Abstract
An electronic device may have image transport layer material such as coherent fiber bundle material or Anderson localization material. The image transport layer material may overlap optical components. Optical sensor components can emit and/or detect light passing through the image transport layer material. Optical components such as light-emitting diodes may emit light through image transport layers. An image from a display may pass through an image transport layer. Infrared light-emitting diodes, infrared photodetectors, and/or other optical sensor components may be used to form a two-dimensional optical touch sensor that is configured to gather touch input from an external object such as a finger of a user. The optical touch sensor may operate through an image transport layer.
