I have a HP32S II scientific calculater. Display of the same is very faint, would like to darken it.
Generally for LCD calculators there is no adjustment of the screen that you can do.
If it's dim and battery powered, try replacing the batteries. If it's solar powered, try keeping it in strong light
SOURCE: The display is coming very faint
Most probably the batteries since I just had the same exact problem and replaced them. Works like a charm now. Takes two batteries. A76R W82.

Press the [SHIFT][MODE] to access the (SETUP) screen. -See the screen capture below. Press [7:Sci] to select the output display format to be Scientific.
You will then be prompted to key in a number between 0 and 9 to choose the number of decimal digits.
If you do not want fractions nor radicals set the default Input/Output format to LineIO.
To do so press [SHIFT][MODE][2:LineIO]. After that perform the steps given above to select Scientific format for the output.
