Idemitsu Kosan developed the world's most efficient fluorescent blue OLED emitter system

Idemitsu Kosan announced that it has developed the world's most efficient blue fluorescence OLED emitter system. Idemitsu's new system achieves an EQE of 14% (at current density of 10 mA/cm2), a lifetime of over 400 hours (LT95 @ 50 mA/cm2) and a color point of (0.14,0.08).

The new material system uses a tandem structure of two blue OLED emitter layers. Idemitsu says that by separating the region that causes charge recombination and utilizing TTF (Triplet-Triplet Fusion) it managed to achieve the high light output.

Japan Display announces a breakthrough lithographic-based OLED production method

Japan Display (JDI) announced that it has developed a new OLED deposition technology, which they refer to as eLEAP, that is cost effective and can be used to create OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM). eLEAP also enables OLED freeform deposition. JDI regards its new technology as a " historic breakthrough in display technology".

eLEAP is based on a lithographic method, and does not require any masks. The main advantage seems to be that OLED displays produced by eLEAP technology can achieve an aperture ratio of 60%, compared with FMM OLEDs which achieve a ratio of about 28%. This means that the OLED displays can be driven at lower currents - which extends the lifetime, improves the efficiency and also enables higher-peak brightness when needed.

Here is BOE's 12.5" flexible transparent OLED display prototype

BOE is showing a new flexible and transparent display prototype at SID Displayweek, this is something we did not see for several years.

The display on show is a 12.5" panel that offers a transmittance of up to 45%. The brightness is 700 nits, and the pixel density is 80 PPI. BOE says it developed a unique pixel scheme to enable the transparency of this display.

A study by LG Display shows that OLED is the optimal gaming display technology

LG Display says that according to an original research it has conducted, OLED is the optical gaming display technology.
