Korea's ETNews reports that Samsung has shipped foldable OLED display samples to both Apple And Google. According to the report, the displays sent to Apple were 7.2" in size (just slightly smaller than the Galaxy Fold OLED display).

This is hardly a surprise - it's highly likely that all smartphone brands are now looking into foldable displays for next generation devices - and all leading brands are also likely to want to design prototypes and start looking at displays.

As OLED is an emissive display technology, an OLED pixel only draws power when it is used - and the brighter it is, the more power it consumers. This of course means that adopting a dark UI is better for your device's power life.

During Google's recent Android Dev Summit, the company detailed the power consumption of the OLED display used in its 2016 Pixel smartphone (an SDC FHD 5" AMOLED). As you can see in the image above, the power consumption is different for each color (with red being the most efficient color and blue the least efficient). Surprisingly the display draws quite a bit of power even when completely black.

Officials from SID reported that 369 Apple employees attended Displayweek this year - a 30% increase over last year. And indeed I can say that you could see Apple's employees all over the show. It's clear that Apple is increasingly interested in next-generation display technologies - including OLED displays, Micro-LED displays and foldable technologies.

SID further says that this year 40 Google employees, 25 Amazon employees and 23 Oculus employees attended the show. The display is an extremely important part of most mobile devices today, and TIer-1 producers want more and more control on the display type, quality and performance.

Google's Pixel 2 XL (which started shipping in October 2017) is one of the first two phones to adopt LG Display's new 6" 1440x2880 (538 PPI) pOLEDs (alongside with LG's own V30). While on paper these displays are superb, actual reviews were rather dismal - as both reviewers and customers complained about bad color reproduction, graininess and problematic viewing angles. In addition many users seem to report serious image retention issues.

According to reports in 2017, LGD faced very low yields at its 6-Gen E5 line, and so had to produce these smartphone displays at its Gen-4.5 flexible AMOLED line. Some users are now saying that these issues do not plague all of Google's phone - and some come with noticeable better displays. This should be good news for LGD and it's likely that as the company gains more experience with smartphone pOLED production, it will produce better looking displays in better yields.
