LG Electronics 640T-ZA EPI Interface mini-LVDS vs. EPI, HF mini-LVDS TCON, Comparison

EPI Interface (mini-LVDS vs. EPI)

Comparison

HF mini-LVDS

HF mini-		FHD (10bit)
LVDS	60Hz	120Hz	240Hz
No. of Signal	36	36	72
Connector	60pin	60pin	80pin
	(2ea)	(2ea)	(2ea)

-Difficult to upgrade bandwidth limit

-Multiple number of wires needed for higher bandwidth

EPI (Embedded clock P-to-P Interface)

What to change

LCM (T-con to S-Driver IC)

HF mini-LVDSTCON
	18	18
VCC	1

(FHD 120Hz)

		FHD (10bit)
EPI	60Hz	120Hz	240Hz
	960ch	960ch	720ch
No. of Signal	12	12	32
Connector	-	50 pin	70pin
		(2ea)	(2ea)

-Better reliability on common noise -No data skew. Better EMI margin
