in Xperia P


WhiteMagic XperiaOne of the headline features of the Sony Xperia P is the inclusion of a 4-inch WhiteMagic qHD display. As the name suggests, WhiteMagic adds a white sub pixel to the traditional RGB (red, green and blue) pixels found in a traditional LCD. This four sub-pixel display (RGBW), combined with advanced algorithms, results in a display that is twice as bright using the “outdoor mode” and up to twice as power efficient using the “indoor mode” over traditional LCDs.

The way this works is that the backlight can pass through just the white pixel to represent a white colour. Traditionally, the backlight would have had to pass through all three sub-pixels in the right proportion. The Xperia P comes equipped with a sensor that will automatically adjust the settings between the outdoor mode and indoor mode to optimise the display’s power efficiency. Thankfully though you can also manually override the levels of brightness in the outdoor/indoor mode.

Sony says that the Xperia P is one of the brightest phones on the market. It is capable of 935 candela per square meter (cd/m2) , more than any other phone with the same pixel density.

  • ok..fine..we get it, it is super power efficient. buy why o why you have to go _back_ to 1350mAh battery from good ol 1500mAh. no one was going to sue Sony if their mobile work for day and half instead of almost a day!

    Sony is using different processor in Xperia U and Xperia P. Novathor is known as power efficient processor, Sony knows that the 1350 mAh will perform better with Novathor, unlike power hungry processor the snapdragon they need to put 1750 mAh battery to xperia S. So i will test how power efficient the novathor is. But i will get the Xperia S because i like the HD video calling which is missing in Xperia P.

     but at the sacrifice of the aluminum body… smart dock.. and having those crappy plastic usb/hdmi covers.. and having them on opposite sides of the phone. You would think they would design the flagship to be the best.. not design the cheap P better than the S…

  • Asad Mulla

    why doesn’t the flagship have this. Xperia S should have all the best sony has to offer.

  • jake

    xperia S isnt a flag ship . Its more like Neo / pro position .

    They will launch ION worldwide .

    Finally an actual display from Sony Japan. The other models may have “reality display” and “no air gap” but this just refers to the technology by which the digitizer is glued to the LCD panel, the panels themselves have been third party until now from various suppliers in Taiwan and China.

  •  I think a 4.3 inch screen phone with aluminium might get too heavy.  The plastic helps keep the weight down.

  • This phone have microSD slot up to 32gb. Internal is 16gb. – http://www.sonymobile.com/cws/corporate/products/phoneportfolio/specification/xperia-p

    bc, imagine if they did put a 1500Mah, that means every one has to buy it and the company would have to make profit… who would want that?
