Liquid-crystal display device, e.g. for use in motor vehicle dashboard comprises positive and negative display zones combined in same display screen

摘要

The display device with monochromatic liquid crystal is of a polarizer type and comprises one positive and one negative display zone combined in the same display screen. The device comprises a polarization film on one face, and the display zones are obtained by a crossing of the polarization directions of the two zones of the film at 90 degree angle. The first zone is in the form of a wide strip, and the second zone is in the form of a narrow strip, as in a first embodiment; or the first zone is inserted in the second zone, as in a second alternative embodiment. The device comprises a display of the vehicle velocity in the first zone. In particular, the device comprises a petrol tank/reservoir gauge (E), a thermometer (T), a rev counter/tachometer (C), a velocity-meter/tachometer (V), a distance-meter/pedometer (D), a doors-closing indicator (F), and a gearbox indicator (B). The device also comprises a third zone interposed between the two zones whose display is inverted with respect to the second zone.
