These displays are straightforward to use and are a great way to provide a user interface on many projects where you need more info than simple LED indicators or 7-Segment displays can provide since these are full alphanumeric displays with 2 lines of 16 characters each.  For an interactive display, pairing this type of display with a rotary encoder to navigate and select menu items on the display can provide a very nice user interface.

LCD Display

The display is composed of a 16 character x 2 line LCD display with a blue backlight and white characters.  Each of the characters are composed of a 5 x 8 dot matrix for good character representation.

The backlight has a potentiometer for adjustment of the contrast of the display for best viewing.  If the potentiometer is turned too far in one direction or the other, the display will appear blank or solid squares will appear instead of characters.  If this happens, just fiddle with the adjustment until it gives the best display.

The backlight is not controllable and is ON when power is applied to the module.

Note:  The non-uniformity in the picture is due to the protective film covering the display playing a trick on the camera.  The display has nice uniformity.
