EPI Interface (mini-LVDS vs. EPI)
HF mini-LVDS
HF mini-
LVDS
No. of Signal
Connector
-Difficult to upgrade bandwidth limit
-Multiple number of wires needed for higher bandwidth
EPI (Embedded clock P-to-P Interface)
EPI
No. of Signal
Connector
-Better reliability on common noise
-No data skew. Better EMI margin
-Lower cost ( Cable, Connector )
-Slim S-PCB design (14mm  10mm) helps slimmer TV
