Abstract: A timing controller and an operation method thereof are provided. The timing controller includes a transmitter circuit and a control circuit. The control circuit ends a normal mode to enter a swing boost mode when a lock signal fed back by a source driving circuit indicates that quality of data signal is deteriorated in the normal mode. In the swing boost mode, the control circuit controls the transmitter circuit to boost the swing of the data signal from a normal level to a high level. The control circuit ends the swing boost mode and enters a clock training mode when the source driving circuit causes loss of lock to the data signal in the swing boost mode. In the clock training mode, the control circuit controls the transmitter circuit to employ a clock training data string as the data signal to transmit to the source driving circuit.

Abstract: An integrated circuit (IC), a display device and an anti-interference method thereof are provided. The IC includes an input pad, a source driving circuit and an anti-interference circuit. The input pad receives an input signal comprising image data from the external. The source driving circuit is coupled to the input pad to receive the input signal. The anti-interference circuit is coupled to the input pad to provide a variable capacitance. The anti-interference circuit adjusts the variable capacitance from a normal capacitance value to at least one anti-interference capacitance value when an interference event occurs to the input signal. The anti-interference circuit maintains the variable capacitance at the normal capacitance value when the interference event does not occur.

Abstract: A source driver of a display system includes a plurality of channels, and each of the plurality of channels includes a first latch, a second latch, an output driver and a comparator. The first latch receives a first data code and a second data code from a timing controller of the display system. The second latch receives the first data code from the first latch. The output driver is used for transmitting the first data code to a display panel of the display system. The comparator, coupled to the first latch, the second latch and the output driver, is used for comparing the first data code stored in the second latch with the second data code stored in the first latch, to generate a signal indicating a power level for the output driver to transmit the second data code.
