Advancing OLEDs: New Spectroscopy Boosts Lifespan
Credit: Scitech DailyHigh-resolution, full-color displays—like those in foldable smartphones and ultrathin TVs—depend on organic light-emitting diodes (OLEDs). OLEDs are gaining popularity due to their flexibility, self-illumination, light weight, slim design, high contrast, and low power consumption.An OLED consists of several ultrathin organic layers placed between two electrodes, each with a distinct function. When voltage...
