Development of Silver Fiber Flexible Transparent Electrodes

Overcoming Silver Nanowires’ Limitations and Enabling Flexible OLED Introduction

While OLEDs are emerging as a new display technology, there are many reasons why nanowires used for OLED production have limitations. Accordingly, Korean researchers have developed a technology to overcome this shortcoming.
The National Research Foundation of Korea (Chairman Cho Mu-je) announced that professor Ju Byeong-kwon (Korea University) and Professor Park Yeong-wook (Sun Moon University) of developed flexible transparent electrodes for displays with remarkably improved luminous efficiency by producing silver fibers 100 times longer than silver nanowires.
Silver nanowires feature silver wire network structures with sections whose diameters are in centimeters. While current ITOs are not flexible, silver nanowires are flexible and have excellent conductivity and transparency as ITO electrodes. Due to this fact, silver nanowire is gaining popularity as a promising material for flexible transparent electrodes for next-generation flexible displays and lighting devices.
However, the length of nanowires is limited to several dozen micrometers (µm), which limits improvements in conductivity and transparency in utilizing silver nanowires in OLED displays and surface roughness increase due to line joining, giving rise to a limitation of being electrically unstable.
Using an electrospinning process, the team developed silver fiber electrodes with a length of several centimeters (centimeters) in length and no junctions, ensuring conductivity, transparency and electrical stability.

The electrospinning process is a process by which fibers produced by injecting a polymer solution into an electric field. As the process is simple and can produce a large area of fibers, this process can thus be applied to large OLEDs for display and illumination.
The research team maximized conductivity and transparency by controlling the thickness and density of silver fibers, resulting in 19% higher energy conversion efficiency than OLEDs using ITOs.
“This research is the first case of developing a silver electrode that overcomes the limitations of silver nanowires and introducing them to OLED,” explained Professor Ju Byeong-kwon. “It is expected that the silver fiber will contribute to securing the core technologies in wearable display and lighting market.”
“Silver fiber flexible transparent electrodes can be applied to various optical electronic devices such as LEDs, solar cells, touch screens, and optical sensors in addition to OLEDs. Silver fibers with excellent conductivity and transparency have great potential in various application fields, “Silver fiber electrodes can be produced to have wide areas and have low resistance. Therefore, when a silver electrode is applied to OLED lighting, which is being researched as next-generation lighting, we can solve problems such as high driving voltage and non-luminescence.

The World’s First developer of MOCVD IGZO TFT process and equipment ; JUSUNG Engineering

April 1, 2013 by 1,802 Comments

사진As a leader in semiconductor, display and solar cell manufacturing technologies in the global market, JUSUNG Engineering is asserting its ever-higher global presence. Itspioneering deposition technology enables flat panel display makers to dramatically enhance high-definition resolution in next-generation displays.

The new product utilizes a metal organic chemical vapor deposition (MOCVD) technology to apply the critical transparent semiconductor oxide material for use on flat panels. This new material, IGZO – Indium, Gallium, Zinc, Oxygen, replaces the traditional amorphous silicon based active layer. IGZO has an electron mobility 40 times greater than traditional materials such that a display’s reaction speed can be more swiftly controlled. In doing so, panel makers will be able to offer screen resolutions higher than the current Full High Definition. JUSUNG is the only company in the World that offers this MOCVD IGZO capability for 8th-Generation-sized panels.

MOCVD offers significant benefits over conventional deposition methods. Specifically, it allows panel makers to fine tune the composition of the IGZO material to customize it for their application. This is a significant step in the application of the new material because previous conventional deposition methods such as sputtering limit the composition to fixed ratios. By improving upon these shortcomings, JUSUNG expects this new MOCVD technology to gain market acceptance as panel makers seek to expand their product offerings.

JUSUNG’s new MOCVD IGZO is compatible with next-generation LCD TVs, OLED TVs, and mobile displays. As such, the company will focus on enhancing this technology to secure a greater share of the flat panel deposition market.

A JUSUNG Engineering representative explained, “The display companies of the world have set out to transform high-speed display technology through utilizing IGZO materials.” He added, “By being the first to market with this enabling technology, JUSUNG Engineering will also accelerate its increasing market influence as a leading global capital equipment manufacturer.”

Since itsestablishment in 1995, JUSUNG Engineering has been a leading provider of manufacturing technologies for the global marketplace. Based in Korea with a network of worldwide offices, it offers innovative and differentiated technologies for the semiconductor, flat panel display, and solar markets. It has also entered the lighting market through leveraging its core technologies and applying them for LED and OLED lighting. JUSUNG’s innovations are currently employed in many of the world’s leading technology manufacturing companies. As such, JUSUNG is securing its position as an industry leader for enabling, next-generation technologies.
