Abstract:
1. A display apparatus comprising: a driving circuit configured to receive an input image signal, convert the input image signal into a first data voltage and a second data voltage having different voltage levels from each other at a same gray scale in a two-dimensional (2D) mode, and convert the input image signal into a left-eye data voltage and a right-eye data voltage in a three-dimensional (3D) mode; a display panel comprising a plurality of pixels configured to display a plurality of colors, each pixel comprising at least one sub-pixel comprising a first sub-pixel electrode and a second sub-pixel electrode configured to display a same color, the first and second sub-pixel electrodes configured to respectively receive a different one of the first and second data voltages in the 2D mode to display a first image and respectively receive a different one of the left-eye data voltage and the right-eye data voltage in the 3D mode to display a second image comprising a left-eye image and a right-eye image; and a patterned retarder disposed on the display panel configured to transmit the first image or the second image and comprising at least one first retarder configured to provide a first directivity to the left-eye image and at least one second retarder configured to provide a second directivity different from the first directivity to the right-eye image, the first retarder being disposed corresponding to one of the first sub-pixel electrode and the second sub-pixel electrode and the second retarder being disposed corresponding to the other one of the first sub-pixel electrode and the second sub-pixel electrode, wherein: the first data voltage and the second data voltage have a same polarity; and the first data voltage has a voltage level based on a first gamma curve and the second data voltage has a voltage level based on a second gamma curve different from the first gamma curve over the entire grayscale range of the first and second gamma curves.
