Abstract: A timing controller and an anti-interference method thereof are provided. The timing controller includes a timing control circuit. The timing control circuit provides an input signal for controlling a source driver. When at least one of the timing control circuit and the source driver detects that an interference event occurs to the input signal, the timing control circuit is configured to adjust a frequency of a data signal or a clock signal from a normal operation frequency to at least one anti-interference frequency. The timing control signal is further configured to provide at least one of the data signal and the clock signal to the source driver.

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.

Abstract: A control method, suitable for a display panel including M scan lines and a plurality of source lines, include following operations. M is a positive integer. M gate signals are generated sequentially in M time periods during a first display frame to the M scan lines of the display panel. A level of a data signal to one of the source lines is updated in the M time periods during the first display frame. N gate signals are generated in N time periods selected from the M time periods during a second display frame to N scan lines selected from the M scan lines. (M-N) gate signals are suspended during the second display frame. The level of the data signal is updated in the N time periods and is not updated in the (M-N) time periods during the second display frame. N is a positive integer smaller than M.
