CONTRAST ADJUSTMENT
The contrast can be set by means of a command for all the displays in the EA DOG series. The contrast setting of the
display must be set once by the software, and is then kept constant throughout the entire operating temperature range
(-20..+70°C), thanks to the integrated temperature compensation.
