Lowering Power Consumption for Organic Light-Emitting Diodes Full-Screen Display

Abstract

Power consumption is one of the most important performances for organic light-emitting diodes (OLEDs) smart phones, especially in full-screen display era. But less research work was presented to optimize this item systematically. In this paper, we described the main influence factors which determine the power consumption of OLEDs full-screen display with a longer aspect ratio compared with the conventional display. The key factors from display part and driving IC part were discussed, and the efficient reduction for power consumption was presented via elimination of redundant voltage. Moreover, a simulation method considering different application scenarios was discussed, which also offered design approaches for lowering actual power consumption and obtained a 16.9% optimized data than that of the always on mode.
