UL awards Samsung's laptop AMOLED displays with its GREENGUARD Gold Certificate for low chemical emissions
Samsung Display announced that its latest AMOLED laptop displays achieved UL's GREENGUARD Gold Certification for low chemical emissions. This is the first laptop display to achieve this certification (UL 2819).

This certification is awarded to products such as electronic and medical equipment that meet its volatile organic compounds (VOCs) and particle emission standards. With LCDs, the backlighting unit can be a major VOC origin due to its use of multiple plastic substrate sheets. According to UL, Samsung's OLED panels reduced the emission of VOCs to about half of LCD's emission.
Some Apple iPad Pro users complain of 'blooming' in the mini LED display
Apple's latest iPad Pro tablets use a mini-LED backlit LCD (which Apple refers to as Liquid Retina XDR). This relatively new display technology is seen as a way to achieve almost OLED-quality contrast ratio and an improved power consumption as the thousands of small LEDs enable very small dimming zones.
While most reviews of the new display are quite positive, some users are complaining of "blooming" - the edges of bright objects on dark backgrounds tend to 'bleed' as the dimming zone is not small enough.
Samsung Display to convert an LCD fab to a 6-Gen flexible OLED production line in a $2.7 billion investment
According to reports from Korea, Samsung Display plans to build a new 6-Gen flexible OLED line. The new line will replace a current LCD line that is used to produce TVs at SDC's Asan plant (the LCD 7-2).
The new fab, which will cost around 3 trillion Won ($2.7 billion USD) will have a monthly capacity of 30,000 monthly substrates. This will increase SDC's AMOLED production capacity to 195,000 monthly substrates, not counting its upcoming QD-OLED production line.
New OLED gadget: Lenovo Pad Pro
Lenovo's Pad Pro tablet features a 11.5-inch 90Hz HDR10 1600x2560 AMOLED display, a Qualcomm Snapdragon 870 chipset, 6 GB of RAM, 128 GB of storage and a microSDXC slot.

The Pad Pro will ship by June 2021 for around $400.
Kyulux reveals its latest TADF material performance
During SID Display Week 2021, Kyulux detailed its latest TADF material performance. The red and green materials are "close to commercialization", and the company reports "excellent progress" with its blue emitter.
Using simulations, Kyulux shows how its Hyperfluorescence system is more efficient than a comparable phosphorescence emitter. While both emitters feature pretty much the same EQE, the narrow spectrum of the HF system which results in higher light intensity and can enable more efficient displays - by around 10%, according to Kyulux.
