Abstract:
1. A display device, comprising: a frame generating unit configured to receive an input frame comprising m-bit image data, wherein m is a natural number, to divide the image data into n different image data for each viewpoint, wherein n is a natural number greater than or equal to 2, and to generate an output frame comprising a plurality of 3-dimensional image data comprising the n different image data for each viewpoint; a gradation converting unit configured to perform a dithering operation to the output frame using a dither matrix comprising a plurality of (m-l)-bit critical values which are divided into k groups, wherein k is a natural number greater than or equal to 4, and the division is performed by one-to-one correspondence with k numbers of the 3-dimensional image data so that each of the image data for each viewpoint expresses m-bit gradation with l bits, wherein l is a natural number smaller than m, and to output the dithered image data for each viewpoint as output image signals; a data driving unit configured to generate a data driving voltage signal based on the output image signals received from the gradation converting unit; and a display panel configured to display an image in response to receiving the data driving voltage signal from the data driving unit.
