Contactless user interface having organic semiconductor components
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 ).
1. 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.
2. The device of claim 1 , capable of deducing from said shadow variations information representative of a variation of the distance between the actuation member and the sensor array.
3. The device of claim 1 , capable of deducing from said shadow variations information representative of a variation of the position of the actuation member parallel to the sensor array.
4. The device of claim 1 , having no optical system between the sensor array and the actuation member.
5. The device of claim 1 , wherein a translucent protection layer coats the sensor array.
6. The device of claim 1 , wherein the surface of the sensor array is higher than the surface of the actuation member in front of said array.
7. The device of claim 1 , wherein the actuation member is at a distance greater than ten centimeters away from the sensor array.
8. The device of claim 1 , wherein the dielectric support is made of a material from the group comprising glass, plastic, paper, cardboard, and fabric.
9. The device of claim 1 , wherein said components are formed at a temperature smaller than 150° C. and at atmospheric pressure.
10. The device of claim 1 , wherein said semiconductor components comprise a light-emitting display pixel array.
11. The device of claim 1 , further comprising a darkness sensor and means for activating the infrared emitters when the luminosity is below a threshold.
12. An interactive display surface comprising the device of claim 1 , said device comprising display means and at least one photosensitive presence sensor.
