Abstract
The invention is directed to an electronic multidigit display device illuminatable by means of light sources intended for a taximeter for indication of a trip price, of a possibly occurring surcharge as well as for superposition of stored data. The display device (3) is composed of a transflecting liquid crystal display (37) (LCD), a frame (38) as a common receptacle of the liquid crystal display (37) and a light conducting plate (43) and contact elements (39) for electrically connecting the liquid crystal display (37) with actuation lines (40) on a printed circuit board (2) and a hood (42) surrounding the frame (38) and provided with detent elements (41). By means of the hood (42) the complete display device (3) can be plugged into the printed circuit board and detented with same in a correct position with simultaneous completion of all line connections. The display device (3) is designed as a component intended specifically for the printed circuit board and for application in a taximeter device.
