LG Display announced today that it will invest in a new OLED light panel manufacturing facility.

The planned facility will be the first 5th generation (1000 x 1200mm) OLED light panel manufacturing plant in the world. It is to be located in the South Korean city of Gumi, where it will produce a range of OLED light panels. The initial input capacity at the plant will be 15,000 glass substrates per month.

The monthly input capacity could be gradually ramped up depending on the market situation. LG Display expects the increased production with the new facility to give the company economies-of-scale.

This will help the company obtain significant price competitiveness. In addition, the accumulated OLED display technical know-how will allow LG Display to considerably enhance OLED light product quality.

The 5th generation facility will give the company panel size flexibility. With the larger glass substrate, LG Display will be able to produce a wide range of different size light panels, including giant ones. Further, this ability to make giant panels will better enable the company to penetrate the general lighting market.

The investment decision follows the acquisition by LG Display of the OLED light business of its sister company, LG Chem in December, 2015. The plan for the new facility is in keeping with LG Display’s vision of bringing the exciting new OLED technology to customers around the world in the broadest array of applications.

The company will firstly focus on task lighting and decorative lighting in high-end retail stores and in luxury hospitality; and expand to the general lighting market going forward.

Also, the company will focus on automotive and convergence applications such as OLED light panels merged with furniture, architectural materials, electronic devices and more.

Mr. Young Kwon Song, Senior Vice President and Head of Strategy & Marketing Group at LG Display, said, “Our OLED light business will further strengthen LG Display’s commitment to nurture OLED as the future growth engine. Based on LG Display’s strong track-record and know-how in OLED display business, we will create synergy with the OLED light business and maintain our strong position in the overall OLED industry going forward.”

LG’s OLED light experience began in 2000 with R&D into OLED materials at the Group’s chemicals affiliate, LG Chem, with production of OLED light panels beginning in 2012.

The acquisition last year of the OLED light panel manufacturing business by LG Display has been creating synergies with its production infrastructure and technology in OLED displays.

It allows the company to save costs through integrated purchasing and shared investments, increase productivity by drawing on the accumulated knowledge of the display business, and help improve production infrastructure and use of technology patents.

OLED light is made up of layers of organic materials which is self-illuminating and consumes less power and also emits lower heat than conventional lighting.

It is environmentally friendly and is closest to natural light. Due to its ability to be thin and flexible, it is suitable for different applications and venues and could create new markets for lighting.

According to UBI Research, a market research firm, the OLED light market is expected to grow rapidly from US$ 135 million in 2016 to US$ 1.6 billion in 2020.

OLED and Graphene Together Achieves Innovative Technology

By Choong Hoon Yi

 

Korean research team is expected to greatly improve display’s transmittance and picture quality through fusing graphene technology, focus of much attention as the new material to OLED technology.

 

On December 15, ETRI (Electronics and Telecommunications Research Institute) replaced the thin metal electrode that was used as transparent electrode on top of the OLED substrate with graphene transparent electrode, and succeeded in developing original technology that is conductive and transparent.

 

This research results were presented in Scientific Reports, a journal from the publishers of Nature on December 2.

 

The metal electrode used in OLED until now has been mostly silver material, but due to the reflection of internal light, the viewing angle changed depending on the angle. The external light also affected picture quality due to reflection.

 

In order to solve this problem, ETRI research team focused on graphene that mostly does not reflect internal/external light. By replacing the material, the team reported that the transmittance increased by approximately 40% and reflectance improved by approximately 60%.

 

OLED was successfully lighted by attaching graphene transparent electrode to the organic layer on top of the film form (23 x 23 mm, 30 ㎛ thickness) of substrate. The research team believes this will be able to contribute much when applied to transparent OLED display and white OLED-based large area OLED display in future.

 

Particularly, unlike the existing vacuum process OLED production method, this technology can be employed via lamination where film is attached to the organic layer and graphene. Therefore, OLED can be produced through simpler process. It is expected that this can be evolved into production technology using roll to roll process.

 

Additionally, ETRI, together with Hanwha Techwin, is working on applying graphene transparent electrode to OLED’s lower electrode through collaboration of high quality graphene thin film electrode materials. The related technology development results were published online by The IEEE (Institute of Electrical and Electronics Engineers) of Selected Topics in Quantum Electronics.

 

ETRI’s Dr. Jeong-Ik Lee (soft I/O interface research section) anticipated that “this technology will be able to play a role in widening the gap with latecomer countries in OLED industry where challenging latecomers are strong”.

 

This research was carried out through Korea’s Ministry of Science, ICT and Future Planning and Institute for Information & Communications Technology Promotion (IITP)’s “Energy reducing environment adapting I/O platform technology development for future advertisement service” project and Ministry of Trade, Industry and Energy and Korea Evaluation Institute of Industrial Technology’s “Substrate size 5.5 generation or larger graphene film and OLED device/panel foundation and application technology development for graphene materials OLED transparent electrode and thin film encapsulation application”.

 

ETRI is planning to additionally develop sheet tension reducing technology by manufacturing metal in thin, grid forms and enlargement technology to produce mobile display size within 2016.

 

Through this technology, the research team produced 6 international patent applications and 6 papers. ETRI is intending to transfer the technology to graphene film and display panel companies among others. Commercialization is estimated to begin after 3 years.

In this exhibition, ETRI presented OLED lighting that used graphene as the electrode. ETRI’s Dr. Jeong-Ik Lee explained that recently interest in graphene electrode is increasing to replace ITO electrode and to apply graphene electrode, optical, electrical, and process issues have to be considered. When graphene is used as OLED electrode instead of ITO, thickness and refractive index change optically and electrically energy levels change, and these have to be considered when designing. He also emphasized that in terms of process, it has to be designed keeping in mind of before and after process of electrode procedure. Dr. Lee revealed that at present optical and electrical issues are solved while the process issues are in research stage, and they are planning to present the results of this research within this year.

 

Graphene, with its high resistivity, is known as next generation electrode material favorable to flexible and foldable. Dr. Lee pointed out that graphene has wider viewing angle than ITO when used as transparent electrode is another important advantage, and particularly as white light source’s spectrum cannot change according to the viewing angle, graphene is suitable for application.

 

Graphene is a key material with a wide arrange of applications, it is being developed in diverse areas such as OLED encapsulation as well as in electrode sector. The Ministry of Science, ICT and Future Planning of Korea estimated that domestic graphene market will record 19 billion KRW until 2025. Korea Evaluation Institute of Industrial Technology, the organization in charge of this national project, gave their target as developing 9 top technology through graphene and achieve 17 billion KRW sales. Regarding this, Dr. Lee emphasized compared to other countries, Korean investment in graphene is relatively low and that now is the time for the Korean corporations and government agencies to pay more attention higher value-added businesses.
