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.

[2nd OLED KOREA Conference] Visionox Reveals Core Keyword for Flexible OLED Surge

On February 24, Dr. Xiuqi Huang, Visionox’s general manager, gave a keynote speech at the 2nd OLED KOREA Conference (Feb 24-25). With the presentation title of Development of AMOLED Display: From Rigid to Flexible, Dr. Huang discussed how the flexible display was introduced and its future.

 

Flexible display is expected to solve CRT’s heavy weight, and FPD’s design limitation. Key issues include thin film formation process, structure that can withstand bending, and materials with high tensile strength. Dr. Huang emphasized that OLED is a display that can solve all 3 issues.

 

In order for flexible OLED to make the leap, Dr. Huang announced that 7 technological developments need to be carried out: encapsulation, TFT backplane, array design, flexible technology, flexible substrate, stress management, and module integration.

 

Visionox first developed flexible OLED in 2001, and revealed 5.2 inch flexible AMOLED of rollable type with 3 mm curvature radius and 20 um thickness in July 2015. They are aiming for mass production within 2 years.

 

Regarding OLED mass production, Dr. Huang revealed that the Gen 5.5 AMOLED mass production line phase1 4K will be increased to 15K until 2016, and Gen 6 AMOLED mass production line is expected to be in operation in 30K volume in 2017.

 

[MWC 2016] Tianma Reveals Their First Flexible AMOLED Panel

In MWC 2016 (Feb 27 – Mar 2), Tianma, a Chinese AMOLED panel company, revealed 5.46 inch flexible AMOLED panel for the first time. This panel has HD resolution (720 x 1280) with the curvature radius of 20 mm. Additionally, Tinama also exhibited 5.5 inch and 5 inch FHD AMOLED panel, and 5 inch HD AMOLED panel.

 

Tianma added that the 5 inch HD AMOLED panel is expected to be actively mass produced in the first half of this year and it is being produced in smaller quantity and that additional investment will soon be carried out for Gen5.5.

 

Tianma is currently carrying out small volume of mass production using Ulvac Gen4.5 manufacturing equipment. Although Tianma continued presenting their products in display related exhibitions, it is their first time in a set exhibition such as MWC. This activity is analyzed to be a part of Tianma’s effort to further their client base before active AMOLED panel mass production.

Samsung and LG’s Shared Vision for OLED

On the first day of OLEDs World Summit (October 27-29) held in Berkeley, USA, Samsung Display and LG Display gave their talks back to back. Samsung Display’s Vice President Chang Hoon Lee and LG Display’s Joo Soo Lim discussed their thoughts on OLED under the titles of ‘The Future of OLEDs’ and ‘A Future Game Changer’ respectively.

Samsung Display’s Lee, who gave his presentation first, reiterated Samsung Display’s leadership position in the mobile market and how Samsung Electronics’ recent mobile display reflects this. Comparing RGB pixel structure and their own diamond pixel structure, Lee drew comparison between human eyes and diamond pixels; due to cell distribution in eyes, humans are more sensitive to green colors and that diamond pixels reflect this by having twice as many green subpixels as blue and red ones. The diamond pixels also maximize the sub-pixel packing and increases the PPI.

Regarding the advantages of OLED display, Lee gave 2 examples using Samsung Electronics’ latest smartphone models. Utilizing the fact that selective control of each pixel is possible in AMOLED displays, Samsung provided Vision Aid to help people with color blindness. OLED’s ability to achieve total black is used in Super Dimming function where screen brightness can be reduced to 2nits to be used in the dark environment.

LG Display’s Lim revealed that an adult in the US spends 9 hours 40 minutes a day on average looking at one form of display or another. Highlighting the need and importance of quality display, Lim also discussed advantages of OLED display over LCD such as total black, 3D effects, and color gamut.

As the future OLED display, Both Lee and Lim placed slightly more emphasis on flexible (plastic) OLED than transparent or mirror display. Samsung Display discussed requirements necessary for a successful flexible display in more depth touching on the need for suitable cover window, flexible touch (sensor), flexible encapsulation, and flexible backplane. On the other hand, LG Display discussed flexible display’s design freedom and its influences on the wearable, mobile, and automotive markets. Lim also placed much importance on how flexible OLED can be used in virtual reality display market. The 2 speakers ended their talks affirming the need for new display market and innovation through OLED technology and new applications.

The presentations given by the 2 apparent leaders in the OLED display industry were remarkably similar with both speakers underlining major points of OLED in broad strokes. The need for solutions for future OLED, whether it be flexible, transparent, or mirror display, through innovation and technological advances is an absolute truth if not maybe too obvious. There also may be some comfort to be had in the shared vision within the OLED community. However, it is also a fact that numerous attendees of the conference commented on the similarities of the 2 presentations and the lack of any surprises.

Attention Focused on Silver Nanowire as Key Material for Display

At IPEC 2015 (International Printed Electronic Conference), held on September 1, Professor Sang-Ho Kim of Kongju National University announced that silver nanowire technology is in initial stages of commercialization and will become display market’s key material.

 

Kim reported that when the bending radius of flexible display is reduced, 2 key issues occur with silver nanowire used as TSP (touch screen panel) material. First, the wiring that are crossed when bending is loosened as can be seen in figure 1. Due to this effect the bending stability decreases.

Silver nanowire has benefit of being more flexible and less resistant compared to transparent electrode material, ITO. As such, it was spotlighted as TSP material most suitable for flexible OLED. Nonetheless, silver nanowire has been considered to fall behind ITO in panel mass production unit cost in display market.

 

However, haze effect which happens when sunlight is reflected off the silver nanowire TSP has been solved recently, and new touch technology that requires improved TSP functions, such as post-touch technology, has been developed. Accordingly, products that use silver nanowire are increasing despite the unit cost difference.

 

Kim reported that as TSP sheet resistance can be reduced through undercoating and welding technology and greatly increase bending stability, it is estimated that silver nanowire’s marketability will grow for flexible display.
