Abstract
A 3D-capable image display device includes: a display panel having a plurality of pixels and a plurality of data lines; a gamma reference voltages generator for generating a plurality of gamma reference voltages including positive gamma reference voltages and negative gamma reference voltages; a data lines driver for converting an image signal into corresponding data line drive voltages based on the plurality of gamma reference voltages; and a signal controller operating according to a mode selection signal including information for selecting one of different 3D driving methods, wherein when a gap between the positive gamma reference voltages and the negative gamma reference voltages is referred to as a black gap, and size of the black gap is variable based on the selected 3D driving method.
