[Asia Economy Reporter Jeong Hyunjin] Samsung Display announced on the 16th that it has succeeded in developing a low-power smartphone OLED panel by creating a panel stacking structure that blocks external light reflection instead of using the polarizer, a core material of displays.

The polarizer is an opaque plastic sheet that prevents light coming from outside the panel from reflecting off the electrodes between pixels, thereby enhancing the visibility of OLED displays. Generally, when light passes through the polarizer, brightness decreases by more than 50%, resulting in reduced optical efficiency. To overcome the drawbacks of polarizers, the display industry has made various attempts.

The smartphone OLED panel technology developed by Samsung Display this time is the industry's first to internalize the polarizer function while improving optical efficiency. Through this, light transmittance increased by 33% and panel power consumption decreased by up to 25%. Samsung Display has branded this technology as 'Eco²OLED™' and recently completed trademark applications in seven countries including Korea, the United States, the United Kingdom, China, and Japan. 'Eco²OLED™' signifies an eco-friendly component that reduces the use of plastic material parts along with low power consumption.

The 'Eco²OLED™' technology was first applied to Samsung Electronics' recently unveiled 'Galaxy Z Fold3' foldable display and also contributed to the implementation of UPC (a technology that places the camera module under the panel). Samsung Display explained that as the display's light transmittance improved, more light was delivered to the camera module under the panel, enabling the securing of UPC-based technology.

Kim Seong-cheol, head of Samsung Display's Small and Medium Business Division, said, "'Eco²OLED™' is a revolutionary technology that improves the panel's optical efficiency and power consumption by changing the basic structure of OLED," adding, "Samsung Display plans to continue efforts to reduce panel power consumption through innovative driving technology and organic material optimization in line with the expansion of 5G and large-screen foldable smartphones."
