It depends what you want to do. Segment driven LCD panels are cheap, and 
low power, but very limited to characters you can create with the 
symbols provided. They suffice for clocks, time keeping and simple 
meters. Character LCD panels draw a little more current, but give you 
full character sets, and some programmable characters,  and are useful 
where you wish to displays lists or text messages. Grpahgics panels draw 
about the same current as character panels, but are much more expensive. 
They give you all the flexibility you might need to draw graphs, GUI 
interfaces, touch panels, etc, and you can go to colour panels which 
allow you to display juts about anything, including photographs. I never 
use the segment panels, I've never had a use for them, but they are 
cheap, and can be directly driven by the LCD peripheral on MSP430F4 
series micros. Character and graphics LCD panels can be driven by any 
MSP430 micro, but the more comples the display the more memory you'll 
need. If you decide to use  agraphics panel get one that operates at 3V3 
and which has built in power supply for Vo. I use Winstar alot

Hi,

I am trying to select a LCD for my project. I believe dot matrix LCD 
module is easier on the hardware side, but it  uses more power. On the 
hand, MSP430 provides the LCD driver. So use the LCD panel driven by 
MSP430 directly will save power.

Am I right?

Thanks.
