Abstract
A gray scale control system for a liquid crystal display (LCD) positioned in a vehicle may include a microcontroller unit, a filter, and a switching network. The microcontroller unit may include a PWM port that is configured to supply a PWM signal to a LCD segment of the LCD. The filter may be operable to adjust voltage applied to the LCD segment. The switching network may include a switch device that is connected to the filter. The switching network is operable by the microcontroller unit to electrically couple and decouple the filter between the PWM port and the LCD segment by way of the switch device.
