This report consists of a detailed analysis of 94 patents filed by Samsung Display in relation to QNED, which were released by the second week of October 2020. In the first half of last year, QNED was analyzed as 41 patents, and there was a difference of about 6 months in the additional patents, but surprisingly technological progress was confirmed.
The backplane of QNED is 7T2C TFT, and it was found that the oscillator for aligning the nano-rod LED and the transistor for repair are arranged together. The QNED circuit was configured similar to the TFT structure used in OLED for mobile devices. Since QNED is also a current driven device, it seems that precise control is required. Large OLED uses 3T1C structure.
Among the additionally confirmed contents, the most remarkable one is the built-in alignment transistor (oscillator). Nano-rod LEDs are dropped onto the panel in ink state and aligned by dielectrophoretic force by the electric field applied to the panel. At this time, the number of nano-rod LEDs and the pixel yield are determined according to the alignment waveform. Oscillator technology has never been used in displays.
While the OLED industry, which had been stagnated by COVID-19, is reviving, various technologies such as LTPO TFT and micro lightening pattern (MLP) were newly applied to OLED products in 2020.
In the “2020 OLED Component and Material Report” published this time, we analyzed new technologies and supply chains of OLED component materials for foldable devices, mobile devices, and TVs of each panel maker, and predicted future applicable technologies as a roadmap. In addition, we predicted the MP capacity and shipments of each panel maker by 2025, and predicted the market for key parts and materials such as substrate and TFT, encapsulation, touch sensor, adhesive, cover window, and module.
It will be an important guideline in setting up a business strategy to respond to the OLED-related technology and material market in the future.
As the ‘OLED emitting material patent analysis report’ is published monthly in cooperation with UBI Research and Lordin Co., Ltd. (CEO Hyoung Yun Oh, www.lordin.net), a company specializing in OLED emitting materials, a patent analysis report that classified and analyzed the latest patents related to OLED emitting materials and excel data are provided together.
In addition, it is expected to be of great help to people in related industries because it deals with the issue of patent reviews and expired patent data.
The purpose and use of the “2H 2020 OLED Display Report” is to use it as data for planning for 2021, which must be established by each company. Therefore, this report organized a table of contents by application, analyzed the situation by industry, and looked at the market.
In particular, 2021 is the year when the new coronavirus situation is still in progress, and it is necessary to see the market from a different perspective.
Exhibitions and conferences were held only in the first half of 2020, but this report summarized the situation and exhibition trends of set manufacturers and panel manufacturers. It also analyzed the results of the first half and recorded the market outlook for the second half and the first half of next year.
The “Latest OLED Technology Trend Report” analyzed the research presented by display companies, research institutes, and universities in SID, IMID, IDW from 2016 to 2020, and carefully selected and organized only the technology used in OLED manufacturing and the technology deemed applicable in the future.
It was compiled by Urabe (former Sony OLED development team leader/development director), a senior analyst at UBI Research.
The report will be a guideline that shows OLED developers the goals and directions of development by technology.
The AMOLED manufacturing process report analyzes the structure and manufacturing process by dividing AMOLED into small and medium-sized and large-area, and also schematics the inspection process of small and medium-sized AMOLED, so each company can understand the overall structure and core processes of AMOLED.
The LTPO TFT process and QD-OLED process were added to the AMOLED process report ver.3 published this time.
This report is a must-read report for not only panel makers but also equipment and parts and materials makers to understand the AMOLED manufacturing process.
UBI Research published and published a trend report of China related to the OLED industry at the end of the first half of 2020.
The purpose of the publication of this report is to separate the trend of China’s ever-growing size and technological advances, and to organize them through detailed analysis.
This report includes product launch trends of OLED-related Chinese set makers during 2019 ~ the first half of 2020, business status and investment status by major panel manufacturers, supply chain for major products, various performance analysis and forecasts, and includes the trend of recently announced exhibition products.
