Technology

A beam sweeps a phosphor coating, which emits while struck and then persists. The color belongs to the phosphor, not the beam; the P-number names the compound.

P1's willemite with arsenic added, which lengthens the decay by orders of magnitude and leaves the color alone — this palette and P1 are the same green, and differ only in how long it lasts. At hundreds of milliseconds the screen is still near full brightness when the next refresh arrives, so there is no flicker to see at any refresh rate. It is paid for in smear.

A preset sets the display and its simulation. Everything stays adjustable — and Reset puts all of it back, switches, styles and engine alike.
