Abstract
The present invention provides a control circuit and a scanning method thereof, and can be applied to a color sequential liquid crystal display (LCD). The color sequential LCD produces a plurality of color backlights, receives a data signal, and receives a plurality of scanning signals produced by a scan driving circuit. The voltage levels of the plurality of scan signals corresponding to each of the color backlights are select levels alternately. When the voltage level of a scan signal in the plurality of scan signals is the select level, the voltage levels of the other scan signals in the plurality of scan signals are non-select levels. Because the voltage levels of the plurality of scan signals corresponding to each of the color backlights are select levels alternately to scan sequentially the same backlight, color-mixing effects on images can be reduced.
