Passive color gemstone display
From apm
Up: Gem-gum display technology
There are many ways how this could be done.
Contents
Active F-center tuning
Dynamically tuning gemstone F-centers by applying and tuning forces or even switching out ligands.
For how this could work see: Organometallic gemstone-like compound
Structural color
Actuating comb like structures like the ones found on butterfly wings.
Switching color mechanically
Rotating wheels chains (or whatever) with different colors on different sides
structures need to be gig enough to have optical effect
Improving other existing passive display technologies by the far more advanced capabilities of gemstone metamaterial technology
Mechanical properties
Combining color display like properties with emulated elasticity should be possible.
Will be an interesting challenge.
Such flexible display technology will be way more durable, kink-, and and scratch-resistant compared to the polymer based flex displays of today (2021…2022).
