Abstract
In this paper, a new signaling scheme is proposed for intra-panel interface using three transmission lines for flat panel displays. The interface utilizes multi-level current signaling with delta-y configured resistor network. It increases the number of symbols and differentiates the symbols with pseudo differential signaling. The interface utilizes input buffer with low input impedance to reduce driving current. Therefore, the interface has lower frequency with low driving current when it has same data rate as conventional intra-panel interface. As a result, electromagnetic interference can be lowered. The interface is fabricated using a 0.18um CMOS technology, and its measured bit error rate was 3.9 × 10-11.
