9.3: WhisperBus™: An Advanced Interconnect Link For TFT Column Driver Data

Increasing video data rates to liquid crystal displays brought about by increasing display format sizes and increased grayscale content are placing very high demands on digital data busses. These higher data rates coupled with constraints on EMI levels, size, power and component count are rendering CMOS data busses inadequate for the connection between the timing controller and the column drivers. The operation and performance of a comprehensive solution using a current signaling method (WhisperBus™) is presented.
