LG Display recently announced that it has developed an 18-inch flexible OLED panel as well as an 18-inch transparent OLED panel.
The flexible OLED panel can be rolled up to a radius of 3cm without its function being affected. It has a high-definition class resolution of 1200 X 810 with almost 1 million megapixels, while the panel’s curvature radius is 30R.
To create the flexible panels, LG Display used high molecular substance-based polyimide film as the backplane, rather than conventional plastic, to achieve the maximum curvature radius. The polyimide film also helped reduce the thickness of the panel to significantly improve its flexibility.
As for the transparent OLED panel, it boasts 30 per cent transmittance, which was achieved by adopting the company’s transparent pixel design technology. The haze of the panel has been lowered by using circuit devices and film components to a level of two per cent – a major advancement considering that the transmittance of existing transparent LCD panels is around 10 per cent.
In-Byung Kang, senior vice president and head of the R&D centre at LG display, said: “LG Display pioneered the OLED TV market and is now leading the next-generation applied OLED technology. We are confident that by 2017, we will successfully develop an Ultra HD flexible and transparent OLED panel of more than 60 inches, which will have transmittance of more than 40 percent and a curvature radius of 100R, thereby leading the future display market.”
