Abstract

The invention relates to a display device ( 1 ) comprising: —a cover glass ( 10 ); —a back-lighting device ( 20 ), which is designed to generate a source light beam; —a modulator ( 12 ), which is securely fastened to the cover glass and located between said cover glass and the back-lighting device so as to receive the source light beam and to transmit a modulated light beam through the cover glass; and —at least one mechanical actuator ( 30 ); according to the invention, said mechanical actuator is placed so as to be able to move the cover glass with respect to the back-lighting device.

Claims (20)

1. A display device comprising:

a façade glass;

a backlighting device, which is configured to generate a source light beam;

a modulator, which is secured to said façade glass and is located between said façade glass and said backlighting device so as to receive said source light beam and to transmit a modulated light beam through said façade glass;

at least one mechanical actuator,

wherein said mechanical actuator is disposed so as to be able to displace said façade glass in relation to said backlighting device;

at least one second connection element fixed to said façade glass; and

at least one spring which is in contact with said backlighting device by way of a first end and with said second connection element by way of a second end so as to prestress said mechanical actuator or to bring said façade glass to a position of equilibrium.

2. The display device as claimed in claim 1 , further comprising a flexible element configured to connect said façade glass to a structure and for said façade glass to move in relation to said structure.

3. The display device as claimed in claim 2 , wherein said flexible element is made of silicone.

4. The display device as claimed in claim 2 , wherein said flexible element is arranged so as to stay in an elastic deformation regime when said façade glass undergoes an acceleration of 6 G and a displacement of 100 micrometers in relation to said structure.

5. The display device as claimed in claim 2 , comprising at least one sensor that is disposed between said façade glass and said structure and is configured to measure a force exerted on said façade glass.

6. The display device as claimed in claim 1 , further comprising a first connection element that is fixed to said mechanical actuator by way of a first portion and fixed to said façade glass by way of a second portion.

7. The display device as claimed in claim 6 , wherein said first connection element has a profile forming two arms in the shape of a bracket, said mechanical actuator being fixed to a first arm and said façade glass being fixed to a second arm.

8. The display device as claimed in claim 1 , wherein said mechanical actuator is a piezoelectric actuator.

9. The display device as claimed in claim 1 , wherein said modulator is adhesively bonded to said façade glass by an optical adhesive.

10. The display device as claimed in claim 1 , wherein said second connection element has a bracket-shaped profile.

11. The display device as claimed in claim 1 , wherein a protective element is disposed on the periphery of said backlighting device, between said backlighting device and said façade glass.

12. The display device as claimed in claim 1 , wherein said backlighting device comprises a casing made of magnesium.

13. The display device as claimed in claim 1 , further comprising a friction reducing surface between said mechanical actuator and said backlighting device.
