有機EL材料業界で特許の帝王として君臨しているユニバーサルディスプレイ（UDC）が、ビーエーエスエフ(BASF)の有機EL関連の特許を米ドル約9,600万ドルで買収したと28日発表した。

この特許ポートフォリオは、主に有機ELりん光材料に対するもので、既に出願された500件を超える特許とまだ出願前の86件の特許も含む。BASFのこの有機ELポートフォリオは、平均で10年間有効である。

UDCは、今回のBASF社の特許買収により、ブルー発光システムを開発するために役立つことを期待している。今回の買収でUDCは、4,000件を超える出願特許と待機中の特許を保有することになる。UDCは、米ドル3億9,570万ドルの現金を持っており、今回のIP買収の費用は十分に可能である。

今回のUDCの動きは、韓国の有機EL発光材料メーカーも注目している。有機EL材料市場は、特許競争力が左右するので、十分なIP確保が重要だからである。

UBIリサーチの調査によると、UDCは、このような特許競争力を前面に出して、2015年は前年に続いて、世界の有機EL発光材料市場で1位を占めた。徳山ネオルックスなど、韓国の材料メーカーは、UDCの強固な市場の先取りに対抗して、特許競争力の確保に積極的に乗り出している。

成均館大学高分子工学部イ・ジュンヨプ教授は、4月に開かれたフォーラムで、「UDCの特許は、これまで訴訟を経てやや縮小された部分もあるが、いまだりん光材料がほとんどすべて含まれる広いクレームを持っている」とし、「UDCは別の特許を買収するなどの対応に乗り出し、韓国メーカーもこれに対する対応策を探さなければならない」と強調した。

一方、BASFは、2015年には有機EL関連の研究開発を中断している。

Galaxy S Series Luminance Increase Trend Shows Blue Materials Luminance Needs to be Improved by 3.7 Times

If the Galaxy S Series luminance increase trend continues, it is estimated that the luminance will reach 754 nits within 2-3 years. In order to produce Galaxy S with 754 nits, the luminance of blue emitting materials, that will be used for the product’s AMOLED, is analyzed to require improvement by approx. 3.7 times.

According to AMOLED Characteristics Analysis Report of Galaxy S Series, published by UBI Research, the analysis of luminance increase trend of Galaxy products from S4 released in 2013 shows Galaxy S series with full white luminance of 430 nits and peak white of 754 nits is expected to be produced within 2-3 years. The Galaxy S4 luminance is 338 nits (peak white), and the luminance increased to S7’s 505 nits via S5 and S6’s 400 nits mark. Calculating based on this trend, the future product is analyzed to have 754 nits of luminance.

The report reveals that for Galaxy S7, the luminance of red materials is 142 nits, green 338 nits, and blue 26 nits. To actualize 754 nits screen, the red materials have to improve luminance by approximately 1.5 times, green 1.2 times, and blue 3.7 times. UBI Research explained that for high resolution screen with limited size, emitting materials performance improvement is a must and that technology development should be focused on blue emitting materials.

CYNORA, significant progress in blue materials for OLEDs…EQE 16.3%

CYNORA, a leader in TADF (thermally activated delayed fluorescence) materials, has made significant progress in its highly efficient blue material developments during the last 6 months: a strong indicator for reaching performance levels requested by the OLED industry.

CYNORA has been working on organic TADF emitting materials during the last 5 years.

Since 2015, CYNORA applies its experience to develop pure organic highly efficient blue dopants for vacuum deposition.

The TADF technology combines high efficiency (3 times better than the state-of-the-art fluorescence technology) together with long lifetime.

OLED displaysincorporating blue TADF materials will reduce power consumption up to a factor of 2.

CYNORA has developed deep blue material reaching an EQE of 16.3% (at 100 cd/m2) compared to 3% reached in October 2015, a factor 5 improvement in six months. In parallel, the company is using sky blue material to improve the device lifetime.

A significant increase in the lifetime to more than 400 h (LT50, 500 cd/m2) has recently been achieved from a level of a few minutes in last October.

“We have yet to reach the performances requested by the OLED display industry” says Thomas Baumann, CYNORA’s CSO, “but our rapid progress during the last 6 months proves our capability to reach the performance levels we have defined together with our key customers to support their technical roadmap. We will use the coming months to combine both efficiency and lifetime in a single deep blue material.”

CYNORA owns a broad IP portfolio on TADF with over 100 patent families and is aiming for over 600 patents.
