There are a number of tablets on the market today with high pixel counts including Apple's 9.7 inch, 2048 x 1536 pixel iPad screen and Google's Nexus 10.1 inch, 2560 x 1600 pixel display.
However, even higher resolution tablets may be on the way equipped with 3840 x 2160 displays, such as the one recently showcased by Japan Display.
As Liliputing's Brad Linder notes, the new display (which also appeared on Engadget) offers 438 pixels per inch - allowing users to have just as many pixels on a handheld tablet as on a 4K Ultra HD television.
"Japan Display says its screens use low-temperature poly silicon (LTPS) technology to keep power consumption low while offering high pixel density," he explained.
"The screen is an IPS display with viewing angles of at least 160 degrees, [with] a contrast ratio of 1100:1."
The screen consumes approximately 2180mW of power, the majority of which is drawn from the backlight.
