Abstract
Embodiments provide a touch surface that can be integrated into an electronic device. User input can be received via the touch surface (e.g., a touchscreen, a key cap). The touch surface can include a substrate, a rigid layer for maintaining the contours of the substrate, and a surface layer deposited over the rigid layer for adjusting the surface energy of the touch surface. The substrate can be made with plastic; the rigid layer can be a diamond-like carbon (DLC) coating; and the surface layer can be comprised of fluoro- or silicon-rich molecules. The DLC can be deposited over the plastic substrate via physical vapor deposition (PVD) while the surface layer can be deposited over the DLC via a chemical vapor deposition (CVD). The touch surface can be constructed using different layers of material and using different methods to improve the longevity of the touch surface against repeated use and wear.
