Free-space communication with a pair of extremely high-density display panel and camera.
Article in iScience, 2026. 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
Visible light communication (VLC) has attracted attention in wireless communication. However, conventional VLC systems using limited LEDs are constrained in spatial data capacity. To overcome this limitation, optical camera communication (OCC) has been introduced, utilizing high-resolution display transmitters and imaging sensors as receivers to realize massively parallel, image-based data transmission. However, OCC performance is affected by optical aberrations and diffraction, which induce blur and inter-symbol interference, thus increasing the bit error rate (BER) under dense spatial encoding. To address this challenge, we propose a table-based coding (TBC) method that systematically eliminates pixel patterns prone to misclassification under optical blur. Through system modeling, impulse response analysis, and experimental validation, the proposed OCC system demonstrates projected throughput 33.975 Gb/s with a low BER, approaching the ideal blur-free limit of 217.438 Gb/s. These results demonstrate that TBC enables high-density, blur-tolerant optical communication, and highlights potential of display-based transmitters for next-generation free-space communication systems.
