Product Specification (V1.1) 09.13.2005

(This specification is subject to change without further notice)

(2) Electronic Volume Register Set

By using this command to set six bits of data to the electronic volume register, the

LCD drive voltage V0 assumes one of the 64 voltage levels. When this command is

input, the electronic volume mode is released after the electronic volume register

has been set.

When the electronic volume function is not used, set D5 - D0 to 100000.

7.2.19 Static Indicator (Double Byte Command)

This command controls the static drive system indicator display. The static indicator

display is controlled by this command only, and is independent of other display control

commands. This is used when one of the static indicator LCD drive electrodes is

connected to the M terminal, and the other is connected to the FLM terminal. Different

patterns are recommended for the static indicator electrodes and for the dynamic drive

electrodes. If the patterns are too close, it can result in deterioration of the LCD and of

the electrodes.

The static indicator ON command is a double bytes command paired with the static

indicator register set command, and such commands must be executed one after the

other. (The static indicator OFF command is a single byte command)

(1) Static Indicator ON/OFF

When the static indicator ON command is executed, the static indicator register set

command is enabled, and no other command aside from the static indicator register

set command can be used. This mode is cleared when data is set in the register by

the static indicator register set command.
