The leader on the smartphone market Samsung will initiate the production of Super AMOLED Ultra HD/4K displays for mobile devices in the near future with this event likely happening this August. The new displays will bring the unseen before resolution of 3840 x 2160 pixels to smartphones and pixel density of up to 762 pixels per inch.
The new display technology will likely be featured in the upcoming 5th generation Galaxy Note phablet, which is expected in September 2015. The device will have two versions – the first one will have a 5.89-inch display at 4K resolution (748 ppi), while the second one will have a 5.78-inch dual edge display at 4K resolution and 762 ppi.
The new technology will allow much better image clarity and vividness compared to older devices. As a comparison the 4th generation Galaxy Note had a 5.7-inch sensor Super AMOLED display at QHD resolution (2560 x 1440 pixels) and pixel density of 515 ppi. Unfortunately the information above has not been confirmed as of now, so don’t rely on it too much.
