Question Super Amoled Blue Tint on Screen, no true whites?

So I don't own a captivate, but I do own another Galaxy S phone, the Vibrant.

The vibrant forums, people aren't really responding to the blue tint. So i'm wondering if you guys on the captivate have noticed that everything that should be white, such as a white broweser window, is actually tinted blue?

If this is your first smartphone you won't notice probably, but if you own a prior LCD smartphone, try putting your screens next to eachother. Does the Galaxy S look blue?

Just wondering if I have a bad unit.

thanks

SO is this just a normal native state of the Super Amoled, every Super Amoled phone is tinted blue?

If thats the case I guess thats fine, I just don't want to have a defective unit. It is kinda annoying, it is the first thing I noticed when I turned my phone on.

I've noticed the screen is tinted blue while it's off. Haven't really noticed it on white pages though.

Yes, it's normal with AMOLED and more so with Super AMOLED. The big trade off is that it produces a realistic black color which makes images look a lot better.

(Your eyes will adjust to the blue tint in time....)

Isn't actually attributed to the PenTile pixel stuff? (not so much AMOLED, but AMOLED screens that employ the PenTile tech)

I'm reading online that the blue tint may be temporary, and if your phone has it, you are actually lucky. Because, I guess the BLUE leds die out really fast compared to the rest, so Samsung on purpose made the screen to over display blue, and as time goes on, the blue will die to a yellow. So if your phone is more blue today, it will last longer tomorrow.

I don't know how true that is. Read it on some forums, that is what wikipedia says also.

Samsung tunes all of their displays (TVs and all) towards the bluer end of the spectrum because it gives the display a higher apparent brightness because our eyes perceive bluish white as being brighter than yellowish white even with no actual brightness difference.

Not my eyes, my eyes see blue white as being darker and almost gray, while yellow white is much brighter like the sun.

Blue is better than pink. My Incredible is pink. Blue is just a cooler color temperature. I can deal with that.

If there is a blueish tint to my Captivate, I neither notice it nor am affected by it, and regardless the issue would be far-outweighed by both the huge benefits of this phone, as well as much-bigger issues that need to be addressed.

If your horse has a broken leg, you don't complain about the way it smells.

many people complaint that IPS LCD panels (like the ones used by Apple lately) have yellow tint. Perhaps there is no such thing as "true whites"?

The yellow tint on iPhone 4 was temporary, it was some kind of chemical used in manufactoring that fades within days of use.

depends on how bad it smells (kidding)

If I look and really compare to bright whites I can notice it, but I don't mind it in the slightest. The color spectrum and the black levels are so much greater than my old iPhone 4 that im happy. I do notice with a few co workers iPhone 4's the pixel density and the true whites, but am far happier with the black levels than the pixel density

I only notice it when looking at it side-by-side with other phones. But, as mentioned, the true blacks and color saturation more than make up for it.

also, i just pulled off my back cover and the battery date is 07/04/2010, i dont see any posts about this date, maybe im special

p.s. battery date info is in this very similar thread: Screen tint on newer vs older Captivate

maybe a mod could just merge em?

are you talking about the actual blue background on the default skin for this forum? if so that is not what anyone is talking about, the first post in the thread linked above will show you exactly what people mean

Well a possible answer is that, according to something I heared in one of my electronics classes, there isnt any such thing as a TRUE white LED yet. Many "white" LEDs have hits of other colors, such as pink, yellow, and blue.

That seems to be confirmed by an article here:
What Is True White LED? | eHow.com

Since the AMOLED is a type of LED, maybe this could a possible explaination?

^^^ there is no white LED in AMOLED
it is RGB (red+green+blue) when all 3 leds for one pixel fire up, the colors mix and you get white color. The bluish tint might be related to Pentile RGB technology in this AMOLED. I do not notice blue tint though on my Captivate, and I got one of the first batch ones (bought at release date, first at my store).

Really? So then, for example, you think a car with standard halogen lights looks brighter than one with HIDs? Even when the halogen lights are on their brightest setting, to me the HIDs still look brighter because of their bluish-white tint.

I'm not talking about halogen car lights, I'm talking about a blue tinted led screen. I prefer warm whites, blue whites sometimes look gray and dark. Sorry just my opinion. BTW not all galaxy s phones have the blue tint problem.

You can adjust the color tone in the video player, but other parts of the phone still look blue.

AT&T sent me a replacement Captivate...which I have sent back for another replacement Captivate.
While the phone quality was much better, the screen was much worse.
On the first phone, the screen had a slight blue tint, but was very bright and I usually kept the screen less than 50%.
The second phone's screen was sooooo blue-grey, that I had to keep the screen at 100% to read text and even then it wasn't bright enough, and was rather eye-straining.
I really wish that Samsung had better quality control.

So what is the verdict on your 3rd captivate?

You know, I been looking at lots of captivates, vibrants, and now epics.

The screens vary so much. Some are blue, some are blue/green, some are warm whites, some are yellow, and some look down right dirty yellow dingy colored.

I would hate to replace my blue tint and get one that looks almost brown.

wtf samsung, why do screens vary so much!

A little away from the question but this is also a reason why forums should go for a black background (atleast for moblles). Whites are firing all color pixels to reproduce the white which eats the battery while black is much easier on the battery.

*Hint Hint*

I knew before I bought the phone that the whites have a bluish tint to them after watching tons of YouTube videos on the Captivate. It doesn't bother me at all though - I hardly notice.

there is an option in the web browser to adjust brightness settings that may help get people get used to the blue tint. I dont even notice anymore when browsing in fact it even looks quite nice!

Sorry to revive an old post, but my captivate has a weird problem. It has a square that is yellowish tint, but the border is pure white. I would be fine with it if the border was the same. But it isnt and always makes the screen look yellowish.

I have the exact same issue, yellow tint taking up 95% of the screen, and a blue tint bordering around it (about 2mm thick), it's very noticeable. I bought the phone used, so I doubt Samsung or AT&T will do anything about it, am I screwed? Is there a fix for this? Anyone else having this issue other than Caleb and I?
