摘要

The module (3) has a backlight (5) arranged between a reflector (7) and an LCD-display (6). The backlight comprises multiple LEDs arranged in rows, where the LCD-display is illuminated from behind by the LEDs. The reflector is provided with electrochrome layers (7a), which are switched row-wise corresponding to the number of LED-rows. A backlight-control (2) switches the rows of electrochrome layers synchronously with the LEDs rows of the backlight.
