PRELIMINARY DATASHEET
HOW THE RANGEMAX WORKS (CONTINUED)
DUAL DIMMING CAPABILITY
As seen in the Brightness vs. Time graphs, the boost mode
operation can improve the performance of cold cathode
florescent lamps in any LCD application by reducing the time it
takes to warm up lamps to their optimum operating
temperature. This feature is helpful in large LCD multi-lamp
monitors as well as automotive or industrial extreme
temperature applications.
The “boost” control provides a timed overdrive mode to
maximize light output over temperature. After a panel is
characterized with a profile of the user’s application (such as
desired light output as a function of ambient light and
temperature), the appropriate boost level, and duration of the
boost can be set. Further wide range dimming control is
provided by the Brite input dimming function.
