Full Version: Anti-glare fused to polasheet First Layer

Ok. to my surprise the very first layer on my 15.4 widescreen lcd is a polarizer. Not sure if the the ag is fused to it but there is antiglare very obvious when looking at the front of the lcd.
Unlike other monitors i stripped there is no clear transparent layer visible at all. Either its after the pola or fused to the pola.

I was wondering if i should try a paint strip method to try to remove the ag effect of the front assuming the ag is the first thing which im not even sure.

If i do remove the polarizer will i receive the same quality by using a replacement pola and attaching via adhesive to say the first fresnel?

What make and model LCD panel do you have?
There have been some instances where an "extra" polar layer was discovered under a polar layer and antiglare layer.

As to your question about the replacement polar, check out the Google search: site:lumenlab.com replacement polar polarizer

the backlight sticker says Au Optronics Model: m150ew01
Made in China - 15.4 widescreen

Im pretty sure the very first layer on the front of the lcd is a polarizer. This is the second panel i found like this. The first one was actually and lg 1553s. The anti-glare was under the polarizer.

I think I was finally able to find the spec sheet for your LCD, unfortunately, it doesn't have any info on what polar/AG layers it has. I did see one reference to Surface Treatment: Non Glare.

Proceed, if you wish, but please document your findings. wink.gif

Thanks for your effort quasi. Im not sure what you mean by the last phrase about surface treatment. The link is just panel specs. What kind of surface treatment do you suggest before i try removing the pola and then be forced to buy others.

Previously, we have determined that polar "PVA" is sandwiched between two clear layers abbreviated as "TAC" to protect it's fibered or strand like structure. The top TAC layer's surface is either chemically or mechanically etched creating the antiglare appearance. If you found something that's embedded and of just one sheet is beyond us. Can I ask how you removed the sheet you are referring to? Is it quite thick like cardboard?

For experimental sake and If you already have the sheet removed you can try paint stripper to see if the front part of the sheet is just TAC with etching (antiglare). But I wouldn't hold hopes of reusing the sheet after your done because the process is not that easy and most especially after it's been removed from the lcd. You may want to research elken2004's threads in which he used acetone to remove the antiglare from a polar sheet but was quite a delicate. Both methods acetone and paint stripper require lightly sanding the ag prior to applying the chemicals.

Surface Treatment: Non Glare
That just means that Non Glare (antiglare) was applied to the surface.

ok. sorry for the late reply, i used water and 20% acetone to remove it. I have another panel that needs the ag treatment removed also, so it sounds like if i try this acetone or paintstripper strategy i have nothing to lose. if it does not work, i will need to get a new polarizer. Correct? Can i damage the panel at all? i mean if i use paint stripper will it ever reach the glass?

is the thread you mentioned by elken2004 something he started?

the one pola that is removed form my first panel is a thick sheet but not as thick as cardboard by any means. One side is shiny and the other is frosted so i see this would be the side to try to acetone or paintstrip it.

Im going to try this on the pola that is already removed before i try the other panel.

I resolved my problem by taking the polarizer off a damaged lcd and putting it at the triplet of a working setup. The polarizer I removed was the one on the back of the lcd and since this will be going to the front of good lcd panel I suspected it would need to be oriented 90 degrees and i was right. Worked great with the pola oriented as a 9 inches wide x 12 inches high. I experimented with the placement of this pola and i did not see any difference so i decided to place it about 3 inches from the flange of the triplet. All i did was stretch the pola sheet on a wooden frame and clamp the sheet with black metal folder clips. Since the arc is is a small hot spot of heat on the pola now it will need some cooling as to not degrade etc...

There was some confused comments about whether the pola at the back of the triplet is good or not so i`m here to say that as far as using a pola sheet that is made for lcd panels you are perfect to go this route. You will also keep your lcd cooler.

The pola on the back of my working lcd is still on there. Since it won`t affect image quality i won`t remove it and risk damage.

how does that keep the lcd cooler? if the polerizer is by the triplet, dosnt that make the lcd dark and absorb more heat. I have same issure, polerizer was attached to AG. I have a old lcd plolerizer 3-4 " above my LCD, but it seems to run hotter. Which would make sense cause the lcd is darker absorbing more heat cause there is no color on it but on the polerizer.
