After announcing the new ICS-powered Xperia lineup last month, Sony shared some details today on the new sensor-on-lens touch screen tech being built into the Xperia V. Sony described the tech as providing the same benefits to smartphones as in-cell and on-cell touch technology, which Apple is rumored to be including in the next-generation iPhone. In a blog post on the Sony Mobile Developer blog, the company explained exactly how the sensor-on-lens technology works and some of the benefits it provides to the Xperia V. Some of those benefits include better image quality, less haze, 5 percent better display luminance, and a lighter and thinner device due to an extra layer of glass being removed:
Sensor-on-lens touch technology means that the number of physical layers in the touch panel (handset stackup) is reduced, as the sensor layer is actually part of the lens itself. This in turn means that you will get better image quality, as there is no interference from the touch sensor component. There is one less layer of glass and one less layer of glue, compared to conventional touch panels… This technology also moves the image plane closer to you as a user, which makes it feel like you are actually touching the image itself. With this direct touch experience, you will get less parallax issues compared to a conventional touch panel, as the image and the point of touch are closer together in the sensor-on-lens touch screen technology.
