Japanese electronics giant Toshiba has unveiled a 6.1-inch display with an incredible 2560 x 1600 resolution.

The LCD panel features a 498 pixel-per-inch (ppi) which is well in advance of the previous leading iPhone 4/4S display's 330 ppi display.

Based on low-temperature poly-silicon (LTPS) thin-film transistors on a glass substrate, the display will offer a 1000:1 contrast ratio and 176 degree viewing angles in the horizontal and vertical.

On a web page on the firm's mobile display web site, Toshiba showed the effectiveness of the resolution with highly detailed Japanese Kanji with characters just 3mm across.

It's not known what plans Toshiba has for the display. Indeed the size is somewhat unusual, too big for a phone and on the small side for a tablet.
