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.

In 2015, NTHU started to develop its low blue-light candle-light orange-type OLED technology, initially in collaboration with Wisechip and later with China-based OLED lighting producer First-o-lite.

UDC: our RGB1B2 AMOLED architecture minimizes blue light hazard

In 2010 Universal Display announced a new AMOLED display architecture called RGB1B2 that uses two blue sub-pixels - a fluorescent deep-blue and a phosphorescent light blue. The introduction of a light blue sub-pixel can significantly extend the operational lifetime of an OLED display and reduce the display's power consumption by as much as 33%.

The RGB1B2 was never adopted (one of the reasons is that adding another sub pixel complicates the TFT backplane and has other disadvantages - but the architecture is now again on the table and UDC presented it again at OLED Korea 2019.

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.

Broken Galaxy Fold screen, The Verge

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 Display 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.
