Product Specification
LC370WX1
Liquid Crystal Display
3-2. Interface Connections
This LCD employs two kinds of interface connection, a 30-pin connector is used for the module electronics
and two 12-pin Connectors are used for the integral backlight system.
3-2-1. LCD Module
- LCD Connector(CN1) : FI-X30SSL-HF (Manufactured by JAE) or Equivalent
- Mating Connector : FI-X30C2L (Manufactured by JAE) or Equivalent

Note: 1. If the pin no. 9 is Ground, Interface format is “LG”, and if the pin no. 9 is Vcc(3.3V), Interface format
is “DISM”. See page 9 and 10.
2. This pin is pull down to the ground with 3kohm resistor in LCM.
If you want to enable DCR, contact this pin to VCC(3.3V) with 0ohm resister.
For more information, see FIG 5 in the appendix 1.
` 3. The pin no. 30 is necessary for LCD test.
When LVDS signals are abnormal operation more than 3-Vsync times and power 12V is supplied,
‘Open’ or ‘Vcc’ : LCD operate itself some test patterns.(AGP – Auto Generation Pattern)
‘Ground’ : LCD operate itself a black pattern. (NSB – No Signal Black)
LPL recommend ‘Ground’ for NSB.
4. All GND (ground) pins should be connected together, which should be also connected to the LCD
module’s metal frame.
5. All V
LCD
(power input) pins should be connected together.
6. Input Levels of LVDS signals are based on the IEA 664 Standard.
