Signal transmission method, related timing controller, source driver and display device

A signal transmission method applied to one of a plurality of receiving units of a source driver, the plurality of receiving units are in one-to-one correspondence with a plurality of transmitting units of a timing controller, each of the transmitting units comprising a first linear feedback shift register and each of the plurality of receiving units comprising a second linear feedback shift register, the method comprising:

• receiving a signal transmitted by a corresponding transmitting unit, wherein the signal is a scrambled signal obtained by scrambling a signal to be transmitted with the first linear feedback shift register of the corresponding transmitting unit, wherein each frame of the scrambled signal comprises at least one first identification signal sequentially arranged in time domain, wherein a number of the first identification signals in the scrambled signal is equal to a number of the first identification signals in the scrambled signals received by other receiving units in the plurality of receiving units, wherein the first identification signal is configured to indicate the first and second linear feedback shift registers are configured to perform a reset operation, and after each collective reset operation is completed, the receiving unit is configured to output a display signal to a display panel, the collective reset operation representing that all of the second linear feedback shift registers of the source driver perform reset operations indicated by the first identification signals in a same order;
• controlling the second linear feedback shift register in the receiving unit to perform the reset operation based on the received first identification signal;
• descrambling the scrambled signal to obtain a signal before scrambling;
• and
• outputting the display signal to the display panel based on the signal before scrambling after each collective reset operation is completed.
