Operating LCD logic from 3.3V possible?

Are there any objections supplying the LCD logic with 3.3V instead of the 3V the LCD datasheet states? The Silabs Controller Manual says 2.4 to 3.3V is OK.

Anyone here running such a setup?

Most micros nowadays use 3.3V and I would like to avoid another voltage in the system.

Hello,

You can run it at 3.3V as you have mentioned but you run the risk of voltage spikes damaging the display. If the voltage is above 3.3v we cannot warranty any damage as well.
