Those few devices with curved displays currently on the market use flexible OLED screens, but this might change soon. Since this approach ends up with quite expensive displays, Japan Display has introduced a 5.5-inch flexible screen that uses the older, but also cheaper, LCD technology.
According to the official press release, the technology used for this screen is known as Full Active Flex and "uses a plastic substrate for both sides of the liquid crystal layer." Thanks to its ability to support a refresh rate as low as 15 Hz, this display allows for a significant drop in power consumption.
The 5.5-inch display that uses Full Active Flex has a typical contrast ratio of 1,500:1 and 500 cd brightness. It has a full HD resolution and offers a density of 401 ppi, so it definitely will not be used for high-end devices. Sadly, mass production is not expected to start before the end of the year.

In my early school days, I hated writing and having to make up stories. A decade later, I started to enjoy it. Since then, I published a few offline articles and then I moved to the online space, where I contributed to major websites that are still present online as of 2021 such as Softpedia, Brothersoft, Download3000, but I also wrote for multiple blogs that have disappeared over the years. I've been riding with the Notebookcheck crew since 2013 and I am not planning to leave it anytime soon. In love with good mechanical keyboards, vinyl and tape sound, but also smartphones, streaming services, and digital art.
