The pursuit of a more immersive image takes the industry beyond mere brightness. The goal now is to achieve intense and precise colors, defined by standards like DCI-P3 and the broader Rec. 2020. To achieve them, emitters are needed that generate light with high spectral purity, a challenge where current organic materials show limitations. This has focused research on alternatives like perovskite.
Cold Injection: A Step Toward Viable Perovskite Manufacturing 🏭
Color purity is measured with the FWHM (full width at half maximum); a low value indicates a pure color, like an isolated musical note. Perovskite emitters offer a very narrow FWHM, key to covering the Rec. 2020 gamut. The challenge was their manufacturing at scale. The cold injection technique solves this by depositing the perovskite layer in a controlled manner compatible with industrial processes, preserving its optical properties and facilitating its integration into displays.
Our Eyes Apologize for Having So Many Cones 👁️
After years of settling for seeing the world in slightly out-of-tune color chords, now technology insists that we distinguish every individual note. Soon, watching a scene will be like listening to a professional tuner criticize every pixel. One almost misses the era when magenta was just a weird pink. Our poor eyes, accustomed to approximation, will have to step up (or the cones) to appreciate so much imposed chromatic perfection.
