초록
As a first demonstration of proven stability for a-Si, over 7000h of stability data for a high drive current a-Si AMOLED pixel driver circuit was presented at SID 2004. Also demonstrated was an AMOLED display operating at 6V using the IGNIS 4-T pixel driver circuit [1] and based on a top-emission reverse OLED architecture. In this paper, an update to that information is presented with test data that is representative of lifetime in excess of 25,000 hours taking into account pertinent acceleration factors, extracted from high current drive and high temperature stressing conditions. Lifetimes will continue to increase, given the high and ever-increasing OLED efficiency.
