2 Zte Blade Oleds, but displays look different

[Guest gamba66]

Hi, ive bought a ZTE Blade with an oled display a while ago used. It has that slight red/pinkish tint that some people talk about, and it has those awesome sparkly greens and other colors..

Now I just got a second ZTE Blade thats supposedly also an OLED one, but it looks very different. It has the Modaco Rom r12 and is rooted and everything, but when i turn the brightness down, there is no red tint, it looks different but the black is still very black..

My original Blade has the jellyfish rls9

How can I check now if its really TFT or OLED, Ive read about the chipertest.apk but its missing in both of my roms, the commands are not working..

Which way can I check now if its 100 percently an OLED display. This is very important because I only wanted a second oled one and i payed a bit more for it (its for my brother)

Thanks in advance

Compare the two in a dark room displaying a black background, if you can compare it to anything with a TFT display

You should be able to tell instantly :(

Oh and my OLED doesn't have this "Pink Tint" that everyone complains about, and I got one of the original displays :(

How did you get your second one. If it was from orange rescently, it is pretty much guarenteed to be LCD.

[Guest gamba66]

i bought it used, its one from orange but from last year ..

it was titled as oled

ill try in a dark room thanks i think its oled anyways, just the red tint is totally gone.. seems there are different types of oleds maybe.. but the colors still look very good

If you can't tell the difference what does it matter? :(

I thought all the OLED ones got a red tint at low brightness.

Pink tint at low brightness is an OLED "feature".

My earlier post:

OLED active (lit) pixels require power. Therefore the "lighter" or "brighter" the image, the more power consumed. White requires the most, because you are using 3 OLED pixels (Red/Green/Blue) at once. This is also the reason why the OLED displays whites with varying hues dependant on the brightness, the RGB mix shifts slightly by different amounts as the pixels are dimmed. OLEDs tend to show whites with a pinkish hue as the brightness decreases due to the slight dominance of the red OLED pixel element. TFTs tend to have a slightly bluish tint, which is generally consistent irrespective of the screen brightness. This is probably due to the fact that white LEDs are made from blue LEDs with a yellow phosphor to convert the blue light to white. The blue is still somewhat dominant, particularly with the cheaper "cool white" LEDs used for backlights (they are also more efficient than "neutral" white or "warm" white LEDs).

TFT hasn't the same issue in terms of image shade, but the brighter ANY image, dark or light, the more power consumed by the LED backlights. If that makes sense..

I always use a dark wallpaper and auto brightness on my OLED - just auto brightness on the TFT. Some folk just set the brightness to a set level....

Unfortunately, one of the things ALWAYS overlooked by "Devs" is the poor AB control, which is easy to correct in framework-res, although the same array points give different brightness levela on OLED and TFT glass... but not by much.

My understanding is that OLEDs don't need to be backlit, TFTs do.

Therefore turn the brightness up to maximum and use something like gallery to show a completely black image.

Compare both in the dark, the TFT should still be glowing.

[Guest gamba66]

I did compare them alot in the dark, they are surely both OLED, not a trace of backlight and the greens and reds look very intensive (angry birds) on both of em!

Both have slight red tint to them but my first one has alot more (but still not distracting).. Maybe my one is just used more ?

Thanks everybody!

It' possible that they are identical and that one of them has aged more than the other. One of the biggest engineering challenges of making OLED screens is the fact that some colours fade faster than others. The SF OLED screens have a pentile matrix (search this forum) - to try to abate this problem, but I imagine they naturally change tint over time, and that is what you are seeing.
