Japan Display recently came under spotlight revealing a 12in display screen with the latest 4K resolution for the super sized tablets. The brand has continued to keep the display market on toes and has now introduced the 4K resolution screen for the smartphones.

More than full HD in smartphones

The new smartphone screen by Japan Display measures 5.4in with a resolution of 1440 x 2560 pixel along with 543ppi pixel density, which are way more than other top-of-the-class smartphones such as Samsung Galaxy S4 (1080 x 1920 resolution with 441ppi), Apple iPhone 5S (640 x 1136 resolution with 326ppi) and HTC One (1080 x 1920 resolution with 469ppi).

The smartphone display is a TFT LCD screen and comes with a 1500:1 contrast ratio, along with 160 degree viewing angle.

The tech firm has also unveiled a 6.2in display with the same resolution for smartphones. The pixel density of this screen is low (473ppi) when compared to the 5.4in smartphone, but is more than today's premium smartphones.

Speculations are being made that this WQHD display might be launched in 2014 and will be incorporated in smartphones in next couple of years, according to ZDNet.

Sony Might be the First in Line

It has been also assumed that Sony, one of the leading brands in smartphones, might be the first one to incorporate such display in its smartphones. The assumption is based on the fact that Japan Display is a collaboration between Sony, Toshiba and Hitachi, out of which Sony is the sole handset maker, reports Geeky Gadgets.

The Japanese firm is currently focussing towards Triluminous display for its Xperia smartphones. The Triluminous display is said to boost the brightness, colour vibrancy and contrasts by up to 50 percent.
