Abstract: A touch panel (10) includes a first planar substrate (30) for receiving tactile contact from one or more objects. The first planar substrate (30) is operable to guide light radiation (310) therein by total internal reflection (TIR), wherein electronic circuits (220) are provided to transmit and detect the light radiation (310) guided within the first planar substrate (30) and to detect spatial positions of the tactile contact (40) of the one or more objects by a corresponding disturbance in the light radiation (310) propagating within the first planar substrate (30). The electronic circuits (220) are implemented by way of printed and/or deposited electronic elements onto at least one of: a trim (200) of the touch panel (10), the first planar substrate (30), a second planar protective substrate (20) which is operable to provide protection to the electronic circuits (220).
