Internal resistor type bias generator configurations

If successive commands have been issued, the
command mode ID can be omitted. While the
system is operating in the non-successive com-
mand or the non-successive address data mode,
the CS pin should be set to 1 and the previous
operation mode will also be reset. The CS pin
returns to
0 , so a new operation mode ID
should be issued first.
Bias generator
The HT1647 bias voltage belong to internal re-
sistor type. It provides two kinds of bias option
named 1/5 bias and 1/4 bias respectively. It is
recommeaded to select 1/5 bias to fit TN-type,
STN-type LCDs and select 1/4 bias to fit
ECB-type LCDs. It also provides three kinds of
bias current option by programming to suitably
drive LCD panel. The three kinds of bias cur-
rent are large, middle, and small, respectively.
Usually, large panel LCD can be excellently dis-
played by large bias current. Relatively, it con-
sumeslargecurrentwhenLCDONcommandis
used. Small bias current provides low power
consumption during on condition when the
LCD is normally displayed. The following are
the reference value table.
