It would seem that the OLED panel on the X1 Yoga is actually using a non-standard sub-pixel arrangement:

Therefore one of the supposed benefits of Samsung RGB OLED over LG's WOLED is not actually true.

In more PC-related OLED news...

Quote:
For the utilization of OLED in the medical care sector, Kwon said, “The monitor division at LG Electronics is planning to start expanding the medical monitor business, including ultra high definition medical monitors, from the end of this year."
They're obviously starting at the high-end with those medical monitors, but that still confirms the manufacturing of medium-sized UHD panels which would be necessary for professional and eventually consumer monitors.

That combined with their demonstration of HFR tells me that an LG-made 120Hz UHD OLED monitor is all but confirmed to exist at some point in the future.

Sorry to always rain on your parade but...

Those medical monitors are priced in the same range as Sony's broadcast OLED monitors or even higher. They also sell in similar tiny numbers. Are you expecting Sony to also sell OLED consumer monitors soon? You need panels targeted at large volume markets before you see prices trickle down to consumer level.

HFR has nothing to do with computer monitors. They are testing HFR for IPTV streaming of sporting events. All current OLEDs already run at 120Hz but you can't feed that via HDMI due to bandwidth limitations. Doubtful LG will ever add Displayport. HFR is basically a streaming-only format for the foreseeable future.

Where did I use the word "soon"?

Besides, not only did I mention professional monitors which Sony does sell along-side their broadcast monitors but I even specifically used the word "eventually" with regards to consumer-level monitors.

It's also worth mentioning that, unlike Sony, LG Display one of if not the largest manufacturer of consumer laptop & monitor-sized LCD panels. Considering that Samsung is starting to expand up-market from phones & tablets to laptops & monitors with their own OLED panels, it would be of no surprise if LG started expanding down-market with OLED to try to prevent Samsung from encroaching on their market share of laptop & monitor-sized panels.

...which would still require 120Hz broadcast and/or professional monitors for, you know, monitoring.

HDMI 2.0 has the bandwidth to do UHD 120Hz 8bit at 4:2:0 and theoretically UHD 100Hz 10bit at 4:2:0. Last time I checked practically all digital video used 4:2:0 chroma subsampling.

Again, broadcast and professional monitors; 4:4:4 chroma is quite important in the PC space.

The case of OLED monitors for general public is weak. For professional apps there is a niche.

By that logic... "The case of OLED laptops for general public is weak."

Yet they exist.

Impulse drive or PWM in new OLEDs?

I noticed in this video of the Panasonic prototype, starting about 1:20, there appears to be PWM/pulse drive artifacts captured.
Could future OLEDs be pulse driven? Or maybe just using PWM for dimming.
