First Claim
1. An electronic display assembly comprising:
- a liquid crystal display;
a backlight placed behind the liquid crystal display;
one or more power modules in electrical connection with the backlight; and
a microprocessor in electrical connection with the power module(s) and adapted to;
determine a geographical location for the liquid crystal display;
determine sunrise and sunset times for a day based on the geographical location;
determine a present time;
direct the power module(s) to drive the backlight at a daytime level if the present time is between sunrise and sunset; and
direct the power module(s) to drive the backlight at a nighttime level that is less than the daytime level if the present time is between sunset and sunrise;
wherein the microprocessor is adapted to maintain the backlight in an on state throughout an entire course of a day.

Abstract
The exemplary embodiments herein provide an electronic display assembly having a liquid crystal display, a backlight placed behind the liquid crystal display, one or more power modules in electrical connection with the backlight, and a microprocessor in electrical connection with the power module(s). Said microprocessor is adapted to determine the sunset and sunrise times for each day and determine whether the present time is between sunrise and sunset or between sunset and sunrise. The microprocessor is further adapted to direct the power module(s) to drive the backlight at a daytime level if the present time is between sunrise and sunset, and direct the power module(s) to drive the backlight at a nighttime level if the present time is between sunset and sunrise.
