Note 1: The +12V power sources, which are designed to provide power

to back light inverter, is protected by 1.1A resetable fuse.

Note 2: LCD VEE is the power source for LCD logic circuit. The power

of 3.3V or 5V voltage is selectable by JP2 on main board. The

power ON/OFF is controlled by ENFPVEE signal. The power is

with over-current protection by resetable fuse.

Note 3: LCD VDD power source, which is controlled by the ENFPVDD

signal, comes from +3.3V. The power is with over-current

protection by resetable fuse. This power is for providing the

LCD bias voltage.
