- This multi-drop method has an advantage of using a timing controller regardless of the number of outputs according to the resolution, that is, the number of column drivers, but is generated at a point where the data differential signal and the clock differential signal are separately supplied to each column driver. Due to impedance mismatch, signal distortion caused by reflected waves occurs, electromagnetic interference (EMI) is increased, and operation speed is limited due to a large load applied to a clock differential signal.

Since the transmission of the multi-level signal consisting of a small level, it is not possible to minimize the level of the transmission signal and there is a problem that the reduction efficiency of the electromagnetic interference (EMI) is insignificant.
