Hello. Similar situation with another forum post, but i unfortunately don't have a pin-compatible 1/3 bias display to use. I would like to use the LCD_E to drive a 1/2 bias display. I've reached out to the manufacturer to see if this is ok, but i'm wondering if I could also do this by disabling the charge-pump and deriving the bias w/ external resistors, applying a short R13 to R23?
Thanks,
Scott
disable the charge-pump, driving the bias w/ external resistors, short R13 to R23 should be OK
Please check LCD mode setting according to 17.2.10~15 of UG slau445h. display affect need to be checked.
