NHK Showcases Thin 88-inch 8K OLED Screen And Also A Bendable OLED Too

[Paul2]

The NHK Science and Technical Research Laboratories will hold the Open House 2018 exhibition on May 24 in Japan and among the interesting products there will an 8K / 240Hz, 88-inch sheet-type 8K OLED, along with a bendable iOLED.

NHK is researching a thin, lightweight large-screen sheet-type display using organic light emitting diodes (OLEDs). The self-emissive display devices are designed to allow people enjoy 8K Super Hi-Vision's images at their homes.

NHK will be showcasing a 88-inch 8K display based-on thin glass substrates. 8K images are displayed using just a single glass panel, whereas four 4K panels were previously required. 　The 1mm panel has been manufactured by LG Display, and ASTRODESIGN, Inc. The display supports 120Hz.



In addition to the typical features of OLED displays such as high contrast and wide viewing angles, high-quality images are achieved by adding NHK's own signal processing techniques for 8K images with high luminance and wide color gamut.

NHK, in collaboration with Nippon Shokubai Co., Ltd., is also researching thin, light, and flexible displays based on organic light-emitting diode (OLED) to encourage the dissemination of 8K Super Hi-Vision displays in the home.

Conventional OLEDs are vulnerable to oxygen and moisture, so when the display is manufactured using conventional OLEDs on a plastic substrate where oxygen and moisture can easily penetrate, the number of defective pixels gradually increases. NHK expects that inverted OLEDs to have longer lifetime since they use materials that are resistant to oxygen and moisture penetration.



Other interesting news from the event include an 8K 4x-Speed Slow-Motion System and a 8K/120 Hz Video Codec for compression and transmission of 8K videos in real time.

NHK is showcasing technologies of 8K video shooting and recording at 4x speed (at frame frequency of 240 Hz) and simultaneous slow-motion instant playback at 60 Hz.

To achieve 8K image shooting at 240 Hz, NHK developed a 1.25-inch 33 megapixel CMOS image sensor with high-speed analog-to-digital converters along with high-speed cameras capable of 8K video shooting at 240 Hz.

Signals between the camera head and camera control unit (CCU) can be connected by a single camera cable. The CCU outputs 8K/240 Hz video using two U-SDI cables.

NHK developed a high-speed slow-motion replay server that can record an 8K/240 Hz video in real time and make instant slow-motion replay at 60 Hz simultaneously using video compression and solid-state drives (SSDs) parallelization techniques. This makes it possible to carry out slow-motion playback at variable speeds while shooting long programs such as sports events.

NHK is also working with FUJITSU LABORATORIES LTD. on coding technologies that compress and decompress 8K videos with a frame frequency of 120 Hz. The companies have developed the world's first 8K/120 Hz real-time video encoder and decoder that comply with the standards for 8K broadcasting.

The hardware encoder compresses 8K/120 Hz videos in real time. The encoding method is MPEG-H HEVC/H.265 Main 10 profile, and the output bitstreams comply with ARIB Standard STD-B32 Version 3.9.

The 8K/120 Hz decoder implemented by software is capable of decoding 8K/120 Hz bitstreams complying with the ARIB Standard in real time.

Wow.  88 inch 8k oled screen that is only 1 mm thick.  that is a lot thinner than current 4k 77 inch and 4k 65 inch oled screen that is about 4 mm thick.  Super Duper thin there.  Awesome!

Not to mention this 88 inch oled screen can produce 240 fps.  wow.  not sure if our human eyes can see anything beyond 75 fps and 120 fps displays are more than enough motion smoothness for our eyes to see.  And this 8k tv can handle 240 fps.  The motion will be extra ultra smooth and if cameras are recorded in a shutter speed of 1/240th of a second or faster, then there will be virtually almost no motion blur on most fast moving subjects.

Like what they said, they can slow down the recorded 240 fps to 60 fps by 4 times and watch the video in very fluid slow motion which is handy for playback of sport games.

oh, they are also working on a bendable oled screen which is also very cool too.

Correction, after i wrote that this 8k 88 inch OLED screen produces 240 Hz, today i re-read it again to realize its actually supports 120 Hz, not 240 Hz.  Which is still super smooth at 120 Hz which i believe is much faster than 75 Hz/fps that our human eyes can see.

the 240 Hz for now is for video playback possibly hardware playback, recording, and camera shooting only i think.

What's with you and TV technology?

[Paul2]

i think i am a tv and video freak.  its one of my favorite hobbies i think.

I now have a boner because you have a boner. Thanks Vid.
