43.3: Distinguished Paper: An Advanced Intra‐Panel Interface (AiPi) with Clock Embedded Multi‐Level Point‐to‐Point Differential Signaling for Large‐Sized TFT‐LCD Applications

In this paper, we present the newly developed intra-panel interface targeting to replace conventional multi-drop bus architecture with point-to-point differential interface. The multi-level signaling scheme is adopted to remove separate clock and control signal lines by embedding clock information into multi-level signal. The clock embedding scheme removes the skew problem found in previously announced intra-panel interface, and provides lower EMI. The simple multi-level signal detector is used to regenerate the clock signal from the data stream and does not require any sophisticated clock recovery unit in the receiver. The AiPi can be an effective solution to large size TFT LCD applications due to the reduced signal lines, lower EMI, and lower power consumption.
