and a backlight device includes light source blocks providing light to the dimming areas. Average gray-scale values and maximum gray-scale values respectively corresponding to the dimming areas are generated based on image signals provided to the dimming areas. Whether the average gray-scale values and the maximum gray-scale values are respectively within first and second reference ranges are checked. One of at least two parameters is selected according to a checked result, and representative brightness values respectively corresponding to the dimming areas are determined using the selected parameter. Duty ratios of the light source blocks are controlled based on the representative brightness values. As a result, power consumption is reduced when applying a dimming device to the display apparatus.

Abstract: A display apparatus includes a shutter panel and a display panel that alternately displays a left-eye image and a right-eye image in a 3D mode. The shutter panel includes dual-frequency liquid crystals in which a polarity of dielectric constant anisotropy is changed according to a frequency of the driving voltage to selectively delay a phase of the left-eye image or the right-eye image, which pass through the dual-frequency liquid crystals. The dual-frequency liquid crystals have a fast response speed to the low voltage, and thus a cross-talk phenomenon between the left-eye image and the right-eye image may be prevented.
