    While the controller for the display (ST7789S) Can work with a 1.8V system, the display will need 3.3V.
    Because of this you CAN  use 1.8V on the IOVDD and 1.8V Logic with the data lines (DB0-15, /CS, D/C, /WR, /RD, /RES, IM0)
    However you would need to apply 3.3V to the VDD for the LCD circuit. Is it possible for you to supply the +3.3V for the LCD alone?

    The logic voltage should be related to the IOVDD, i will make this correction on future spec upgrades.
