Attention Lifter
Thank you for bringing me to my 1st visit to video...
A quick scan of the posts in the last 6 pages of this thread shows that you have some useful information to bring to the party. But it also shows that some of what you are saying is based on out of date information (3 years in this business is an eternity -- if it was a 3 year old Windows PC it would be a doorstop).
And your posts definitely can take on a very negative tone which is not in the spirit of diy. We are here to push the envelope. I have every confidence that it is possible to hack something together, and i know for sure that tomorrow there will be a new bit that will make it easier. And the day after that you will be able to buy it off the shelf.
So i ask you please contribute in a positive manner, never say never.
If i continue to get reports that you are not helping push forward, that you are disrupting the creative flow, i will have no option but to SinBin you. Consider this a formal warning.
That doesn't mean you can't point out potential dead-ends or problems, just do it positively.

I just saw the plumbing on your page. Kudos! It looks a lot like the stand I built to keep my PC off the floor.(helps keep the dog hair out..I have 2 bullmastiffs) Gives me some ideas for when I get my home theatre going.....off to the hardware store I go....I think my wife will understand.......yeah right! LOL

Re: Attention Lifter
I apologize for contributing to a problem in this forum. I write a lot in sports forums so I'm used to a less-sensitve/less-friendly atmosphere (w/o people taking anything personally). Some of my posts had a negative tone to them which may have deterred people from participating in here. For that, I apologize to the moderators and those who weren't involved but had to read this stuff. I felt like I was being completely ignored at first because my posts were quite long and that certain people didn't bother to read them. All I was doing was pointing out potential dead-ends and problems, and people saw that as being negative. While my tone may sometimes be negative, my feelings towards DIY projectors is not. I have always believed that there are solutions to everything. I just pointed out what I believed to be mistakes too harshly. Two people on here who overreacted (one simply because I suggeted he not buy something) now have a serious vendetta against me and I was unable to comment on anything (negative or positive) without being ignored or attacked. The other person is a very frequent poster in this thread, so I chose to stop posting in in this one for a while until he claimed he had kicked me out of it- which I didn't appreciate one bit. Again, I apologize to the moderators and from now on I will just suck it up and stop feeling like I have to defend myself against these particular individuals. I will also refrain from pointing out mistakes, etc. because it's not worth it to me and will only lead to more problems for everyone else.

I want to clear something up.
Lifter said I was feeding people false information. I have never knowingly ever feed people false information and I will not have anyone say I do.
Here are his exact words.
Well I hate to interupt with something "negative" (I know how sensitive you are), but you shouldn't be feeding people false information. I just read the article and it says Dell selected LVDS as the standard for their LAPTOP panels
Lifter says the article refers to Dell selecting LVDS for its LAPTOP panels.
*****************************************
He is wrong. The article refers to MONITOR panels. The words LAPTOP panels are not used in the article at all,.as you can see for yourself.
Here is the relevant part of the article
Cheng Chun-ping, Taipei; Shih-wei Kao, DigiTimes.com [Monday 9 December 2002]
Dell Computer reportedly has selected low voltage differential signaling (LVDS) as its standard interface for 15-inch LCD monitor panels and sent documents specifying the related requirements to its monitor producers, according to Taiwanese IC design companies.
The Standard Panel Work Group (SPWG), which consists of Dell, Hewlett-Packard (HP), IBM and Toshiba, reportedly will also choose LVDS as its standard interface for 15-inch LCD monitor panels early next year.
In my book a monitor panel is something you put on your desk. A laptop panel is something that goes on a laptop. Two completely different items.
You see Lifter, we have had to waste 2 pages of posts, get a moderator here to sort things out simply because you cannot read a simple article properly.
If you are a man you can apologise to me for saying I feed people false information. If you are a boy, well in that case I dont care

I'm totally just trying to be nice about this. I never meant you were feeding false information on purpose. Yes, they used the word monitor, but they meant laptop monitor, not desktop. That's all I was trying to say. A westerner would probably not word it like that, but it was written in Asia and maybe laptop screens are commonly called montiors there. And they call them monitor panels, not monitors. Look at the context it's used. They're talking about 15", which is the newest, largest, and most common for laptop panels. Desktop LCD's come in much larger sizes. But here's the main reason why it's laptop.
"As a result, the LVDS interface probably will soon become the mainstream interface for 15-inch LCD monitor panels, replacing the older transistor-transistor logic (TTI) interface"
It says they're replacing TTL. TTL is not used in desktop monitors (at least not to connect the panel to the PC). They're talking about internal systems. That means laptops, and possibly the internals of a desktop panel (although they wouldn't do that since it would be pointless to use LVDS for the internal transmission and DVI for the external). It doesn't say anything about replacing DVI.

Thank you for your reply. I am not trying to pin you into a corner for the sake of it.
Its just that you used the word LAPTOP panels whereas those words do not appear anywhere in the article at all. You applied your own interpretation onto the article and assume they are speaking about LAPTOP Panels. Further on down the article they do use the word NOTEBOOKS which has a definite meaning so I believe if they wanted to say these panels as used in LAPTOPS they would have done so.
Reading further down the article we see this
To minimize the effect of EMI (electro-magnetic interference), the LVDS interface has been widely adopted for notebooks and 17-inch and larger LCD monitors.
Here they do use the words LCD monitors explicitly.
One could reasonably come to the conclusion that if LVDS has been...... widely adopted for 17 inch and larger LCD MONITORS......., as they say, all they are doing is extending this technology to the 15 inch units.
17 inch and larger LCD screens are becoming affordable so it looks like there will be some monitors with DVI connections and some monitors with LVDS connections.
Thats not a standard is it. Thats two different technologies.
Hence my comments regarding the "DVI standard may not be so standard".
Not everyone likes the DVI standard according to what I have read. It is a pig of a connector. Hard to make, expensive and the Asians who make most of the LCD units don't like it.. The originators have tried to make it an all in one connector that serves both digital and analogue. Why they did not simply use a Digital outlet plus a standard analogue output beats me. Then customers could just plug into the appropriate hole whereas now you have to get the right cable. Always a source of error and frustration. Also if you own an analogue monitor and wish to plug into a DVI capable video card with a DVI connector you will have to throw away your standard analogue cable and go and buy one of these multipurpose DVI cables.
In my Proview 15 inch CRT monitor the analogue cable has a standard analogue plug on one end that goes into the computer, but the other end that goes into the monitor is not a connector at all. It is fixed. So what do people do if they want to upgrade to a late model video card which only has a DVI outlet.. Have to buy some sort of analogue to DVI adaptor. I bet that wont be cheap. Or throw away the monitor and get another one. Stupid idea.
My take is LVDS is the stronger technology , has a well established base, and will be widely used in laptops, and in desktop monitors.

You could be right, but I still think I interpreted correctly. I don't think the article is clear enough to assume either of us are 100% right, but I think they would have mentioned something about LVDS replacing DVI if your interpreted correctly. I did a search on the topic and I couldn't find anything in English on it. There does seem to be a few internal LVDS standards (like the 20-pin one) but personally, I'm not familiar with any external LVDS standard. External LVDS kits exist, but they are all different from one another. Take the one I bought years ago for example:
http://www.tridentdisplays.co.uk/solutions/lcd_kits/kits.shtml
[see the pic on the bottom right of the page- notice the extra connectors on the ends of the cable. Those are an LVDS transmitter and reciever- converting to and from 44-pin TTL connectors]
As you know, there are other LVDS external "kits" that have different connectors and different pinous. So if there is now one single LVDS standard for external applications, where can we find info on it?
I also still think that the industry in the West (perhaps not in Asia) doesn't like the idea of people easily hooking up laptop panels to PCs. Plasma TV's even have DVI inputs on them, and I find it unlikley that they'd wanna change it.
But my original point was, despite who interpreted the article correctly, DVI is still by all means a standard. And only one standard. DVI-D is just digital, but DVD-I also allows analog signals to be used as well. Still one standard. But they are more or less the same and one works w/ the other. Not the case for the many different types of LVDS (internal or external) and TTL systems.
The only 100% fact I can get out of that article is that they're going to phase out TTL. That's a good thing because there are probably more than 50 different types of TTL connectors and pinouts for various LCD panels (older ones).
Reading the article again, it does appear that they are all going to use one standard (I know I said earlier it wasn't likely), but I can't tell for sure because it just says "LVDS standard", whatever that means. It doesn't say that it means all pinouts and connecters will have to be the same- just the ICs. If it does mean that the connectors are all interchangable, that's very good news. It means that all LCD controller cards and SBCs w/ LCD controllers built in will all work with all newer panels without custom cables and adapters. But I still think common graphics cards like ATIs and Matroxes will still support DVI and will not have any LVDS connectors on them.
I think the question now is, if I'm right, and the panels will all use the same connectors, which LVDS internal system is going to be used for this new standard? If remp is right, then what will the external LVDS system look like?

come on you guys, i am having time off and i really would like test the 2 lcd's : NEC NLl6448AC33-18 and the Sharp LQ10D32A
so what do we do know... a/d converterboard and the right cables??
i have all technical info on both of them here in front of me (device specification and manual!)

Your LQ10D32A is an older laptop unit.
Pull price around $50.
5v supply
31 pin hirose connector
10.4 inch
262144 colours (18 bit)
640 x 480 resolution
TTL drive.
Sorry Uvodee its an older model not really worth spending the money for a controller. Our present knowledge of controllers is around the $200 mark. I am not pushing TTL. There are just too many variables. If it was a 20 pin LVDS could suggest a matching video card, or a stand alone controller around the $150 mark.
To maximise your dollar for projection purposes you need to score a better resolution panel say 1024 x 768 at about the $100 - $150 mark. Then the cost of the controller is more reasonable considering the substantialy better quality screen.
With present prices for LCD monitors so cheap (see above post) you would be better off buying a monitor and doing the mod to separate the vetical and horizontal boards. Gets you a modern product, direct analogue connection to your computer (or controller) and has contrast ratio 300 :1 Better product at a good price. Thats what happens when prices come down.
If you still want to go Digital you need to find a TTL controller for your panel. I cannot help you there. Someone else could.
Your other panel I have not looked at yet.

I've got a multi panel controller here now, with a couple of cables. I'm waiting for my first panel to arrive, it was a second choice panel but I'm OK with that for the moment. The one on the way is a TTL panel LQ121S1DG11. The seller claims it's a high contrast full motion video capable screen, what the hell the price was liveable.
The screen I'm looking for is an NEC NL10276AC30-04, if you wouldnt mind could you email me the specs on your NEC? I want to see if there are significant differances on the panel pinouts, if they are the same I suggest it may be a matter of adjusting the timings or such on the controller I have. I really havent even looked at it since it got here.... just sort of sits there teasing me.... ( got the no panel yet blues )

Your panel will run on my controller...but it's prety much on par with my LQ121S1DG11. The thing that I do notice however is that your 10.4 NEC panel takes the exact same cable as the 10.4 inch Sharp LQ10D42. So is it safe to say that all 10.4 inch TTL panels with certain given parameters (timing's etc..) are all the same? Dont get me wrong...I'm not looking for universallity here....just commonallities. If this is the case... and it also applies to the LVDS method of connection then there is a lot of possibillities out there....sort of goes back to my original question..."are there just soo many panels out there, that the controller manufacturers only test a few and dont bother to tell us...oh yes...it should also support....but we havent tried those yet" I see in the documentation you found "compatible with....-18 -24 -27 model number suffixes. This is positive info for me 🙂 Now I'm eager to find more pinouts for LVDS panels.
any comment remp? (looking good isnt it?)

Please to explain.
Uvodee's panels (both of them are very similar) are TTL driven.
Your controller is LVDS output.
You cannot drive a TTL panel with LVDS. Does your controller have TTL output. I did not realise that. Makes it rather a versatile controller. Why don't you get Uvodee to ship his panels to you and try them out. Then if its successful that opens one more door for us guys.
You put your finger on a good point about the similarity between panels and timing. Basically all TFT panels of the same size have the same timing. But there is another factor.
Assume you have to cover 100 metres in 10 minutes. At each meter along the way you have to plant a tree.
Now some guys (and gals) could go really slowly and just make it on time.
Other more athletic types could race along, stop every meter plant the tree and get to the finish in lets say 5 minutes.
So both do the same job, but the faster guys do it quicker. Your eyes see the trees being planted quicker. Now if someone could do it in 1 second, you could say hey thats fast I didnt even see it happen and now all those trees are there. And he does it again with different trees so you are now starting to see a fast "picture".
This has to do with full motion video.
Some panels even though they present the same information are just too slow to be useful for full motion video. They are OK for presenting slow changing information such as computer data where the picture only changes slowly.
You can have then two panels. Both will show a VGA screen but one is slow and is a data panel. The other is fast and can be used for full motion video.
There is no way to make a slow panel go quicker. Doesnt matter how quickly you feed it the information. The slow panel will not set it's ready signal until it is ready for more information.
The measurement is the responce time. If its slow forget the panel. If its fast could be OK for full motion video.
If you have a look at my post above in reply to Rekr, you can see I have posted the monitor responce time. Thats a good responce time.
My 10.4 inch projection panel at home is not bad but as soon as a fast action sport event comes on I see large parts of the picture struggling to keep up with the action. 90 percent of the time its not noticable. 10 percent of the time it is. But then again, its a 10 year old panel.
So you are right most panels of a particular size take similar timing but only the faster panels are suitable for full motion video.

Your panel will run on my controller..

Yes my controller has 2 TTL ports and 1 LVDS port, also a VGA port. I have cables for 2 different TTL panels and 1 LVDS cable for the NEC panel they list as "tested". My panel should be here this coming week, as I said it was my second choice panel I'd rather have found an LVDS panel. The seller did state that it was suitable for "full multi media" so I hope his deffinition of "full multi media" isnt too different from ours. This is first generation I suppose, once I prove this will work I'll get the go ahead to find what will undoubtably be a more expensive panel. Or maybe it will work just dandy and I can proceed with my other plans without having to tinker with this too much more 😉

I read the response time on my panel's spec sheet as follows
rise 15 ms
decay 30 ms
In a couple of days it wont be theory anyhow 😉
