AU Optronics is showing off a new 5.7 inch display that could show up in future smartphones. What makes it different from most phone displays (aside from the fact that it’s rather big), is that it’s a 2560 x 1440 pixel AMOLED display, making it one of the first WQHD AMOLED screens for phones.

AUO 5.7 inch WQHD display

Samsung plans to bring a 5.2 inch WQHD AMOLED display to market soon. Technically that screen will be even sharper than the AUO screen, with 560 pixels per inch rather than 513… but once you get past 500 pixels per inch, can you really tell the difference? (Apple says it’s tough to make out individual pixels on a smartphone screen once you get more than 326 pixels per inch).

There are already a handful of LCD screens with similar display resolutions, like the displays used in the Vivo Xplay3S and Oppo Find 7.

AMOLED displays have a reputation for displaying vibrant colors and better contrast with darker shades of black — although some folks think colors on AMOLED screens look oversaturated.

LCD screens often tend to show more natural colors, but they require a backlight and can sometimes use more power and some models don’t have the wide viewing angles you get with AMOLED screens. The good news is that LCD screens often look better in direct sunlight and can be more energy efficient when the brightness is cranked all the way up.

Those are broad generalizations though, since there are a number of different types LCD available in 2014, and some phones with LCD screens may look better than others.

Still, it’s good to see that folks who are fans of AMOLED technology will soon have the same crazy high-resolution smartphone screen options that are available from LCD screens.

  1. I think what’s more interesting is that Samsung produces a pile of AMOLED screens but doesn’t share iirc, so anyone else jumping in on the market can only be a good thing (I’m amazed the Moto X managed to get a hold of some tbh)

  2. The resolution race is getting to be plain silly. I doubt anybody can tell the difference (when used normally) between 400 and 560 ppi. Driving all those pixels isn’t easy either. You need a very capable GPU and a lot of power. Not good for battery life. Who knows, maybe they plan on using all that resolution to make 3D phone screens? Can’t you just see people walking around wearing 3D glasses, staring at their phones?

  3. I think OLED is cool since it does not require a backlight and more current versions are flexible. There are even OLED screens that are transparent. I think it is an excellent alternative to LCD screens.
