Sparkle effect really caused by anti glare coating it seems

I heard some people complaining that Dell just uses cheap LCD's and that's the reason they are sparkly, well I have to say I now believe Dell and it is caused by a anti glare coating. I recently just put something called a JavoScreen on my PSP, which is a antiglare, smudge, scratch protectant for the screen and the first thing I noticed when I turned it on is that it looked identical to what I notice on the I9300 display as far as the sparkle effect. Just my 2 cents

They are using old matte-type lcds with antiglare coatings and adding a glossy coat on top.

End result = sparkle, with glare. Kinda silly :P

Yeah I guess that is quite silly, but I imagine without the anti glare coating it would be a higher degree of glare.

Dell's claim that the sparkles are from the anti-glare coating making no technical sense. The reason so many laptops have a matte finish is because that is an anti-glare technique. The glossy looking screens are not supposed to have much of any anti-glare properties.

No, it doesn't help glare any. The glare is just as bad as it is on the XBrites, which lack any type of antiglare coating and therefore have no sparkles

Are you saying there is no anti-glare property's in the screens? I believe there is and that's what causes the sparkle effect. Like I said the JavoEdge protector, and anti-glare coat I added to my PSP LCD caused the screen to look indentical to my I9300...

But the screen's you are talking about don't have any less glare because they don't have the glossy screen to make the glare appear in the first place.

So are you saying the Dell display's DO NOT or DO have a anti glare coating?

i think he's saying the anti glare finish is underneath the glossy, which doesn'y make any sense at all on dell's part.

Imagine if the put the anti glare finish on the outside glossy coat... It would look horrible... I think it really does help the glare.

Jdbaker82 I agree with your assessment that the issue is duplicated when you put a protective film over the PSP. It appears that the Dell LCD's create the sparkle effect by having a protective coating over the LCD. However, I don't believe the top glossy coat has anything to do with trying to reduce glare as it was an attempt to take an LCD and put a glossy coating for competitive reasons since Toshiba, Clevo, and Sony had one. The issue is that the LCD wasn't designed this way as it was converted to reduce costs. Dell can't publicly say "hey it looks kick ass when we ran a movie and game demo on it and nobody was smart enough to open a text pad with it since that's not the target market" So the best the PR team can come up with is sparkles=anti-glare magik coating.

I think that this sparkle effect is from the screen makers attempt to diffuse the light coming from the screen in an effort to smooth out the pixels, not to diffuse reflective light. The frosted matt finish on my 9200 screen shows no glare, probably lessens some of the sparkle intensity, but probably blurrs the picture far more than the newer screens in the 9300s with the gloss face.
In either screen, I'm certain that they both share the same "pixel-bleeding" 'technology'.
The industry has been working on filling in the gaps between the individual pixels and widening the viewing angle for years. This (I believe) was just another (cheap) approach that yeilded a compromise that was inappropriate for use where the viewer essentially has his/her face all but pressed right up against the screen. Set a detailed, sharp image on the screen, and step 4 or 5 meters away. Now walk in a 120* sweep back and forth.
The image is GREAT!

My guess is this was a great idea for a television screen, and some dumbasses figured it would be appropriate for a 17" multimedia lappie, never really understanding that viewing even the best LCD TVs from 12 inches away makes them look like crap.

I think there is a lot of conjecture on Dell "coverting" their LCD screens to a glossy screen. Thre is no evidence that Dell took pre-existing LCD screens and had a glossy coating applied. In fact, from a manufacturing perspective, it makes no sense. I would think the cost to take a finished LCD screen and put it back into the manufacturing process would be cost prohibitive.

I think someone said, that someone said, that they new someone that said that Dell added the glossy coating---and now, everyone is saying it as fact.

However, the theory seems sound, whether or not it's true. On all Lcd's I see that have anti-glare coatings I see the "sparkle effect" to some degree. So it seems that maybe that is what dell is doing. I don't really care either way myself...I do have a backlight issue that needs to be resolved though, and that is a problem more so then the sparkles. I can't believe there is so much talk over sparkles, when these backlight issues can't be so easily explained and in my eye's is a big problem. there should be no backlight leakage, kind of like this 20" dell I'm looking at now, it's about perfect for a 3 year old monitor (as far as leakage goes).

I think you are correct. I believe the "sparkle" is not a defect; but a normal product of the anti-glare technology--it is what it is. On the other hand, the light leakage is clearly an issue that needs to be addressed by the manufacturer, or Dell needs to demand a higher degree of quality control on the manufacturing process.

On a side note: I think the theory is sound that explains the light leakage as a seal around the LCD that needs to "seat" and cure before the leakage is reduced. Then again, I'm not an engineer.

I've heard it's problem that can be solved with a little burn in time (light leakage), so I am giving it a week or so to see if it get's better.....I do believe in giving it a chance to work itself out......anyone know how long I should wait before asking for a replacement?

sorry, I know it's a little OT.

3 or 4 years should do.

Yeah, that's right.
-It needs time to burn in and for the seal to seat.
