JDI announces a 7" display with 1000 nits of peak brightness, and 40% lower power draw

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.The 7-incher sports 1200x1920 pixels of resolution, and is done with Sony's
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.

Very impressive efficiency and brightness However, My brother has a Xperia P, it has a 700 nits IPS WhiteMagic display, it has an issue where at 80% brightness or higher it looks very washed out and looks like it a white filter over the screen But then again, I guess with a 1000 nit display you could probably see it almost any conditions at only 50% brightness And the Xperia P is from 2012, so their WhiteMagic tech would defiantly have improved since

if I remember correctly, Sony's Whitemagic displays all had horrible problems a while back, where the extra white pixels completely washed out colors and ruined color accuracy, hope they've sorted those issues out. :)

i thinks it is imposible to solve it if using same method since lcd(or so called led lcd) has a back lightning,means all pixel colour are always "Bright"(even black colour) and the white pixel just produce only white colour,and means the white colour always "Bright",and colour saturation on lcd/led is just well saturated(most just about 100% gamut),so when the screen too bright,will decrease colour saturation and will causing the colour look washout also the lcd/led display 's pixel is cannot "turn off" themselve like what OLED display can, so i think it is impossible to solve this issue if the panel is LCD/LED and this kind of technology, i thinks it only useful for OLED display, since oled display colour saturation is oversaturated(if without some tweak), and the white pixel's brightness can reduce the saturation,make the colour more natural and make the display bright(dim also the oled display weakness) i hope you understand my broken english,if i am wrong feel free to correct me :D

I'm always a bit of a skeptic when it comes things like this..... I'd rather wait and witness if these can actually deliver Have you ever got blown away by Ultra pixel? Triluminous/Bravia? Isocell?
