Eindhoven's Technical University (TU/e) announced a new project called SEQUOIA that aims to develop a strategy for the suppression of exciton quenching in OLED devices.

Exciton quenching, caused due to unwanted interactions among excitons and between excitons and charges, causes the efficiency of OLEDs to drop as brightness increases. The researchers hope to develop new materials and new OLED design to suppress (or hopefully eliminate entirely) this problem.

OLED lighting developer Inuru announced that it is now capable to print OLED panels in any shape, on demand.

Inuru has setup a pilot line in Berlin Adlershof. The company says its new panels offers very small size, as required, and excellent homogeneity. The company can pair it with thin printed batteries to power the lighting panels.

China-based Semiconductor Integrated Display Technology, or SidTek, is an OLED microdisplay developer established in 2016. The company has recently started to produce OLED microdisplays on 8-inch silicon wafers, at its first production line located in the Chenhongda industrial park, in Wuhu, Anhui province, China.

Sidtek currently produces three display types in production

• 0.39" 1024x768 full-color
• 0.61" 800x600 or 1280x1024 full-color and monochrome
• 0.97" 1400x1050, monochrome

Omdia says that demand for AMOLED displays increased 52% from 2020, to reach 14.2 million square meters. The main drivers of this growth were higher OLED TV and smartphones sales.

Omdia expects the OLED market to continue its strong growth, even though growth will be slower in the future. The demand for AMOLED display area will grow by CAGR of 11.6% from 2021 to 2028, to reach 30.7 million square meters.

At the end of this month Toray Research Center (TRC) will host an online webinar focused on OLED technologies. TRC, who supplies technical analysis and support for R&D and manufacturing, invites you to attend the online lectures at no cost, to learn more about OLED technologies and analysis of OLED devices.

The webinars will include recorded presentations, which will be available online from February 22 to March 08. You can register for the webinars here.

Researchers from National Taiwan University, led by Prof. Chung-Chih Wu, have developed a 3D pixel configuration for OLED devices, which can improve the light extraction. The new design can improve the external quantum efficiency of a top-emitting OLED device by up to 30%.

The new design uses a 3D reflective pixel structure filled with a patterned high-index material. The researchers created several pixels with difference sizes, and found that the smaller the pixel, the higher the efficiency boost.
