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 is controlled by the UI SW and the control signals are from the UPP asic. The VIO
and Vflash1 regulators supply the LCD with power.
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.
