Interplay between ambient and exciton-induced degradation in organic light-emitting devices
Bibliographic record
Abstract
Organic light-emitting diode (OLED), albeit is currently used in consumer electronics, still faces challenge with its limited performance stability. The degradation mechanisms that limit the lifetime of OLEDs can generally be separated into two categories: ambient and intrinsic. Much research has been devoted to understanding thus limiting these degradation mechanisms. However, surprisingly, there has been little work on how ambient and intrinsic degradation affect each other. In this work, the interplay between the ambient and intrinsic (more specifically exciton-induced) degradation is studied by comparing the effects of four degradation schemes, namely, no ambient or exciton-induced, ambient only, exciton-induced only and ambient and exciton-induced degradation on device lifetime. The results show that there is no interplay between ambient and exciton-induced degradation. Furthermore, it is evident that no photo-oxidation is present during ambient and exciton-induced degradation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
