Samsung held a new product launch event on August 11 and officially released the Galaxy Z Fold3. The phone supports IPX8 water resistance, features an under-display camera, and supports the S Pen stylus.
Today, Samsung Display announced that it has successfully developed a low-power OLED panel for smartphones. Samsung Display named this technology “Eco ² OLED ™”, which reduces power by 25%. This panel has been applied to the internal screen of the Samsung Galaxy Z Fold3.
Samsung Display stated that the company has developed a panel lamination structure that can replace polarizers to block external light reflections. This structure increases light transmittance by 33% while reducing panel power consumption by 25%.
The polarizer is an opaque plastic sheet that prevents light from outside the panel from irradiating the electrodes between the pixels and being reflected, thereby improving the visibility of the OLED display. Generally, when light passes through a polarizer, brightness decreases by more than 50%, resulting in reduced luminous efficiency.
To overcome the shortcomings of polarizers, the display industry has made various attempts. A person in charge at Samsung Display explained, “We have successfully developed a technology to improve light efficiency, and at the same time internalized the function of the polarizer for the first time in the industry.”
Eco2 OLED technology was first applied to the foldable display on the Samsung Galaxy Z Fold3, and it also contributed to the application of UPC (under-screen camera). Samsung Display stated that as the light transmittance of the display increases, it can provide more light to the camera module in the panel, thereby ensuring the application of UPC technology.
