/0 コメント/カテゴリ: , /作成者:

Phonearena, a dedicated website providing smartphone related information, reported that Samsung will start mass production of 5.9-inch UHD Super AMOLED above 700ppi in August next year.

The source of this news is not clear but at the last Analyst Days event, Samsung said that it is expected to produce UHD 2160×3840 AMOLED display in 2015. In addition, they also hinted the UHD display for a smartphone device through the roadmap presented at the workshop held last January using the word ‘diamond pixel’. This is closer to the PenTile method than the RGB stripe method.

They also mentioned 600ppi in the interview with LG Display in May of last year. And even added that the 700ppi panel for a smartphone device is eminent and Samsung’s effort for high picture quality is not surprising. It was reported that besides Samsung and LG, Sharp is recently working on 4K display for a mobile device which comes in as 5.5-6 inches.

It was measured that the UHD picture quality will be 746ppi for 5.9-inch panel. If it is intended for August of next year, the announcement is expected to be at IFA 2015, equipped in the Note 5.

Korean researchers have developed the highly efficient florescent organic light-emitting device which enables to enhance the efficiency more than three times and is receiving much attention as the next generation display.

This research by the Prof. Jun Yeob Lee, the Ph.D. candidate/researcher Yong Joo Cho (the 1st author) and the Prof. Kyoung Soo Yook from the Department of Polymer Science and Engineering at Dankook University was supported by the Mid-career Researcher Program funded by the Ministry of Science, ICT and Future Planning and the National Research Foundation of Korea as well as the General Researcher Program funded by the Minister of Education and the National Research Foundation of Korea, and the research results were published on the Advanced Materials which is the international journal covering  materials science on the 15th October. (Paper Title: High Efficiency in a Solution-Processed Thermally Activated Delayed-Fluorescence Device Using a Delayed-Fluorescence Emitting Material with Improved Solubility)

Using the solution processing, it is expected to ease and simplify the process of producing the organic light-emitting device as the large area compared to the existing vacuum deposition plating.

However the problem is that when a device is produced through the solution processing using the existing fluorescent emitting material, the efficiency (external quantum efficiency) is only 5%. This is much less than the 20% which is the efficiency when produced by the vacuum deposition plating process.

The research team developed the high efficiency fluorescent organic light-emitting device, improved three times more than the previous fluorescent device for the solution processing. Compared to the existing structure, a solubility was increased by introducing the alkyl group as a substituent. Furthermore, the Donor-Acceptor Structure was employed to realize high efficiency by inducing delayed fluorescence phenomenon.

It is anticipated to advance the commercialization of a large scale organic light-emitting device for the enlargement of a future display.

The decrease of efficiency issue was resolved by making the surface film coating of a device smooth through the development of a new fluorescent light-emitting material which is soluble in organic solvents.

And introducing the strong Donor – Acceptor structure, it was possible to improve the efficiency as drawing delayed fluorescence phenomenon. The Donor – Acceptor structure refers to a monomer composed of an entity that donates electrons to another compound and that accepts electrons transferred from another compound.

Professor Lee revealed that “The following research will be continued to commercialize the solution processed fluorescent organic light-emitting device by developing a new material to improve not only the efficiency but also the lifespan of a device and a device structure appropriate for a solution processing.”

The DVCE (Display Valley Conference & Exhibition), supported by Samsung Display is held in every November in Asan, Chungcheongnam-do as one of the major events in the region which has established its position as a mecca of display industry. It is an international conference created by the active support from Samsung Display for the purpose of local development and industrial development of display business and it is the 10th year of DVCE in 2014.

In the first day of DVCE on the 11th, Hak-sun Kim, the vice president of Samsung Display gave a key note speech titled “Display Beyond Imagination”, suggesting the future directions for display through humanistic considerations.

Given that most of display related conferences or seminars are primarily of hardware or technology associated contents, this was the first occasion that the directions for the future display was proposed. Comparing the display with the history of art, Kim defined a new technology market to converge analog and digital. He mentioned the necessity to produce creative display by employing new functions in display as famous art masters have created innovative artworks by developing various techniques.

In particular, he has emphasized that it is critical to produce a human-friendly product as a human interface through fundamental understanding and reflection on the light and human eyes when developing a display. Kim proposed a vision for the future of the convergence product equipped with varied functions like lighting and eye, bio sensor, haptic sensor, etc. through the techniques employed by the artists like lighting and perspective, trompe I’oeil, texture, etc.

Kim expressed sincere regret for the decrease of display industry in Korea where new products are no longer produced, claiming the need for engineers who develop displays to converge and combine by means of humanistic consideration in order to promote display industry.

Declining Japan’s Display Industry

/0 コメント/カテゴリ: , /作成者:

The downtrend of Japanese display industry became obvious once again at the Display Innovation. Originally titled as the FPD International, the Display innovation 2014 was renewed with a different name to evoke a fresh wind in the display industry of Japan, only to find that it had failed to draw attention from the interested parties of the FPD industry.

At the FPD International 2013 held last year, about 200 FPD related companies participated whereas only 80 companies exhibited at the Display Innovation of this year, and the scale of the conference was also reduced drastically as implementing the event not in the existing convention center but in a section of the exhibition hall.

It was evident that the Japanese display industry is in the downturn as only Japan Display was joined as a panel company exclusive of the major Japanese panel makers like Sony, Sharp, Toshiba, Panasonic, etc.

However, it presented that the Japanese Display Industry is still alive as Japan Display reveals flexible AMOLED and technical skills to improve response rate of the LCD and color reproduction and real black, etc. of the LCD. And SEL shows AMOLED related new technologies.
