Bias levels
The bias levels for an MRA driving method with p = 8 are given in Fig.31 when G
max
and F have the same value. The
value p defines the number of rows which are simultaneously selected.
The row voltage F depends on the mux rate selected (number of rows N), the threshold voltage of the liquid (V
TH
), the
number of simultaneously selected rows (p) and the multiplexibility (m):
(1)
The column voltages are situated around the common level V
C
. The column voltage levels are equidistant from each
other. In Table 19 the column voltage levels are given as a function of F.
