I just got a box of old compaq laptops from a friend who was cleaning house, I got about 12 working SHARP LQ9DO10 8.4 " LCD screens, I'm hoping you guys figure this junk out so maybe i can hook one of these babys up. They were free, so if there is nothing I can do with them I haven't lost out 🙂

Sorry could not find much about your LQ9D010 panels
Its a Sharp 9.1 inch panel. Got 15 pin data connector and is/was a notebook panel. Check out

www.eio.com

LCD forum. One guy there has some and looking for info on your panel. He may have found some. An email to him might help.


Along the way I found some useful info about controllers. Might be useful for Shadowfax.

Controller cards for any resolution from QVGA to WUXGA.
Composite Video in, S-Video in. NTSC/PAL. Analogue computer in. DVI in. Drives the panel of your choice.

Another controller complete with refurbished 12.1 inch 16 million colour TFT LCD. Looks like it takes in analogue computer output. $350 USD.

Remp you might be on to something, if you buy that $350 dolar kit, then one of those $99 dollar viewsonic LCd recievers I saw in a previous post, you would pretty much have all the connections needed to watch video form any source (TV,DVD,VCR,) as well as be able to hoook up directly to a computer. $450 plus the cost of a projector, isn't bad considering the leap in quality you would be getting, still way better then a $5,000 dollar lcd projector.

P.S. Thanks for the info on the Sharps, apparently they are only 256 color lcds, which I don't think would be to good for this application.

so good to see ....

It's good to see forward progress and creative sollutions to a puzzle that has had it's day! I firmly believe that amongst us we have found the combinations needed to build some wonderfull PJ's.

I'll save the money of a comercial PJ and it's mega expensive bulbs....and put it towards my ultralight 😉

Got my card...now to wait for my panel...I hate waiting.

Tested my reflector last night (big shiny bowl) my prelim tests look like I should go ahead and punch a hole in the bottom and try the lamp with the arc tube 90 degree's to the bowl's opening.

I've been advised by a trusted friend that I shouldnt need a reflector with the HID, and I think he is right. But at the cost of a $20.00 stainless steel bowl I just cant resist. The lamp is "wicked bright" all on it's own, but with the reflector it does seem to "focus" the light much better. (besides the wife allready has a bowl for mixing her bread dough...she cant use 2 at once ~s~ )

Just a note to the folks here....I noticed a nice fan on the Dell 15 inch thread. It's a long "squirel type" fan used in photocopy machines. I've seen these in the local "Princess Auto" I'll be getting one to cool the air gap between my insulating glass.

Untill I saw ywh's post I couldnt see a use for this sort of fan, sure glad he posted his rig for us to look at. Then a real nice Aluminum fan made in Germany which will be thermostatically controlled for speed vs heat to cool the lamp housing itself. Now all I have to do is figure out how to keep bugs out of my PJ ..I hear moth's and such like bright light 😎

PS anybody got a 20 inch ID alluminum tube they dont need? The "Theatre Tube" or "Projection Pillar" is soon to be born!....at least I hope so 😉

LVDS

Hi there,

Interresting info from Digitimes.com that validates some of the thinking in this thread.

__________________________
Dell selects LVDS as standard interface for 15-inch LCD monitor panels
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.

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.

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.

Topshine Electronics, the leading Taiwanese LVDS IC supplier, predicts its monthly shipments will increase from 1.2 million chips currently to between 1.5 million to two million chips next year.

After reading your very interesting post I went to
www.digitimes.com

Thats an interesting site.
I entered LVDS in the search box and found the articles you mentioned.

Most interesting. So the much touted DVI standard may not be so standard after all. I am not surprised. Asians know how to hook up panels and get them to communicate at high speed. They have been doing it for years with success in the LVDS standard. You would think panel manufacturers could work out ONE standard and stick to it.

I also noticed Panstera is offering a 6 way LCD controller board. This looked pretty interesting to follow up but right at the moment panstera has been taken over and I could not dig out information on their 6 way controller.

There were 3 controllers listed but 2 mentioned radar insertion. Not for us. The third controller I could not get the link to work. That 6 way Panstera LCD controller needs follow up. It could be useful.

Thanks very much for the interesting information. Seems we are on the right track with LVDS.

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. It just means they're going to completely phase out TTL. It doesn't mean that the connectors and pinouts of all LVDS panels will match all LVDS controllers. I don't think laptop makers like the idea of someone hooking up any Gateway panel to any Dell laptop (and vice versa). DVI is and will remain the standard for desktop LCD montiors (including Dell's). I don't think much is going to change. We're not gonna see the GeForce 5 card with an LVDS connector on it. With the amount of old LCD panels floating around, it would kill the desktop LCD market if people could easily just do what we're looking to do. Look at those crappy Sharp 14" TV's that sell for $1000. And we all know how much LCD projectors cost. They're making a killing solely because there's no easy way to hook up laptop panels. While LCDs are status quo for laptops, they remain a luxury for any other application. That means money for them. The fact that it's dangerous may also have something to do with it (backlight inverters can supposedly kill you). But DVI is still the one and only digital standard for connecting desktop LCD monitors.

I for one did not get the impression that remp was trying to say "the connectors and pinouts of all LVDS panels will match all LVDS controllers".
I really dont see how you can predict the future of DVI (seeing as you didnt know that DVI comes in more than one flavour) or the future of Nvidia based video cards. The information I got from the preceeding posts was that Dell is going to use only LVDS panels "inside" their monitors... no mention there of connecting the panel to the computer with LVDS... personally I'd say they are using DVI to get to the monitor then using the LVDS standard to actually feed the panel.

remp and exipnos good research folks!

No I never said any LVDS will fit or connect to any other LVDS.

There are several flavours of LVDS
LVDS 1
LVDS 2
LVDS 3

Different connectors and so on.
The thing is we are getting a handle on this.

Lifter If you are going to quote me how about quoting me what I said , not what you think I said

This is what I said
So the much touted DVI standard may not be so standard after all. I am not surprised. Asians know how to hook up panels and get them to communicate at high speed. They have been doing it for years with success in the LVDS standard. You would think panel manufacturers could work out ONE standard and stick to it.

You quoted me as saying DVI is not a standard.

Big difference between what I said and what you said.

Anyway no one can say that XX is a standard. There have been heaps of standards before this and they have all been modified one way or another.

So let me get this straight Lifter. If you needed a good panel and Hello its a DELL and it had a LVDS connection you would not be open minded and look at it as a possibility because it does not have a DVI-D connector. Is that what you are saying.

Thats why I think you are a jerk. You keep trying to pick holes in things and what people say. All of us here are interested in going forward not backwards.
On page 10 I posted nearly a whole page of good solid progress that everyone has contributed, except you.
I take a great deal of pride in making progress and so do the other guys. Its interesting and by using our brains we have a chance of success. Every other thread or forum I have seen says you cannot do it but we can. With you or without you. Won't make any difference.

Lifter...thanks so much for clearing up my obvious error in assuming that I may at some point in time or another stumble across a reasonable sollution to this project. And by all means thank you for stopping me from plugging my keyboard into my S video port. WHEW! that was a close one

I would like to point out that DVI-D has indeed 24 pins (even if it wont work) http://www.ati.com/support/connectors/pinouts/pinoutsfordvi-d.html

You are correct though DVI-I has 29 pins http://www.ati.com/support/connectors/pinouts/pinoutsfordvi-i.html

Does this look familiar? You had some info to share with us, but chose not to. You told me I was wrong in my pin count...came off as this expert in "conectivity" and didnt even blink when I shoved the links to DVI pinouts under your nose and proved that there is a DVI with only 24 pins. You assume that we must all be morons by the way you post to us. If we were toe to toe and you were condecending to me as you were when you told me that a keyboard would plug into an Svideo port (like I was some sort of idiot) we would be doing more than talking ....

wake up lifter...it was all just a bad dream...or are you like this in person also?

I have had a word with the moderators about Lifter and the story is if he continues being a negative influence ( a pest see moderator statement) we can ask for him to be sin binned.

I vote for a sin bin for Lifter on the grounds that every time he posts the thread goes to hell and we have to waste time setting him straight.
