Screen display technology has evolved a lot in the recent past, with many flagship smartphone manufacturers now pushing for Ultra HD 4K screens on their devices.
However, there is a price that comes with the beauty of having a 4K display screen on your phone – the screen is a power hog and the devices that come with it are priced heftily. While it seems impossible to reduce the cost of 4K screens, there is a group of experts from Fujitsu and Kogakuin University in Japan that are working on lowering the amount of battery power that 4K screens do consume.
The electronic maker and the University have come up with a new software application that can upscale video playback on phones to a 4K resolution, or rather, 3,840 by 2160 pixels. With the new tech, it will be possible to display UHD at 30fps with no need of increasing the battery consumption that is usually observed in some of the devices already with this technology. Other than this, there is confirmation that it will be possible to increase the video frame from 30fps to a more fluid 60fps.
Sony’s Xperia Z5 Premium is the only smartphone with support for 4K resolutions; however, this is expected to change shortly as more premium smartphone manufacturers move towards this direction. Since the ability to output 4K content means a device’s battery life will be consumed in large amounts, Sony designed the Xperia Z5 Premium only to do this when playing media and not in normal browsing sessions. The innovation means that this UHD-associated negative will be done with very soon.
A long journey it has been
The journey into the research on how to upscale video playback into 4K output started back in 2012. Since then, the technology has been used with Keisoku Giken’s FE super resolution devices that are meant for converting video shot using professional cameras into 4K. The role of Fujitsu has only been to help simply and improve the tech, which means it can now be implemented in smartphones using a software application and without the need for any hardware or accessories.
While there is huge doubt that 4K screens will soon come at a bargain price, the discovery by Fujitsu and Kogakuin University could just be the way for manufacturers to come up with simple and cheap smartphones with 4K ability.
