ABSTRACT:
The present invention provides a liquid-crystal display device that is able to reduce EMI, current consumption, and so forth in an interchip transfer of display data, a timing signal, and so forth and to provide an appropriate timing margin. In an interchip transfer of display data, a timing signal, and so forth that uses a plurality of data drivers, a certain data driver is used as a data driver. When the data driver is used in a first stage, an internal receiver is made to function as an RSDS receiver by fixing the IFM terminal at the “H” level. The received RSDS signal constitutes a CMOS signal that has been divided into two by the receiver and is output by the transmitter. Here, a data inversion signal is generated and output by the transmitter. When the data driver is used in the second or subsequent stage, the internal receiver is made to function as a CMOS receiver by fixing the IFM terminal at the “L” level. The received CMOS signal is output after being subjected to inversion control by means of the data inversion signal by the receiver and transmitter.
