1Gbps/Iane Low Overhead Clock-Shared Differential Signaling (CSDS) - An Efficient Interface for Large-Size TFT-LCDs

摘要

A clock-shared differential signaling (CSDS) scheme is newly proposed to support high resolution and large-size TFT-LCDs with less than 3% overheads compared with transmitted data. CSDS adopts single-level, multi-dropped differential clocks which is shared among source driver ICs (CDs) and point-to-point connection for data lines. The protocol supporting CSDS makes the overhead of data transmission to be less than a few percent, which makes CSDS superior to other interfaces in terms of signal integrity, EMI, simple transmitter, and etc. It also supports flexible CD controls via just changing register values which are delivered by its protocol. And it is proved that CSDS supports 1.1Gbps per lane, which can cover next generation panels such as UD class.
