DISPLAY SWITCH UNIT FOR A VEHICLE AND METHOD FOR PRODUCING THE DISPLAY SWITCH UNIT
First Claim
1. A display switch unit for a vehicle comprising:
- a first light guide plate having a first light source disposed at an edge side;
a second light guide plate having a second light source disposed at the edge and disposed on the first light guide plate;
a plurality of switch symbols disposed in the first light guide plate and the second light guide plate; and
a plurality of proximity sensors having a sensor structure,wherein the sensor structure is assigned switch symbols in both light guide plates,wherein a material of the plurality of switch symbols comprises a plastic with a plurality of light-sensitive nanoparticles, andwherein the plurality of light-sensitive nanoparticles are distributed in the first light guide plate and the second light guide plate such that under edge-side irradiation the plurality of switch symbols are visible illuminated in color and three-dimensionally.

Abstract
A display switch unit is provided for a vehicle comprising at least one first and one second light guide plate with first and second light sources disposed at the edges. The light guide plates have switch symbols and proximity sensors having sensor structures. The first light guide plate and the second light guide plate are disposed on one another. Respectively one sensor structure is assigned two switch symbols in both light guide plates. The material of the switch symbols is a plastic with light-sensitive nanoparticles, which is arranged distributed in the light guide plates in such a manner that under edge-side irradiation the switch symbols are visible illuminated in color and three-dimensionally in the light guide plates.

13. A method for producing a display switch unit for a vehicle, comprising:
-
producing dimensionally stable three-dimensional transparent plastic switch symbols formed at least partially of a plastic compound that comprises a plurality of light-sensitive nanoparticles that are configured to light up in color when excited; embedding the dimensionally stable three-dimensional transparent plastic switch symbols in a first light guide plate and as second light guide plate; applying a transparent electrically conducting coating to a rear side of the first light guide plate and the second light guide plate; structuring the coating to form sensor structures of proximity sensors; assembling the first light guide plate and the second light guide plate with a switch symbol and a sensor structure. - View Dependent Claims (14, 15, 16, 17, 18, 19)
