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; CL1, CL2), including at the front and at the back a linear polarizer (PAb1, PAb2) 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 (PAb1, PAb2) are parallel to each other, in that the colored filter (Fy) includes at the front a reflective polarizer (PR1) whose axis of polarization is parallel to the axes of polarization of the two polarizers (PAb1, PAb2), and at the back a reflective element (R, PR2), and in that a control unit (7) 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.
A two-colour display assembly including on the one hand a first device determining a first colour, said device being formed of a liquid crystal display module, the switching configurations of which are determined by an electronic control unit powered by an energy source, said module including a first linear polariser at the front and a second linear polariser, at least one of the two polarisers being selective of said first colour, and on the other hand a second device II including a coloured filter corresponding to the second colour, wherein the axes of polarisation of the polarisers of the first device are parallel to each other, in that the coloured filter of the second device includes at the front a reflective polariser whose axis of polarisation is parallel to the axes of polarisation of the two polarisers of the first device I, and at the back a reflective element and in that the control unit enables a switching configuration to be defined displaying an item of information in the first colour on a background corresponding to the second colour or vice versa.
