Phew! Trust the Japanese to take breakthrough tech and make it small enough to put into your pocket. The recently launched Google Nexus 10 made by Samsung, rock 2560×1600 resolution display at a staggering 300 PPI, which is unarguably the highest resolution available currently on  any tablet.
Well, it turns out that a display tech company from Japan, aptly named JDI for Japan Display Inc, has come up with a Full HD LCD display, just 4.3 inches in size, but at 1920×1080 resolution and rocks a PPI value of 503. Can you beat that? To add to this feat, JDI is said to be adopting a different kind of pixel brightness tech – RGBW, which reduces the power consumption to half of the conventional LCD display at the same brightness level.
If just this wasn’t enough, JDI has also developed a 7-inch high resolution display which resolves at 2560×1600 – same as the Nexus 10. However, and hold your breath now, JDI’s display is packed with a whopping PPI or pixel density of 431! which is far higher than the 300 PPI on the Nexus 10. Imagine a display like that on the Nexus 7. I’m already drooling.
JDI is a joint venture between Hitachi, Toshiba & Sony, all pioneers in  the Japanese high-tech electronics space. The new JDI displays are likely to be adopted in future Sony Xperia phones, and I’m beginning to wonder if a bit of this hasn’t already found its way on the rumored Sony Yuga.
