A variety of metal foil etched displays. These are super thin displays designed to be used in things like smart cards and credit cards, or laminated onto some other small, light weight device. Curious how the 8-segment displays feel a bit ancient, like old calculators.
What’s the possible range of interaction and communication that can happen solely with numbers, or even with no display whatsoever. Remember the early Motorola phone displays that only showed digits? Entirely operable, and more than sufficient, considering that telephones once had absolutely no display. Will new crazy, resource intensive features continue to get cobbled onto over-engineered, over-designed devices? Suppose things had to be subtracted from feature lists? What would go first?
