Abstract:
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.
