Samsung LogoSamsung Display announced it launched a new project (called EnDK) to develop the world's first 11K mobile display, that will achieve 2250 PPI(!). The Korean government will support this five-year project with a $26.5 million grant. Samsung is collaborating with 13 companies on this project, and they expect to show the first prototype by the 2018 Pyeongchang Winter Olympics.

This seems crazy at first for a mobile device - after all the human eye cannot physically distinguish a higher than 2K resolution in a mobile phone. But Samsung explains that this "super dimension" display will enable an "optical illusion" that will enable 3D images.

It's not actually clear if the display will be an OLED one, but it's highly likely. Samsung's current highest-density OLED in production is the 5.1" QHD (2560x1440, 577 PPI) Super AMOLED display used in the GS6. Samsung is also rumored to be developing a 5.9" UHD display for the upcoming Galaxy Note 5 - and if true it will achieve a 746 PPI.

The world's highest density display is Sharp's 5.5" UHD (4K) IGZO LCD display (2160x3840) - that achieves 806 PPI. In November 2014, Japan's SEL demonstrated a 2.8" 2560x1440 panel prototype - that reaches a PPI of 1058. This prototype panel is based on SEL's CAAS-OS (C-Axis Aligned Crystalline Oxide Semiconductor) backplane, and a WRGB structure.

Human eye can distinguish maximum 2190 ppi at 4 inches

When 1080p where the highest resolution on a smartphone everybody said that the human eye cannot distinguish more than that, now everybody says the same thing about 2k displays. I tested with white pixels on black background and with black pixels on white background in the same image on LG G3 and I spotted the pixels easily from arms length. So 2k is far from the highest resolution that the human eye can distinguish(I am not an eagle).

Here is an article that explains what is the highest resolution that the best human eye is able to distinguish: http://wolfcrow.com/blog/notes-by-dr-optoglass-the-resolution-of-the-human-eye/

Virtual Reality

These high-resolution displays seems unnecessary for mobile phones, but virtual reality devices like Oculus will surely appreciate it.

Firstly, 1080p and 2k

Firstly, 1080p and 2k resolution are the same thing, a 1920x1080 resolution screen. The i/p resolutions refer to vertical resolution while the 2k/4k/8k measure the horizontal resolution.

Secondly, a single dot is not a great way to tell whether you can see a single pixel, or just the blur of a single pixel. You should be able to see a single pixel when it is significantly smaller than the "resolution" of a human eye. Sampling theory, and aliasing in this case, is probably a bit to much to put into a reply post. However, a better test would be to have vertical stripes one pixel wide and see at what distance you can distinguish individual lines and at what distance they appear as a grey blur.

Cut the crap Samsung, where

Cut the crap Samsung, where are the monitors and TVs ????

would you ever expect your

would you ever expect your monitor to burn after one-day use?

2k mistake

Sorry about that, I meant qhd resolution from the LG G3 smartphone. As I can remember I've put some small lines(1 pixel width) on the black background and I could see those lines even better than the single pixels. It's interesting that you say that we should be able to see a white pixel on a black background even if it is smaller than the "resolution" of the human eye, could you please explain this? Thank you, have a nice day!

samsung develop a 11k mobile

samsung develop a 11k mobile display primary for VR and not particulary for mobile phones or "3D" on mobile phones. cuz everyone who tried a VR-glasses like Oculus or Samsung-Grear knows that the biggest problem is the weak resolution of todays mobile displays. and i predict thats VR is the next big thing. it means siting in a train and playing games or watching movies in 3D in front of a cinema scale screen in HD.
