Enhanced and directional electroluminescence from MicroLEDs using metallic or dielectric metasurfaces.
Article in Communications engineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Micro light-emitting diode devices (microLEDs) have the potential to lead the next generation of displays. However, their integration for achieving high brightness is severely limited by the challenge of their low external quantum efficiency (EQE). Another limiting factor of such devices is their Lambertian emission, which requires secondary optics to beam the emitted light in defined directions. To address these limitations, we introduce metallic and dielectric metasurfaces to improve light outcoupling efficiency and control the emission directionality of blue LEDs with micrometer size. The proposed mechanism relies on the interaction between light emitted by multiple quantum wells (MQWs) and metasurfaces supporting collective resonances that result from the coupling of localized resonances in nanoparticles throughout the array. We implemented a hexagonal diffraction lattice of resonant Al and SiO
