Abstract

fetched live from OpenAlex

A simplified trilayer green phosphorescent organic light emitting diode with high efficiency and an ultralow efficiency roll-off has been demonstrated. In particular, the external quantum efficiency drops <1% from 100 to 5,000 cd/m2 and remains as high as ∼21.9% at 10,000 cd/m2. The power efficiency is also significantly improved, reaching 78.0 lm/W at 100 cd/m2, 50.5 lm/W at 5,000 cd/m2, and 42.8 lm/W at 10,000 cd/m2. The working mechanism of this simple device structure with an unprecedented high efficiency is also discussed.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
