Crafted technology for making beautiful, robust and economic Touch Interfaces
The key features include:
The lower layer, whilst appearing to be completely transparent, contains a very tiny amount of light scattering dopant, which enables the lower layer to capture and contain some of the ejected light which is then attenuated as it radiates evenly in this layer. A small number of optical sensors, at the edges of the touch surface, measure the light intensities seen by each sensor and these signals are processed with Uniphy’s proprietary algorithms to determine the original location of the contact or contacts.
The thin low refractive index transparent film in between is there to contain light in both plates.
This approach enables freedom in shape and surface curvature while unifying displays and supporting transparent dials and buttons.
