IP Portfolio holder IPValue Management acquired over 1,200 patents and applications from Mitsubishi Electric's display business unit. The IP, a result of over two decades of R&D, encompasses a wide range of LCD, OLED and other technologies.
The patents will now be owned by IPValue's subsidiary, Trivale Technologies. The financial terms of this agreement were not disclosed.
Researchers from the University of Michigan developed a new electrode design for OLED devices, that can increase light output by up to 20% compared to current electrodes. The new electrode is compatible with current production processes.
The new design helps to minimize the waveguiding effect, which traps around 80% of the light produced by the OLED emitters. The researchers used a modal elimination approach, which involves optimizing the organic stack and the replacing the ITO anode with a thin film of silver deposited on a layer of copper. This kind of approach can be applied to other light emitting structures such as inorganic LEDs, perovskite LEDs, quantum dots and more.
Universal Display and LG Display announced that the companies have extended their long-term agreements. LGD and UDC signed new OLED Technology License and Material Purchase Agreements. The new extended agreements run for five years.
UDC and LG did not disclose any further details or any financial terms. The two companies signed the original agreement in 2015.
Earlier this month we reported that the US district court in Texas decreed that Samsung Display and Samsung Electronics are to pay $62.7 million in damages as the companies wilfully infringed upon two of Solas OLED fundamental OLED patents (USPTO #7,446,338 and #9,256,311).
Samsung proceeded to file a patent office challenge against the #311 patent, and apparantly Samsung won the challenge. The patent describes a flexible touch sensor that is wrapped around the edge of the display - and Samsung argued that as a flexible touch sensor is already known, this patent is "obvious". It appears as if Samsung will not have to pay the $35.4 million in damages for this patent.
Ireland-based OLED IP company Solas OLED announced that a jury in the US district court in Texas has found Samsung Display and Samsung Electronics liable to Solas for wilfully infringing two fundamental OLED patents (USPTO #7,446,338 and #9,256,311). The jury awarded solas with $62.7 million in damages.
Solas says that these patents are required for AMOLED to function - these patents were used in the OLED displays used in Samsung's Galaxy S and Galaxy Note smartphones.
Ireland-based OLED IP company Solas OLED announced that it has filed a new patent infringement lawsuit in Germany against Samsung Electronics.
Solas did not disclose the exact patents related to this lawsuit, but the company says its patent portfolio "covers all critical areas of OLED structures, display design and architecture, and driver circuitry", and that Samsung is using the company's inventions in various devices, such as smartphones, watches and tablets.
Ireland-based OLED IP company Solas OLED announced that LG Display settled its OLED TV patent dispute with the company, and has agreed to pay a license for its patents. This resolves a number of patent infringement actions (in the US, China and Germany) brought by Solas against LG Display and a certain number of its customers, including Sony Corporation.
Towards the end of 2020 Solas filed a complaint to the US International Trade Commission against Samsung Electronics and BOE, saying that the two companies infringe upon some of its AMOLED patents.
TADF materials developer Kyulux announced that it has finalized its Series-B-prime funding round, raising $34.3 million USD from several VCs and companies. Kyulux will be able to now accelerate its product development and drive for adoption of its materials in smartphone OLED displays.
Kyulux also announced plans to establish a mass production system for its materials, in cooperation with chemical companies.
According to a new report from Korea, two SDC researchers were convicted of handing over OLED technology to other companies, and are being sent to prison for two years. Representative and directors of the company that bought the technology was also sent to prison and the company was fined.
The technology in question relates to Optical Adhesive Materials used in OLED production processes. The arrest of these employees was reported in August 2020.
Towards the end of 2020, Ireland-based OLED IP company Solas OLED filed a complaint to the US International Trade Commission against Samsung Electronics and BOE, saying that the two companies infringe upon some of its AMOLED patents.
The US ITC apparently decided to launch a section 337 investigation aginst both BOE and Samsung. Solas OLED requested that the ITC to issue a limited exclusion order and cease orders.
