two suppliers for this LCD: Seiko Epson and Philips. The LCD module includes the LCD
glass, the LCD COG-driver, an elastomer connector and a metal frame. The LCD module is
included in the lightguide assembly module.

The LCD has an internal voltage booster and a booster capacitor is required between
Vout and GND.
Pin 3 (Vss9) is the LCD driver’s ground and Pin 9 (GND) is used to ground the metal
frame.
