1. A transceiver, comprising:
a transmitter which transmits frame data through a first interface during a frame period including a vertical back porch period, a vertical active period, a vertical front porch period, and a variable vertical front porch period; and
a receiver connected to the transmitter through the first interface and a second interface,
wherein the receiver transmits a start pulse of a synchronization signal to the transmitter through the second interface before starting transmission of the frame data,
wherein the transmitter transmits synchronization pulses of the synchronization signal to the receiver through the second interface during the variable vertical front porch period,
wherein the transmitter transmits a transition pattern of the synchronization signal instead of the synchronization pulses when a touch interrupt occurs during the variable vertical front porch period, and
wherein a transmission subject of the synchronization signal is switched from the transmitter to the receiver in response to the transition pattern.
