Abstract: An electronic device may have an optical touch sensor that is insensitive to the presence of moisture. The display may present images through a display cover layer. A light source may illuminate an external object such as a user's finger when the object contacts a surface of the display cover layer. This creates scattered light that may be detected by an array of light sensors. A metasurface grating may be used to couple light from the light source into the display cover layer at an angle such that total internal reflection within the display cover layer is sustained across the display cover layer even when the display cover layer is immersed in water or otherwise exposed to moisture. Additional metasurface gratings may be formed on the display cover layer to redirect light propagating within the display cover layer away from edges that might otherwise defeat total internal reflection.

Abstract: A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.
