Display device and driving apparatus thereof

A driving apparatus of a display device comprising a plurality of pixels arranged in a matrix comprising:

• a plurality of pixels arranged in a matrix;
• a signal controller adapted to convert input image data having a first frequency into a plurality of output image data having a second frequency and provide the plurality of output image data at an output;
• and
• a data driver having an input coupled to the output of the signal controller, the data driver being adapted to convert the output image data into analog data voltages application sequentially to the pixels,
• wherein, a luminance of the pixels is determined as a function of the analog data voltages, and further wherein
• the sum of an amount of light provided by a plurality of the output image data is the same as an amount of light provided by the input image data, and
• one of a plurality of the output image data having a smaller gray voltage when the input image data are lower than a predetermined gray voltage.
