The user can select eight specific LED brightness levels (Table
„Display Brightness“ (page 10)) by changing the peak current driv-
ing the LEDs. The peak current is varied by varying the ON time of
the row drivers. Note that data line 3 is low (logic 0).
If dimming is required with finer control between 12.5% brightness
and 0.0% brightness, data line 3 can be set high (logic 1). The
12.5% peak current is now the brightness reference (100%-E8) for
further dimming and as shown in Table “Display Brightness“
(page 10) eight levels of dimming are provided. For example the
hex code EC in Table “Display Brightness“ (page 10) will provide a
brightness level 29% lower than the 12.5% brightness level.

Table „Power Down“ (page 10), the display is set to 0% brightness.
When in the Power Down mode data may still be written into the
RAM. The display is reactivated by loading a new Brightness Level
