Description

Sony Xperia U is a stylish and compact handset, and one of its biggest virtues seems to be customization. That is why the designers called it Xperia U, from well... "you". You can quickly swap the bottom cap in something of different color, if you are so inclined, to match your playful or business mood and time of the day. Not only that, but there is this color matching illuminated bar at the bottom, which is the trademark of the new "Iconic Identity" style of the upcoming Xperias. It is transparent, but yet full of LED light of different colors, and also houses the antenna for better connectivity.

  • Technology:

    Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.
