Claim 11:
12. A method to drive a driver circuit or a control circuit of a light emitting element in a display the method comprising the steps of:
transferring a control signal from a second storage element to a first storage element;
controlling the current in the light emitting element in function of said first control signal stored on a first storage element; and
loading the second storage element with a second control signal while the current in the light emitting element is controlled by the first control signal;
wherein the current in the light emitting element is modulated in function of N1 bits+N2 bits, the N2 bits having less weight than the N1 bits; and
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 further comprising 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.
