      @Daiki Do you have an extra LED driver for LCDs? You could take the connections from there. Kinda like in this picture:

          Maybe try a MOSFET to get 3.3V. However, I am not very confident that would work. I don’t understand why it didn’t work when you combined the pins 28 and 30 with 2 and 3.
          What happens when you only put 3.3V on pin 30, leaving 28 (VDD) disconnected? And what happens if you reverse it (28 = 3.3V, 30 = 0V)?

          Maybe somebody else with more experiences with LCDs could join the conversation?
