Claim 12:
13. A method to modulate the current in a Light Emitting Element in function of N1 bits+N2 bits, the N2 bits having less weight than the N1 bits; the method comprising the steps:
for each of the N1 bits, the current in the light emitting element is controlled by said N1 bits, one bit at a time and during a time interval with a duration of at least TMin, and
for each of the N2 bits, the current in the light emitting element is controlled by said N2 bits, one bit at a time and during a first time interval that is less than TMin, and overriding said one of the N2 bits during a second time interval that is less than TMin, the sum of the duration of the first time interval and the second time interval being equal to TMin.
