Near-planar light outcoupling structures with finite lateral dimensions for ultra-efficient and optical crosstalk-free OLED displays.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The stratified structure of organic light-emitting diodes (OLEDs) confines much of the generated light within substrates or organic layers, limiting outcoupling to air. Macroscale half-ball lenses extract most substrate-trapped light but compromise the inherent planarity of OLEDs, while microlens arrays (MLAs), only tens of micrometres tall, preserve planarity yet provide only modest enhancements, particularly with limited lateral dimensions. Here, we introduce a systematic strategy to enhance outcoupling while maintaining near-planarity. By jointly tailoring the OLED device stack and the topography of near-planar outcoupling structures, we overcome the limited prompt extraction responsible for the modest performance of conventional MLAs. Our optimized devices reach an external quantum efficiency of 48.0% and a current efficiency of 192 cd A⁻¹, surpassing bare OLEDs (35.6%, 102 cd A⁻¹) and MLA-attached OLEDs (35.4%, 150 cd A⁻¹). This approach addresses trade-offs among intrusiveness, aperture ratio, and performance, providing a promising route to ultra-efficient, optical-crosstalk-free OLED displays.
