Editing Guidelines Please remember these guidelines when editing a film article: If a non-film article already exists with the name of the film that you are trying to create an article for, disambiguate and use (film) in the title: Film Title (film) For more information see: Wikipedia:Naming conventions (films) When writing an article about a particular film, the general format should be a concise lead section, followed by a plot summary of no more than 900 words, production details, a cast list, a reception section, and references. Create an Infobox that tells all pertinent information about the film.

Since when has film been "video-capable"? Girolamo Savonarola 09:24, 17 November 2006 (UTC)

Contents 1 LED Displays - Why not "video capable"? 2 Holography? 3 Free-space display? 4 VFD & nixie... and scope? 5 Incandescent matrix display

[edit] LED Displays - Why not "video capable"?

Why isn't LED display technology "video capable"? For small displays, maybe not, but large LED displays can for sure display video. LED video billboards are making widespread appearances. Andros 1337 02:51, 18 November 2006 (UTC)

LEDs are entirely video capable. I think the confusion lies in the fact that LED video displays scale down very poorly. Changing --Codeczero 22:55, 26 November 2006 (UTC)

[edit] Holography?

There is no such thing as a moving hologram. The data transfer rate required for an hypothetical moving holographic display is probably beyond current computer technology. The article describes reusable holograms and some digital applications, but this doesn't fit in with the rest of the list so I'm removing it. Potatoswatter 00:49, 12 February 2007 (UTC)

I don't agree with the removing of holography from this template. You can even display moving holograms quite easily, using the same technique as movie projectors. See for example http://www.holocinema.com --danh 23:26, 12 February 2007 (UTC)

In that case it belongs under static with the other projectors, since it's not a general-purpose display device... This is such a broad subject for a navigation template... Potatoswatter 00:13, 13 February 2007 (UTC)

Holography definitely belongs to 3D rather than static media. The movie projector technique is by no means the only one, interactive displays are no problem. Try searching for "holographic display", it already gives impressive results. --Danh 14:44, 13 February 2007 (UTC)

Nope. I just found product pages for other kinds of volumetric displays, and references to possible future technology. The first hit on Wikipedia was hogel. Potatoswatter 15:21, 13 February 2007 (UTC)

You're right, these are all volumetric displays. --Danh 00:52, 14 February 2007 (UTC)

[edit] Free-space display?

It only seems there are two types of free-space display: laser light shows and rear projection into mist. The first is non-imaging. The second is not distinct from DLP. Does either belong here? I'm leaving in because I'm partial to laser light shows. Potatoswatter 01:13, 12 February 2007 (UTC)

[edit] VFD & nixie... and scope?

Hmm... only VFD and nixie here are mere alphanumeric displays. So I'm removing them...

This is part of Wikiproject Movies... so it would seem that non-imaging technologies don't belong. There are so many technologies *not* listed, and the only really interesting or nearly complete part of this list seems to be flat television-type displays. Which are reduced to a list of acronyms which are confusing even though I know what they stand for. A look at category:display technology gives an idea of what's not covered.

In particular stereoscopy is an odd one out here.

Anyway... hope this "clean-up" helped :v) .

Potatoswatter 02:20, 12 February 2007 (UTC)

A film template, huh, I always thought it was more of an electronics template. If it were an electronics template I'd be tempted to break it down into electromechanical, high-voltage, and low voltage.--Dispenser 03:21, 14 February 2007 (UTC)

[edit] Incandescent matrix display

"Incandescent matrix display" links to "Incandescent light bulb", where the matrix display isn't explained at all. I would like an article about it. I've requested one in Electronics components. I'm changing the link to be a link to the non-existant article to reflect that. 85.211.141.70 18:45, 17 July 2007 (UTC)

What do you really want to know? Light bulbs are cheap and if you want to pay someone to replace burnt out ones, you can use a large number to display graphics. I'm almost curious whether there's a history of the first time someone built an array of digital drivers big enough to power a roadside sign... or whether it's ever been the most practical solution to any application. Potatoswatter 22:00, 18 July 2007 (UTC)

A description of what it is and how it works. 81.6.242.110 16:08, 19 July 2007 (UTC)

I assume it's a grid of light bulbs controlled by a computer, and I suspect the name was made up by the person who added it to the template. Potatoswatter 00:21, 20 July 2007 (UTC)
