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.

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
