| 摘要 |
The invention concerns a display device comprising: at least one so-called upstream filter (212, 214) bearing a message to be displayed, a light source (230, 232, 240) adapted to illuminate each said filter through backlighting, a partly reflecting element (211) located downstream of at least one upstream filter such that, when the light source is switched off, the message borne by each upstream filter, masked by the partly reflecting element, is not visible and, when the light source is switched on, a message borne by an upstream filter is visible. In some embodiments, the partly reflecting element is integrated in the second filter or located upstream of the second filter such that, when the light source is switched off, the message borne by the second filter is visible and, when the light source is switched on, a message borne by an upstream filter is visible. In particular embodiments, the partly reflecting element is integrated in one of said filters, the outline of the message to be displayed being defined by the outline of a partly reflecting zone integrated with said filter. |
