Shortening Time of Life-Time Evaluation for QD-OLED Through Low Gray Observation Condition

• Hee Kwang Song

Description:

Durable material causes long evaluation time. Accelerated evaluation has been used to shorten time until now. Extremely high brightness evaluation makes unnecessary noise such as pixel shrinkage. To solve the problem we found low observation gray shows decay shape of QD-OLED faster. Also decay shape was quite similar among different observation grays except very low observation grays. In this paper we introduce method which we could reduce evaluation time.
