Wisechip discusses its Hyperfluoresence TADF PMOLED with OLED-Info

On October 2019, Taiwan’s Wisechip launched the world’s first commercial Hyperfluorescence™ OLED display – based on materials by Kyulux. Last month, Kyulux announced that it started to ship its emitter materials for Wisechip, who is starting to ship these displays to customers.

Yesterday OLED-Info posted an interview with Wisechip’s VP of R&D, Dr. York Tsai. Dr. Tsai reveals that the 2.7″ 128×64 TADF PMOLED is mostly aimed towards industrial products, where there is a clear need for higher brightness. The HF PMOLED offers up to 2.5 times the brightness compared to Wisechip’s fluorescence PMOLEDs. Dr. Tsai also reveals that Wisechip is planning to release more displays that utilize Kyulux’s Hyperfluorescence materials.

Wisechip’s Hyperfluorescence PMOLED demo kit presented at OPERA showroom

In October 2019 Wisechip launched the world’s first Hyperfluorescence™/TADF enabled PMOLED panel, a 2.7″ 128×64 220-nits yellow display. Kyulux’s CEO, Junji Adachi, presented Wisechip’s demonstration kit for this new panel to Prof. Chihaya Adachi (Professor of Kyushu University and Technical Advisor of Kyulux).

The new Wisechip Hyperfluorescence™ demo kit will be on display at OPERA’s showroom (at the first floor of OPERA building).

Is Hyperfluorescence ready for AMOLED adoption?

Two weeks ago we announced a collaboration with WiseChip Semiconductor to use Hyperfluorescence emitters in WiseChip’s PMOLED displays. In early July, Wisechip demonstrated a working yellow monochrome prototype – with commercial production expected by the end of 2017 for both yellow and green displays.

Hyperfluorescence emitters enabled WiseChip to boost the efficiency by around 50% while still maintaining the color purity and a lifetime of over 30,000 hours (LT50).

Following this announcement, questions were raised as to the relevance of this technology for use in AMOLED displays, which represents a much larger market ($20 billion in 2017 and continue to grow fast compared to PMOLEDs’ $0.5 – 1 billion). Even though one should not rush to discount the PMOLEDs market, which is expected to stay relevant and grow (with the rise of wearables and introduction of flexible and transparent displays), it is clear that the AMOLED segment of the market remains dominant. In this article, we set out to clarify the difference between the two technologies and lift any doubt regarding the readiness of HF technology for AMOLED displays.
