Abstract
Systems and methods for electronic displays to use reference voltages to control driving current of illuminators are provided. The reference voltages are used to reduce or eliminate cross talk in driving voltages among different illuminators and driving voltage variations from frame to frame. The transient performance of the driving current of the illuminator (e.g., the current rise/decline time, current overshoot issue, current settling time) may be improved by implementing the reference voltages.
