1. A content display device (3) for a passenger (P) of a road vehicle (1); the content display device (3) comprising:
a support element (5) configured to be mounted on a dashboard (4) of the road vehicle (1), integral with the dashboard (4);
at least one screen (6) mechanically connected to support element (5) and configured so as to be visible to the passenger (P) while the vehicle is driven;
a filter element (7), which determines a viewing area (8), from which it is possible to view the contents while the vehicle is driven; the viewing area (8) comprising the point of view (VP) of the passenger (P) lying in a line perpendicular to the content display device and not the point of view (VDR) of a driver (DR), and wherein the filter element (7) comprises a first louver filter (9) having a thickness of greater than 3 mm and less than 5 mm and arranged inside the screen (6), thereby preventing the passenger (P) or the driver (DR) from removing or inadvertently damaging the filter (9) configured to limit the viewing area horizontally, wherein the first louver filter (9) comprises a series of bulkheads (11) vertically arranged, wherein each of series of bulkheads is perpendicular to the at least one screen having a distance therebetween and a length effective to limit the viewing area (8) horizontally and prevent the driver from viewing content displayed on the content display device;
the at least one screen (6) comprising an image generating element (13) directly interposed between two polarizers (16), wherein a bottommost polarizer of the two polarizers (16) is positioned in direct contact with the first louver filter (9);
a sensor element (14) configured to sense the amount of light present outside the road vehicle (1); and
a control unit (15) configured to adjust the brightness of the display device (3) according to what is detected by the sensor element (14), wherein correlation between the amount of light present outside the road vehicle and the brightness of the display device is not linear and is provided by a reference table.
