Abstract: A signal transmitter of the invention is coupled to a plurality of signal receivers by a bus, and is configured to transmit display data through the bus for displaying a line. The signal transmitter includes a first data sequence and a second data sequence. The first data sequence has an electronic characteristic of a first value and is transmitted to a first signal receiver of the signal receivers, and the second data sequence has the electronic characteristic of a second value to a second signal receiver of the signal receivers. Wherein, a first signal transmission path from the signal transmitter to the first signal receiver is shorter than a second signal transmission path from the signal transmitter to the second signal receiver, and the first value is larger than the second value.
