LG replaces the OLED TV at Incheon airport to an LCD due to burn-in issues

Only four months after LG installed 69 OLED TVs at Seoul's Incheon Airport it was reported that the TVs suffer serious permanent image-retention, or burn-in. ZDNet now reports that LG replaced the problematic OLED TVs at the airport's Korean Air Miler Club Lounge with LCDs.

The report suggests that LG was not sure it could solve the burn-in issues with this particular display, and so opted for an LCD. LG denies that burn-in is a serious issues and says the TVs's lifetime are over 30,000 hours.

Visionox demonstrate its first transparent OLED at SID 2018

China PMOLED and AMOLED producer Visionox demonstrated its first transparent OLED at SID Displayweek, a small transparent blue panel (60% transmittance).

The tag next to the display said this was a transparent AMOLED, but it is more likely that it was a PMOLED display - after all it was a simple monochrome blue one. In any case it is great to see Visionox developing transparent displays, in addition to the other next generation technologies it demonstrated at DisplayWeek.

Visionox unveils a blue TASF OLED prototype display

Thermal activation sensitized fluorescence, or TASF, is a new type of TADF OLED emitter material developed at China's Tsinghua University. During SID Displayweek, Visionox demonstrated the first TASF prototype display.

We do not have a lot of information on this new emitter technology, except what Visionox provided at the conference: a sky-blue color (468 nm, CIE: 0.153, 0.201), a luminous efficiency of 26.6 cd/A and an external quantum efficiency of over 17%. The brightness of this OLED PMOLED display was 800 nits.

IHS: notch-type OLEDs cost 25% higher than regular OLEDs, due to yield loss

IHS estimates that a notch-design increases the production cost of a smartphone display (whether LCD or OLED) by more than 20%. A notch-type 5.9" OLED (like in the iPhone X) costs $29, 25% higher than the cost of a regular 5.8" OLED.

IHS explains that cutting the notch results in yield loss, which is the main driver of the higher costs (the panel itself, of course, is also larger before cutting the notch in the comparison IHS makes). In theory, cutting a plastic OLED is easier than the glass-based LCDs, and IHS forecasts that manufacturing costs for notch OLEDs will fall far more rapidly than the costs of notch LCDs.

Visionox starts producing flexible OLEDs at its 6-Gen fab in Hebei

China-based OLED producer Visionox announced that it started to produce flexible AMOLED displays at its new 6-Gen OLED fab, in Hebei Province. The new line has a monthly capacity of 30,000 substrates (although it is likely that it will take some time before the new fab runs at full capacity).
