Dongwoo Fine-Chem to Unveil the World's First Transparent, On-Display Screen mmWave Antenna for 5G at MWC 2021

The company will demonstrate an Antenna on Display (AoD) that achieves dual polarization on three of the most commonly used mmWave 5G frequencies around the world.

SEOUL, South Korea, June 24, 2021 /PRNewswire/ -Dongwoo Fine-Chem, the world's largest manufacturer of TFT display and touch sensors, announced today the introduction of its Antenna on Display (AoD) technology, a transparent antenna designed to provide the best possible 5G coverage for smartphones and communication infrastructure. The company intends to demonstrate this innovation this summer at the Mobile World Congress (MWC) in Barcelona.

Current 5G smartphones have mmWave antennas built into the side or back of the device, which frequently causes interruptions in radio wave transmission and disruptions in 5G stability when users hold the smartphone in their hands. Dongwoo Fine-Chem's AoD innovation is unique in that it can be installed on any smartphone screen, thereby minimizing disruptions.

Technologies such as augmented reality (AR) and virtual reality (VR) require mmWave 5G technology, which provides high speed and low latency. However, the current version of this perfect 5G experience frequently falls short due to the limitations of mmWave 5G, according to Rha In-ho, CEO and president of Dongwoo Fine-Chem. We are excited to share our AoD technology with the world, and we look forward to working with smartphone and chip manufacturers to advance 5G innovation together.

Millimeter-wave (mmWave) is a radio wave with a frequency of 30-300GHz and a wavelength of 1-10mm that has been perfected to achieve super high-speed 5G while maintaining a wide bandwidth at the same time. However, mmWave is unable to effectively pass through most solid materials. Dongwoo Fine-Chem's AoD technology enables device manufacturers to install a transparent antenna on the display, which has the lowest likelihood of being covered by the user's hands. This reduces transmission interruptions and increases the likelihood of achieving stable mmWave 5G communication. It is capable of achieving dual polarization on the three mmWave 5G frequencies (n257=26.5–29.5GHz, n258=24.25–27.5GHz, and n260=37–40GHz) that are the most widely used around the world.

AoD technology can be used in a variety of ways with relative ease, making it highly applicable. By applying the technology to existing infrastructure, such as glass windows on vehicles and buildings, signage, or streetlamps, and equipping them with antenna functions, it becomes easier to expand 5G infrastructure without making any changes to the exterior.

Dongwoo Fine-Chem is developing a robust and comprehensive global patent portfolio that includes core technologies for integrating transparent antennas with displays, including OLED displays, as well as antenna module composition. The company currently has or has filed approximately 240 patents around the world, including the Patent Cooperation Treaty (PCT) as well as the United States, China, and Japan.

Dongwoo Fine-Chem is the world's largest company in the field of touch sensors for OLED displays. It was established in Korea in 1991 as a subsidiary of Japan's Sumitomo Chemical Corporation. The company has produced high-purity chemicals, high-purity alumina, touch sensors, polarizing film, and color filters for semiconductors and LCD and TFT display, among other things. Dongwoo Fine-Chem, in collaboration with local universities and businesses, has secured original and exclusive antenna design technologies, including the world's only design and manufacturing technology for transparent antennas that can be integrated with displays.

Dongwoo Fine-Chem recorded sales of approximately USD 2.7 billion (KRW 3 trillion) in the 2020 fiscal year (April 2020 to March 2021).
