Note: 1. The pin no 9 is an option pin for DISM or LG format. ( LG Format = "GND" / DISM Format ="VCC")
Please refer to page 9 and 10 for further details
2. The pin no 10 is an option pin for DCR Function ( Enable = "VCC" / Disable ="GND")
3. The pin no 30 is LCD Test option.
LCM operates "AGP" (Auto Generation Pattern) or "NSB" (No Signal Black) is case that LVDS signals
are out of frequency or abnormal condition in spite of 12 volt power supply.
LPL recommends "NSB". ( AGP : "VCC" or "OPEN" / NSB : "GND" )
4. All GND (ground) pins should be connected together, which should be also connected to the LCD
module's metal frame.
5. All V (power input) pins should be connected together.
