Abstract
A dithering method prevents the gray level saturation in a gray level region having high luminance and expresses all gray levels. The dithering method includes performing the temporal/spatial compensation on input data, generating dithering data by adding a head bit to the data on which the temporal/spatial compensation is performed, and selecting a corresponding gamma voltage according to the dithering data.
