Abstract
The invention relates to a tactile or contactless user interface device (50), comprising organic semiconductor components (52) made by depositing organic conducting and semiconducting material in liquid form on a dielectric support (54).
Claims12
A touch or contactless user interface device, comprising:
- organic semiconductor components formed by deposition of organic conductor and semiconductor materials in liquid form on a dielectric support, said semiconductor components comprising an array of infrared emitters and an array of photon sensors;
- and
- a darkness sensor and means for activating the infrared emitters when the luminosity is below a threshold;
- wherein said array of photon sensors is capable of detecting variations of the shadow of an actuation member and of deducing therefrom information representative of a variation of the position of the actuation member.
