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. Josh
LCD Module or Panel?

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
