Samsung’s flagship phones in the second half of this year are the Galaxy Z Fold 3 and Galaxy Z Flip 3 folding machines with flexible screens. Galaxy Z Fold 3 uses UDC under-screen lens technology to make the inner screen more visually complete. ; However, the screen used in Galaxy Z Fold 3 not only uses off-screen lens technology, but more importantly, it introduces a new OLED structure design called Eco2 OLED, which can increase light transmission by 33% and reduce screen power consumption by 25% compared with traditional panels. .
In traditional OLED designs, the purpose of using polarizers is to prevent external light from irradiating the electrodes of the OLED pixels to affect the visibility. Therefore, traditional OLED panels will have an additional layer of polarizers to improve the visibility of the screen, but the polarizers will cause the bottom OLED panel The brightness loss is about 50%, so that the lower panel must have a higher brightness to achieve the visible brightness on the surface.
▲ Eco2 OLED technology can save the polarizer between the surface glass and improve the brightness by changing the OLED arrangement structure
It is possible to avoid the new structure Eco2 OLED from being paid tribute to competing brands. Samsung did not give too much explanation on the structure part, but emphasized that the new structure improves the luminous efficiency of OLED through a new arrangement method, which can save the traditional OLED panel between the OLED and the surface glass. The polarizer makes the screen brightness easier to penetrate, thereby reducing the need for OLED brightness and saving power. At the same time, due to the lack of a polarizing layer, Samsung is able to make the lens under the UDC technology have a better transmittance, making the UDC lens higher in light than the traditional OLED array panel.
At the same time, the registered name Eco2 OLED also symbolizes that in addition to reducing panel energy consumption, this technology also further reduces the use of plastic materials and introduces more environmentally friendly components.
