When /DOFF = L, the column driver outputs (Yn) are all at the V1 level. Moreover, because the /DOUT output is

also L, the /DOFF’ signal of the row driver becomes L, causing all the row driver outputs (Xn) to also be at the V1

level. The display is therefore forcibly put in the off status, regardless of the display data.

Remark /DOFF’ is the row driver input pin.
