Dongwoo Fine-Chem, the world's largest OLED display touch sensor manufacturing company, announced its new Antenna on Display (AoD) technology, a transparent antenna designed to deliver the best possible 5G coverage for smartphones and communication infrastructure. The company is demonstrating this innovation at the Mobile World Congress (MWC) 2021 in Barcelona this week.
Current 5G smartphones have mmWave antennas built into the side or the back of the device, which often causes interruptions to radio wave transmission and disruptions to 5G stability when users hold the smartphone with their hands. This makes Dongwoo Fine-Chem's AoD innovation unique, because it can be fitted on all smartphone screens, reducing disruptions.
"Technologies like augmented reality (AR) and virtual reality (VR) require mmWave 5G technology that delivers high speed and low latency, but today's version of this perfect 5G experience often falls short due to the limitations of mmWave 5G," said Rha In-ho, CEO and president of Dongwoo Fine-Chem." We are pleased to unveil our AoD technology, and we look forward to collaborating with smartphone and chip manufacturers to achieve 5G innovation together."
Millimeter waves (mmWave) are radio waves from 30-300 GHz that have a wavelength of 1-10mm. They are ideal for super high-speed 5G applications and have large chunks of spectrum available for use. However, mmWave cannot pass most solid materials effectively. Dongwoo Fine-Chem's AoD technology allows device manufacturers to install a transparent antenna on the display, which typically has the lowest possibility of users covering it with their hands, minimizing transmission interruptions and achieving a stable mmWave 5G communication. It can realize dual polarization on three frequency bands (n257, n258, n260) of mmWave 5G - these are some of the most commonly used worldwide bands. Click here to see all 5G FR2 frequency bands.
AoD technology can be utilized in various ways with ease, making it highly applicable. By applying the technology to glass windows on vehicles and buildings, signages, or streetlamps, this technology can make all these surfaces antennas which makes it easier to deploy 5G in the real world.
Dongwoo Fine-Chem is building a robust and comprehensive global patent portfolio ranging from core technologies in integrating transparent antennas with displays including OLED to antenna module composition. The company currently has or has filed about 240 patents around the world, including the Patent Cooperation Treaty (PCT) as well as the U.S., China, and Japan.
