New technology helps smartphones to have 4K resolution display using only software

Currently, the common tasks on smartphones such as watching videos, pictures, web surfing... 4K resolution display seems to be wasteful, but it’s the basis for virtual reality technology’s development. A few months ago, Sony has introduced the first smartphone using 4K resolution display of the world. However, because the battery technology has not developed so the Japanese manufacturer only allows their flagship to display 4K when watching high-quality videos and images. With other normal tasks such as web surfing, the screen of this smartphone will only display Full HD.

Recently, a group of researchers has combined with a manufacturer to successfully study a new technology which allows smartphone’s screen to display easily a 4K resolution content in a stable frame speed of 30 pfs. The unexpected thing is not only because this is an software engineering, but also because it does not consume much power thereby ensuring battery life for mobile devices. Researchers can even increase the frame speed to 60 fps when using this new technology. This could be a solution for smartphones manufacturers to consider the assurance of battery life on smartphone with high resolution screen. This tecchnology, however, has been developed since 2012. The Japanese manufacturer perfected it so it can work operation in real time mode by software without upgrading the hardware. It also means that when this technology is popular, smartphones of our time can display video and image in 4K quality instead of changing to another 4K smartphone which is really good for the users’ budget. This unique technology paves the way to the quality content can 4K popular on mobile devices. While with the common tasks on smartphones like watching videos, pictures, web surfing, 4K resolution seems to be superfluous but it is a prerequisite for the development of virtual reality technology. However, the reseachers also have a big ambition: they will not ignore the most exciting markets of the world: smart devices such as smartphones and tablets. When we use a smartphone or tablet is almost the largest energy consumption belongs to the touchscreen and backlight. With new technology configured in separated layers, it can significantly reduce power consumption to display and keep the devices running all week.
