Hi,

You can bring out the contrast on this display by using the following commands:
Follower Control
Power/ICON Control/Contrast Set with Contrast Set

To modify these registers you do need to use the function set command, During this commands set the IS2 bit Low, and the IS1 bit High.
This will give you access to instruction table one, where you would be able to control the software of the display.
