Description
Blue Background White Character LCDs
Have an appearance of white / gray letters against a blue background. These are good choices but for projects that will be used primarily indoors, as good contrast and readability depends on illumination from the backlight.
Gray Background Blue Character LCDs
Gray displays are transflective products that work equally well in daylight, or indoors in darker environments lit by the backlight. So these displays are more universal displays appropriate for products / projects that may be used either indoors or in more brightly lit situations outside.
5 volt displays
5 volt displays are appropriate for use with the LCD the LCD117 serial LCD driver board as well as other 5 volt microcontrollers.
3.3 volt displays
3.3 volt displays are compatible with the JeeLabs LCD Plug, as well as other 5 volt microcontrollers. That that the backlights only, on 3.3volt LCDs may be driven at 5 volts for brighter backlights.
