I bought a Sharp LQ154M1LW12 off Ebay and it has Antiglare on it.

Did anyone find out if there is a difference between the Sharp LQ154M1LW12 and the Sharp LQ154M1LW02 ?

I got the LQ154M1LW12 in this group buy and it has anti-glare for sure.

so an AG removal would not be bad?

I thought the LQ154M1LW02 had the antiglare and the LQ154M1LW12 had the antireflection coating. I was initally trying to find a supplier who sold the LQ154M1LW12 because it had the glossy screen. I couldn't find any. I had to settle for a used LQ154M1LW02.

Well the Sharp LQ154M1LW12 I just bought off Ebay DOES have antiglare.

how easy is it to remove the AG layer?
(no I don't have access to the protected forum)

It's VERY difficult 15-20 hour soak and even then it's hard to pull off.

So, I've heard of a research projects which are using a second variably opaque panel to increase contrast ratios... the one I've heard of uses small LEDs to only illuminate the light segments to absolutely block out black pixels, ie no projected black. Such technology is still quite unavailable, however, I think a similar effect may be had by placing a second greyscale lcd in the lightpath... which should increase the contrast ratio by quite a bit. I think such a thing would require a hardware mod... ideally, stripping the colour information from the same feed, either at the dvi or panel interface level... so that the same signal drives the full colour panel and the greyscale panel. The contrast ratios should multipy, giving nearer black blacks and leaving non-blacks relatively untouched. Splitting the dvi cable, stripping the colour info and running into a second controller would allow for variable greyscale via contrast and brightness adjustments... so, minoten or anyone else, does this sound feasable? Anyone tried it? Not that I really have another grand to go on another panel, but it would be very nice to see the results.

Watching Sin City (black and white) on 19" professional lcd at 720p... it's very nice, but the black of the room is much darker than the black in the picture... would be nice to fix that. Perhaps this is deserving of its own topic.

The problem with placing another LCD in the projector is it wouldn’t transmit much light.

DJ

Yeah, for sure. But, with homebuilt there is as much light as you can give it. I've read of projectors with 20k lumens(!), so there's more than enough light to make it through the relatively transparant segments of the second panel.

minoten,
any new information on when you may plan another group buy ? (on controllers only this time ??)

thanks.

I just sent an email out to those that are on my mailing list (just send me an email at minoten-at-cox.net) today actually.
I am planning on running the group buy again within the next week sometime. Sooner than later I hope.

It will run for 2 weeks and the controllers will be $350 USD + S/H
Anyone outside of the US & Canada will need a Fedex or UPS Account #
It will work on all WUXGA 15.4" LCD Panels (tested on multiple monitors), but I was told it did not work on a 17" WUXGA LCD Panel.
This controller should support 480p via sync on green at the expense of losing 640x480@60hz via VGA, just like the 2nd group buy.
Lead time will be around ~5 weeks from the time the group buy begins (assuming everyone pays on time)

People will be able to place their order on my website and I will send them back a formal invoice with payment instructions/options. User then sends the payment to me, I will let you know when it arrives. I will then place my order with the manufacturer and wait an unknown amount of time for the order to be processed (2days for 1st group buy, 2 weeks for 2nd). Once items arrive here they will be promptly shipped out to you.

When you say ALL 15.4 WUXGA panels, do you mean all Sharp panels, or even the others like Hitachi, Toshiba, etc...?


heli0s

I mean all 15.4" WUXGA LCD Panels, not just Sharp.
I know someone has tested it with Toshiba, and it worked flawlessly.

The Sharp 15.4" WUXGA LCD follows the SPWG standards for a 15.4" WUXGA LCD Panel, that means that any other 15.4" WUXGA LCD Panels should work, if they follow SPWG standards (they all should).

I will try to find some retailers who can sell these LCD Panels to you guys, but for now I am concentrating on getting the group buy started (hopefully tonight).

Awww! I wish I had known that about 3 weeks ago. I ran accross a super cheap deal for a different brand wuxga panel, but I couldn't find a controller for it, so I passed it up and bought a 17" wide lcd panel tv instead.


heli0s

minoten,

I think you should stock some controllers in case someone wants to order one, they should get it right away without waiting 4 or 5 weeks.

If you want to loan me a couple thousand dollars I would be more than happy to do that.
It is called a group buy, I do not run a shop!.
If it was a store I would be selling these things for $450 a pop or something trying to pull in some nice profits!

Group Buy #3 has begun!

I am taking orders from right now up until March 17th (about 2 1/2 weeks)

WOOHOO!! The last piece to the puzzle!

Darn, I'll have to miss this one. Might there be another following this one (around the beginning of may)?

Does anyone know of any WUXGA LCDs that don't have anti-glare?

I don't know if they will remove anti-glare for you but you can chat with them online

http://www.screentekinc.com/compaq-lcd-screen.shtml

Yeah I know it's expensive.

minoten, i saw in the controller doc that it does not support WUXGA @ 72 or 75hz. Is this true ?

If true, it means it is not possible to display progressive cinema content (24 fps) or pal progressive content (25 fps) properly with this controller without stutter or telecine.

Also does the controller / sharp panel combo support 1080i (1080 interlaced ?)

Thanks for your response (and for your efforts )

It supports 1080i and 1080p.

Thanks for your responses. But at what refresh rates are 1080i and 1080p supported ?

Could someone who has the Sharp test this :
- WUXGA @ 48 hz
- WUXGA @ 50 hz
- WUXGA @ 72 hz
- WUXGA @ 75 hz

It would help me a lot to make my decision to purchase it or not

http://www.screentekinc.com/pixelbright-lcds.shtml these pannels are 50bux more minus the anti glare//with pixel bright coating .Pixel Bright coating will have no diffusion of light out of the lcd i can't wait to see thru one , looking awesome for our app. It is a high gloss clear coating. Sharper contrast
Crisper images
Colors that are richer
Wider viewing angles
No reflected hazy image pssh enough said . let me know what you think ...!!!

Can anyone post the timings of the panel when at 1920x1200@60hz with dvi input on nvidia? I've a 6600GT that I'm trying to use for WUXGA in X in linux. I've managed WUXGA with VGA, but not dvi. Might want to use powerstrip. Thanks!

See my post here: http://www.lumenlab.com/forums/index.php?s...ndpost&p=104114
I don't know about Linux, but with Windows XP, I could not get any of the Nvidia Series 80 drivers to work with these advanced timings. I had to use the 78.01 drivers.

can anyone tell me if they are succesfully running their windows desktop @ 1920x1080 using powerstrip via the VGA or DVI connector ?

... i'm contemplating changing my screen to handle the 16:10 ratio of a wuxga panel (112x70) vs. the 112x63 that I have now....

any info would be appreciated.

thanks,
gs

I have successfuly run 1920x1080 via VGA and DVI for my desktop, no problems there, ATI 9800 PRO. I didnt even have to use powerstrip.

Thanks for that Minoten. I'll have to see what my existing video card supports (no plans on upgrading in the near future)... I asked specifically about powerstrip as it provides custom resolutions not found in ATI drivers. What Cataylst version are you running with your 9800 Pro ? Thanks again.

gs

I am running whatever the latest version is, but I also had it running on the drivers back in May 2005 when I first received my kit

I also wanted to remind everyone that the GROUP BUY ENDS MARCH 17th!
Place your orders now! Late orders will not be processed!

I seem to have stumbled across Sharp's model number secret decoder ring:

Click to view attachment

It sheds some light (no pun intended) on the panels up on eBay, but some of the newer codes are missing. Obviously, the "display format" code M represents WUXGA. It looks like the anti-glare coating on the panels Minoten sourced is called "ASV" whatever that stands for. The LVDS interface is definitely correct.

I've also stumbled across a Sharp WUXGA panel that I haven't heard of before, the LQ154M1LM12. The guy at ScreenTek confirmed that the "coating treatment" code M is a high gloss anti-reflective coat.

Has anyone seen one of these panels? Anyone know its specs?

Does anyone know what ASV stands for? How about WVA?




(Yeah, it's true. I do a lot of stumbling.)

ASV seems to be something we don't want.

"As with previous AQUOS models, the new GD4U and GD6U series use Sharp’s proprietary Advanced Super View (ASV) LCD panels with Black TFT low-reflection coating which dramatically reduces glare, so they can be placed anywhere – even near windows, doors or other light sources. The units also offer 170-degree viewing angles, enabling consumers to watch TV clearly from anywhere in the room, as well as extremely high contrast for blacker blacks and clear, vivid pictures, and high brightness with exceptional color clarity."


Haven't looked for the other abbreviation yet.

Edit: WVA = wide viewing angle

ADV is Advanced Super View? That's why marketing people get the big bucks. There's no way I ever could have come up with a three letter acronym (TLA) that is so completely lacking in useful information. If it's advanced and super, though, I'm all for it.

For those of you still on the fence about this group buy, please look at these images provided to me courtesy of rallafatz, who was involved in group buy #2:

Best shots I have ever seen! He needs to come rebuild my projector.

Fantastic! I can't wait until I get my PJ built. I can only hope mine turns out half as well.

I too have ordered a controller from Minoten, however I am less certain about acquiring the LCD panel. While the panels appear to be plentiful, it would be a shame for us to be competing against each other on e-bay when the controllers are delivered.

Would it make sense to approach a supplier like ScreenTek with our own "group buy" and secure WUXGA panels at a reasonable cost and perhaps say, a "no dead pixel" guarantee?

Minoten, I know you were "snake bit" by your previous supplier; thus the decision to sell the only the controller. What's your opinion on the group forming a consortium and contacting a panel supplier like ScreenTek? What are the pitfalls? IMO, we could have some definite leverage on price and quality.

ScreenTekInc seems to be the only company that does the glare removal that everyone seems to want (I think?).

I remember contacting ScreenTekInc in the past for the first group buy, and they would not give me wholesale discounts unless I was an actual company. However, I will try to contact them again.

If need be, I could contact my old supplier and see if he can work something out, but I would rather not give him any more business unless we need to.

I poke around a bit, but please dont wait for me, send other companies emails and such, I cant do this alone.

ScreenTek is a very interesting company. They appear to be unique in a few ways, such as having their own clean room for refurbishing, removing and applying coatings, etc. This is way beyond the role of a typical VAR and unheard of for a distributor. They appear to be the real deal.

They are very clear about their pricing terms on the site. If you are reselling the panels as part of some sort of business and you give them a copy of your business' tax ID certificate, they will extend wholesale pricing. Otherwise, you pay retail. They are so upfront about this as to show openly both prices. A lot of their competitors selling refurbished and used panels won't list any price, and they insist that you to specify a "target price" in your quote request. Unless one of us happens to be a systems integrator or VAR, it seems pretty unlikely that they would give us the panels at wholesale.

Another interesting tidbit about ScreenTek is that they maintain a disconcerting number of aliases. LCDscreen.com, lcds4less.com, notebookLCDscreen.com, notebookdisplay.com, notebook-screen.com and laptoplcdscreen.com are ALL ScreenTek. Google their phone numbers and you'll see. Their member listing on the BBB site comes up, too. Mobility Guru (a.k.a. Tom's Hardware Guide) did an interesting interview (read: ad) with the Marketing Director that is available here.

BTW: According to the interview, they "offer a no dead pixel or zero bright dot defect guarantee" on all of their panels!

Seems to me that all one of us would have have is a federal tax ID number to get Wholesale. Thats not too hard to have

From my WUXGA LCD Notes: (may be incorrect)



WUXGA 15.4" LCD Dell Part Number: U0674, 2U917
(Used in Dell Inspiron 8500/8600/9100/xps / Dell Latitude D800 / Dell Precision M60)

I also believe there is a Hitachi WUXGA 15.4" LCD, but it suffers from slow response time, from what I remember.

This list is about a year old, so there are bound to be new models and revisions.

Hope this helps someone, screentekinc has yet to reply to me, no surprise there.

Well, it looks like I'll also be in the mix with the third group buyers looking for a *new* Sharp panel to replace the one I just hosed during my AR removal...

I bought my previous panel (RIP) on ebay, which had the nice fat layer of AR on it.
So, I decided it was about time that AR layer came off and rag soaked the panel.
I made sure to tape down the sides to protect the screen/ffc's from any exceess water seeping into the vital electronics and left it to soak overnight.
The next morning, I started peeling off the AR layer and to my surprise it actually came off without much trouble.
I was psyched that it came off so easy and started to clean up my work area. Without thinking, I started pulling at the tape I used to protect the sides of the screen and i heard

"RIIIIIIIIIIIIIIIIIP"

One of the side ffc's came completely off...
I was in shock for the rest of the day

Lesson learned here, either don't be a bonehead like me when removing the AR or buy an LCD with AR already removed.

Ouch. That has to be the saddest story I've read here on LL.

That's why I've never understood why people say to tape the ffc's when you do AG removal. It seems like it would cause a LOT more trouble when removing the tape.

I guess I was right.

Sorry about that verb0ten. My first Wuxga panel I did the same thing, and it was the easy AG also. My next 2 Wuxga's had the next to impossible AG. :angry:

I just spoke to Robert at ScreenTek and was told they do not have the Sharp LQ154M1LW01 or -02 panels in stock, have not had them for some time and do not anticipate having them.

Anyone come up with other sources?

Jon - which model LCD panel are you using and where did you buy it?

I have the Sharp LQ154M1LW12 in my Pj right now.

Got it here:

Ebay Link


I have the Sharp LQ154M1LW01 as a backup. I was using it but it had a slight smudge on the screen which was visible during bright scenes , so I got the new one.

I have contacted my old LCD supplier, I am going to see if he is willing to offer a group discount and still sell the panels on a per-individual basis.

We will see what he says.

I called ScreenTek with the same intention. I got the same responce. They gave me the number of Laptop Parts Warehouse. I called them, they had two in stock of LQ154M1LW02 so I ordered both, they didn't have any with the nice shiny screens. Unfortunatly both appear to be used. I'll have to wait until I get the driver board to see if there are any problems with the LCDs. I might send the pannels to ScreenTek to get them repolarized.
