The "departure board" display refers (I don't know the name) to mechanical display, where all the possible things (digits, letters, labels etc.) it can display are written on plates, which are all hanging on an axis. When the axis rotates, the plates fall over, until the desired plate is shown. It is often used in railroad stations for departure/arrival boards and some old public clocks.

- Yeah, what's the technical name for this? It's de:Fallblattanzeige in German, but I'd really like to know the english term. Peter S. 20:21, 19 July 2005 (UTC)
- I've been looking on eBay for clock-radios and noticed that a clock-radio with such kind of clock display is widely called 'flip clock radio'. By the way, I'm a proud owner of such a clock-radio! 220.127.116.11 17:31, 29 April 2006 (UTC)
- I believe the technical term is "split-flap display" Garfield226 13:58, 26 June 2006 (UTC)
- Hi, everyone! I spent far too much time on Google not finding the answers, when I finally discovered this talk page! I've since added a page called Split-flap display (and some redirects here and there). Please let me know what you think! Tyler Mitchell 07:39, 26 October 2006 (UTC)
- Sure, why do you ask? And I know of leet. Samohyl Jan 06:12, 4 October 2005 (UTC)
- With this picture, some readers might think that all VFDs are dot matrix, while most of them are still 7-segment.
Shouldn't the word "plasma" be included somewhere in the listing? Just a thought. Nicholasink 02:52, 13 March 2006 (UTC)
Digital vs Analog
I dispute the division into digital and analog displays. How do you differentiate them? By input? Early CRT computer monitors had digital input (see MDA, CGA, and EGA for example). Many LCDs have analog inputs, furthermore, the crystals are driven by an analog voltage, so an LCD monitor can be entirely analog. A laser display doesn't need anything digital either. A better division would be something like fixed-pixel displays vs the rest. Totsugeki 07:39, 10 June 2007 (UTC)
- I believe I did that 2 years ago or so, to distinguish between displays from digital and analog era. This article needs to be reorganized, to be more clear about what technology is obsolete (and from what time period), what is widely used today and what is experimental. Feel free to do that. Samohyl Jan 19:06, 10 June 2007 (UTC)
Yes, the classificatio into digital vs. analog is not quite distinct as stated above. A truely analog display would e.g. be a bargraph indicating a voltage, etc.
The article "electronic display" as opposed to displays with fixed (e.g. printed) information content, visual output vs. tactile output, "direct view displays' vs. "projection displays", displays with a fixed pixel raster (e.g. LCDs) vs. those with a flexible raster (e.g. CRT), reflective mode of observation vs. transmissive mode, etc. should be re-organized and re-structured.
This could e.g. be done along a timeline where the CRT TV appears amazingly early (even before the Nixie tube).
In addition to 7-segment, 14-segment, and 16-segment displays, there were 8-segment displays, which were used on devices like
- Thanks. I don't think these warrant a separate article, but a section to 7-segment display would be nice (there is a remark about them in fact). Samohyl Jan (talk) 08:49, 5 January 2008 (UTC)
The section Display device#Early devices is unnecessarily inclusive, as it lists "modern" displays such as plasma and LED, and newer gen displays like OLED and SED. Not sure if the section title "Early devices" is applicable, since e.g. LEDs have been around for years, but are still useful and contemporary. Yngvarr (t) (c) 15:40, 23 December 2008 (UTC)
Ok... So I was searching if there has ever been any attempt to invent computer and television screens that didn't relied on light to output their immediate contents (One could say that printers output "ROM data" and photic screens output "both ROM and RAM data") but I'm lost by al the jargon in here... Am I alone to think this must be made friendlier to the less technical-jargon savvy? 'Cause I bet the "Etch A Sketch" or "Magna Doodle" toy counts as an aphotic screen and as such deserves a place here, even if it is way too mechanical when compaired with the other items... Which are more electromechanical...Undead Herle King (talk) 04:23, 17 July 2009 (UTC)
Analog 'Digital' Displays need mentioning
I've been looking lately for info on displays from the 1930s or so (I don't know what they're called), which displayed information by scrolling through fields of electric lights- much like modern information screens. They don't seem to be mentioned at all here.theBOBbobato (talk) 21:23, 7 November 2009 (UTC)
Printers are not display devices or could at least be left out of this article. Film recorders are *not* display devices, though I suppose you could argue that's how the Dr. Strangelove-style NORAD screens did their thing. --Wtshymanski (talk) 14:50, 10 February 2010 (UTC)
I sorted the contents of this article into more specific sections rather than what previously appeared to be a "List of every single display device type and every single technology related to display devices". There are some entries, however, that I'd need help sorting into proper section, perhaps necessitating further subsections:
- IBM 2250
- Tektronix 4014
- Cathode ray tube (CRT)
- Bistable display
- Electronic paper
- Nixie tube displays
- Vector display
- Flat panel display
- Vacuum fluorescent display (VF)
- Cold Cathode Fluorescent Lamp (CCFL). The lamps used in CCFL backlighting for LCD displays. CCFL backlighting is a type of fluorescent backlighting or edge lighting. One or more fluorescent lamps are behind the LCD panel, providing light that is either blocked (appearing as a black screen) or passed (appearing as a white screen when no video is present) by the LCD cell.
An anti-glare, anti-reflective display for mobile devices
Scientists (Valerio Pruneri and team) are reporting in the journal ACS Applied Materials & Interfaces that they’ve developed a novel glass surface that reduces both glare and reflection, which continue to plague even the best mobile displays today. 2014-07-16
