Multi-Primary Color Displays Emerge as Next-Gen Color Reproduction Technology Beyond RGB
Multi-Primary Color Display Emerges as Next-Gen Color Reproduction Technology

The display industry is shifting focus from resolution to color reproduction with multi-primary color technology. At the Shanghai conference, leaders like Hisense, BOE, and TCL CSOT showcased solutions expanding beyond BT.2020 standards. Hisense unveiled its RGBX architecture to boost color gamut and reduce blue light, while experts emphasized the need for unified ecosystem standards to commercialize this human-centric innovation.
The axis of display competition is shifting from resolution and brightness toward color reproduction and human visual perception.

Interesting. Though maybe not so surprising that "multi-primary color display technology ... was presented as a key direction for the next-generation display industry" at the “Multi Primary Color Display Ecosystem Conference”.

> reduce harmful blue light
enough studies and randomized control trials have been conducted, it is conclusively shown that blue light emitted from household devices does not interact meaningfully with sleep. metareview CRD420251034611 "non-significant reduction in sleep onset latency" means blue light has been conclusively observed to not delay sleep - it doesn't mean that blue light has not yet been observed to delay sleep, we instead know conclusively that it does not. even better, a registered trial one: https://clinicaltrials.gov/study/NCT01855126 - RCT where shining a bunch of blue light on old people's eyeballs didn't help them stay awake longer (going to bed too early is actually a more common clinical issue than staying up too late). well if it can't keep people awake, it doesn't keep them awake.
it's a great interview question though. "does blue light from screens cause sleep delay?" it doesn't. why do so many people think it does? why suffer with a piss colored screen?

This is really being driven by tandem OLED with blue phosphorescent (not fluorescent which is the current commercial design) layers, most likely from Universal Display Corp. The blue phosphorescent OLEDs have (note red/green are already) longer lifetime and and efficiency, but they aren't the deep blue you need for 3 primary displays.
Samsung and LG which both demoed ultra-wide color gamut/volume displays at SID 2026, but also CSOT/TCL. This allows even greater than BT.2020 coverage (APEX pixel is 131%!) or trade off for lifetime with higher brightness/efficiency.
The original 4 color LCDs (like RGBY/RGBW) was driven by a long ago need for brightness and resolution with fewer subpixels (see Samsung's Pentile RGBG arrangement). This both solves a different problem and the technology is being driven by a different development (and marketing).

Preventing selection is quite the useless and user antagonistic pattern...

Everything old is new again. Back in the 2010s Sharp tried to release a TV with an extra yellow colored subpixel. Commercially, it failed spectacularly.
