4. RELATION BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE
The 11 major points on the
γ
characteristic curve of the LCD panel are arbitrarily set by external power supplies V
0
through V
10
. If the display data is 00
H
or 3F
H
, gray scale voltage V
0
or V
10
is output. If the display data is in the range
01
H
to 3E
H
, the high-order 3 bits select an external powers pair V
n+1
, V
n
. The low-order 3 bits evenly divide the range
of V
n+1
to V
n
into eight segments by means of D/A conversion (however, the ranges from V
9
to V
8
and from V
2
to V
1
are divided into seven segments) to output a 64 gray scale voltage.
