Dongwoo Fine-Chem, the world's largest OLED display touch sensor manufacturing company, has 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 plans to demo this innovation this summer, during Mobile World Congress (MWC) 2021.

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," added In-ho.

AoD technology can be utilized in various ways with ease, making it highly applicable. By applying the technology to facilities such as glass windows on vehicles and buildings, signages, or streetlamps, and giving them antenna function, it becomes easier to expand 5G infrastructure without any changes to the exterior.

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.
