Abstract
A method for improving the EMI performance of an LCD device is disclosed, adapting for a point-to-point transistor transistor logic interface of the LCD device. The disclosed method comprises the following steps: receiving a plurality of image data based on a data CLK signal; providing a first CLK signal and a second CLK signal to a plurality of source drivers by a timing controller, wherein the frequencies of the first CLK signal and the second CLK signal are smaller than the frequency of the data CLK signal, the phase of the first CLK signal is different from the phase of the second CLK signal; and the timing controller transmitting a plurality of first image data to the plurality of source drivers based on the first CLK signal, and the timing controller transmitting a plurality of second image data to the plurality of source drivers based on the second CLK signal.
