JDI's frugal 7
The joint-venture of Sony, Hitachi and Toshiba - Japan Display Inc. (JDI) - is on a roll lately. After announcing the first 4K 10" tablet panel, at the SID display expo, JDI will showcase a 7" one with up to 1000 nits of peak brightness, yet a greatly reduced power consumption.

The 7-incher sports 1200x1920 pixels of resolution, and is done with Sony's WhiteMagic technology that adds an extra white pixel to the traditional red, green and blue setup. The RGBW matrix lets the display draw up to 40% less power than conventional LCD screens when indoors, while still offering the very good 500 nits of maximum brightness then. 

At the same time, on account of the "high permeability of the RGBW pixels," peak brightness outdoors can receive a twofold boost, reaching up to 1000 nits, and making the display visible even in direct sunlight, which should bode well for all beachgoers. In this ultra high brightness mode, the 7" display will still draw as much power as a conventional LCD panel outdoors, so on average the battery life of a tablet equipped with this screen, will still be much better than the typical endurance range.
