Abstract
A speed doubling circuit receiving display data in one frame period and outputting field A display data and field B display data in one frame period. A field conversion circuit converts the field A display data to have a highest gray-scale if the display data has a high gray-scale, and converts the field B display data to have a lowest gray-scale if the display data has a low gray-scale. Between the speed doubling circuit and field conversion circuit, an emphasis circuit is disposed which emphasizes each of the field A display data and field B display data in accordance with the display data one frame period before and the display data in the present frame period.
