9-94 2x20 Customer Display Interface
Set Low Power State On
Format
1B 06
Description
This state is used to reduce Retail Display power consumption and extend the life of the
Retail Display VFD. Power is removed from the display, but the Retail Display controller
is still fully operational and continues to accept commands. This command causes the
firmware to blank or turn off the Retail Display. Display data can be processed while the
display is in the Low Power State, but it does not appear until the Low Power State is
changed. The displayed characters are preserved so that upon leaving the Low Power
State, the display is restored. To leave the Low Power State, one of the other state
commands must be received. This is the default state for the Retail Display after power-
up.
