Thanks to all who replied.  

In my application, I would like to use a 4x20char LCD
with backlight.  Low power consumption is of primary
importance.  As I understand, LED backlit LCDs draw on
the order of 100mA at 5V.  My current plan is to use
EL backlighting, which might be slightly better
(although more complicated to implement).  Does anyone
have a better alternative?

Dear all:

I would like to use an electroluminescent (EL) LCD
because it boasts a very low current consumption (~2mA
I'm not sure if this is AC).  However, its lighting
power source requires AC100Vrms, 400Hz.  The
application that I'm working on can only use a 9V
battery and a 5V regulator.  

1) Is there some IC that can convert DC5V into
AC100Vrms, 400Hz?

2) The current probably will not be DC2mA will it?  If
not, what might it be?

Thanks in advance.
