Lenovo demonstrates a foldable 13.3" Windows laptop

Update: LGD confirms it is supplying the 13.3" foldable OLEDs to Lenovo's prototypes.

Lenovo demonstrated a prototype foldable ThinkPad laptop, that features a 13.3" foldable OLED display. Lenovo says that it developed this device for over three years, and hopes to launched a commercial one in 2020.

The reporters at The Verge really liked the device, but noted that the hardware is clearly not finished - the folding mechanism for example did not feel sturdy (and we all know this is critical in a foldable device) and the display itself suffers from "remarkably poor viewing angles".

iFixit review provides a possible reason why some Galaxy Fold screen failed

The teardown experts at iFixit reviewed the Galaxy Fold and have taken it apart as they usually do with new smartphone - to find out why some of early review units failed so quickly (which caused Samsung to delay the launch of their highly anticipated foldable phone).

According to their analysis, the Galaxy Fold design has a weakness - and dust or other particles could enter the phone through the gaps in the top, bottom and the back of the device. This could create "bumps" on the display as the foldable display is pressed against the backside of the phone when fully folded. iFixit speculates that this could be the cause of the some of the reported display failures (another possible problem could be the removal of the protective top polyimide film).

NTHU and First-o-lite Candle-light OLED lamp - hands on review

NTHU professor Jou has been researching the hazards of blue light for many years, warning us against the hazards of modern lighting and focusing on OLED lighting as the technology that enables low blue-light emission lighting.

AnandTech: Huawei uses panels from LGD and BOE in the P30 Pro

Last month Huawei launched its P30 and P30 Pro smartphones (with a 6.1" 1080x2340 AMOLED on the P30 and a 6.47" 1080x2340 AMOLED on the P30 Pro). Reports from China suggested that Huawei adopted SDC AMOLED for the P30 and BOE-made panels on the P30 Pro.

According to Anandtech, who posted an extensive review of the P30 and P30, the supplier for the smaller 6.1" AMOLED on the P30 is indeed Samsung Display, but Huawei uses both LG Display and BOE as suppliesr for the large 6.47" AMOLED on the P30 Pro.

Foldgate? Galaxy Fold reviewers complain of broken screens, Samsung responds

Only yesterday we reported that early reviews of the Galaxy Fold are very positive and that Samsung says there's overwhelming demand for the new foldable device - and today we have much less positive news.

At least 4 early Galaxy Fold reviewers report that only after one day of use, the screens on their devices broke. The Verge's Dieter Bohn says that a bump appeared on the crease of the phone, which quickly broke the screen - even though he did not perform any stress tests or anything - just normal phone use.

Samsung says there's overwhelming demand for the Galaxy Fold, T3 says it could truly change smartphone design

Samsung Electronics started to accept pre-orders for the Galaxy Fold a few days ago (April 14th) - and the company says it is already sold out due to "overwhelming demand" and it is no longer taking pre-orders

This is great news, especially as many questioned whether customers will be willing to pay $2,000 for a foldable smartphone. Of course Samsung's foldable OLED production capacity is limited so this demand may not be actually very high.

Users complain about the quality of LGD's pOLED used in the Google's Pixel 3

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.

The Washington Post mistakenly blame OLEDs for low battery life in 2018 smartphones

The Washington Post's Geoffrey A. Fowler posted an interesting article in which he details how new smartphones are under-performing older ones in terms of battery life. Geoffrey puts 12 smartphones to the same test, and checks which ones dies first.

It is interesting that the new 2018 smartphones under performs similar smartphones released in 2017. Geoffrey's conclusion is that new display technology - high resolution OLEDs, are the culprit. The main reasoning behind that is that the iPhone XR (with its LCD display) performs better than the iPhone XS, even though the XR has a smaller display.

Some Huawei Mate 20 Pro users compain of green tint on the BOE AMOLED display

A few days ago Huawei started shipping the Mate 20 Pro with its 6.39" 1440x3120 (538 PPI) AMOLED display made by BOE. The phone is only shipping in China at the moment, but some users are complaining about a green tint issue.

This seems to be a similar issue that happened on some of Apple's iPhone X OLED displays (which are produced by Samsung Display).

DisplayMate: the Google Pixel 3 XL AMOLED is made by SDC, is a top-notch smartphone display

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.
