Monochromatic display device with a backlight, motor vehicle and method for operating a monochromatic display device

摘要

The device has a liquid crystal display (3) and a backlight (4) that is provided to backlight the display. The backlight has two yellow LEDs (7, 8) that emit yellow color and red LED (9) that emits red color, and light conductors (5) that are coupled with the LEDs. The conductors are arranged in parallel behind the display such that areas of the display assigned to the conductors backlight with the respective colors. The conductors are separated from each other by a photoresist layer (15) and/or light reflecting layer, where the layers are thin foils or are superimposed by a color print. An independent claim is also included for a method for operating an indicator device of a motor vehicle such as passenger car.
