First, a word of warning on the ModdersHQ guide: It does not have a current limiting resistor for the backlight, and will most certainly damage the backlight of any LCD connected to it.

Lifetime will probably be limited by the backlights. Yellow/green, green and red have about 50,000 to 100,000 hour lifetimes (5-10 years). Blue & white are more like 10,000 hours (1 year) at full brightness. You can shorten the backlight's lifetime drastically if you do not have a current limiting resistor in place. Read and understand this thread before you continue:

The pots are used for contrast setting and backlight dimming. Take a look at this post:

It has some links to guides.
