Talk:Flip-disc display

Fair use rationale for Image:Stockportbus.jpg
Image:Stockportbus.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

Not used in new installations
They are used on all the new buses round here!

 * Where are you from? Here in the USA, flip-dot displays on new buses are very rare.  Practically every transit authority in the USA have switched to LED displays.   ANDROS1337   03:59, 11 March 2009 (UTC)


 * In Germany, or at least in Rhineland-Platinate, in Frankfurt and in Berlin, it's the same, almost all transit companies use LEDs in their new buses.79.211.111.164 (talk) 19:57, 26 August 2009 (UTC)

Historical note
Back in the 1990s I was putting myself through uni as a car courier (ahh the days of 45 cents/litre!). I delivered a small package to the Ferranti plant near Pearson. The back of the parking lot was fenced off and filled with flip-disk displays that were constantly flipping, as test units one assumes. Ironically the next time I saw such a display up-close was at a local maker fair last winter, where they had one playing the classic "snake" game. He said he purchased it for $10 from a local electronics surplus store. I suspect that it came from the Ferranti plant after VA tech took over. Maury Markowitz (talk) 13:50, 6 November 2014 (UTC)

Note on mechanical faults
We have been using these displays for about two decades. It is true that they become unreliable with time - pixels get stuck. But there is a (temporary) cure. Just give it a strong punch - kick or punch the display. The pixels get unstuck and work again for some time. — Preceding unsigned comment added by 147.32.119.146 (talk) 14:15, 1 July 2018 (UTC)

Multi-color versions
I remember having seen displays that used cubes in stead of discs, rotating around a vertical axis, each of the four useable sides of the cube having different color (the one I recall had black, white, blue or green and red) and thus allowing display of multi-colored graphics. I could not find a matching article about that technology here. 80.79.86.129 (talk) 07:32, 6 March 2020 (UTC)
