40V is absolute max rating.

Typical is 15.5V / 80mA for decent lit screen.

But obviously a switch mode power supply LED driver chip that has dimmer
controls is needed to control brightness and that must be able to take
the battery voltage and convert it to supply 15.5V (17V max) @ 80mA to
light the display properly.
