Figure 15. Registers x02 and x03 Lux Limit Controls
There is a simulated screen backlight dimmer represented by a rectangle, shown in
. This
rectangle changes from black, through 254 shades of grey, to white depending on the value of lux
measured by the OPT3004. It shows a brighter backlight for high-lux situations and a dim backlight for
low-lux situations. The low limit (darkest backlight) is always 0, and the high limit (brightest backlight) can
be adjusted with the
Lux for White
numeric field.
