Abstract
The present disclosure provides methods for transmitting data in a display system, a clock controller, a source driver, and a display system. The method includes the steps of: receiving, by the clock controller, a reference clock signal and a data signal from an external data source; determining a phase difference between the data signal and the reference clock signal in each cycle; encoding the determined phase difference to generate a corresponding encoded signal; and transmitting the encoded signal and the reference clock signal to the source driver. By encoding the phase difference between the data signal and the reference clock signal in each cycle, it is able to use the encoded signal and the reference clock signal to transmit the data signal and the reference clock signal between the clock controller and the source driver.
