Patent ID: 7460603

Claim:
A signal interface, suitable for transmitting a data signal to a driving circuit, the signal interface comprising: at least a first circuit, comprising: a first register; at least a second circuit, comprising: a selector, for receiving the data signal; a second register, electrically connected to the selector; a receiver, electrically connected to the selector; and a third register, electrically connected to the receiver; and at least a data bus, electrically connected to the first register, the second register and the third register, the data bus transmitting the signal output from the first register, the second register and the third register to the driving circuit; wherein if the data signal is a first single-end signal, the first register and the selector receive the data signal, and the selector further transmits the data signal to the second register to make the data bus transmit the signal saved in the first register and the second register to the driving circuit, and if the data signal is a serial signal, the selector receives and transmits the data signal to the receiver to have the data signal transferred to a second single-end signal and transmitted to the third register and then output to the driving circuit via the data bus.
