An Axon 20 5G teardown explains the under-the-OLED selfie camera technology

A couple of months ago ZTE announced the first smartphone with an under-the-OLED camera - the The Axon 20 5G. The phone is now shipping, and first reviews are quite dismal in terms of the quality of the selfie camera - and the effect on the screen.

YouTuber JerryRigEverything performed an interesting teardown of the Axon 20 5G, where he shows how the technology works - there's a small transparent OLED display right on top of the camera that is attached to the regular punch-hole display. The display in this phone is made by Visionox.

First review of the ZTE Axon 20 5G with its under-the-display camera is in

A couple of months ago ZTE announced the first smartphone with an under-the-OLED camera - the The Axon 20 5G. The phone is now shipping, and the first review is in, by The Verge.

The conclusion is rather dismal. The area in the screen under which the selfie camera resides is noticable - in fact the reviewer say that the "under-display integration is extremely noticeable on light backgrounds". You can see a square patch of the screen that exhibits a clear dithering effect. In fact the reviewer says that he'd prefer a notch-type display over what he gets in the Axon 20 5G.

The display measurements experts at DisplayMate tested a Note 20 Ultra phone, and reports that Samsung again improved its OLED display performance (it "raises the bar significantly higher", in fact) and this high performance display will be the competitive baseline for all upcoming smartphone displays.

DisplayMate: Samsung's Galaxy S20 Ultra OLED is an impressive display - the best ever mobile display

Samsung recently announced its latest flagship phone series, the Galaxy S20. Our display measurement friends from DisplayMate tested the new display - and unsurprisingly it turns out that the new Samsung Display AMOLED displays are very impressive - and they earn DisplayMate's highest ever display performance grade.

DisplayMate tested the Galaxy S20 Ultra, with its 6.9" 1440x3200 (511 PPI), 120Hz, Dynamic AMOLED display. The display has "close to text book perfect" calibration accuracy and its performance is visually indistinguishable from perfect. The new Samsung OLED display is setting or matching 12 smartphone display performance records.

Samsung launches its second foldable OLED phone, the Galaxy Z Flip

Yesterday Samsung announced the Galaxy Z Flip, its 2nd foldable smartphone, features a 6.7" 1080x2636 inward foldable HDR "Dynamic AMOLED" display. The external display is a small 1.1" 112x300 Super AMOLED. The Galaxy Z Flip will ship on February 14th, starting at $1,380 in the US.

Besides the new form factor, the Z Flip uses an ultra-thin glass cover - unlike the Galaxy Fold which used a plastic one. At least according to The Verge, this makes for a big improvement - it feels better, can't easily be "marked-up" by a fingernail and there's no visible crease. The Z Flip also feels much more refined - with no creaking and with a solid-feeling hinge.

Motorola starts shipping the foldable Razr 2019, initial reviews are here

Yesterday Motorola started shipping its $1,500 foldable OLED phone, the Razr 2019. The Razr 2019 features a 6.2" 2142x876 (21:9) foldable AMOLED display that folds inside, produced by BOE. There's also a regular external 2.7" 600x800 AMOLED used when the phone is closed.

Initial reviews are appearing online. Android Central's Nirave Gondhia tested one such phone, and he says that the Razr's screen feels fragile, even more so than the screen of his Galaxy Fold. While he likes how the device folds, he says that as the screen shifts along the hinge, the feedback on the screen feel strange and it feels as if the screen could be damaged by the folding over the long term.

CNet reviews the Huawei Mate X foldable phone - and likes it alot

Last month Huawei finally launched its first foldable smartphone, the Mate X with a 8" 2200x2480 foldable AMOLED display (produced by BOE) that folds outwards. One of the first reviews was posted by CNet's Andrew Hoyle - who spent one day with this $2,400 device - and liked it a lot.

The OLED itself seems to be a great display - Andrew says that it is a bright, vibrant and sharp display. When open, the 8" display is great for videos and images. Andrew also loves the folding mechanism works like a charm, and says that the device is a joy to use. Compared to the Galaxy Fold, he says that the Mate X is much thinner when closed which is important - and it is also much more usable when closed as it has a much larger display.

Google announces its latest Pixel smartphones with OLED displays

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.

The Fraunhofer FEP Monarch flexible transparent OLED lighting kit - hands on review

In 2018 the Fraunhofer FEP institute announced it is starting to offer a design kit that includes several flexible and transparent OLED lighting panels. The Monarch Kit includes several colored butterflies samples, and the researchers were kind enough to send us one such kit for a short review.

So first of all, these OLEDs look beautiful. They shine a beautiful uniform colored light and are very nicely done. There's not much functionality, but it shows the potential of flexible OLED lighting quite nicely.

CNet tests the Galaxy Fold and shows that it lasts 120,00 aggressive folding cycles

Samsung recently re-launched its foldable OLED smartphone, the Galaxy Fold - and now the first reviews are coming in. CNet posted an interested video in which they put the Galaxy Fold to a folding cycles test, using a what seems to be an aggressive machine that folds and unfolds it quickly.

The Galaxy Fold lasted for 14 hours - or 120,000 folds. Samsung says its own tests show that the smartphone lasts for over 200,000 folds. So the CNet test falls short of that - but I have to say that CNet's machine seems rather more aggressive than a normal folding would be...
