Abstract
The assembly includes on the one hand a first device I determining a first color, said device being formed of a liquid crystal display module (CL; CL , CL ), including at the front and at the back a linear polarizer (PAb , PAb ) selective of said first color, and on the other hand a second device II including a colored filter (Fy) corresponding to the second color. The assembly is characterised in that the axes of polarization of the selective polarizers (PAb , PAb ) are parallel to each other, in that the colored filter (Fy) includes at the front a reflective polarizer (PR ) whose axis of polarization is parallel to the axes of polarization of the two polarizers (PAb , PAb ), and at the back a reflective element (R, PR ), and in that a control unit ( ) enables a switching configuration to be defined displaying an item of information in the first color on a background corresponding to the second color or vice versa.
