Abstract
A control IC (integrated circuit) for color sequential liquid crystal displays (LCD) is revealed. The control IC includes an interface for receiving a command and at least one display data and a timing generator to generate a scan timing signal, a data timing signal, and a driving timing signal. According to the scan timing signal, a scan driving circuit generates a scan signal that is sent to the color sequential LCD. In accordance with the data timing signal, a data driving circuit receives the display data for generating a data signal sent to the color sequential LCD. According to the driving timing signal, a light-source driving circuit generates a plurality of driving signals sent to the color sequential LCD so as to generate a plurality of color backlights. In accordance with the scan signal, the data signal and the plurality of backlights, the color sequential LCD displays a frame.
