LCD panels

[Rekr]

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.

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

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.

Hi there,

In case you want LCD industry news similar to digitime.com check out these links.

http://www.panelx.com/index.php3 there are some lcd/contoller combos here with prices if you register. Expensive though.

Last one that I forgot about previously.

http://optics.org/ This is a very good site with buyers guide that lists companies in all related fields. Good for finding suppliers for our various components.

Cheers,

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.
