Abstract:
1. A display device, comprising: a display unit including a plurality of pixels connected to a plurality of scan lines and a plurality of data lines; an inverse image processor to receive a first image data signal input from an external source and to generate a second image data signal based on the first image data signal; a controller to mix the first image data signal and the second image data signal alternately for each frame to generate a third image data signal, and to generate a driving control signal for opening and closing a pair of shutter spectacles for each image frame displayed in the display unit; and a data driver to receive the third image data signal from the controller and to apply a corresponding data voltage to each of the plurality of data lines, wherein: the inverse image processor performs a gray-inverting operation on the first image data signal to generate a gray-inverted image data signal, and performs a DC component adding operation on the gray-inverted image data signal to generate the second image data signal, wherein the DC component adding operation is selectively applied to a data signal corresponding to an edge portion of an object to be displayed.
