A liquid crystal display (LCD) comprising:
- an LCD panel;
- a timing control circuit comprising a plurality of reduced swing differential signaling (RSDS) output terminals;
- a plurality of data drivers connected to the LCD panel, each data driver being electrically connected to a respective RSDS output terminal of the timing control circuit via an independent conducting line;
- and
- a plurality of gate drivers connected to the LCD panel.
A timing control circuit used in a liquid crystal display (LCD) that has a plurality of data drivers, the timing control circuit comprising a number P (where P is a natural number) of reduced swing differential signaling (RSDS) output terminals each of which is electrically connected to a respective data driver via an independent conducting line, wherein a working frequency Xblack-inserting of the RSDS output terminals of the timing control circuit complies with the following formula:
