dave singleton Posted September 27, 2006 Share Posted September 27, 2006 Ok, for starters im slightly confused. By LED screen do you mean the kind that would be under the Video & Projection section of the forum, or are you talking about LED pannels, strips that would be under this section of the forum. Both use different methods or the same methods (sometimes). LED screens (Video) would have source material running through some form of media server etc, then that gets sent through the screens processing equipment. Could you make it slightly clearer which you mean? Link to comment Share on other sites More sharing options...
Simon258 Posted September 27, 2006 Author Share Posted September 27, 2006 ok, sorry for making a confusion here,what I meant is actually big LED screen board (10ft X 10 ft).I just bought few days ago, after installed, everything is perfectly connected, but I can't get the image on the board. so I just thinking, is it my supplier forgot to provide me the software?

gnomatron Posted September 27, 2006 Share Posted September 27, 2006 You seem terribly confused about this for someone who's just bought a very expensive piece of equipment. Try calling your supplier? they'd be a pretty poor supplier if they didn't give you some after-sales support on a piece of kit like that. Link to comment Share on other sites More sharing options...

CPlater1 Posted September 28, 2006 Share Posted September 28, 2006 What do you mean by LED screen? Will it be showing images like a signboard? Is it just a big colour changing block? Is there a manafacturers website? If you dont give this information we are unlikely to be able to help. Link to comment Share on other sites More sharing options...
niclights Posted September 28, 2006 Share Posted September 28, 2006 You are still being incredibly vague and your profile doesn't give much away. If you are talking about video screens these are hugely expensive (and heavy). The main manufacturers I know of are Barco and Lighthouse. Link to comment Share on other sites More sharing options...
LDODD Posted September 29, 2006 Share Posted September 29, 2006 I'd consider Lighthouse - assuming that you are looking for an LED video display... It's good to assume, when you don't have any more info to go on.... ?!? Link to comment Share on other sites More sharing options...
Simon258 Posted September 29, 2006 Author Share Posted September 29, 2006 what I meant is full colour LED video display.I need it to show some videos.I got a quotation from a china supplier, one meter sq is about USD 2000, for 40 mm pitch,is it reasonable?

djw1981 Posted September 29, 2006 Share Posted September 29, 2006 Niclights has already mentioned lighthouse and barco - have a look around their websites. Also try a seacrh on the BR for pitch and LED as I am fairly sure that a few weeks ago there was a topic discussing the size and distance from the screen of the viewers in relation to the pitch of the screen. ie for people at x distance you want a pitch of y mm.

Pete McCrea Posted September 29, 2006 Share Posted September 29, 2006 40mm will be good for people over approximately 40m away- the rule of thumb is about 1mm per metre for viewing distance. As others have mentioned, their is of course Barco, and Lighthouse. Then Toshiba make some good quality kit. Hibano had some nice quality kit on display at ISE in Brussels last Feb, though most manufacturers are topping out aroung the 25mm level now. There are more and more people entering the market place all the time. As your looking to install the kit, the options for cross hire isn't so much an issue, so it'll probably comedown to price and features. For outdoor use you'd be looking arounf the 5000cd/m2 (Candelas per Metre Squared, which IIRC is near as damn it a 'NIT' too). You then need to consider the way in which the individual modules are calibrated (Through use of a PC such as with the Barco kit, or self calibrating with the likes of the Tosh). Don't forget to price in the processor and possibly the support frames. I know with Barco that the 'Rental Structure' is a seperate item, but with Toshiba it's built in.

Toxopholist Posted September 29, 2006 Share Posted September 29, 2006 How to control a LED screen?Is it any standard software? To go back to your initial question, each type (though more often brand) will have its own propriatry processor which will have been supplied with the LED Panels for example for Barco a D230 or LEDpro is required... This behaves as the interface between your LED screen and video source, you need to make sure you consider your source material and check your processors capabilities... The processor often also handles the scaling of your images onto screen and switching between sources, although this is not always the case, see Toshiba, so you may also need to invest in a scaler/switcher, I'm a real fan of the Folsom Image pro HD,but then I tend to do a lot of Broadcast studio work on small pitch screens 6-12mm. As to software it again depends entirely on which system you are running.. As to Brand and type I would have to agree with Little DJ as to a basic spec... I like Barco, and Lighthouse for the outdoor gear, but then its what I tend to op from day to day... I would decide on a budget and if practical as suppliers for a demo, most will be happy to oblige considering the size of that kind of investment. If you can tell us the Brand and Model of your existing screen we can help you further with advice on your needs for control... Hope this helps Charlie Link to comment Share on other sites More sharing options...
