The yellow-on-green matrix displays used for the scoreboard in events
like the Wimbledon tennis championships exhibit such good contrast
even in direct sunlight. Can someone please explain what display
technology is used ?

'Flip'-Type display, on plate of metal per Pixel, one side flat black,
the other bright yellow, flipped over by an electric manget.

IIRC...

Thanks Michael. I mentally "invented" such a system myself, but the
mechanical flipping somehow seemed a bit crude in this day and age,
and thought that it might be something more purely electronic.

It eats power while changing state, but not while "lit"
like most "purely electronic" devices. The application is
low resolution, low speed, and low refresh rate so it's got
several cost advantages over say a great big TV display or
even a light bulb matrix.

Staver used to make these mechanical displays, but that product line
was sold off, years ago. Do a Google search on Staver and Displays and
you'll find the current manufacturer. I built a custom controller for a
bank of these for Ch 55 in Orlando years ago, for their telethons.

This type of display is also used on buses where I live (Toronto)
