Sony's late 2012 Xperia smartphones are about to hit store shelves in Europe, and among them is the LTE-capable Xperia V, a 4.3-incher with similar internals to the larger Xperia T. One feature that's unique to the V, however, is Sony's "sensor-on-lens" screen technology, which integrates touch sensor directly onto the surface of the display. Similar techniques like have been employed by manufacturers like ASUS in the Nexus 7, and Apple's iPhone 5 is widely rumored to have similar tech lurking within its display.
The result of combining these parts into a single layer is a brighter display -- Sony estimates a 5% improvement in luminance -- with less distortion when viewing the screen off-angle. The closeness of the touch sensor to the display, Sony says, should also remove the parallax effect involved with using traditional touchscreens.
The Sony Xperia V should arrive sometime in Q4. Unlike the xperia T, we've yet to hear any specifics regarding pricing of launch markets.
