  • Patent number: 9813070
    Abstract: The present invention relates to a method for generating a reference signal to drive a display apparatus. A method according to the present invention may comprise generating a reference signal having a training pattern being repeated with a periodicity of two clock terms (CTs); and transmitting the reference signal to a phase locked loop (PLL). Each CT has a single embedded clock bit (CB) and a plurality of data bits, and the reference signal has a rising edge at a start point of a first CB corresponding to a first unit interval (UI) of a first CT, and a rising edge at an end point of a second CB corresponding to a first UI of a second CT. According to exemplary embodiments of the present disclosure, energy consumption and EMI effects can be remarkably reduced, and a complexity of PLL can be reduced.
