Abstract
A method and a circuit component for suppressing crosstalk associated with the common voltage in a liquid crystal display are disclosed. In particular, in a liquid crystal display where the crosstalk is mainly caused by various control signals generated by a timing control circuit, one or more timing control signals are extracted from the timing control circuit and processed to become a compensation signal. The compensation signal is provided to display area of the liquid crystal display. The timing control signals generated by the timing control circuit include a start signal and a plurality of clock signals. The steps for processing these signals may include summing, inverting, high-pass filtering and amplitude adjustment, to be carried out in different orders and/or combinations. When the timing control signals are current signals, the steps for processing these signals may include current-to-voltage conversion, summing and inverting.
