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.
Claims33
A dithering method, comprising:
- performing the temporal/spatial compensation on input data;

A dithering apparatus, comprising:
- a compensation sector configured to perform the temporal/spatial compensation according to a gray level of input data and output dithering data by adding a head bit to the data on which the temporal/spatial compensation is performed;
- a gamma voltage generating sector configured to generate a plurality of main gamma voltages and a dummy gamma voltage;
- and
- a gamma voltage selecting sector configured to select the main gamma voltages or the dummy gamma voltage according to the dithering data.
