Abstract: The present invention relates to a touch panel with a discharging function, which comprises a scanning bus, a sensing bus, a control unit, and a discharging circuit. The scanning bus is used for scanning a touch frame. The sensing bus interleaves with the scanning bus, and senses at least a touched location on the touch frame. The control unit is coupled to the scanning bus and the sensing bus 20′ for controlling them. The discharging circuit is coupled to the sensing bus or/and the scanning bus, and is controlled by the control unit for releasing the charges at the touched location or/and on the relevant path between the touched location and the buses. Thereby, by using a discharging circuit for releasing charges on the parasitic capacitor, the parasitic capacitance effect is avoided. Hence, the sensing accuracy of the touch panel is increased.

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.
