Abstract
A driver circuit for driving at least one LED includes a data input for receiving set point data at a first data rate and at a first bit resolution, an LED output for driving the at least one LED with LED driving values at a second data rate and at a second bit resolution, and a processing device arranged for determining from the set point data by interpolation at least part of the LED driving values. The second data rate is higher than the first data rate, the processing device being arranged to interpolate in time.
