P‐39: The IR Drop Compensation Method of AMOLED Display for Dynamic Power Control

In this paper, a new compensation method to solve IR‐drop on AMOLED panel for using dynamic power setup. This paper discusses the dynamic power setup bring the different loading effect and representing the varied level of IR drop on AMOLED panel. If only compensate the IR drop in a fixed current driving condition, the IR drop of the other condition could be worse. In order to improve this problem, the proposed method reduces IR drop phenomenon due to the different power setup by using adjustable compensation ratio for different combination of power setup. Additionally, instead of by full band full tuning, the proposed compensation method is support scaling factors fine tuning for different combination of power & EM setting.
