• Electronic Control Register Set
This command is used to set 6-bit data in the electronic volume register to allow the liquid crystal drive voltage V
enter one-state voltage value among 64-state voltage values.
After this command is entered and the electronic control register is set, the electronic control mode is reset.
When not using the electronic control function, set (1,0,0,0,0,0).
• Sequence of the electronic control register set
(19) Static Indicator (2-Byte Command)
This command controls the indicator display of the static drive system. The static indicator display is controlled only
using this command, and this command is independent of other display control commands.
The static indicator is used to connect the SYNC pin to one of its liquid crystal drive electrodes and the FRS pin to the
other. For the electrodes used for the static indicator, the pattern separated from the electrodes for dynamic drive are
recommended. When this pattern is too adjacent, the deterioration of liquid crystal and electrodes may be caused.
Since the static indicator ON command is a 2-byte command that is used together with the static indicator register set
command, always use both the commands consecutively. (The static indicator OFF command is a 1-byte command.)
