SEOUL -- An organic light-emitting diode (OLED) technology used for a foldable display in Samsung Electronics’ new smartphone, Galaxy Z Fold 3, improves the panel's transmittance rate by 33 percent and consumes up to 25 percent less power compared to previous versions with a traditional polarizer. The result is a brighter screen that drains less battery.

Since a traditional polarizer adds a dark layer of film on top of the panel, devices require more light and power to effectively display, with the transmittance rate reduced by over 50 percent. Samsung Display, a flat panel maker affiliated with Samsung Electronics, has unveiled its new OLED technology called "Eco2 OLED."

Samsung Display said the new OLED technology minimizes reflection by leveraging its innovative pixel structure and eliminates the need for an additional polarizer layer, which is an opaque plastic sheet typically attached to displays to prevent the panel from reflecting external light, while increasing contrast and improving visibility.

The company said that Eco2 OLED would cater to an ever-growing demand for low-power consumption in the 5G era. "With the shift to 5G and devices with larger, foldable screens, the industry needs energy-efficient components that offset the battery life concerns that these technologies can bring," Samsung Display's mobile display business head Kim Sung-chul said in a statement on August 16.

Eco2 OLED offers an improved under-panel camera (UPC) and allows for the first UPC on a foldable device with a seamless display that eliminates the need for distracting camera notches and bezels, Samsung Display said, adding the UPC is the closest solution for a perfect full-screen display, allowing for entirely new consumer experiences and playing a crucial role in commercializing UPC technology across the global mobile industry.

The Eco2 OLED panel optimizes pixel density and increases transmittance on the camera module. With minimal pixels applied on top of the camera hole, Samsung Display said Eco2 OLED provides a true full-screen design and increases a viewable area, allowing users to have an unbroken canvas to access their favorite apps, entertainment, and games.
