OLED or TFT - How to tell?

[Guest gingerbeardman]

I think the easiest way to tell is that TFT has pixels arranged in perfect rows and columns and OLED has them in an, offset brick-wall/cross-hatch sort of way.

Here's a photo of my OLED screen.

After having bought some TFT-equipped Swiss OSFs I received two British OLED ones today, so I could make the attached photos for comparison.

With a magnifying glass you can recognize an OLED display by the staggered arrangement of the pixel lines, while on TFT displays lines are aligend rectangularly.

With the naked eye you'll notice the backlight behind black areas, which remains absolutely dark on OLED.

The TFT display is a bit brighter, but colour fidelity is worse. While TFT has a strong bluish cast, colours appear much more natural and vivid on OLED. The OLED also seems to have a broader range of colours, which you can see on the photo of the lock screen, whose background is dominated by black on the TFT, as it can't display all the nuances which the OLED displays. However the TFT is sharper - especially text loses sharpness due to the staggered pixel arrangement. As an example for this effect have a look at the edges of the icons on the close-up photo: While the edges of the icons are straight on the TFT, edges on the OLED are in a zigzag-pattern. Anyway, the difference in sharpness is nearly indiscernible from the distance and negligible in everyday life. But on the other hand viewing angles are better on the OLED, as colours are distorted much later and less than on TFT.

The only thing untested so far is readability under direct sunlight, where I expect the TFT to perform better.

This post rocks. Thank you so much.

Just looked at mine. Build is B10; LCD?

[Guest Phoenix Silver]

anyway best way to see if is it tft or oled

in complete dark

if you have backlight it's tft

Dial *983*24474636# into the phone (STOCK ROM only) and if it says Samsung then it is a OLED, if it says TRULY or LEAD it is TFT.... end of
