Been following this thread for days now, great stuff guys.

I was just down looking at my LCD to try and determine how much anti-glare it had and noticed that my UV filter was a little wrinkled at the top, which got me thinking...

What if we just attached the UV filter film to the anti-glare side of the LCD?

I'm guessing we'd need to use some spray on adhesive or somthing if it's actually the glue that's filling in the rough surface. If it works we'd still have UV filtering, we'd enhance brightness and we'd have a ready made supply of film.

Thoughts?

If I have some time this weekend I'll try just tacking the film on and see what I get.

Greg,,

please beware,, we need to find best solution of attaching any film,,

for every very tiny artifact will show like boulder on your screen,,

yes I had thought of the U/V sheet myself quite a while ago,, but attachment was and still is the issue

CARE PLEASE,, ONE AND ALL

Hey Mikyd: As far as screen door, yes, but it seem to have added great detail to the display in that aspect. Whites, and blacks look obviously better and I didn't notice hotspotting in the short test I did. Earlier Elken mentioned watching a movie with some actor wearing a colderoy (spell check) jacket and he (Elken) didn't realize that it was colderoy until viewing it with the tape test.

As far as heat, Mark has stated that less films adhesed to the panel reduces heat so 'butting' up the polarizers may be efficient in this regard. Although, it was also said that placing a 'clear' film on top of the 'antiglare' somehow but not adhesed also adds to cooling the panel but as I see it there must be some sort of adhesive to 'fill' the curves of the antiglare to get the clarity we all seek. Hope Mark can ellaborate on this.

Higher wattage bulb. Elken is still coming up with information regarding the polarizers, since this a new discovery enevitably we will also find out if there is any hotspotting issues or washing out of contrast of our LCD's then we will have to look into the amount of brightness our bulb should be. I fear this will turn out to be a calibration issue with what performance we want out of our personal pj's. I mentioned using some sort of dimming mechanism on the ballast but as Mark corrected me these ballast's run specifically on a frequency to maintain the bulb's arc. This is where you all come in to provide this new discovery some help to make it work proficiently.

As far as the sliding box. Mark did say that this would work better should you decide to place the front polarizer there. Some of us twist the triple for focusing so I guess it wouldn't be appropriate.

Hey Greg: I'd say do it, seems we are all pioneers when it comes to making this work out for the next generation LL projector enthusiast.

DAM, YOU GUYS ROCK!!!

Ok guys pics to follow shortly


do you how %$%#$^% hard it is to do surgery and then post as ya fly...


hold your breathe, because now you will see the first ever pic of no antiglare surface on a TFT display

MARK are you here,,, calling markus,,,, NOW

HEHEHEHE, get the wifey to help Elken, and GET MORE PORT!!, your gonna need it

you've got a polarizer to replace the lcd one already? cool .... I'm at the polarization.com site now trying to work it into the budget ;-)

she fired me,, can I borrow yours?

Are you kidding, I'm currently trying to keep her after neglecting her after starting this thread!!!

Ok bussiness first...


I have been requested to show methods and pitfalls of tape testing..


and cleaning.....












MARK I HAVE THE BIGGEST MOST GIAGANTIC SURPRISE FOR YOU<<< BUT YOU MUST HERE FOR ME TO REVEAL IT>>>>>>>

OH holy mother.. I dont believe it myself wowwwwwwwww

bussiness first

first pic is of benq after few days of tape stuck as you can see yuk!!!!!

second pic cleaning process,, used mineral turps,, (firts thing grabbed in too big a hurry for big test ) then used kitchen cleaner spray and wipe type,,,, then the best other polisher SPIT and polish heheheheheheh

third and fourth pic the other test panel used as a sticking cow,,,

as you can also see I used The DeathRay method,,, works very well also the method I used other day,, but bubblies were in it,, not worried about that

which you can see in fifth againt a light,, observe how image is not diffuse..


the sixth one is the one and only one that is the one that everyone wants to see which one it is we have all waited for,,, 42 oh whats the question???? ,,, ohhhhh shivers ran out of space,,,,,,, !!!!!!!!!!!!!!

ok here tis

this is what you get without the antiglare/polariser on PJ

oh PS,,, that darn blinding white background is the

FUL size 8' by 4' LIGHT FUSION screen... with MMUDse coating

Elken: Are you waiting for Mark, cause....the suspense is killing us!

Here is a pic,,,

not saying just yet how it was achieved,,,,

I want to walk very carfully here,,,




Clive.....

Interesting. It's much brighter, but the blacks look lighter as well as the whites. It looks to be a decrease in contrast.

Thats one of the questions I had about the amount of lumens our current bulb is pushing if we do this. Although, not seeing the full picture here yet, if it's possible that we may have to go down to 250watts instead or have a way to adjust dimming the bulb somehow. But we'll see what Elken has next to show us.

(edit) Which may explain why the commercials are so high in contrast i.e...thousands:1

bear in mind that this is a pure proof of concept under very difficult setup conditions,,, if I had full optics lab setup,, easy as pie,,, good deal of improvisation here,,

contrast can be dealt with by fine rotation

as I have said from outset

the contrasy of panels is set by quality and density of polarizers,, but there is a limit to high level grade, with normal backlighting methods employed thus far,,

plus I have enormous light flooding everywhere,, plus room lights on,,, never mind my PJ top off, with 400 watts flooding, room ,it light broad Bl$#@%$dy daylight here,, at 2:30 am,, and also screen brightness around image,,, hehehhe


clive

oh... is that a picture of the projection then? or the actual lcd? do you mean rotation of the polarizers?

We should back down a little and let him do his full research, and have everything ready instead of jumping to conclusions, of what is being done... this thread is moving to fast and to many questions upfront. I know it is hard to test and post at the same time.

Joe

agreed , I'm going to go back and reread marks theorizations, I can't see why removing an anti-glare layer would have anything to do with contrast changing , will wait and see exactly what elken is doing too ....

more,, this time used a tripod,,, combo of ports and 2:45am hehehheh

oh sparkles are caused by Silver Metallic in MMUDse mix,,, nice effect up close and personal,,, but thats before anyone comments...

clive.....

SWEET MOTHER OF LUMENS!!!

now thats what i'm talking about !!!!!

Think about it,,,,,,, without polarization,,, you have no contrast,,, goes with out saying,,, the better tha polarizer the better the contrast,,,,,

Refer to my first image without antiglare/polarizer,,, the image is there,,,, simply put there nothing to contrast it against,, all the little pixies are all at right levels,,

you simply dont have a point of contrast reference.. IE the POLARIZER

clive.....

Cool stuff!

But about contrast. As we all know, white is the totality of light, black is the absense of light. Whenever we increase light, blacks get greyer. When I got my venture, (which is brighter then the ushio) I had to turn the brightness down on my N6 or the image looked washed out. This may soun like defeating the purpose of a brighter bulb but its not. Colors are stronger and the image is much more intense.

So we may need to turn our brightness levels down on our tv boxes and htpc's. Really we want the bulb to take care of brightness and the lcd to just produce the colors.

MARK!!! DAMIT, DO YOU SEE THIS!

Ok consider this point,, why do all the settings in powerdvd/windvd etc etc

when they offer you choices such as tv..lcd..projection.. etc

when we use logically as we assume projection settings yuk we end up with dark image,,, well it is because the commercial units have higher lumens,,, ditto point now with this method,,, we have up'ed the anty on lumens now,, so back to settings in video codecs,,, just a settings issue,,,,, bear in mind heheh this thing as you can see is a windows 98 Lappy,,,, what can I do with that,, yuk no settings,, is as is ,,

so before jumping the gun and start knocking,, ( point generally aimed,, not at anyone person)

this is the first time we may have jumped a qantum leap, and with all the other reflector stuff happening,, and brain resolving the bigger lens,, etc

gawd we will have leapt ahead,, and something that we can be really proud of,, cause we all did it together..

heheheh oh of course Brain gets more earnings too, from increased sales...

but at the end of the day we win.....
clive...

I was asking why the anti-glare removal would affect contrast , I know the polarizer itself still needs to be there ... so I'm still confused as to what exactly you are showing us.... is it a "taped" laptop or polarization replacement ?

Sweet!

Sorry, it just took me while to get caught up here (And to sleep. ).

There seems to be some confusion about what I feel is optimal. Post http://www.lumenlab.com/forums/index.php?s...indpost&p=92105 still stands. But you will see there is definitely some flexibility here ( You haven't been private messaged something have you Mark? ). Polarizer on the triplet is not optimal do to stress birefringence at the condenser. Pressing polarizers up against panel is no good due to heat buildup at the junction.

Mark.

Geez read the posts,,,,,

This is the full test,, polarization replacement.......... The poor murdered lappy has now been bathed in da light, for it purification of its poor soul,,, and I who is the perpetrator... is doing 3:30 am penance,,, when I should have been smart and left it for ten hours as I said I would,, 7 hours ago,,,,,

mikyd: If you rotate the front and back polarizers together, away from their original orientation, does the image get compromised in any way?

Elken: The beans . Just spill the beans. You don't need to wait for me; I sleep to much (must be torturous to wait). FWIW the sleep went by pretty fast for me .

Mark.

Mark, Elken...if I could personally shake your hands and congratulate you 2 I would. Outstanding job.

Now, that you have proven that it can be done I suppose we should concentrate on what polarizer is ideal in our application. Before I or we should start 'ripping' the clothes off our panels I'd like to first determine what clothes I should dress it into.

On the otherside, I suppose you will also address the easier side to this which is the 'clear' film on top of the antiglare. What type of material, where to get them, how to apply...etc.
sim

well considering I had no idea what the original orientation was ... no ;-) I just cut the film from the front in 2 pieces held one in fornt and one in back and rotated till I got a picture which seemed the same as the rest of the panel that I hadn't touched(as far as color and brightness - this was with untaped front film though)

elken: oops sorry I missed the total replacement part, of course I thought that was the benq I was looking at in the pics too ...up way too early this morning ;-)

I second that notion simul8r and thanks to you for asking a question that had been asked before and sticking with it...goes to show you that "thats been asked a million times, it just won't work" doesn't mean you shouldn't ask one more time....

I think the only way to be sure is to get the polarizers such that they are crossed (no light gets through) then put them on either side of the panel. This should give you the sharpest picture possible. Then do a full 360 degree rotation of both at the same time and observe any changes throughout the whole rotation.

Mark.

-sniff- thanks mikyd, I just opened the door and asked where the switch for the lights were, it was Mark and Elken that came up with the textbook and raped laptop and did all the work.....EVERYBODY....PORTS ON ELKEN

Elken: The difference between one section and another is going to be exaggerated in your test setup. You need to make sure a section having just one total analyzer is brighter (the transmissivity of a polarizer is at best 80%). Hope the results are still good. .

Mark.

even I am getting confused now,,,, I am beginning to think that the stripping antiglare side and using a replacemnet polariser mounted,, I wont say just yet till I prove a couple more things,, not being coy,,, just cautious,,, is easier than adding a film to the rough surface,, maybe be hard to have without getting artifacts included,,,, there are however I am sure optical places that could do a bond for you in clean rooms with a optical glue,,, i have not had the time to check myself,, but nevertheless, I am sure it is achievable,,,, in fact i think if thats the course one took,, it would be the best way...

clive,,,, oh dear yawn

Before I or we should start 'ripping' the clothes off our panels I'd like to first determine what clothes I should dress it into.

Technically we already ripped off our lcd panels outer clothes, but know we're going all the way.

now I know why we call all things including women,,, "she"

it all comes down too,, getting their knickers off,,,, oh gawd I thought we were doing a science experiment,,,

time for me to, "go back to the future"

lolol. Removing the lcd enclosuer wasn't enough. LCD PORN FLIX COMING SOON!

Geez Mikau,, does have a sense of humour

ok new term,,,, I am sick of polarizers or as we say downunder polarisers,,


I want to call them Polar bears,,,,, I like that new term,,,


and hey someone put about ports in a post,, I was drinking one as I read it... nearly spilt it hehehehhe

Galway is my fav.... hehehhe

hey sim get a few beers,, and lets party,,,, oh well you guys can while I snore

I aint getting up till at least 1030 am melbourne time,,, gotta find some new prawns for Dazzzla,, who if he is smart is snorring up there in Bendigo,,, a ways up the road from me....

well as I said earlier if you take the front polarizer off a laptop and cut a couple of pieces of it out and affix them to sunglasses you could watch whatever you want and no-one could tell.... ;-)

Understood Elken, as you have already asked other members here to help look into what 'clear' material could be used for the easier/but not ultimate way then perhaps we should divide up the work for you. Not trying to sound like micromanaging here but we all certainly want to get the 'skinny' soon so that 'I CAN GET MY SCRATCH OFF MY PANEL'...oops, did I say that to loud

elken,

excellent work so far.

any chance at some lumen readings with and w/o tape, and with and w/o polarization replacement ? Call me an engineer, or whatever, I just like to quantify things.

we may need more cooling fans to keep our lcds from overheating.

Hey, you know...we may also be able to get 3d working on this...what do you think...DAM IF THIS IS NOT GETTING OUT OF HAND!
