South Korea Printed Electronics Industry Opens New Opportunities

South Korea has emerged as a global leader in the rapidly growing South Korea Printed Electronics industry. The country is home to many pioneering companies commercializing printing technologies for applications like flexible displays, solar panels, sensors and more. Korean companies are leveraging the country's advanced electronics manufacturing base and culture of innovation to drive new applications and business models in this transformational field.

Printing processes allow for cost-effective and large-scale production of electronics. Traditional silicon chip manufacturing follows expensive and wasteful processes that are poorly suited for flexible, lightweight, or disposable applications. Printing enables new form factors by depositing thin layers of electronic materials like semiconductors, conductors and dielectrics through digital and additive processes like inkjet, screen, gravure and roll-to-roll printing. This opens opportunities across industries seeking low-cost electronic components for applications like wearables, Internet of Things devices, medical sensors, and more.

Flexible Displays Lead Commercialization

South Korea became an early leader in commercializing printed organic light emitting diode (OLED) displays. Companies like Samsung Display invested billions developing printing capabilities to mass produce flexible AMOLED displays for smartphones and other devices. In 2019, Samsung launched its first folding smartphone with a printed flexible display, demonstrating how printing unlocked new smartphone form factors. LG Display and others also commercialized printed OLED production. This solidified South Korea's position as a global leader in printed flexible displays.

South Korea Printed Electronics Industry Enable New Health Applications

Printed sensors leverage printing methods to produce thin, flexible electronic components like electrodes and circuits. This enables applications like health monitoring patches and stickers. For example, South Korean firm Nextx produces printed biosensors for continuous glucose monitoring and other health parameter measurements. Their technology deposits sensing components directly on adhesive patches using printing techniques. This opens opportunities for low-cost, continuous at-home health monitoring applications. Researchers are also exploring printed temperature, ECG and other sensor technologies for integration into clothing, bandages and more.

Advancing Printed Photovoltaics

Inkjet printing shows promise for producing low-cost thin-film solar cells as a complement to silicon wafers. Researchers at KAIST and other Korean institutions helped pioneer printing methods for depositing semiconductor inks to generate photocurrent. Companies like Hyperion Materials & Technologies and ITL Solar now offer commercial printed perovskite and organic photovoltaic (OPV) modules. Their technology enables applications like building integrated photovoltaics (BIPV) by printing solar cells directly onto glass, metal or other surfaces during construction. This could help reduce dependency on silicon-based solar panel imports over time.

Driving Roll-to-Roll Manufacturing Scale Up

Most printing processes are well-suited for roll-to-roll manufacturing, which allows for continuous, high-volume fabrication of electronic components like flexible circuits, displays and solar panels. Korean companies have invested heavily developing large-scale roll-to-roll systems and refining printing techniques. For example, OLEDWorks operates one of the world's largest roll-to-roll OLED display manufacturing facilities. Their pilot and commercial production lines helped advance printing yields, material efficiency and system throughput. This focus on scalable manufacturing helped establish Korea's electronics printing leadership and will be critical to realizing the commercial potential of these technologies.

With a vibrant technology sector and institutional support, South Korea is taking a leadership position driving commercial applications of printing electronics.

Overall, the transition to digital additive printing unlocks new product form factors while reducing manufacturing costs compared to traditional semiconductors. As companies scale up production and seek new use cases, printing is set to transform electronics the same way it revolutionized communication, media and design industries before it. South Korea's strengths position it to be at the forefront of this paradigm shift in electronics.
