RGB Recombination Zone Tuning to Improve Optical Characteristics of White Organic Light-Emitting Diodes
Bibliographic record
Abstract
White organic light emitting diodes (WOLEDs) were fabricated using blue, green and red emitting layers (EMLs). The device has a structure of ITO/NPB/EML/Alq3/Liq/Al. Here, to control the white color balance, the location of the blue EML in the WOLEDs was fixed and only the thickness of blue EML was changed while both thickness and position of the green and red EMLs were adjusted. When adjusting the thickness of blue EML, the occurrence area of recombination zone was changed to influence the green luminescence. When adjusting the location and thickness of red EML, it could be found that the current density is more sensitive to the location of red EML than its thickness. Furthermore, it was discovered that light was emitted due to the Förster energy transfer even if it was apart from the recombination zone. WOLEDs with a maximum luminance of 17,740 cd/m,2 an external quantum efficiency of 2.12% at 100 cd/m,2 CIE coordinates of (0.328,0.301) and a color temperature of 6,185 K were obtained.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
