Samsung prepping 7" Super AMOLED Plus display for tablets with increased resolution
0. phoneArena 01 Aug 2011, 07:41 posted on
Samsung Mobile Display recently opened its new OLED display factory, and is now rumored to upgrade the resolution of its 7" Super AMOLED display prototype to 1024x768 pixels, for eventual tablet appearance...

Battery life with AMOLED will be very badssoche Dulles. (white are consuming three times more than LCD). And AMOLED screens (and sons) are buggy.
Very bad choice.

You can keep LCD and its grey looking black images.

And with LCD you avoid to have shade of blue instead of white.

battery life on Super AMOLED+ is much improved over LCD in all areas exept for white. Its thinner, lighter, has better sunlight reflectivity by far, generally uses much less battery power, can be brighter, has better colors and infinite contrast..
yup, i can see why you prefer LCD.

Sorry for the wrong words:
Battery life with AMOLED screens will be very short, on a device that should be used a lot with internet (white are consuming three times more than LCD). And AMOLED screens (and sons) are buggy.
Very bad choice.

"Battery life with AMOLED screens will be very short..."
Actually, in this case, you are TOTTALLY WRONG, screens based on OLED technology are more battery saving than LCD screens.
But there is other side...
Screens based on OLED technology have some really essential disadvantages, for example "Burn-In" effect and short lifetime.
The biggest technical problem for OLEDs is the limited lifetime of the organic materials. Degradation of current organic compounds doesn't happen instantly! Organic compounds degradate all the time and it is only question of the time when it will be noticed. Also time of organic compounds degradation depends on some conditions.
My advice would be to improve OLED technology before releasing more OLED technology based screens into the wide world.

that degridation normally happens over a couple of years. Thats generally more than anyone will have the phone anyways. Not sure if I'd get a TV with it unless it came with a lifetime warranty against such things, but a phone/tablet is perfect for that since we replace them often.

You are wrong when you say that AMOLED burn in takes years to appear. It has taken only a few months (from 3 months) for many persons. The deterioration begins from the first day…
Look at this:
There is a lost in brightness and burn in:
You will find many other threads like this on the web.
There is a lost in brightness that is 10% for blue colour in only 100 hours of use:
The worst colour in AMOLED is blue. Scientists say that it has a very short lifespan, and that it display itself very bad.
For new AMOLED generation (Super AMOLED Plus), also appeared manufacturing defects (yellowish tint of left side, vertical line, colour circles, etc…)
Look here (thread of 186 pages continuously growing):
Hoping they will resolve them…

Degradation is always in progress, organic compounds degradate all the time and it is only question of the time when you will notice symptoms of degradation on OLED based screen!

Talking about "Burn-In" effect:
Some time ago I have searched some information about a AMOLED screens and its "Burn-In" effect and I have found a forum with a vote poll. Voted about a 200 "SAMSUNG Wave (S8500)" users and about 35% of them was telling that their screens are affected by "Burn-In" effect. And they was claiming that they have noticed "Burn-In" effect on their screens approximately after 3-4 month of usage! Also I have read that "SAMSUNG Galaxy S (I9000)" screens also relatively fast get "Burn-In" effect.
Nokia C7 - Purple Screen issue.
Nokia N8 - Purple Screen issue.
SAMSUNG Wave (S8500) - Relatively fast get "Burn-In" effect.
SAMSUNG Galaxy S (I9000) - Relatively fast get "Burn-In" effect.
SAMSUNG Galaxy S II (I9100) - Screen Yellowish problem.
Also there is other examples with other devices like TVs...
And all thise devices use screens based on OLED technology!
I don't say that OLED technology is bad, it just need more time to evolve and be improved.

What I was saying is that for WHITE colours, AMOLED use 3 times more than LCD (while they use less for other colours). On internet, you have mainly white background colours. And tablets are mainly used with internet, with major battery consumption in this case fore AMOLED. So, AMOLED doesn't seem to me the best choice in this case.
Go to Gsmarena blogs, and you will see that on their Web surfing test, Super AMOLED and Super AMOLED Plus, have the worse battery life of tested smartphones (including Iphone 4, LG Black, LG 2X, Sony Arc). Furthermore, you have to think that AMOLED (all) have 300/400 NITS brightness, when other smartphones have much more (up to 750 NITS of brightness for LG Black). Reduced brightness reduces battery life, but reduces also satisfaction and the details you can see. I personally think that battery performance in AMOLED screens is mainly due to reduced brightness for AMOLED compared to LCD.
Look at this article (yes, it's phonearena) where is published a measure for AMOLED consumption based on colour or image (You can see that for white colour, AMOLED battery life is 330% of what LCD use for the same white image !):
And, compared to this test, there are big improvements done in battery life with new LCD screens (LG Black for example).
I agree for all other comments you made.

I dunno why people bother creating tabs w/ 500ppi screens when the human eye can only distinguish up to around 300ppi. Its F**kn pointless if you ask me.

I have a nook color running cyangen off a sd card.
7" is just a little too small. Its a odd size, a bit more useful then a phone but not as useful as a 10" tablet.
Its not terrible cause its easy to hold, but I still seem "screen size" limited with certain things... just less limited then phones.
Then again haven't really USED a 10" for long periods, I just assume based of the 7" that it may be the "sweet" spot.

I know people love them but I dislike AMOLED personally.
I'll be buying a tablet with a LCD display.

OLED technology isn't bad, it just need a time to evolve and be improved.
Talking about LCD, I like LG's NOVA display. :)

10" waaaayyyyy toooooo small, why not 20"? Maybe 24"?
I love the 7" size. Been using one for months now. I could never cart around a 10" beast. Might as well carry a laptop.
18. remixfa (Posts: 14049; Member since: 19 Dec 2008)
i have the LG 8.9 For me its right about the perfect balance between screen size and portablility. The 10's seem too big and the 7s arent big enough. Its all preference though.

I just love the Super AMOLED screen on my Galaxy S. The current LCDs however just turn me off, so only an LED-equipped tab will get me to buy a tablet. Looking forward to what they can produce next year.

7 is perfect for a reading tablet. Probably not as good for a gaming tablet, but heck, people use phone for gaming and 7 is hugely bigger than 4.3.

G slate has the perfect size screen IMO :)
