STC's 1986 Display Prototype Stalled at 200V, Limiting Adoption

Summary
A BBC Archive report resurfaced STC’s 1986 prototype display, showing a persistent screen technology that never reached broad use.
The main obstacle appears to have been its 200-volt activation requirement, far higher than practical for widespread commercial adoption.
Unlike e-ink, which flips black and white particles, STC’s design used a fluid whose molecules either aligned to pass light or scattered to block it.
The archive clip offers a rare look at an alternative display path from the early portable-computing era, highlighting a technology eclipsed by cheaper, more practical persistent screens.
