The present invention discloses an eDP interface, including: a determination module, a clock signal generating module, a clock signal adjusting module, a first eDP data processing chip and a second eDP data processing chip. When the determination module determines that a target transmission rate is not equal to a protocol rate, the clock signal generating module generates a first clock signal and a second clock signal. The clock signal adjusting module adjusts the frequency of the second clock signal. The first and second eDP data processing chips process data according to the first and second clock signals, respectively.
