The white OLED displays measure 1.3 inches diagonally:
They’re plug-compatible with their 0.96 inch blue and yellow-blue siblings.
All of them are absurdly cute and surprisingly readable at close range, at least if you’re as nearsighted as I am.
Some preliminary fiddling suggests a Primary Red filter will make the white displays more dark-room friendly than the yellow-blue ones. Setting the “contrast” to 1 (rather than the default 255) doesn’t (seem to) make much difference, surely attributable to human vision’s logarithmic brightness sensitivity.
I must conjure some sort of case atop a bendy wire mount for E-Z visibility.
