Claim 5:
6. A non-transitory computer-readable storage medium storing program code for causing a data processing system to perform the steps comprising:
receiving as an input a dimming level setpoint signal;
establishing a selected duty cycle based on the dimming level setpoint signal;
utilizing rolling shutter to dingy the OLED display when the selected duty cycle is in a range from a first low limit to a duty cycle of 100 percent; and
utilizing global shutter to dim the OLED display when the selected duty cycle is in a range from a second low limit to a minimum duty cycle for the OLED display, wherein the first low limit is used to switch from rolling shutter to global shutter when the selected duty cycle is decreasing, the second low limit is used to switch from global shutter to rolling shutter when the selected duty cycle is increasing, the first w limit is less than the second low limit and both the first low limit and the second low limit are less than a blanking time for the OLED display.
