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.

Abstract translation: 实施例提供可以集成到电子设备中的触摸表面。 可以经由触摸表面（例如，触摸屏，键帽）接收用户输入。 触摸表面可以包括基底，用于维持基底的轮廓的刚性层，以及沉积在刚性层上的表面层，用于调节触摸表面的表面能。 基材可以用塑料制成; 刚性层可以是类金刚石碳（DLC）涂层; 并且表面层可以由含氟或富含硅的分子组成。 DLC可以通过物理气相沉积（PVD）沉积在塑料基板上，而表面层可以通过化学气相沉积（CVD）沉积在DLC上。 可以使用不同的材料层构造触摸表面，并且使用不同的方法来改善触摸表面的寿命以免反复使用和磨损。
