PCT No. PCT/DE89/00420 Sec. 371 Date Mar. 11, 1991 Sec. 102(e) Date Mar. 11, 1991 PCT Filed Jun. 24, 1989 PCT Pub. No. WO90/03024 PCT Pub. Date Mar. 22, 1990.A display device (16) for motor vehicles features a graphic-capable and back-lighted transflective dot matrix LCD (19) the matrix dots of which can be activated electrically by way of driver stages, whereby they represent information (29) on the LCD by contrast in brightness between activated matrix dots (22) which have voltage applied to them and the other non-activated matrix dots. In order to obtain as contrasting as possible but dazzle-free information display in bright and in dark conditions, a contrast switch-over is effected on the LCD (19) in that the driver stages of the activated and the non-activated matrix dots can be switched over in dependence on the brightness in front of the LCD (19).
