LG Display unveils 18“ flexible and transparent OLED panel
LG Display, a producer of display technologies based in South Korea, recently announced that it has developed a 18-inch flexible OLED panel that is rollable as well as a 18-inch transparent OLED panel. With these new panels the company wants to show that it has already acquired fundamental technologies to lead the large-sized flexible and transparent display market.
The flexible OLED panel has a high-definition class resolution of 1200x810 with almost 1 million mega-pixels. The panel’s curvature radius is 30R. It can be rolled up to a radius of 3cm without affecting the function of the display. In its production the experts used high molecular substance-based polyimide film as the backplane of the flexible panel instead of conventional plastic to achieve the maximum curvature radius. The polyimide film also helped reduce the thickness of the panel to significantly improve its flexibility.
The transparent OLED panel boasts 30 percent transmittance, which was achieved by adopting the company’s transparent pixel design technology. LG Display has successfully lowered the haze of the panel which is generated by using circuit devices and film components to a level of 2 percent.
