JDI 7-inch WhiteMagicThe Xperia P remains the only handset in Sony’s smartphone portfolio to have used a WhiteMagic display. WhiteMagic adds an extra White subpixel to the usual RGB (red, green and blue) arrangement, the idea being that it can improve the brightness of the screen whilst reducing power consumption. See our previous post on WhiteMagic for an insight behind the technology.

Japan Display Inc (JDI) recently announced a new 7-inch IPS LCD module with QXGA (1,600 x 2,560 pixels) resolution and 431 PPI. The interesting part of the display is that JDI has developed local dimming backlight to the WhiteMagic LCD module. This new product can control the backlight more efficiently through the edge-lit local dimming backlight and WhiteMagic subpixel arrangement. JDI says that it reduces power consumption by 20% compared to a conventional WhiteMagic display.

JDI has started to market the module so we don’t know whether it will appear in any consumer products just yet, but you could see this appear in a smaller Xperia tablet category at some point in the future.
