Conference Introduction

The 2024 Chinese Flexible and Printed Electronics Symposium (Flex China 2024) is to be held in Suzhou on 23-25 October 2024


Printed electronics uses printing technologies to make flexible and large area electronic and optoelectronic devices and systems. It is a green manufacturing process and has become a new paradigm in electronic manufacturing. Printing is already adopted in OLED/QLED display panels production, printing is becoming one of the mainstream technologies for making sensors for IoT. Printing is changing the way the printed circuit board (PCB) are made. Smart packaging based on printed electronics will have great impact on traditional printing and packaging industries. Printed electronics on variety of flexible substrate materials such as plastics, papers, textiles or stretchable materials will enable wide range of form factors for electronic products, therefore, open up vast possibilities of new applications.


China started its own printed electronics development in 2010 and held the first symposium that year. Since then, the symposium has been held for 14 consecutive years, including 2 international conferences (ICFPE 2014 and 2018) hosted in China. These symposiums have stimulated the interests of Chinese researchers and industrialists to get involved in the field. From 2017, the Symposium became one of the SEMI’s global FlexTech meeting series and branded as “Flex China”. SEMI is the international organization for semiconductor industries. By forming the alliance with SEMI, the symposium became international. It also reflected the global trend of combining integrated circuit (IC) with printed electronics to enable practical applications of flexible electronics.


The 2024 Chinese Flexible and Printed Electronics Symposium (Flex China 2024) will again be held in Suzhou on 23-24 October. Built on its previous success, the Flex China 2024 will continue to serve as a platform for the exchange of information and progress in the field of flexible & printed electronics.


The Flex China 2024 is under the umbrella of the 2024 China Nano Conference & Expo (CHInano), with several other events in parallel to be held in the same time and at the same venue.

Abstract:

An ultra-thin metal based flexible transparent conductor was developed to offer advantages such as flexibility, low temperature processing, high electrical conductance and optical transmittance that can be tailored for different applications. It has already been applied to several types of optoelectronic devices, such as touch panels, electrochromic window, OLED and PVs. When used as transparent anode for OLED, it addresses a long-standing challenge of light trapping in OLED, which limits the device outcoupling efficiencies. In contrast to the commonly used ITO that has the highest refractive index within the OLED layer stack, thin-Ag based transparent anode can eliminate the waveguide mode, thereby liberating the light that otherwise trapped within the OLED layers. Its high conductance makes it ideal for large screen multi-touch applications. The transparent metal electrode can be advantageously applied to OPV by virtue of its low sheet resistance and adjustable reflectivity; and is also shown as a promising transparent conductor for perovskite PVs, promising cost advantages. It is also compatible with moisture barrier coating on plastic substrate, together the two can account for more than half of the material cost for future flexible perovskite PVs.

Abstract:

Based on the fundamental scientific issues of nanomaterial preparation and functional inkjet patterning, a systematic Nano Green Printing technology has been developed. The precise control of the conversion from translational kinetic energy to rotational kinetic energy before and after droplet collision has been achieved using patterned wettability surfaces. This process breaks through the scope of classical Newton’s collision law and realizes a change in the motion mode of droplets before and after collision, providing new ideas for the preparation and precise control of high-precision patterns. Starting from the manipulation of droplets for three-dimensional shaping, spontaneous contraction of droplets in three-dimensional space has been achieved by using templates, enabling rapid assembly and shaping of three-dimensional micro/nano structures using multiple materials. Furthermore, the evolution of foam has been controlled using micro-templates, overcoming the long-standing challenge of patterned control of bubbles, and realizing the anti-Oswald ripening and patterning of bubbles. This has been used as a printing template for the assembly of multiple functional materials. In particular, by utilizing the advantages of droplet manipulation in nanoscale green printing, we discover the critical conditions for the scattering-diffraction transition of nano-photonic structures, an optical metamaterial detection chip has been developed for ultra-sensitive and rapid detection of novel coronavirus, influenza virus, and tumor markers. This opens up new ideas for the printing fabrication of functional devices and micro/nano chips, and establishes the theoretical and technical system of nanoscale green printing technology.


Speakers of 2024 Conference
Yulong Gao
(Chairman of Board,Shine Optoelectronics (Kunshan) Co., Ltd.)
Flexible Electronic Skin for Robotics and Interactive Systems (Online)

Biography:Dr. Yulong Gao, after earning his bachelors, masters and doctoral degrees from Harbin Institute of Technology, worked as Postdoctoral Fellow of Suzhou Institute of Nano-Tech and Nano-Bionics (SINANO), Chinese Academy of Sciences. Hes Inventor of the embedded nanoprinting technology, Founder & Chairman of Shine Optoelectronics (Kunshan) Co., Ltd., member of National Key Talent Project and winner of China Patent Gold Award. He owns 412 patents, including 286 authorized patents; he has received 144 invention authorizations, including 61 in China, 22 in the US, 23 in Taiwan, 21 in Korea and 10 in Japan. The invention patent "Graphic Flexible Transparent Conductive Films and its Fabrication Method" (Patent No. 201110058431.X) won the 16th China Patent Gold Award in November 2014, which is the first national patent gold award won by Jiangxi Province.

Abstract: The global electronics industry has embarked on the study of using additive manufacturing to replace photolithography in circuit manufacturing since the 1990s, such as screen printing, intaglio printing and inkjet printing. In 2010, the team of Suzhou NanoGrid Technology Co., Ltd. lead by Dr. Yulong Gao invented the new technology of preparing conductive circuits with embedded printing that achieved a printing resolution of 1.3 microns, based on which the manufacturing of flexible and transparent conductive films met large-scale application in the touchscreen industry. However, due to its dependency on silver ink, this technology has a setback that its resistivity after sintering is generally 6*10-6 Ohm Meters, which is two orders of magnitude lower than that of pure copper (1.8*10-8 Ohm Meters), while its cost is much higher than copper. In view that annual output of todays printed circuit board (PCB) industry amounts to 700 billion RMB that has a high reliance on copper corrosion technology, green manufacturing of printed circuit boards at a low cost can only be achieved with a breakthrough in the additive manufacturing of pure copper. In 2015, Dr. Yulong Gao founded Shine Optoelectronics, where he and his R&D team finally realized the technological breakthrough in and commercialization of the embedded additive manufacturing of copper circuits through eight years of efforts and achieved a minimum copper circuit width of 500 nanometers. Today, the circuit boards made using this technology have been commercialized in the field of TV, and are heading toward more fields such as display, automotive and IC chip carrier.
