Display device having a deformable surface and position sensors

A display device including a deformable surface, comprising:

• a plurality of actuators including mobile elements that are moveable to deform the deformable surface, the mobile elements being distributed in a space occupied by the deformable surface, the mobile elements including an conductive or magnetic portion and an insulating portion in contact with the conductive or magnetic portion;
• a set of position sensors that sense a position of at least one touch, and that are distributed in the space occupied by the deformable surface;
• an elastic flexible membrane placed against the insulating portions of the mobile elements and extending through the space occupied by the deformable surface, the elastic flexible membrane being configured to accompany deformation of the deformable surface,
• wherein the set of sensors is secured to the elastic flexible membrane and regularly distributed in the space occupied by the deformable surface in an array of electricity conductors configured to accompany deformations of the elastic flexible membrane, and
• the conductive or magnetic portion and the insulating portion remain at a same position relative to each other during movement of the mobile elements.
