Everdisplay developed a 6" 4K AMOLED display - achieving 734 PPI. This is the first 4K 6" AMOLED prototype to be demonstrated. Everdisplay says that emerging applications such as virtual reality will demand such high-resolution displays.
Everdisplay started mass producing 5" 720p AMOLED displays towards the end of 2014. The company is also developing 5.5" and 6" panels for mobile devices, a 1.4" 400x400 circular AMOLED for the wearable market and an 8" AMOLED for the automobile market.
The world's highest density display in production is Sharp's 5.5" 4K IGZO LCD display (2160x3840) - that achieves 806 PPI. The highest density AMOLED in production is SDC's 5.1" QHD (577 PPI) Super AMOLED.
In November 2014, Japan's SEL demonstrated a 2.8" 2560x1440 panel - that reaches a PPI of 1058! This is just a prototype panel at this stage, and is based on SEL's CAAS-OS (C-Axis Aligned Crystalline Oxide Semiconductor) backplane, and a WRGB structure.
Last month Samsung Display launched a new project 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 explains that this "super dimension" display will enable an "optical illusion" that will enable 3D images.
I do not know exactly, but back in Nov 2014 the company said they already achieved a design win with a Chinese mobile phone maker.
VR needs to be atleast 4K .. global update, high refresh rate and maybe high-dynamic range too... without that the first wave of VR devices will be slightly lackluster...
and what about making micro-OLEDS that? The current VR HMD's (HTC Vive, Oculus) are too big and bulky.. they need to get smaller - more like typical glasses or darkened glasses for guys who use oxy-acetylene to cut metal :)
Gosh you sound like a real expert. The first round of consumer VR devices will surely fail because you've said so.
Any info how they achieved such a high pixel density? It's my understanding that shadow masking can't pattern features small enough for this ppi.
It's extremely hard to achieve wide FOV using a microdisplay. A few years ago it was basically impossible, but thanks to some technological advancements there are some new ways to get it wider, but still not as wide as in Oculus/Vive yet.
Slightly lackluster means failing? What comment have you been reading Bob?
they claim they already have a 100 degree diagonal micro-oled prototype.. I'd say that's pretty on par with Oculus/Vive.. the thing is not many companies and researchers have been involved in large FOV optics research so we might have even more advances very soon.. as a matter of
HMZ-T1, 2011, panel type OLED made by Sony Nagoya, 0,7inch@720p. 2098ppi. Also viewfinders for camera @0.5inch
Yes, OLED microdisplays achieve a super high density... but it is not really fair to compare them to mobile-phone sized displays, the technology and applications are quite different.
If EDO has been making 6000,000 5" AMOLED panels a month since Nov 2014,what are they doing with them ? What products are using them?
