According to a new report by The Elec, Samsung displays for Apple's upcoming iPhone 15 phone series will use the same material stack (M12) that were used in the iPhone 14. The M12 was used in the upper-range iPhones 14 series, but this year in the iPhone 15 series, all four models will use the same material stack.

The Elec also says that Samsung's next foldable phones will also use the same M12 stack, used in the previous generation foldables (Galaxy Z Fold 4 and Galaxy Z Flip 4).

DSSC says that more smartphone makers will join the foldable phone market in 2023, with 37 new models introduced (up from 19 in 2022) - including new models from Google and OnePlus. DSSC says at least 16 new clamshell phones will be released, at least 20 in-folding type and one new out-folding device.

Looking at foldable smartphone shipments, DSSC says that the market will grow 45% to reach 18.6 million units, as performance increases and price decreases.

The COVID-19 pandemic created an increased demand for high quality IT solutions, including monitors and collaborative tools, which prompted OLED display makers to start offering solutions for this market for applications like computer monitors, signage and more.

OLED displays that are 20-inch or more suffer from incompatibility with standard capacitive touch, because the thin OLED panel results in large parasitic capacitive coupling with the touch surface. The dynamic driving of OLEDs (where only lit pixels draw current) further reduces the capacitive touch performance by introducing unpredictable “display pattern noise”. These issues are easily mitigated in small area displays, but as OLEDs increase in size, the performance and costs of capacitive solutions suffer.

Korea's The Elec says that it has learned that Samsung display is developing in-folding OLED displays for Google, Xiaomi and Oppo.

Xiaomi, who has in the past shown prototypes that use Visionox out-folding displays, is now aiming to adopt an SDC in-folding display - 8.03" in size. The Elec says that the same phone will use a large 6.38-inch external display, which will be produced by both SDC CSoT.

Update: Google has removed the P-OLED brand name from their web site - this could have been a mistake, and now we do not know whether these are LGD's displays or not.

Google announced its fourth-generation Android smartphone, the Google Pixel 4, that features a 90Hz 5.7" 1080x2280 (444 PPI) OLED. The Pixel 4 XL features a larger 90Hz 6.3" 1440x3040 (537 PPI) AMOLED display.

Display measurement experts DisplayMate reviewed the display and found that it is a state-of-the-art flexible OLED display that sets or matches several records, including the highest absolute color accuracy, the lowest screen reflectance and the smallest brightness variation with viewing angle.

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.

Google's 2017 Pixel 2 XL was one of the first phones to adopt LG Display's pOLEDs (6" 1440x2880) - and initial reviews of the display were rather dismal - as both reviewers and customers complained about bad color reproduction, graininess and problematic viewing angles. Many users also reported serious image retention issues.

In 2017, Google used Samsung's Super AMOLED displays in the smaller in 2017. This year, for the 2018 Google Pixel 3, Google chose SDC's 6.3" 1440x2960 Super AMOLED for the larger Pixel 3 XL - with proved to be a top-notch display. For the smaller Pixel 3, Google picked LG Display's 5.5" 1080x2160 - probably hoping that LGD managed to improve its displays - and most importantly its quality controls.

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.

Display measurement experts Display Mate posted an in-depth review of the Google Pixel 3 XL 6.3" 1440x2960 AMOLED display. The display wins DisplayMate's highest ever Overall Display Assessment Grade of A+ together with a DisplayMate Best Smartphone Display Award.

DisplayMate says that Google now joins Apple and Samsung as the top tier of smartphone displays. The Google 3 XL display is on par with the AMOLED display used in Samsung's Galaxy S9. Interestingly, it turns out that Samsung Display provides this 6.3" AMOLED display to the Pixel 3 XL, while LG Display is likely to be the supplier for the smaller 5.5" 1080x2160 display used in the Pixel 3.

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.
