Note
1.
Multiplex drive ratios of 1 : 3 and 1 : 4 with
1
2
bias are possible, but the discrimination contrast ratios are reduced;
for 1 : 3, D = 1.732 and for 1 : 4, D = 1.528. However, there is an advantage that leads to reduction of V
op
as follows:
a) for 1 : 3 multiplex (
1
2
bias), V
op
= 2.449

b) For 1 : 4 multiplex (
